Spring – pt 1
Description Spring (Boot) is a Framwork for Java/Kotlin to create Webservers Motivation Caring about the backend, Spring is a convenient way of doing this.

Angular Spring Roundtrip
Goals We want to write something similar to https://boostnote.io with a little bit more sophisticated usecases, let’s see. Usually starting simple and iterating into complexity is a well probed approach. Hints Note for Windows: most of the installs can be done with the tool https://chocolatey.org/install + https://chocolatey.org/packages/ChocolateyGUI which is a handy tool to also keep…
