WebSocket Initiation curriculum: 5 modules over 5 days
Module 1 : WebSocket Fundamentals: Principles and Installation (Node.js tools, editors)
Dive into the basics of WebSockets, differentiate them from HTTP polling, install Node.js, npm, and VS Code, perform your first client-server handshake through interactive exercises, analyze network frames with DevTools, create a simple echo to validate your skills, and experience the magic of real-time from day one.

Master the native WebSocket API in JavaScript, code a client connected to a test server, manage open, message, close, and error events, integrate send/receive buttons into an HTML page, test with concrete cases like a live counter, export your functional client, and gain application fluidity.
Module 3 : WebSocket Server: Node.js and Socket.io (Connection Management)
Build a robust server with Node.js and Express, add Socket.io for simplicity, manage rooms and namespaces, implement broadcast and targeted messages through basic chat exercises, simulate 50 simultaneous connections, debug with advanced logs, deploy locally, and thrill with live multi-user interactions.
Module 4 : Advanced Management: Authentication, Reconnection (JWT, Heartbeats)
Secure your WebSockets with JWT for authentication, implement heartbeats to detect disconnections, code resilient automatic reconnection, handle errors and structured JSON payloads, apply to a live dashboard with updating charts, test under load with tools like Artillery, and refine your skills for reliable apps.
Module 5 : Final Project and Integration: Complete Real-Time Application
Synthesize everything in a capstone project like a collaborative chat or live notifier, integrate WebSocket with React or Vanilla JS, deploy on free Heroku, optimize performance and security, present your deliverable to the group, receive expert feedback, and leave with a concrete portfolio and confidence to boost your innovative web projects.
