Question

I feel like pulling my hair out; this is either super simple and i\'m having brain freeze or it is not that simple.

First make sure you are receiving the request properly with the shortened url.

const functions = require('firebase-functions');

const express = require('express');
var express_app = express();
express_app.use(body_parser.text({type: ()=>true}));
express_app.all('*', (req, res) => {
    console.log(req.path);
    res.send(JSON.stringify(req.path));
});
exports.url = functions.https.onRequest(express_app);

Now when you visit myapp.firebaseappurl.com/url/SHORTENEDLINK you should see the SHORTENEDLINK in plain text. When that's working, try the redirect.

const functions = require('firebase-functions');
const express = require('express');
const request = require('request');
var express_app = express();
express_app.use(body_parser.text({type: ()=>true}));
express_app.all('*', (req, res) => {
    var url = req.path;
    request({
        uri: uri,
        followRedirect: true
      },
      function(err, httpResponse) {
        if (err) {
          return console.error(err);
        }
        res.send(httpResponse.headers.location || uri);
      }
    );
});
exports.url = functions.https.onRequest(express_app);

Also it's good practice to npm install with --save so they end up in the packages.json. While firebase copies your node_modules folder, most other SaaS platforms run npm install.
