I want to create a Node Red project with basically the following features:
- Users can log in via web page. The users have different roles.
- Some roles enter data which is stored on a database or other item on the Raspberry Pi
- Some roles only show data from a database or other source on the Raspberry Pi
- Whenever one user enters data, the shown data for the other users have to be updated when applicable
I have a rough idea on how I can create a login page. But I don't know an easy way to update data on a web page triggered by the "server" (when data content changes). Any ideas for me, perhaps with examples?
Thank you
