Login/Authorization System Migration to uWebSockets.js: Cookie Reading Issue

[BroderTheCuriousDev]

Background

I am trying to build a login/authorization system on Uwebsocket. I recently migrated from socket.io and
came to the conclusion that I can not use passport.js anymore. I decided to rewrite the authorization system from scratch.

Challenge

The problem I am encountering is the cookie I set in a .get route can not be read in the ws.upgrade handler.
When trying to use the req.getHeader('cookie') it returns nothing.

I have tried just about everything and read through all the discussions and issues I can find on this Repo but to no avail.

Reference

I stumbled across this answer on a different discussion How to implement user authorization? #112 but this code yields no better results.

Objective

1. Authenticate the user in an HTTP route. Generate JWT token
2. Set the cookie on the user
3. Read the cookie in the WS upgrade handler

Code Example

const {App} = require('uWebSockets.js')

  const app = App()
  app
    .ws('/*', {
      upgrade(res, req, context) {

          const cookies = req.getHeader('cookie') 
          // Implement cookie validation and other logic
  
          console.log(cookies)
  
          res.upgrade(
          {},
          req.getHeader('sec-websocket-key'),
          req.getHeader('sec-websocket-protocol'),
          req.getHeader('sec-websocket-extensions'),
          context
          )
      },
      open(ws) { }
    })
    .any('/*', (res, req) => {
      // Set the cookie 
      res.writeHeader('Set-Cookie', '_token=jwt; SameSite=Strict; HttpOnly') // Only example
      res.end('cookie sample')
    })
    .listen('::', 9001, token => {
      console.info(token)
    })

Any insights or suggestions on overcoming this cookie reading issue would be highly appreciated. Thank you!

You are lacking basic troubleshooting steps. Did you check browser to confirm cookie was set, and was sent with request via chrome dev tools ?

Your exact example code works fine, did you try your example or you copy/pasted select parts of your app and did not try it ?

Hey. I did in fact try it. After getting your confirmation that the code does indeed work I started to look at external factors. I was using live-server to host my temporary index.html file which opened a server at 127.0.0.1 instead of localhost. This is something I missed in the heat of the moment. I thought I was missing something related to Uwebsocket.js. Thank you for pointing me in the right direction!
