Node forward path request to another server

Question

Currently have a website running a node server that handles all requests for example.com and I created a completely separate wordpress blog on a separate server (running apache) that I would like served on a path like example.com/blog at 172.23.23.23 IP address. The wordpress server doesn't share any code or is even aware of the existence of anything besides itself

What is the best way in node/express to forward all requests in this manner? Also what should the A/CNAME records for the new wordpress server point to?

Interesting I didn't know that existed, but not really what I'm looking for. — Maruf, Jun 12 '15 at 11:29

This works: here's what you need to put in your node app:

var express = require('express');
var app = module.exports = express();

var proxy = require('http-proxy').createProxyServer({
    host: 'http://your_blog.com',
    // port: 80
});
app.use('/blog', function(req, res, next) {
    proxy.web(req, res, {
        target: 'http://your_blog.com'
    }, next);
});

app.listen(80, function(){
    console.log('Listening!');
});

Then in your wordpress app you need to set the Site URL to http://your_node_app.com/blog

Note: You probably already have an express app with probably a body-parser middleware which causes errors and generally doesn't play well with POST requests in http-proxy

You'll find couple solutions in those threads, namely 1: just put this proxy before body-parser, or 2: use connect-restreamer

using your, @laggingreflex, suggestion, I have this question: https://stackoverflow.com/questions/55736094/node-js-proxy-unable-to-load-first-certificate — richardwhitney, Apr 17 '19 at 21:35

Worked and Tested

const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
const app = express();
app.use('*', createProxyMiddleware({target: 'https://yourdomain.com', changeOrigin: true}));
app.listen(3000);

Install the following first

npm i -s express
npm i -s http-proxy-middleware
