It's Time to Ditch Node.js - bun.js is the Future

Manitej ⚡ — Sun, 05 Nov 2023 05:43:08 +0000

Introduction:

JavaScript runtimes have come a long way in the past few years. From Node.js to Deno and many others, developers now have several excellent options for building fast and efficient JavaScript applications. One of the newest players in this space is bun.js - a fast all-in-one JavaScript runtime created by Jarred Sumner and the team at Oven.sh.

In this post, we'll take a quick look at what makes bun.js special and why you should consider it for your next JavaScript project.

What is bun.js?

Bun is a JavaScript runtime built in Zig - a low-level programming language that compiles to native code. This allows bun to execute JavaScript at near-native speeds without the overhead of compilers or interpreters.

Some key features and benefits of bun include:

Blazing fast start up and execution - benchmarks show bun starting up and running code faster than Node.js and Deno.
All-in-one runtime - bun handles everything from package management to transpilation out of the box. No need for separate build tools.
Excellent TypeScript support - bun has first-class support for TypeScript with no extra configuration required.
APIs compatible with Node.js - bun implements the native Node.js APIs which makes it easy to migrate existing projects.
Lightweight - bun has a small runtime footprint around 7 MB compared to 100+ MB for Node.js

Why Choose bun.js?

There are a few key reasons why bun.js stands out from other JavaScript runtimes:

Speed - The biggest selling point is raw speed. bun achieves incredible performance by compiling JavaScript directly to machine code using LLVM. This eliminates interpreter overhead.

Simplicity - Getting started with bun.js is simple. There's no complex configuration or build setup. Just install and start coding.

Latest JavaScript features - bun supports the latest JS features like top-level await out of the box. No need to wait for these to be implemented in Node first.

Easy migration - Using the native Node.js APIs makes migrating existing projects to bun straightforward.

Developer experience - bun provides excellent TypeScript support, fast error reporting, dependency graphs, and other features to enhance developer experience.

Summary

Bun.js brings a unique approach to running JavaScript and TypeScript outside the browser. By compiling code directly to machine language, it unlocks speed and performance not possible in traditional interpreted environments.

So if you're looking for a fast, lightweight and developer-friendly runtime for your next JavaScript or TypeScript project, give bun.js a try!

Build a Serverless REST API on AWS in under 5 minutes!

Manitej ⚡ — Thu, 06 Jan 2022 05:37:35 +0000

In this example we will look at how to create a serverless REST API on AWS using Serverless Stack (SST). If you are a TypeScript user, we've got a version for that as well.

Requirements

Node.js >= 10.15.1
We'll be using Node.js (or ES) in this example but you can also use TypeScript
An AWS account with the AWS CLI configured locally

Create an SST app

Let's start by creating an SST app.

$ npx create-serverless-stack@latest rest-api
$ cd rest-api

By default our app will be deployed to an environment (or stage) called dev and the us-east-1 AWS region. This can be changed in the sst.json in your project root.

{
  "name": "rest-api",
  "stage": "dev",
  "region": "us-east-1"
}

Project layout

An SST app is made up of two parts.

stacks/ — App Infrastructure

The code that describes the infrastructure of your serverless app is placed in the stacks/ directory of your project. SST uses AWS CDK, to create the infrastructure.

src/ — App Code

The code that's run when your API is invoked is placed in the src/ directory of your project.

Setting up our routes

Let's start by setting up the routes for our API.

Replace the stacks/MyStack.js with the following.

import * as sst from "@serverless-stack/resources";

export default class MyStack extends sst.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    // Create the HTTP API
    const api = new sst.Api(this, "Api", {
      routes: {
        "GET /notes": "src/list.main",
        "GET /notes/{id}": "src/get.main",
        "PUT /notes/{id}": "src/update.main",
      },
    });

    // Show the API endpoint in the output
    this.addOutputs({
      ApiEndpoint: api.url,
    });
  }
}

We are creating an API here using the sst.Api construct. And we are adding three routes to it.

GET /notes
GET /notes/{id}
PUT /notes/{id}

The first is getting a list of notes. The second is getting a specific note given an id. And the third is updating a note.

Adding function code

For this example, we are not using a database. We'll look at that in detail in another example. So internally we are just going to get the list of notes from a file.

Let's add a file that contains our notes in src/notes.js.

export default {
  id1: {
    noteId: "id1",
    userId: "user1",
    createdAt: Date.now(),
    content: "Hello World!",
  },
  id2: {
    noteId: "id2",
    userId: "user2",
    createdAt: Date.now() - 10000,
    content: "Hello Old World! Old note.",
  },
};

Now add the code for our first endpoint.

Getting a list of notes

Add a src/list.js.

import notes from "./notes";

export async function main() {
  return {
    statusCode: 200,
    body: JSON.stringify(notes),
  };
}

Here we are simply converting a list of notes to string, and responding with that in the request body.

Note that this function need to be async to be invoked by AWS Lambda. Even though, in this case we are doing everything synchronously.

Getting a specific note

Add the following to src/get.js.

import notes from "./notes";

export async function main(event) {
  const note = notes[event.pathParameters.id];
  return note
    ? {
        statusCode: 200,
        body: JSON.stringify(note),
      }
    : {
        statusCode: 404,
        body: JSON.stringify({ error: true }),
      };
}

Here we are checking if we have the requested note. If we do, we respond with it. If we don't, then we respond with a 404 error.

Updating a note

Add the following to src/update.js.

import notes from "./notes";

export async function main(event) {
  const note = notes[event.pathParameters.id];

  if (!note) {
    return {
      statusCode: 404,
      body: JSON.stringify({ error: true }),
    };
  }

  const data = JSON.parse(event.body);

  note.content = data.content;

  return {
    statusCode: 200,
    body: JSON.stringify(note),
  };
}

We first check if the note with the requested id exists. And then we update the content of the note and return it. Of course, we aren't really saving our changes because we don't have a database!

Now let's test our new API.

Starting your dev environment

SST features a Live Lambda Development environment that allows you to work on your serverless apps live.

$ npx sst start

The first time you run this command it'll take a couple of minutes to do the following:

It'll bootstrap your AWS environment to use CDK.
Deploy a debug stack to power the Live Lambda Development environment.
Deploy your app, but replace the functions in the src/ directory with ones that connect to your local client.
Start up a local client.

Once complete, you should see something like this.

===============
 Deploying app
===============

Preparing your SST app
Transpiling source

dev-rest-api-my-stack: deploying...

 ✅  dev-rest-api-my-stack


Stack dev-rest-api-my-stack
  Status: deployed
  Outputs:
    ApiEndpoint: https://2q0mwp6r8d.execute-api.us-east-1.amazonaws.com

The ApiEndpoint is the API we just created. Now let's get our list of notes. Head over to the following in your browser. Make sure to replace the URL with your API.

https://2q0mwp6r8d.execute-api.us-east-1.amazonaws.com/notes

You should see the list of notes as a JSON string.

And use the following endpoint to to retrieve a specific note.

https://2q0mwp6r8d.execute-api.us-east-1.amazonaws.com/notes/id1

Now to update our note, we need to make a PUT request. Our browser cannot make this type of request. So use the following command in your terminal.

curl -X PUT \
-H 'Content-Type: application/json' \
-d '{"content":"Updating my note"}' \
https://2q0mwp6r8d.execute-api.us-east-1.amazonaws.com/notes/id1

This should respond with the updated note.

Making changes

Let's make a quick change to our API. It would be good if the JSON strings are pretty printed to make them more readable.

Replace src/list.js with the following.

import notes from "./notes";

export async function main() {
  return {
    statusCode: 200,
    body: JSON.stringify(notes, null, "  "),
  };
}

Here we are just adding some spaces to pretty print the JSON.

If you head back to the /notes endpoint.

https://2q0mwp6r8d.execute-api.us-east-1.amazonaws.com/notes

You should see your list of notes in a more readable format.

Deploying your API

Now that our API is tested and ready to go. Let's go ahead and deploy it for our users. You'll recall that we were using a dev environment, the one specified in your sst.json.

However, we are going to deploy your API again. But to a different environment, called prod. This allows us to separate our environments, so when we are working in dev, it doesn't break the API for our users.

Run the following in your terminal.

$ npx sst deploy --stage prod

A note on these environments. SST is simply deploying the same app twice using two different stage names. It prefixes the resources with the stage names to ensure that they don't thrash.

Cleaning up

Finally, you can remove the resources created in this example using the following command.

$ npx sst remove

And to remove the prod environment.

$ npx sst remove --stage prod

Conclusion

And that's it! You've got a brand new serverless API. A local development environment, to test and make changes. And it's deployed to production as well, so you can share it with your users.

serverless-stack / sst

💥 SST makes it easy to build full-stack serverless apps.

This guide is meant for full-stack developers or developers that would like to build full stack serverless applications. By providing a step-by-step guide for both the frontend and the backend we hope that it addresses all the different aspects of building serverless applications. There are quite a few other tutorials on the web but we think it would be useful to have a single point of reference for the entire process. This guide is meant to serve as a resource for learning about how to build and deploy serverless applications, as opposed to laying out the best possible way of doing so.

So you might be a backend developer who would like to learn more about the frontend portion of building serverless apps or a frontend developer that would like to learn more about the backend; this guide should have you covered.

We are also catering this solely towards JavaScript developers for now. We might target other languages and environments in the future. But we think this is a good starting point because it can be really beneficial as a full-stack developer to use a single language (JavaScript) and environment (Node.js) to build your entire application.

⚡️Serverless-stack⚡️ Build full-stack serverless apps on AWS!

Manitej ⚡ — Mon, 13 Dec 2021 15:58:12 +0000

This is an introduction blog post to a new framework called SST

serverless-stack / sst

💥 SST makes it easy to build full-stack serverless apps.

What is SST?

Serverless Stack (SST) is an open-source framework that makes it easy to build serverless applications on AWS. It supports various frameworks like React, Vue, Angular, Svelte and much more!

🔥 Features

Live Lambda Development

Work on your local Lambda functions live, without mocking or redeploying your app.

Breakpoint debugging

Use your favourite IDE like Visual Studio code, WebStorm, Intellij and set breakpoints to debug your Lambda functions.

Composable serverless constructs

Higher-level CDK constructs made specifically for building serverless apps.

and much more!

✨ Examples

Okay, enough talk want to see some actual code? sure, go ahead.

Want to create a REST API?

Here you go,

new sst.Api(this, "Api", {
  routes: {
    "GET /notes": "src/list.main",
    "GET /notes/{id}": "src/get.main",
    "PUT /notes/{id}": "src/update.main"
  }
});

No REST, GraphQL please!

alright!

new sst.AppSyncApi(this, "Api", {
  graphqlApi: { schema: "schema.graphql" },
  resolvers: {
    "Query get": "src/get.main",
    "Query list": "src/list.main",
    "Mutation update": "src/update.main"
  }
});

Want user auth? it's a piece of 🍰

Here's an example code to add Facebook auth

const api = new sst.Api(this, "Api", {
  defaultAuthorizationType:
    sst.ApiAuthorizationType.AWS_IAM,
  routes: {
    "GET /private": "src/private.main"
  }
});

const auth = new sst.Auth(this, "Auth", {
  facebook: { appId: "419718329085014" }
});

// Allow auth users to access the API
auth.attachPermissionsForAuthUsers([api]);

CRON jobs?

Too easy!

new sst.Cron(this, "Cron", {
  job: "src/lambda.main",
  schedule: "rate(1 minute)"
});

// Allow access to other resources
api.attachPermissions(["s3"]);

Full-stack react app hosted on AWS?

We need 6 lines of code to do that,

new sst.ReactStaticSite(this, "Site", {
  path: "src/frontend",
  customDomain: "www.my-react-app.com",
  environment: {
    REACT_APP_API_URL: api.url
  }
});

and this is just the surface, want to explore more?

Hey guys!

I recently had a requirement to make teams from a pool of around 100 people with 5 members per team each.

Usually, it would take a lot of effort & time to make teams. But in the end, you'll be called biased anyways. That's why I want to automate this process. So I wrote a small script in python which I want to share with you now.

Requirements

Generate teams from excel sheet
Form teams of 5 members from 102 people
display the left out, 2 people
Completely random logic of forming teams

Let's get started!

Getting CSV Data from excel

I used Google Sheets to collect info, so I need to convert it to CSV.

here's the data after conversion (delete the first line, as they indicate column names)

I saved the file as data.csv

Now comes the main part! The Code :)

Code

To read .CSV files in Python we need csv package. Which is already pre-installed. This means you don't need to install anything to follow along :)

Importing packages

# To read data from CSV file
import csv
# To get random sub-data 
from random import sample

Creating lists to store data

The csv package we imported earlier converts each row in the csv file to a list.

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for i in reader:
        print(i)

The above code outputs,

As you can see it converts each row in CSV file into a python list. Awesome right?

Now I created 2 empty lists to store data

# stores the roll numbers of all members in one list
persons = []

# stores lists of teams (lists inside inside list)
teams = []

Now I only want the roll numbers of students to be in persons list. To do so we need to access it by using its index.

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for i in reader:
        persons.append(i[0])

Now comes the main part! forming actual teams.

The idea is to randomly pick numbers from the persons lists and make those 5 as a list and insert them into the teams list after inserting them into the teams list I need to remove those numbers from the persons list as there might be a chance a single number enters into 2 teams.

To do so we need random package. here's the code

# Repeat the process until there are less than 5 members left
while len(persons)>5:
        # picks 5 random numbers from persons list
        a = sample(persons,5)
        # add the list of numbers as a single team
        teams.append(a)
        # after adding remove them to avoid redundancy
        for i in a:
            persons.remove(i)

That's it! now we got our required teams in the teams list

Full code

import csv
from random import sample
persons = []
teams = []
with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for i in reader:
        persons.append(i[0])
    while len(persons)>5:
        a = sample(persons,5)
        teams.append(a)
        for i in a:
            persons.remove(i)
    for i in teams:
        print(i)
    print(persons)
