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

1. Users

   1. Register User

   2. Login

   3. Get Authenticated User

   4. Logout

2. Rooms

   1. Create Rooms

   2. Get All Rooms

   3. Delete Room and all of it's messages

3. Messages

   1. Post Messages (persisted to db) to a particular room.

   2. Subscribe to a particular room to get the newly posted message notifications in real time.

4. Pagination

   1. 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).

5. Protected Routes

   1. 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

      1. Create Room

      2. Post Message to a Room

      3. etc...

6. Insomnia & GraphQL Playground

   1. Test the API with Insomnia & GraphQL Playground (For testing Subscriptions), along the way, while developing each route.

7. A lot more

   1. We will be learning a lot more than written, about Elixir, Phoenix, GraphQL, and creating APIs altogether.
