I Built My First Template!

Desmond — Sat, 06 Nov 2021 23:49:50 +0000

Hello Dev Community!👋🏽
It's been over a year since I posted here but it's high time I joined the community once again!

I'm committing to developing HTML and React themes every month. To kickstart that, I developed my first HTML Template which can be purchased on Gumroad with the link below. This template was built solely with HTML, CSS (TailwindCSS) and some JavaScript.

Here are some beautiful shots of my theme:

Build A Complete Solution With Django and React

Desmond — Sat, 04 Jul 2020 17:03:00 +0000

I've been postponing this for so long ( Sharing the repository), but I've decided to finally share with those interested in contributing. I've been waiting till I "document" it but that never happened.

Python 3.9

Desmond — Fri, 19 Jun 2020 13:30:32 +0000

Python 3.9 🥳 is out and my favourite feature is the dictionary union operator.

Example


a = {1: 'dog', 2: 'cat', 3: 'rabbit'}
b = {4: 'snake', 5: 'python'}
c = a | b
print(c)

# {1: 'dog', 2: 'cat', 3: 'rabbit', 4: 'snake', 5: 'python'}

Build a complete warehouse management system with React and Django.

Desmond — Tue, 09 Jun 2020 08:13:15 +0000

Update

My React Frontend now authenticates successfully with my django backend through Token Authentication. Might change it to JWT's later on.
My only doubt is whether to continue storing the Token in localstorage in the screenshot below(Might be a vulnerability) or request the token on every request to the backend (Delayed responses due to two round trips?). Please comment below with your views .

Caching
Added A Caching layer as well with Redis. It only caches a section of the template rendered by homepage and some other read heavy pages.
This is built into django with the help of the caching templatetags.

#view
from django.views.decorators.cache import cache_page

@cache_page(60 * 15)
def my_view(request):
    ...

 #template file
{% load cache %}
  {% cache menu request.user.email %}

 #menu for logged in user

{% endcache %}

Build a warehouse management solution with react, django, react-native and AWS.

Desmond — Tue, 26 May 2020 20:30:46 +0000

Update on the project.

I worked on the list views today.
All Products, Shipments, Customers

Up next I have to work on Authentication from the frontend. My Django Backend already exposes a route '/api-auth' which uses basic authentication as it's authentication scheme.

Build a warehouse management solution with react, django, react-native and AWS.

Today I worked on token authentication for my Backend.Now my frontend would need a username and password to create a token which would be stored in localstorage for every subsequent request made to my django backend

Token would be sent to backend like this;

"Token /auth_token/"

Build a Complete Solution With AWS, Django , React , React Native and Heroku - Day 2

Desmond — Sun, 17 May 2020 14:41:25 +0000

Today I got the List api endpoints from the django backend working

Root API endpoint = /api/v1

Products = /products/all
Warehouses = /warehouses/all
Customers = /customers/all
Shipments = /shipments/all

To enable My React work with my backend I needed to install django-cors-headers and add localhost:300 to my whitelist.This is as a result of CORS

Cross-origin resource sharing is a mechanism that allows restricted resources on a web page to be requested from another domain outside the domain from which the first resource was served.

The next thing I need to do is to work on all my components in React.

Build a Complete Solution with Django,React, React Native, AWS, Heroku

Desmond — Sat, 16 May 2020 15:12:27 +0000

Hey guys,
It has got to the point where I have a good number of technologies I can work with comfortably but I feel like having to make all of this work together and deploying them when they're tied together is something I haven't done.

So here's the plan,
I have already built out a simple warehouse management solution in django.
In the next few weeks,

I'll be working on a react frontend which means I have to build out an api with django rest framework* for the already built out backend.
Build a React Native client
Deploy django backend on Heroku and react frontend on S3

Extra perks

Add Graphql
Add a caching layer with Redis

Here's a preview of the UI

Let's do this!
I'll add a link to my repository in the next one.

An Introduction to Remote Procedure Calls (RPC's)

Desmond — Fri, 15 May 2020 12:30:20 +0000

I've started studying distributed systems in college and here's a beginners view on RPC's.

What is a Remote Procedure call?

Remote Procedure calls are protocols that enable a program execute a service in a different address space or another computer for simplicity.These are normally referred to as subroutine calls or function calls.

RPC's are synchronous which means client programs requesting need to be suspended until the results of the subroutine call is returned.

In the OSI model, an RPC laps the transport layer and Application Layer.

Types of RPC

The regular method in which the client continually pings the server until it responds.
The client requests and continues to process without having to wait for a response from the server. note : The server doesn't respond.
Sending non-blocking client calls in bulk.
Sending messages to many servers and receiving replies
Client makes a non-blocking client/server call , the server responds by invoking a procedure associated with the client.

Mini Search Platform For Covid-19

Desmond — Wed, 01 Apr 2020 08:03:37 +0000

I built this platform to help you find updated information on the numbers if cases in every country worldwide.
CoronaSite.

I built it in a rush and didn't follow the DRY principle , I plan on fixing that soon.

Please suggest changes or new features..
