Nodejs: pass variable from url to other files and update mongodb


An example URL in the browser: https://www.thistestdomaindoesnotexist.com/?wmid=232416


I want to pass one variable from a url string to other files inside the script
and later when user signup on register-form.tsx, the variable should be written
into the mongodb collection users.


My idea:


yarn add express
yarn add cors



var express = require('express');
var app = express();

app.get('/', function(req, res){
res.send('wmid: ' + req.query.wmid);
});



For adding the value in mongodb some backend files must be changed.
(I added some backend api files)


Frontend files:

The first site that is opened:
login-form.tsx

User can click registration and goes to:
register-form.tsx

So the variable should pass the first site and on register-form.tsx there is a user registration form
and the value wmid must be written to the mongodb.


//I can yarn build and test it: db["users"].find()


Should be an easy task for nodejs developer.
