Date: 2 May 2022 | Posted by: voska89

Dive into the functional programming realm with none other than Elixir, the stack which powers Whatsapp, Discord etc
What you'll learn
Create fully featured GraphQL API in Elixir & Phoenix
Learn to implement authentication,, authorization, Queries, Mutations, Subscriptions in the realm of pure functional programming language Elixir.
Queries, Mutations, Subscriptions? You name it we have it.
Dive into the tech stack which powers our very own WhatsApp, Discord, Pinterest and alike.
Requirements
Basic knowledge of Elixir, Phoenix and GraphQL is required. A Todo list experience in these technologies would be more than sufficient.
Description
Create GraphQL API in Elixir. The language which powers, in one way or another (ErLang) Whatsapp, Discord, Pinterest etc.
We will be using Phoenix Framework, the fantastic MVC framework for developing backends and full stack projects in Elixir. Consider Phoenix more like Express of Node.js but way more cooler of course. Well, Elixir altogether is cooler than any other language I code but nevertheless, one thing at a time.
Architecture
Users
Register User
Login
Get Authenticated User
Logout
Rooms
Create Rooms
Get All Rooms
Delete Room and all of it's messages
Messages
Post Messages (persisted to db) to a particular room.
Subscribe to a particular room to get the newly posted message notifications in real time.
Pagination
Cursor Based Pagination for fetching messages so that we don't give back all the messages of a room at once (which could be of thousands of number as you can imagine).
Protected Routes
Implement private routes to maintain an access control list => what can be accessed and what not. For example, a non authenticated user (guest) should not have access to the following apis
Create Room
Post Message to a Room
etc...
Insomnia & GraphQL Playground
Test the API with Insomnia & GraphQL Playground (For testing Subscriptions), along the way, while developing each route.
A lot more
We will be learning a lot more than written, about Elixir, Phoenix GraphQL, and creating APIs altogether
Who this course is for
Amateur Elixir Developers and functional programming & GraphQL enthusiasts
