Hello and welcome to the forum :grin:!

Please, provide the code that you’ve written so far so we can help you, otherwise we cannot know what the problem is :slight_smile:.

Use and/or If using glitch, remember to share the Code view instead of the Project or Live App.

The problem is that you’re not selecting a database, hence the routes fail. Please, always check the glitch console logs to see if there are errors, try to solve them and if you still need help, come to the forum :slight_smile:, that way you’ll learn more.


Replace db.collection with db.db("database_name").collection:

// This is part of the code:
db.db("testdb").collection('users').findOne({ username: req.body.username }, function (err, user) {
// Here goes the rest of the code

db_name is the name of the database you’ve setup on the mongodb atlas or mlab.
