I'm currently preparing a set of Node-RED flows and use cases for my students in order to motivate and encourage them to invent and build web sites and REST services without having to know, learn and program much.
As part of that set I've just published a few examples for simple REST services on GitHub.
These services include three examples for Key-Value Stores and a service for simple file management from remote.
Since they may also be of interest to others, feel free to use them in whatever way you like.
As usual, any feedback is welcome!
With greetings from Germany,
