I recently had to implement a bearer token authentication mechanism in a Spring backend and an Angular frontend. I wasn’t surprised to see that there are already a lot of tutorials around, however, I was shocked by how poorly most of them are written and how bad some solutions were.

However, this has worked for me and I think it’s much easier to understand and follow than other guides. Additionally, there are a few things that almost all tutorials get wrong and I’ll try to address these as well.

For a current project of mine, I had to evaluate how high the latency is when using websockets. In my case, I wanted to use a small single board computer as the server and any device, that can run a web browser, as the client. This tutorial illustrates how a Raspberry Pi and an ESP8266 can be used to act as a websocket server that can be controlled with a standard webbrowser.
