Interesting lesson but a little more practical context for the project built in the lesson would have been better. Such as: We are building this API that is delivering jokes or something like that. This API will be consumed by other APIs, therefore we use oauth2-server to make a client credentials grant flow for our customers (other developers connecting to the API). That would have been helpful to better understand where this library/technique is the right tool for the job. Perhaps the last demo of the functionality can even include 2 servers - the one we build with oauth2-server and another one (with a UI) that gains access to the API after client secret is entered and gets some data.
