WebSocket Examples

This folder contains examples of real-time web applications built using WebSockets with Node.js and Express.js. These examples demonstrate how to implement real-time communication between the server and clients.

Examples

1. Real-Time Notifications

• Description: A web app that sends real-time notifications to connected clients. Notifications are triggered by server-side events and displayed instantly on the client.
• How to Run:
  1. Navigate to the real-time-notifications folder.
  2. Install dependencies:

     npm install

  3. Start the server:

     node index.js

  4. Open your browser and navigate to http://localhost:3000.

2. Stock Tracker

• Description: A web app that tracks stock prices in real-time. The server sends updated stock prices to all connected clients, and the data is displayed dynamically on the client.
• How to Run:
  1. Navigate to the stock-tracker folder.
  2. Install dependencies:

     npm install

  3. Start the server:

     node index.js

  4. Open your browser and navigate to http://localhost:3000.

Prerequisites

• Node.js installed on your machine.

Notes

• Each example uses WebSockets for real-time communication.
• Static assets (e.g., JavaScript, CSS) are located in the public folder of each app.
• View templates are located in the views folder of each app.
• These examples are for demonstration purposes and do not include advanced features like authentication or persistent storage.
