Chaptet 8 - Single-Origin, Multi-Route Proxy, Invalid URL
I followed the code in the course and updated my app.js
too look like this
'use strict' const proxy = require('fastify-http-proxy') module.exports = async function (fastify, opts) { fastify.register(proxy, { upstream: 'https://news.ycombinator.com/' }) }
after running the app, I got this error.
TypeError [ERR_INVALID_URL]: Invalid URL: https://news.ycombinator.com/
[fastify-cli] app crashed - waiting for file changes before starting..
any solutions for this one?

@reuben158 you've somehow included an invisible zero width non-joiner character, just before the "p" in https, which makes the url invalid.

@reuben158 did you get this error in WSL as well?

"use strict"; const path = require("path"); const AutoLoad = require("fastify-autoload"); module.exports = async function (fastify, opts) { // Place here your custom code! fastify.register(require("fastify-http-proxy"), { upstream: "https://news.ycombinator.com/", }); // Do not touch the following lines // This loads all plugins defined in plugins // those should be support plugins that are reused // through your application fastify.register(AutoLoad, { dir: path.join(__dirname, "plugins"), options: Object.assign({}, opts), }); // This loads all plugins defined in routes // define your routes in one of these fastify.register(AutoLoad, { dir: path.join(__dirname, "routes"), options: Object.assign({}, opts), }); };
With fastify 3.x.x this code above is generated. Paste the custom code and delete the root.js (or uncomment or change the endpoint, whatever...)

https://en.wikipedia.org/wiki/Zero-width_non-joinerI got the same issue and is when we copied the code from that page (Single-Origin, Multi-Route Proxy (1)), VsCode told me "The character U+200c is invisible."

With the same code right now we got an error
FastifyWarning.fastify-http-proxy: fastify-http-proxy has been deprecated.
, because of the new fastify version.to solve that please instead use
npm i @fastify/http-proxy
and in root:'use strict' const proxy = require('@fastify/http-proxy') module.exports = async function (fastify, opts) { fastify.register(proxy, { upstream: 'https://news.ycombinator.com/' }) }
