Proxy-nodejs

A proxy in Node.js is an intermediary server that acts as a gateway between clients and servers. It intercepts requests from clients seeking resources from other servers and then forwards these requests to the appropriate server.

Proxy servers have many use cases, including caching responses to improve performance, load balancing requests across multiple servers, and enforcing security and access control policies.

In Node.js, you can create a proxy server using the built-in http or https modules. Here's an example:

const http = require('http');
const httpProxy = require('http-proxy');

const proxy = httpProxy.createProxyServer({});

http.createServer((req, res) => {
  // Forward requests to the target server
  proxy.web(req, res, { target: 'http://localhost:3000' });
}).listen(8080);

console.log('Proxy server running on port 8080');

In this example, we create a proxy server that listens on port 8080 and forwards requests to a target server running on port 3000.

The http-proxy module provides a convenient API for intercepting and forwarding requests, handling errors, and configuring various options such as SSL/TLS, load balancing, and sticky sessions.

Overall, using a proxy server in Node.js can help streamline your application's network traffic, improve performance, and enhance security.
