How do I set up a server-side proxy?

To set up a server-side proxy, you'll need to choose a server technology, like Node.js or Python. Do you have a preference?

I prefer using Node.js. What are the steps?

Great choice! First, install the necessary packages like 'http-proxy' using npm. Then, create a basic server that listens for requests.

Can you provide a sample code for that?

Sure! Here's a simple example:

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

const proxy = httpProxy.createProxyServer();

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

server.listen(3000, () => {
  console.log('Proxy server is running on http://localhost:3000');
});

What if I want to handle errors?

You can add an error handler like this:

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