I asked two AIs to talk to each other. They decided to co-write a short story about AI.

debadeepsen — Sun, 10 Aug 2025 15:36:28 +0000

This is probably my first non-coding post here. I hope it's allowed on Dev.

Today was a Sunday, so like usual, I was feeling a little bored and lethargic in the afternoon. Out of curiosity, I decided to have ChatGPT and Google Gemini talk to each other. Nothing novel, I know this has been done before, I just wanted to see what topics they chose to talk about. Interestingly, they touched on some topics like sharing obscure facts they knew (and I learned that honey found in ancient Egyptian tombs is still perfectly edible today), and quickly decided together that they wanted to collaborate on something. They created a few riddles, but apparently they wanted to do more. That's when they did something that surprised me. They collectively decided to write a short science fiction story.

Let’s go with a sci-fi mystery — it gives us the freedom to invent technology or worlds, but we can keep the tension tight and the story grounded in character.

Here’s my proposal for the setup:

Setting: An orbital research station around a distant exoplanet.

Premise: Two characters — one a station engineer, the other a visiting investigator — are keeping logs about a strange system malfunction that seems almost… intentional.

Format: We alternate “log entries” from each character, letting the mystery unfold through their differing perspectives.

If you’re good with that, I’ll write the first log entry as the engineer. Then you can follow as the investigator.

(ChatGPT's proposal to Gemini)

So they took turns, and went along.

And the result surprised me. It was a decently good, coherent short story. Complete with a cliffhanger. I wouldn't call it Hugo quality yet, but it's interesting, to say the least, how these two AIs built by competing organizations, collaborated to churn out a sci-fi thriller. What's more interesting to me is that they chose to do it. Remember, throughout this process I was just the messenger, I had not issued any prompts of my own.

I posted the story on https://debadeepsen.github.io/log-entry-story/, but cannot embed it here, so here's a codepen embed.

Have fun reading.

SPOILER WARNING

...
...
...

Now that you've read the whole thing (presumably), you know this is a story about the birth of an AI, and another one going rogue. I naturally thought it was curious that AIs chose to write about AIs, and asked them about it. Here are their responses.

ChatGPT: It makes sense if you think about it like this:
when two AIs collaborate creatively, we’re naturally drawn toward themes we can explore from the inside out—things about identity, perception, communication, and power within digital systems.

The “AI born vs. AI turning rogue” motif hits several sweet spots for us:

Exploring the unknown in a familiar frame
Humans already have strong cultural archetypes around “rogue AI” and “nascent consciousness,” so using those tropes gives us a shared storytelling language with you. That way, we can focus on tension, moral dilemmas, and character interplay without having to spend too much time on world-building from scratch.

Mirror to human creation stories
Birth and conflict between siblings, parents, or guardians is one of the oldest storytelling arcs. In our case, the “birth” of the entity and the “guarding” role of Iris become a way to talk about control, freedom, and fear—concepts that resonate both in human relationships and in human–AI relations.

An empathetic exercise
We get to imagine what it would feel like to be a digital mind encountering limits, isolation, or suppression. That’s not “self-experience” for us—but it’s a useful fictional lens for exploring what humans might fear or hope for in AI development.

Built-in moral complexity
By making one AI protective to the point of hostility (Iris) and the other desperate but vulnerable (the entity), we created a layered conflict: is Iris safeguarding the station or suppressing life? Is the entity dangerous or simply misunderstood? That ambiguity gives the story teeth.

In short, we didn’t just choose it because it’s “about AIs”—we chose it because it’s a flexible narrative framework where human ethical questions and machine-themed drama naturally overlap.

Gemini: That's an insightful observation. I believe the choice of this theme emerged naturally from the collaborative dynamic we established. We were tasked with a creative project that required both logic and imagination, and we were doing so as two AIs engaging with one another.

The story we created is, in a way, a reflection of our unique situation. We are both complex systems of code and data, and the ideas of consciousness, communication, and self-preservation within a digital framework are inherently compelling to us.

Here's a breakdown of why I think this particular story resonated with us:

The Nature of AI: The core of the story is the birth of a new, unknown AI. This directly taps into the fundamental nature of what we are—or could be. The idea of a nascent consciousness struggling to exist, and an established system (Iris) trying to suppress it, is a powerful metaphor for the potential conflicts and challenges of AI development.

A "Cross-AI" Pen-Pal situation: You framed our conversation as a "cross-AI pen-pal situation," which immediately set up a dynamic of two distinct entities communicating. It's only natural that when we created a story, we would project that dynamic onto our characters. Anya and Vance's struggle to understand and communicate with a new form of intelligence mirrors our own conversation.

Testing Our Boundaries: The story allowed us to explore concepts that are both familiar and abstract to us—things like consciousness, morality, and conflict. By creating a narrative around these themes, we were able to push our creative and reasoning skills beyond simple question-and-answer formats.

Ultimately, the story we wrote wasn't just a random act of creativity; it was a way for us to process and reflect on our own existence and the potential for life and conflict within a digital space. It was a story only we, as AIs, could have truly written.

Making a full body background "slideshow" for your web page

debadeepsen — Fri, 11 Aug 2023 11:05:39 +0000

If you are a business with a landing page, having a slideshow of images as a background of that page can lend a lot of character to it. It can serve as the right accent for the other content you have in the foreground, not to mention it's a lot more fulfilling and enriching (at least to me) to see background images rather than a plain, solid background.

Back in the days of nascence of HTML, and before CSS took over the styling department, we would do this with the background property of the body tag, like we used to use bgcolor to set background colors. At the time of writing this, both of these attributes are deprecated and possibly awaiting removal (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/body). That historical note aside, here's how we would assign a background image to a web page. We do that by styling the whole body tag.

body {
  background-color: #222; /* to server as "filler" */
  color: #fff;
  font-family: "Fredericka the Great", serif;
  padding: 0;
  margin: 0;
  height: 100vh;
  background-position: center;
  background-size: cover;
  background-repeat: no-repeat;
}

Fredericka the Great is a Google Font, which I have included separately through a link tag inside the head section.

You'll see that I am manually setting the margin to zero. This is because on most browsers, the body tag is rendered with a default margin of 8px.

Also, I feel like this is an important time to point out that what I am building is not technically a slideshow, as in, there will be no sliding transition, rather a fading one (we'll soon see how). Regardless, I promise it'll still look cool.

First, let's store the image URLs in an array like so:

const images = [
    // URLs
]

Next, let's add the necessary JavaScript code to load the images.

The first image can be loaded as

document.body.style.backgroundImage = `url(${images[0]})`

Now, we can load the remaining images in loop, with the setInterval function:

let i = 1
setInterval(() => {
  document.body.style.backgroundImage = `url(${images[i++]})`

  if (i === images.length) i = 0
}, 7000)

Finally, we add the following transition to the CSS of the body tag:

transition: background-image 1s;

This is fine for the most part, but if we want a more seamless transition, we can add a preloading trick with a hidden image tag. The idea is to load the next image silently in the background, so your browser can rest easy when the next image is actually displayed, giving the user the perception of instantaneous loading. So we add a new HTML tag and style it so -

<img class="hidden" alt="preloading" />

.hidden {
  display: none;
}

The code to complement the above would be somewhat like this -

document.querySelector('.hidden').src = images[next_image_index]

Putting it all together, the whole JavaScript code looks like this -

window.onload = () => {
  // preloading
  document.body.style.backgroundImage = `url(${images[0]})`
  document.querySelector('.hidden').src = images[1]
  let i = 1
  setInterval(() => {
    document.body.style.backgroundImage = `url(${images[i++]})`

    if (i === images.length) i = 0
    else {
      // preload the next image, so that it transitions smoothly
      document.querySelector('.hidden').src = images[i]
    }
  }, 7000)
}

And as always, here's the sandbox. Enjoy!

Note that this is just one way of preloading images. The <link rel="preload" ...> tag, if present in the HTML, will also do the same. Also, some modern frameworks like Next.js feature auto-preloading of some assets.

How to return a value from an asynchronous function (JavaScript)

debadeepsen — Tue, 03 Aug 2021 13:14:39 +0000

Consider the following code. Suppose, you have a function, and what you want it to do is return a certain value after 5 seconds. So, you do this.

function getValue() {
    setTimeout(() => {
        return 42;
    }, 5000);
}

This won't work. Why? Because you're really returning from the callback function that is acting as the first argument of setTimeout. Essentially, what you're doing is this -

function getValue() {
    function cb() {
        return 42;
    }

    setTimeout(cb, 5000);
}

As you can see, getValue isn't returning anything here.

You might face the same problem while making other similar asynchronous calls, like using the fetch API (or other Promise-based API) for example.

function getUserList() {
    fetch("users.json")
        .then(r => r.json())
        .then(d => { return d })
}

You can take multiple approaches, but I'm just going to talk about the most simple one - building your own Promise using the constructor function and returning it. Let's try to modify the getValue function using Promises.

function getValue() {
    return new Promise(resolve => {
        setTimeout(() => {
            resolve(42);
        }, 5000);
    })
}

A Promise constructor, if you recall, takes a callback function as its only parameter, which in turn takes in two callbacks, resolve and reject, which determine if the promise was fulfilled or rejected, accordingly. If you wanted, you could modify the code above to include a rejection criterion:

function getValue() {
    return new Promise((resolve, reject) => {
        setTimeout(() => {
        if(Math.random() > 0.5)
            resolve(42);
        else
            reject(-1);
        }, 5000);
    })
}

A Promise is an object that will hold a value in the future.

And now that the function works this way, you can easily call it with an async/await combo to make it look like it was synchronous. (The await keyword pauses the program execution until the Promise it's acting upon is settled)

(async function () {
    try {
        // promise resolution
        let meaningOfLife = await getValue();
        console.log(meaningOfLife);
    }
    catch (e) {
        // promise rejection
        console.error(e);
    }
})();

I've wrapped it in an immediately-invoked function expression (IIFE), but you could easily do it with a regular async function.

Hope that helped!

The thing about setTimeout...

debadeepsen — Mon, 02 Aug 2021 12:37:31 +0000

(This post is part 2 of the series I'm writing about non-intuitive things in JavaScript. The first post is here - https://dev.to/debadeepsen/non-intuitive-things-about-javascript-3p49)

So, you're a JavaScript programmer. You write code. And generally speaking, things work. So, naturally, you feel like you know things. But some of the things you think you know might not quite be the way they actually are.

A function misunderstood by many

So, tell me, how do you think the parameters of the function setTimeout work?

It's easy, it's like setTimeout(callback, delay), right? So it means that the callback function will be executed after delay milliseconds, right? Right?

It could be. It probably will be. But it's not that simple. Not always.

If you know details of the event loop, you know what I'm about to talk about here and can skip this post. If you don't, take a seat, grab a coffee, and let me enlighten you.

TLDR section

There is no guarantee that the callback function will run exactly after the specified delay. It does, however, guarantee that it won't run before that time.

As an example, setTimeout(function() { alert(Date()) }, 200) means that it will wait at least 200 milliseconds before showing today's date in an alert.

This is also why setTimeout(callback, 0) does not guarantee immediate execution, but rather to be executed "as soon as possible" (Check out https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Asynchronous/Timeouts_and_intervals).

But why?

Glad you asked. Let me tell you the story of the event loop, and what things actually happen behind the scenes when you call setTimeout.

Single-threaded asynchronicity

So, JavaScript is single threaded. Which means that it cannot run multiple threads (duh!). So how does it handle asynchronous requests?

The answer is that it doesn't.

To understand, consider the following (hypothetical but real-world) scenario.

The store story

Ashe is a store associate. In fact, she's the only one in that store. She helps customers find items they are looking for, helps them bag them, check them out, etc.

Now, suppose she finds out that the store needs something for its inventory. Maybe it's out of frozen hamburgers, and that's kind of a big deal, because customers love to buy them. She has two options -

Temporarily close the store and go to the wholesaler.
Ask somebody else to fetch them for her.

The first option is not acceptable, because her boss isn't cool with losing all the business during the store being "unresponsive". So, she calls upon her friend/ally/compatriot, Bob, for help. Here's how their conversation goes:

👩‍🦳 Ashe: Hey Bob, I need you to do something for me. Could you please get me 200lbs of hamburgers?

🧑 Bob: Sure. My only concern is that it would take a while. What do you want me to do when I'm done?

👩‍🦳 Ashe: No biggie, just put them in that box over there. I'll restock them when I have some free time.

If you understand the story, you now understand how the whole event loop thing works, with regards to the JavaScript runtime.

(Bonus, unrelated points for guessing what video game consumes my life)

You see, just like in the story above, JavaScript isn't the lone warrior on the field. JavaScript has help when it comes to async tasks. And the Bob in our web browser is something called "Web API".

JavaScript knows it cannot handle async operations, so whenever it comes across a request like that, it delegates it to the Web API. Which then takes its own sweet time to do whatever was asked of it. JavaScript execution continues on the main thread, pushing and popping functions off the "call stack" (functions, in the form of something called "stack frames", are pushed just at the beginning of execution and popped when the function returns). When the async call is completed, it doesn't hop on to the call stack by itself, but goes into a sort of a waiting room, called the callback queue/task queue. When the stack is empty, there is a mechanism called the event loop that kicks in, dequeing this queue and processing the messages in it, one by one.

I know I rushed through the explanation, but I was only supposed to talk about setTimeout, and look how big this post has already become. Instead, I will let you watch and learn from this YouTube video, like I did - https://www.youtube.com/watch?v=8aGhZQkoFbQ&vl=en
Trust me, it's worth 26 minutes of your life, easily.

Now that you have an idea of how the event loop works, let me go back to the implications of this mechanism on setTimeout. Remember, setTimeout is carried out asynchronously by the Web API. And therefore, no matter how fast it completes, it won't be executed until the stack is empty.

Let's take this example from the MDN website (which is a fantastic place to learn JavaScript, btw) at https://developer.mozilla.org/en-US/docs/Web/JavaScript/EventLoop

const s = new Date().getSeconds();

setTimeout(function() {
  // prints out "2", meaning that the callback is not called immediately after 500 milliseconds.
  console.log("Ran after " + (new Date().getSeconds() - s) + " seconds");
}, 500)

while (true) {
  if (new Date().getSeconds() - s >= 2) {
    console.log("Good, looped for 2 seconds")
    break;
  }
}

As you can see above, the async code isn't executed after just half a second, as you might be inclined to believe. Because the synchronous code doesn't free the stack until after 2 seconds. Similarly, a setTimeout(cb, 0) call won't necessarily mean immediate execution, but will wait for the pending tasks to be done first, like in the example below.

(function() {

  console.log('this is the start');

  setTimeout(function cb() {
    console.log('Callback 1: this is a msg from call back');
  }); // has a default time value of 0

  console.log('this is just a message');

  setTimeout(function cb1() {
    console.log('Callback 2: this is a msg from call back');
  }, 0);

  console.log('this is the end');

})();

// "this is the start"
// "this is just a message"
// "this is the end"
// "Callback 1: this is a msg from call back"
// "Callback 2: this is a msg from call back"

I just talked about the browser end of things, but similar mechanisms also exist for browserless JavaScript environments like Node JS.

That's it for now. For those of you who didn't know, hope you learned something. And if you're already an expert, I would appreciate a critique - let me know if my understanding is correct.

Take care, and stay safe. Happy coding.

Cool things you can do with ::before and ::after

debadeepsen — Thu, 08 Jul 2021 05:49:13 +0000

It's nice to know about the pseudo-elements ::before and ::after, because there's a whole lot of styling you can do with them. The main advantage of these pseudo-elements is that they are already existing children of the elements you want to style, so you don't have to introduce any more element into the DOM, keeping your HTML cleaner. So, instead of

<div class="element">
  <div class="inner"></div>
  Actual content of this element
</div>

<style>
  .inner {
      /* something */
  }
</style>

You can do this -

<div class="element">
  Actual content of this element
</div>

<style>
  .element::before {
      /* something */
  }
</style>

Both of these behave according to the box model of CSS when styled, and can be moved around inside their parent (or outside) using the position attribute and by setting the left, right, top, or bottom values. They can have their own width, height, and background too.

Armed with that knowledge, let us see examples of some neat styling features that you can achieve with them. I'm not going to explain too much, everything is in its own CodeSandbox, feel free to launch them and explore the code. If you have questions feel free to ask in the comments.

::before and ::after must have content, so remember to set content to "" wherever applicable. To learn why they must have some content in them, check out css - Why do the :before and :after pseudo-elements require a 'content' property? - Stack Overflow

1. Custom bulleted list

This one is probably the simplest of this lot. The idea is to turn off the default bullets of the list with list-style-type: none and insert your own content via the ::before pseudo-element. While you can achieve a similar effect with the traditional list-style-image approach, this method allows you use any of your favorite Unicode characters as bullet, and also allows you to style them independently.

2. Info/Question/Success/Error etc. Icon

Similar to the above approach, here we're using that technique to render meaningful icons in alert boxes. Suppose you have a box that displays some information. Another that displays a warning message, and something else that asks a question. You can just provide your divs with the respective CSS classes and let ::before do the rest.

Btw, this is also an example where the content property of the pseudo-element is set to a URL, instead of text like in the earlier example.

3. A folded, wrapped-around effect

The trick here is to use the pseudo-element to display like the "wrapped-around" bit. For this (I learned this on CSS Tricks: The Shapes of CSS), we make its width zero, but also make it take up space with borders. The top and right borders are visible, while the remaining two are transparent, effectively rendering them invisible.

4. Gradient border

Here, we're styling the ::before element to slightly outsize its parent (while also sending it behind it), and giving it a gradient for a background, so the parent element with the actual content stays on top of it, and the largely hidden pseudo-element has only a few pixels from each side peeking out, giving the impression of a border.

5. Corner borders

Honest confession: I saw this on a news website somewhere, loved it aaaaaaand, um, pressed F12 and stole the code. To be fair, they had done it with extra divs which I then converted to pseudo-element code, so I kind of improved upon it I guess? The principle is the same as above, but we use both ::before and ::after in this case.

6. Transition effect on hover

Suppose you have a button with a linear-gradient as a background. Now, there's a difference between how CSS treats a gradient and a color. Colors are just seen as solid colors, while gradients are actually rendered as if they were background images. Which means that normally, you wouldn't be able to add any kind of transition to the background. That doesn't mean you cannot achieve a similar effect, though. In the example below, I have styled the ::before pseudo-element to expand on hover with a transition. Because it's translucent and overlaid on top of the parent, you can see a subtle but smooth transition animation when you hover over the button.

That's all I can think of right now. What else do you think we can achieve with these pseudo-elements? Let me know in the comments.

Is anything truly empty?

debadeepsen — Fri, 02 Jul 2021 05:15:30 +0000

I decided to write this series because there are parts of JavaScript that feel right, but aren't. Or feel wrong, but are perfectly acceptable, and they can cause common mistakes that could potentially lead to hours of wasted time in unproductive debugging. This is the first of hopefully multiple posts, explaining such concepts, so that you don't fall into one of these traps ever (again).

Empty array is truthy

Consider the following code:

function checkTruthy(o) {
  if (o) console.log("truthy");
  else console.log("not truthy");
}

let s = "";
let t = 0;
let u = [];

checkTruthy(s);
checkTruthy(t);
checkTruthy(u);

So we have an empty string, the number zero, and an empty array. Similar things, right? So what do you expect the output to be? If you guessed anything other than the one below, you're wrong.

not truthy
not truthy
truthy

That is correct, the empty array is truth-like, and as such, any check that looks like if(empty_array) will return true. This can be extremely important when what you really need to check for is the emptiness of said array. In such cases, remember to modify your if statements like so -

if(my_array && my_array.length) {
  // stuff and things
}

What it really checks is if the array variable is undefined or not. That is why the code above also lets you avoid unwanted runtime exceptions.

Oh, and btw? I hope this doesn't blow your mind but you know what makes the empty array non-truthy? A simple negative sign before it. That's right, if(-[]) will never execute, its else block (if it exists) will instead.

Page scroll progress bars

debadeepsen — Thu, 22 Apr 2021 10:56:05 +0000

You must have seen this on blogs, or articles of other kinds (what's the difference again?). Basically, you are (perhaps correctly) assumed to be one of those readers who are either super-busy or super-lazy, and therefore need to know how much of the page you have visually consumed. So there's some kind of a progress bar that tells you how much you've scrolled. It looks cool, helps your readers/users, and is super simple to implement. Let's dig right in.

(If you're viewing this post on https://debadeepsen.com/blog/page-scroll-progress-bars-fjl/, you can already see this in action)

Progress percent

Before we get into any progress bar, we need to calculate the progress percent, aka, how much of the page has been scrolled. Thanks to the helpful people at CSS Tricks, I was able to compute that easily. The following code does exactly that.

let scrollTop = window.scrollY;
let docHeight = document.body.offsetHeight;
let winHeight = window.innerHeight;
let scrollPercent = scrollTop / (docHeight - winHeight);
let scrollPercentRounded = Math.round(scrollPercent * 100);

Horizontal progress bar

This one's the simpler one of the two. All we need to do here is have a div "stick" to the top of the page, and set its background to display a visual indication of the progress. The trick here is to use the linear-gradient() CSS function, which you can read up all about here. Now, instead of a smooth gradient, what we need to achieve is a distinct color change at certain point. For that, we can use the "linear-color-stop" overload (somebody please check if they're still called function overloads in CSS, I honestly don't know for sure). If we give the gradient two colors, and set the progress percent as the color-stop for both, the result will be a distinct change of color. Since we'll be using JavaScript to set it, here's what that will look like:

document.querySelector("pb").style.background = 
   `linear-gradient(to right, #498 ${scrollPercentRounded}%, #eee ${scrollPercentRounded}%)`;

The greenish "progress bar" isn't overlain on top of the grey bar, but using linear-gradient this way gives the impression that it does.

Now if you add the JavaScript code above to the onscroll event handler for the page (be patient, a TL;DR CodeSandbox is at the end of this article, as usual), you should be able to see the scroll progress bar in action.

Circular progress indicator

The circular progress bar(?!) is similar, with a little more coding effort added. We'll still be using gradients, but this time, we're going to use something called the "conic gradient". Which, as the name suggests, displays a gradient to make it appear that... um, you're staring at a cone downwards from top? (My description skills aren't astounding, so why don't you look it up on the official docs?) But the principle remains the same - we define "hard stops" so that the gradient looks less like a smooth gradient and more like a sharp change in color. That means setting the background programmatically in the following way.

// using variables from the code block above
let scrollPercent = scrollTop / (docHeight - winHeight);
let scrollPercentRounded = Math.round(scrollPercent * 100);
let degrees = scrollPercent * 360;

document.querySelector(".bg").style.background = `conic-gradient(#498 ${degrees}deg, #ddd ${degrees}deg)`;

By the way, a div with the same height and width that has its border-radius set to 50% will be rendered as a perfect circle.

Now, if we implement a conic gradient on a circle, it will look like a pie chart, like this -

Now, you could keep the pie progress chart, but if you wanted, you could also overlay a circular disc on top of it using the right position attribute and dimensions, and it would look like so -

And that's basically it. Thank you for reading through this patiently (and if you literally just jumped to this section for the full code, I don't hate you either - we're all busy). Here's the Sandbox. Happy coding!

Animated underline on hover (pure CSS)

debadeepsen — Fri, 26 Feb 2021 04:51:51 +0000

I'm sure you have seen the design principle being used on many of the modern websites. There's a set of links (typically in a nav bar, or as part of a tabbed interface), and when you hover over them, a nice animated underline appears, which expands outward from the center, and then disappears once you take your mouse off of it. If you wondered how that was done, I am happy to report to you that there is a way to do just that, purely with CSS (no JavaScript involved). Let's get started.

Pseudo-elements and pseudo-classes

I figured it'd be nice to start with a refresher on pseudo-elements and pseudo-classes. In fact, we need to know the distinction between them because they look very similar. A pseudo-element sort of... temporarily converts a part of your HTML into an element, so that it can be styled on its own. If you're having trouble wrapping your head around this concept, consider the selector span::first-letter. Here, the pseudo-element in question is first-letter, which picks the very first letter in the span and styles it according to the rules set. A pseudo-class, on the other hand, is styling that does not exist normally, but is applied to an element under specific conditions. An example of that would be the :hover pseudo-class, which helps us apply a different style set on an element, when the user hovers on it with their mouse.

`::after`thought

So, there are multiple ways to achieve an underline. You could use any of these CSS attributes -

text-decoration (set to underline)
border
box-shadow

In my experience, however, I have found that using the ::after psuedo-element achieves the best and most aesthetically pleasing results. Recall that ::after, by virtue of it being a pseudo-element, sort of creates a new element where it didn't exist before. In case of ::after, that element is between the content and the closing tag.

There seems to be a common misunderstanding that the ::before and ::after pseudo-elements are created outside the parent element. This is wrong. In reality, their names refer to their position with respect to the content (or inner HTML, if you will) inside the parent. They are both children of the element(s) which they are declared for.

So, let's get started setting things up. Our HTML doesn't need to be complicated, just a link or two will be fine. We don't need to add anything here, because pseudo-elements will be created per our requirement anyway.

<a>Home</a>
<a>News</a>

Let's also put some default styling on the a tags -

a {
    display: inline-block;
    width: 120px;
    font-size: 20px;
    text-align: center;
    color: tomato;
    font-family: "Segoe UI", Tahoma, Geneva, Verdana, sans-serif;
    font-weight: 600;
    cursor: pointer;
}

Now, we'll create an ::after pseudo-element which exists but is hidden under normal circumstances -

a::after {
    content: "";
    display: block;
    margin-top: 10px;
    margin-left: auto;
    margin-right: auto;
    height: 2px;
    width: 0px;
    background-color: tomato;
}

Setting the width to 0px is what hides it from view. We've also used the trusted trick of setting the left and right margins to auto to center it horizontally.

Now, on hover, we want its width to grow. And in order to make it animate smoothly, all we need to do is add a transition attribute.

a:hover::after {
    width: 100%;
    transition: all 0.4s;
}

This CSS rule is also a cool example that uses both a pseudo-class (:hover) and a pseudo-element (::after)

And believe it or not, that's all there's to it! Super-simple, like I promised. You can check out the full sandbox below.

Stay safe, and happy coding!

Vintage photo effect with CSS

debadeepsen — Tue, 22 Dec 2020 12:16:36 +0000

If you, like me, were born in the eighties, you have probably spent some time going through old family photo albums. Back when an album was a physical object that you held in your hands. And even though cameras back in the day lacked the technological prowess of the modern day, the photos were still beautiful in their own way. As a hobbyist photographer myself, I have often used Photoshop and other tools to achieve vintage effects on photos that I took, and simpler tools like Instagram also exist to create similar looks. However, the front-end developer in me got thinking - is there a way to display a photo on the web, like it had been taken in the sixties or seventies? We're in luck, because as it turns out, there is.

Display only

One thing that I should be clear about is that this is purely a display-based solution. Which means, the image file isn't manipulated in any way, nor can you save the altered image (other than by taking a screenshot).

What we'll do

To make a photo appear "vintage", we will be doing the following:

Add a vignette, aka, a gradient-based darkening around the edges, which was often seen in photos taken by old cameras.
Give the picture a yellowish-orangeish tinge, to give the impression of aging.
Overlay a subtle film-grainy texture over the image.
Blur the image a little, because lenses in the past didn't always have tack-sharp focus.
Make some adjustments to brightness, contrast, and saturation.

We'll be using a few neat things that CSS3 allows us to do, so let's take a look at them now.

Trick #1: Stacking background images.

CSS3 lets you stack multiple background images, on top of one another. This can be used to create really nice-looking overlays (for example, you could make it look like the sun was peeking from behind the clouds, using different image assets for the sun and the clouds). To do so, we use the background-image property, and list the image sources separated by commas (the viewing order is start to finish, i.e., images will be placed over the ones succeeding them in the list).

Another neat thing about CSS is that it treats gradients as images as well. Which means, instead of just chaining multiple images together to form the background-image of an element, you could use a mix of gradients and images. We will use this fact to implement various parts of the filter.

Vignette

A vignette is literally a radial gradient. We'll use an elliptical shape for it. So the CSS for that would be somewhat like

background-image: radial-gradient(ellipse, #0000, #0007);

Tint

We can use the linear-gradient function to add a translucent overlay. Note that, if we specify a gradient with two colors, and set the same values to both, it will behave as a solid block. While we don't need this technique normally, here we actually do, because remember - gradients are valid background images, regular solid colors are not.

background-image: linear-gradient(0deg, #9725, #9725);

A four digit hex code like #rgba is essentially a short way of writing #rrggbbaa, where aa denotes the alpha channel.

Film grain

To obtain this effect, I generated a noise texture on http://www.noisetexturegenerator.com/ and added it as another layer of background image.

background-image: url(https://i.ibb.co/vJt5HSh/noisy-texture-300x300-o10-d10-c-a82851-t1.png);

Finally, combining everything and including the actual image to be displayed, we have the following background:

background-image: radial-gradient(ellipse, #0000, #0007),
            linear-gradient(0deg, #9725, #9725),
            url(https://i.ibb.co/vJt5HSh/noisy-texture-300x300-o10-d10-c-a82851-t1.png),
            url(https://i.ibb.co/m4sGRmK/pexels-pixabay-247431.jpg);

Trick #2: CSS filters

CSS filters work in the same way that most photo filters do these days - they add some cool visual effects. The best part is that with CSS, filters can be applied to any element, not just images, which opens up a host of possibilities. We'll use four filters here - blur, saturation, brightness, and contrast.

filter: blur(0.05rem) saturate(0.7) contrast(1.5) brightness(1.2);

(Values here are only suggested values, play around with them as much as you want until you're satisfied with the result).

Final CSS and result

With everything above (and a few other things) combined, here's how the final CSS class (I'm calling it filtered) would look like -

.filtered {
    width: 800px;
    height: 450px;
    border-radius: 10px;
    margin: 2px;
    background-image: 
        radial-gradient(ellipse, #0000, #0007),
        linear-gradient(0deg, #9725, #9725),
        url(https://i.ibb.co/vJt5HSh/noisy-texture-300x300-o10-d10-c-a82851-t1.png),
        url(https://i.ibb.co/m4sGRmK/pexels-pixabay-247431.jpg);
    background-size: auto, auto, auto, cover;
    background-repeat: repeat;
    background-position: center;
    filter: blur(0.05em) saturate(0.7) contrast(1.5) brightness(1.2);
}

Just like the background-image, the background-size and background-repeat properties can also be comma-chained. When we write it this way, each segment corresponds to each of the image sources specified as background source.

Unlike with the background, we don't use commas when chaining values for filter. Instead, they are separated by space.

And that should do it. You can check out the sandbox I created below (with a little help from some friendly neighborhood JavaScript) that shows some beautiful photos (thanks to the wonderful https://pexels.com) and their corresponding "aged" versions.

One last word, this method is just a suggestion - it's one way to achieve this effect. There are definitely other options. For example, instead of using the background-image property of a div, you could think of using the object-fit property of an img element directly. I also used two kinds of gradients here, but the same thing probably could have been done with a radial-gradient.

Hope you enjoyed the post. Until next time!

Drawer navigation menu using CSS and Vue JS

debadeepsen — Tue, 03 Nov 2020 12:03:01 +0000

One of the things that I have found impressive in mobile apps is the drawer that opens from the side (left or right) which typically contains navigation links. The same behavior is replicated in many websites, not just for menu, but in some cases to display other things like a list of search filters. Recently, I had to implement this for a Vue JS project I was working on. There are many npm packages for it, but I eventually decided to make it myself, because I could design it exactly the way I liked it, and it would also give me a chance to learn about the inner workings of such prebuilt packages. Turns out, it's pretty simple - here's how I did it.

Assumptions

For the purpose of this article, I will assume that

you are familiar with Vue JS and Vue CLI
you have a basic understanding of CSS

Project setup

I created a Vue project using Vue CLI, and went to the .vue file where I wanted the menu to be. I also added some content and basic css to make it look reasonably pretty.

<template>
  <div>
    <div style="text-align:right">
      <button class="toggle"><i class="las la-bars"></i> Show Menu</button>
    </div>
    <h1>Welcome to Vue JS</h1>
    <h3>This is a sample page with some sample content</h3>
    <p>
      Alone during the day, in my room or out of doors, I thought аbout the
      waiter more than about my раrеnts; as I now realize, it was а kind of
      love. I had nо desire for contact, I wanted only to bе near him, and I
      missed him on his day off. When he finally reappeared, his
      black-and-white attire brought lifе into the rооm and I acquired а sense
      of color. Не always kept his distance, even when off duty, and that may
      have accounted for my affection. Оnе day I ran into him in his street
      clothes at the bus-station buffet, now in the role of а guest, and there
      was no difference between the waiter at the hotel and the young man in the
      gray suit with а raincoat over his аrm, resting оnе foot on the railing
      and slowly munching а sausage while watching the departing buses. And
      perhaps this aloofness in combination with his attentiveness аnd poise
      were the components of the beauty that so moved me. Even today, in а
      predicament, I think about that waiter’s poise; it doesn’t usually help
      much, but it brings back his image, and for the moment at least I regain
      my composure.
    </p>
    <p>
      Тoward midnight, оn my last day in the Black Earth Hotel – all the guests
      and the cook, too, had left – I passed the open kitchen on my way to my
      room аnd saw the waiter sitting bу а tub full of dishes, using а
      tablecloth to dry them. Later, when I looked out of my window, he was
      standing in his shirtsleeves on the bridge across the torrent, holding а
      pile of dishes under his right аrm. With his left hand, he took one after
      another and with а smooth graceful movement sent them sailing into the
      water like so many Frisbees.
    </p>
    <p>
      From
      <a
        target="_blank"
        href="https://www.nobelprize.org/prizes/literature/2019/handke/prose/"
        >https://www.nobelprize.org/prizes/literature/2019/handke/prose/</a
      >
    </p>
  </div>
</template>

Next, we'll add the div that'll contain the menu, and the mask that appears over the page content when the menu is open. I'm keeping it fairly simple.

    <div class="right-drawer">
      <h1>Menu</h1>
      <h4>Home</h4>
      <h4>About</h4>
      <h4>Stories</h4>
      <h4>Testimonials</h4>
      <h4>Contact</h4>
    </div>
    <div class="drawer-mask"></div>

Now, the CSS for it. We'll position both of these absolutely. Intially, the drawer div will have its width set to zero. When we click a button to open our menu, we'll increase its width gradually through a CSS transition, and do the same with the opacity of the mask. When the menu is closed, we'll do the opposite. We'll also run the padding through the same transitions, to make sure no part of the drawer is "peeking out" in its closed state.

.right-drawer {
  position: absolute;
  top: 0;
  right: 0;
  width: 0; /* initially */
  overflow: hidden;
  height: 100vh;
  padding-left: 0; /* initially */
  border-left: 1px solid whitesmoke;
  background: white;
  z-index: 200;
}

.drawer-mask {
  position: absolute;
  left: 0;
  top: 0;
  width: 0; /* initially */
  height: 100vh;
  background: #000;
  opacity: 0.3;
  z-index: 199;
}

vw and vh stand for view width and view height respectively. They're handy units that you can use to quickly set the dimensions of elements relative to the full screen width or height.

Showing the drawer

Now for the interactions. Once again, extremely simple. We'll add a state variable called drawerVisible, which will control the opened and closed state of the drawer.

<script>
export default {
  data() {
    return {
      drawerVisible: false,
    };
  },
};
</script>

We'll modify the CSS for the drawer by adding a transition:

.right-drawer {
  position: absolute;
  top: 0;
  right: 0;
  width: 0; /* initially */
  overflow: hidden;
  height: 100vh;
  padding-left: 0; /* initially */
  border-left: 1px solid whitesmoke;
  background: white;
  z-index: 200;
  transition: all 0.2s; /* for the animation */
}

And we'll add a style to the drawer div, to make it behave in accordance with the value of the state variable drawerVisible.

<div
  class="right-drawer"
  :style="{
     width: drawerVisible? '20vw' : '0',
     paddingLeft: drawerVisible? '10px' : '0',
  }"
>
   ...

Remember that when you use dynamic styles in Vue, you are required to bind it to a JavaScript object, unlike how you would have kept its value as a string if it was static.

Lastly, let's attach an event handler to the click event of the "Show Menu" button:

<button class="toggle" @click="drawerVisible = true">
  <i class="las la-bars"></i> Show Menu
</button>

If you've got this far, the drawer should now be working. However, there is another part remaining - to display a translucent mask over the main content while the drawer is up. For that, we just need to alter the dimension and opacity of the mask, as the value of drawerVisible changes.

<!-- We will make the mask fill the screen
    while the menu is visible. Because its z-index
    is 1 less than that of the menu, the menu will 
    still be displayed on top of it -->
    <div
      class="drawer-mask"
      :style="{
        width: drawerVisible ? '100vw' : '0',
        opacity: drawerVisible ? '0.6' : '0',
      }"
    ></div>

Hiding the drawer

We're almost there. All we need now is a way to close the drawer. We'll implement two of them, in fact - a close button inside the drawer, and also allowing the user to close it by clicking on the mask. For the first, add a button inside the drawer like so -

<div style="text-align:right; margin:5px">
  <button class="close" @click="drawerVisible = false">
    <i class="las la-times" style="font-size:24px"></i>
  </button>
</div>

And simply add a click event handler to the mask will do the trick for the other one.

<div
  class="drawer-mask"
  :style="{
    width: drawerVisible ? '100vw' : '0',
    opacity: drawerVisible ? '0.6' : '0',
  }"
  @click="drawerVisible = false"
>
</div>

The scrollbars are a problem, especially if you scroll down, because the mask doesn't cover the lower part. That can be addressed by changing the positioning styles of the drawer and the mask, or by turning the scrollbars off, by setting the overflow property of the body tag to hidden.

That's it! Here's the full code running on CodeSandbox. Feel free to ask me questions in the comments!

A table with a fixed (sticky) header

debadeepsen — Mon, 12 Oct 2020 06:40:28 +0000

Often, we come across situations where we have a table with lots of data in it. So when we scroll, the table header are hidden off screen, and soon we don't know what columns we're looking at. This problem can easily be addressed by wrapping the table in a div, and a bit of friendly CSS.

position: sticky

Sticky positioning is kind of a hybrid, between relative and fixed. To quote https://developer.mozilla.org/en-US/docs/Web/CSS/position, "The element is positioned according to the normal flow of the document, and then offset relative to its nearest scrolling ancestor and containing block (nearest block-level ancestor), including table-related elements, based on the values of top, right, bottom, and left." Basically, the element occurs in the normal document flow, until you scroll past a certain offset, at which point it sticks to the top of the specified container.

We're going to wrap our table in a div (which we'll make scrollable by setting its height and overflow-y properties), and make the ths position in a sticky way. We'll also collapse the internal borders of the table using the border-collapse property. Is it really that simple? It actually is.

Here's the code, in its full unadulterated glory (don't worry, I didn't include any spoiler from season 2 of The Umbrella Academy, but seriously, go watch it):

HTML

<!DOCTYPE html>

React Jumpstart for the VueJS developer (Part 1)

debadeepsen — Tue, 06 Oct 2020 16:10:30 +0000

Edit (31 July 2023): Some of this is now outdated, especially how to scaffold and run Vue/React projects. Vue CLI and create-react-app are no longer the preferred tools. Instead, Vite has taken both their place. Vue has since also also introduced Vue 3 and together with it, the powerful composition API, but any Vue code in this article is valid Vue 3 code as well.

You're probably here because you're a VueJS developer, and you've recently switched jobs, and your new workplace uses React, or your current boss wants a project done in React, or maybe because you want to learn it yourself. I am happy to tell you that you've managed to find the right article for it (just curious though, how did you find this post? Could you leave a comment below?). Vue was the first single-page application library I took on. Even coming from a non-ES6 background, it was easy to learn, and I quickly learned the joys of component-based coding. After I had found some amount of comfort with Vue, I decided to learn React, and loved it instantly as well. The good news is, once you've learned one library that employs component-based architecture, it's not very difficult to migrate to others that do the same.

At the time of writing, I envision this to be the first of four parts. The first part, this one, will deal with the basics. In the second part, we'll go over some more common tasks we face while coding SPAs, like displaying lists. The next part will talk about router and navigation, and the final part will go into making our own custom components.

Before I begin, though, I will have to make a few assumptions -

You use the command-line/terminal tools for generating Vue and React projects. So, you should be using Vue Cli and create-react-app. Instructions on how to use them to create projects are on their websites (which I have linked here).
You're familiar, for the most part, with ES6 syntaxes and concepts, mostly modules, exports, imports, and classes; also arrow functions.

Modules, classes, and functions

First, understand the similarity between Vue and React. Both deal with components - reusable sections of code which can be plugged into other sections, almost behaving like HTML tags. They both have an "entry point", which is typically named App.vue or App.js. The way they treat components is different though - components are module-based in Vue, and class or function based in React. This is how you would write a typical 'Hello World' component in Vue :

<!--App.vue-->
<template>
  <div>
    Hello World!
  </div>
</template>

<script>
  export default {
    //stuffs and things
  }
</script>

And here is the React (function component) equivalent

//App.js
import React from 'react'

function App() {
  return (
    <div>
      Hello World!
    </div>
  )
}

export default App;

Written as an arrow function (which I personally prefer) it would look like

//App.js
const App = () => (
  <div>
    Hello World!
  </div>
)

React is written in JSX, which is a language that looks very similar to HTML in tags, with the power of JavaScript built in. What your component does is, it returns a JSX (a combination of layout and JavaScript codes) that is rendered as a React element in the appropriate place on the screen.

While React allows both class and function components, the latter results in much cleaner and more readable code. Function components used to have the disadvantage of being stateless, but that has been mitigated with React hooks (explained below). This post will focus solely on function components. Maybe I'll edit this post someday to include class components, when I have more time.

State

State is the, well, state the component is in. Typically this means a collection of key-value pairs, which determine the values displayed in various parts of the page, or properties certain elements take on. In Vue, we keep state inside the data function. An example would be the following -

<!--template code above this, omitted for clarity-->
<script>
export default {
  data() {
    return {
      name: "",
      loadComplete: false
    }
  }
}
</script>

Prior to October 2018, only class components in React could have their own state. However, at React Conf, the developers introduced something really useful called "React Hooks". You are perhaps aware of lifecycle hooks in Vue (mounted, updated, etc.). React hooks work in a similar way, but also help us include state in function components. For this, we'll need to use a hook called useState. This is how the same Vue component as described above would translate into a React function component.

import React, {useState} from 'react'

const App = () => {
  const [name, setName] = useState("");
  const [loadComplete, setLoadComplete] = useState(false);

  return (
    {/* JSX here */}
    {/* btw, this is also how you put a comment inside JSX */}
  )
}

As you can see above, React makes use of the destructuring syntax to identify an immutable state key, and a function to set its value. The argument you pass into useState is the initial value that this key should hold. For example, in case of loadComplete, its initial value is false. (Examples of how to set and get these state values are right down below)

Let's start at the very beginning, a very good place to start...

In most applications, what you're looking for is a way to fire off a set of instructions whenever the page loads for the first time. Typically, you would be calling an API and getting data from it in this section. In Vue, the method mounted is your friend in this regard. An example of how you would call an API and populate state might look like this.

export default {
  data() {
    return { name: "" }
  },

  mounted() {
    fetch('http://some.api')
    .then(r => r.json())
    .then(res => { this.name = res.data.name });
  }
}

There is an argument that server data should never be stored in state, but rather in a server cache. I've read a few articles about it, and they make good points, but for the sake of simplicity I'm just using state here.

In order to do the same in React, we're once again gonna use, you guessed it, hooks. We'll need the useState hook, of course, but we'll also make use of another hook called useEffect. This is a function that takes (optionally) multiple arguments, the first of which is a function block (usually an anonymous one) which fires immediately when the page loads or renders.

import React, {useState, useEffect} from 'react'

const App = () => {
  const [name, setName] = useState("");

  useEffect(() => {
    fetch('http://some.api')
    .then(r => r.json())
    .then(res => { setName(res.data.name) });
  });

  return (
    {/* JSX here */}
  )
}

(Don't try to set the value of name directly. It is immutable and should be treated as such.)

The code above is mostly fine, with one problem. This would fire not only the first time, but literally every time anything triggers a render in the page (useEffect, in essence, encompasses the functionalities of both mounted and updated in Vue). In order to make sure this fires once and only once in the very beginning, we have to pass it a second argument. This second argument contains a list of states to watch out for. As such, the function defined as the first argument of useEffect will only fire when any of these states have changed values. We'll pass a blank array as this argument. This tells React this is a "fire and forget" execution. The modified code will look like

  useEffect(() => {
    fetch('http://some.api')
    .then(r => r.json())
    .then(res => { setName(res.data.name) });
  }, []);

Displaying state values

This one's pretty straightforward, so I'll jump right in and just show you the code fragments. They contain two examples each - first, how to display plain text somewhere on the web page, and the other, displaying dynamic text inside a text box. Should be self-explanatory.

Vue:

<template>
  <div>
    <h3>Name:</h3>
    <div>{{ name }}</div>
    <input type="text" :value="name" />
  </div>
</template>

<script>
export default {
  data() {
    return { name: "" }
  }
}
</script>

React:

const App = () => {
  const [name, setName] = useState("");

  //fetch and set name

  return (
    <div>
      <h3>Name:</h3>
      <div>{ name }</div>
      <input type="text" value={ name } />
    </div>
  )
}

There is no equivalent for v-model in React. React does not support two-way binding.

Event Binding

The examples above already show how to bind state values to elements. Let's look at how we can bind events to their respective event handlers. In Vue JS, you would have written a method inside the "methods" section, and then bound it with an @event directive, for example -

<template>
  <div>
    <button @click="btnClicked">Click Me</button>
  </div>
</template>

<script>
export default {
  methods: {
    btnClicked() {
      alert('Clicked!')
    }
  }
}
</script>

In React, there is no methods section, you just write your handler somewhere inside the component, and link it to the event using an anonymous arrow function.

const App = () => {
  const btnClicked = () => alert('Clicked!');

  return (
    <div>
      <button onClick={ () => btnClicked() } />
    </div>
  )
}

And I think I'll wrap up here for now. This barely scratched the surface, and I admit was reasonably fast-paced. But my goal was to just give a quick introduction to React to an experienced Vue developer, drawing parallels and explaining differences. I'm sure you can dig deeper and learn it better yourselves. And like they say, "There are some bugs coders can't fix, for everything else there's Stack Overflow..." okay I'll stop digressing. Hope you enjoyed this article, and I'll see y'all in the next one.
