A lightweight Node.js HTTP server that serves static web pages with built-in event logging and error tracking capabilities.

• HTTP Server: Built with Node.js native http module
• Static File Serving: Serves HTML, CSS, images, and JSON files
• Event Logging: Advanced logging system with timestamps and unique IDs
• Error Tracking: Automatic error logging to separate log files
• Multi-route Support: Handle different URL routes and serve appropriate content
• Content Type Detection: Automatic content-type handling for different file types
• Development Mode: Hot reload support with Nodemon

• Node.js: JavaScript runtime environment
• Built-in Modules: http, fs, path, events
• date-fns (^4.1.0): Date formatting and manipulation
• uuid (^11.0.4): Unique identifier generation
• Nodemon (^3.1.9): Development server with auto-reload

• Node.js (v14 or higher)
• npm (comes with Node.js)

1. Clone the Repository

   git clone https://github.com/supritR21/WebServer.git
   cd WebServer

2. Install Dependencies

   npm install

npm run dev

Uses Nodemon to automatically restart the server on file changes.

npm start

Runs the server directly with Node.js.

PORT=5000 npm start

Default port is 3500.

Once the server is running, access it in your browser:

• Home Page: http://localhost:3500/
• Greeting Page: http://localhost:3500/greeting.html
• Another Page: http://localhost:3500/new-page.html
• API Endpoint: http://localhost:3500/api/data (if configured)

The server uses URL routing to serve different files:

• Maps request URLs to corresponding file paths in the views/ directory
• Returns 200 status for found files, 400 for 404.html
• Serves images and binary files without UTF-8 encoding

The logging system (logEvents.js) provides:

• Timestamps: Formatted using date-fns (yyyyMMdd HH:mm:ss format)
• Unique IDs: Generated using uuid v4
• Error Logging: Automatically logs errors to errLog.txt
• Custom Logs: Can emit custom log events

Log message content

Events are emitted using Node.js EventEmitter:

myEmitter.on("log", (msg, fileName) => logEvents(msg, fileName));

Edit server.js to add new routes:

case '/your-route':
    // Handle the route
    break;

The server automatically determines content type based on file extension:

• .html → text/html
• .json → application/json
• .css → text/css
• Images → appropriate image types

• 404 Errors: Automatically served with 400 status code
• Server Errors: Logged to logs/errLog.txt with timestamp and error details
• Missing Files: Returns 500 status with empty response

Log files are stored in the logs/ directory and automatically created as needed:

• errLog.txt - Server errors and exceptions
• Custom log files as created by event listeners

1. Make changes to server.js or other files
2. Nodemon automatically detects changes and restarts the server
3. Refresh your browser to see updates
4. Check logs for any errors or events

To deploy this server:

1. Install production dependencies:

   npm install --production

2. Set the PORT environment variable:

   export PORT=3000  # or your desired port

3. Start the server:

   npm start
