express-reverse-proxy

The Express reverse proxy I wrote in my YouTube video "How to Fix The Cors Error with a Reverse Proxy"

This is a slightly cleaned up version, so is a little different from the video. As I mentioned, I've refactored the query string code in to its own class and made a couple of other improvements.

Usage:

Clone the repo, then from the terminal, navigate to the project directory and run:

node app.js

You can then access the server on port 3000:

http://localhost:3000

You can map the API you're trying to access by setting API_BASE_URL to the base URL of the API you want to access in your .env file, then making the same call to the proxy server e.g.

Real endpoint: http://a-public-api.com/foo/bar?baz=qux

API_BASE_URL = http://a-public-api.com

You call: http://localhost:3000/foo/bar?baz=qux
