Partytown reverse proxy in NodeJS (Fastify and Next.JS)

🔁 Reverse proxy requests from basic NodeJS server w/ Fastify and Next.JS API handler.

This repo is to show a example of a reverse proxy to use with Partytown.

Running

Fastify

npm install && node fastify-reverse-proxy.mjs

Testing

curl "http://localhost:3000/proxy?target=https://analytics.tiktok.com/i18n/pixel/static/main.MTc5M2Y0YjUwMQ.js"

Should return the text/html from script. Now in the browser, you can test if not will trouble in CORS anymore:

fetch("http://localhost:3000/proxy?target=http://bat.bing.com/bat.js").then((r) => {
  r.text().then((t) => {
    console.log("text retrieved", t);
  });
});

Missing features

1. Return encoded data based on content-encoding Header
2. Return 401 for urls not included in a allow list for proxy
