And this completes my "homework project" for the excellent Oracle JET online course:
Soar higher with Oracle JavaScript Extension Toolkit (JET)
I strongly recommend this Oracle JET course for anyone interested in custom web development.
The code I shared could be optimized, or course, and a lot of vars could be moved to a JSON config file, etc; but this project was a good way to learn Oracle JET basics, and the dashboard is useful and works.
Additional indicators and modules can easily be added as required; and we are only scratching the surface of Oracle JET in this simple example.
