Real-time GraphQL API in Elixir & Phoenix

🌟 Course Title: Real-time GraphQL API in Elixir & Phoenix

Dive into the Functional Programming Realm with Elixir!

🎓 Course Instructor: Aman Bhardwaj

Elixir is a dynamic, functional language designed for building scalable and maintainable applications. It leverages the Erlang VM, known for running low-latency, distributed systems such as WhatsApp, Discord, and Pinterest. In this course, we will harness the power of Elixir along with its companion framework, Phoenix, to create a real-time GraphQL API from scratch.

What You'll Learn:

🚀 Course Description:

• Understanding the Basics: We'll kick off by getting familiar with the fundamental concepts of Elixir and how it handles concurrency and fault tolerance, which are key to building robust applications.

• Phoenix Framework Mastery: Dive into the Phoenix Framework, which simplifies web application development in Elixir. Think of it as the Express.js of Node.js but with a functional twist that makes it even more powerful and exciting.

Course Architecture Overview:

• User Authentication:

  • Register User
  • Login & Session Management
  • Get Authenticated User
  • Logout

• Room Management:

  • Create Rooms
  • List All Rooms
  • Delete Room and its Messages

• Messaging Functionality:

  • Post Messages to a Particular Room (with persistence to the database)
  • Subscribe to a Particular Room for Real-Time Notifications

Advanced Features & Concepts:

• Pagination: Implement cursor-based pagination to efficiently fetch messages without overwhelming clients with thousands of records.

• Protected Routes: Enforce access control lists (ACLs) to ensure that only authenticated users can create rooms or post messages.

Testing and Tools:

• API Testing: Use Insomnia and GraphQL Playground to test your API endpoints as you develop each route, ensuring a robust and responsive API from the ground up.

• Learning Beyond the Basics: As we delve deeper into Elixir, Phoenix, and GraphQL, you'll learn a wealth of knowledge that goes far beyond the scope of this course. The skills you acquire here will be applicable to a multitude of real-world scenarios.

What's Covered in Detail:

1. User Authentication:

   • Secure user registration and login mechanisms.
   • Session management for logged-in users.
   • Fetching authenticated user details.
   • Graceful logout process.

2. Room Management:

   • Dynamic room creation and listing.
   • Efficient deletion of rooms along with their messages.

3. Messaging System:

   • Sending messages to specific rooms (with database persistence).
   • Real-time message subscription via websockets.

4. Pagination:

   • Implementing cursor-based pagination to handle large datasets efficiently.

5. Protected Routes:

   • Enforcing access control for routes to protect sensitive operations from unauthorized access.

6. Testing with Tools:

   • Hands-on experience with Insomnia and GraphQL Playground for API testing and validation.

7. And Much More:

   • As you progress through the course, you'll gain a deep understanding of Elixir, Phoenix, and GraphQL, along with best practices for building real-time APIs.
