Response Compression Middleware

The compressResponse middleware compresses the response body using Gzip compression if the client supports it.

Parameters

• req: The request object.
• res: The response object.
• next: The next middleware function in the request-response cycle.

Description

The compressResponse middleware checks if the client accepts Gzip encoding. If accepted, it sets the Content-Encoding header to gzip and compresses the response body using Gzip compression.

Example Usage

const express = require('express');
const { compressResponse } = require('apiutils.js');
 
const app = express();
 
// Middleware to compress response
app.use(compressResponse);
 
// Your routes and application logic here...
 
app.listen(3000, () => {
  console.log('Server running on port 3000');
});

Notes

• Ensure to place the compressResponse middleware before your route handlers to compress outgoing responses.
• Gzip compression can significantly reduce the size of the response body, improving network performance and reducing bandwidth usage for clients that support it.
