Creating an HTTP Proxy Server

This code sample demonstrates how to create a basic HTTP proxy server that forwards incoming requests to 'http://example.com'. It showcases the use of the 'createProxyServer' method to create a proxy instance and the 'web' method to proxy HTTP requests.

import * as http from 'http';
import * as httpProxy from 'http-proxy';

const proxy = httpProxy.createProxyServer({});
const server = http.createServer(function(req, res) {
  proxy.web(req, res, { target: 'http://example.com' });
});

server.listen(8000);

Listening for Proxy Events

This code sample shows how to listen for errors on the proxy server. When an error occurs, it sends a 500 response to the client with a message indicating that something went wrong. This is useful for handling and logging errors.

proxy.on('error', function (err, req, res) {
  res.writeHead(500, {
    'Content-Type': 'text/plain'
  });
  res.end('Something went wrong.');
});
