Let's see if we can harmonize the this story with the goals below.

Goal: stable plaform

Definition of done:

Correct placements of components and plug-ins;

Components should in OSCD/components

Plug-ins should be packages/plug-ins/

no more flake tests

When we migrate plug-ins into their own plug-ins directory; we can to make sure that the test in that plug-in that the assertions on doc modifications are correct (use code coverage?)

80% test coverage for plug-ins

Prettify project / ESlint should be part of the pre-commit-hook; Use the Airbnb rules (ESlint config)

Exclude: end to end test

TODO;

• Move addons into @openscd/open-scd/package/addons
• Extract types and interfaces to core #1476
• Move components out of packages/open-scd
• Standardize ESlint config on root level using Airbnb rules

Example ESlint config
Add @nx/eslint * global .eslint rules
