Hi @fredabod , nice introduction to this topic.

Pointing out improvement points:

Assuming that the headers look like that:

Authorization: {
    token: 'myToken'
}
Enter fullscreen mode Exit fullscreen mode

I'd change

const token = req.headers.authorization.split(' ')[1];
Enter fullscreen mode Exit fullscreen mode

for

const { token } = req.headers.authorization;
Enter fullscreen mode Exit fullscreen mode

just to avoid runtime errors if something went wrong (e.g. Authorization being undefined) as well as for maintainability as you can know what it does by just reading at this while in the array hardcoded position implementation you can be wondering "what the heck does Authorization have?".

Also take a look at CORS and specially to the DB Salt concept so you get better security on this.

Hope it helps somehow, best regards ๐Ÿ˜
