Real-time GraphQL API in Elixir & Phoenix

Why take this course?
🌟 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:
-
User Authentication:
- Secure user registration and login mechanisms.
- Session management for logged-in users.
- Fetching authenticated user details.
- Graceful logout process.
-
Room Management:
- Dynamic room creation and listing.
- Efficient deletion of rooms along with their messages.
-
Messaging System:

- Real-time message subscription via websockets.
-
Pagination:
- Implementing cursor-based pagination to handle large datasets efficiently.
-
Protected Routes:
- Enforcing access control for routes to protect sensitive operations from unauthorized access.
-
Testing with Tools:
- Hands-on experience with Insomnia and GraphQL Playground for API testing and validation.
-
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.
