Next steps:

  • decide whether to add more type declarations (e.g. for context pad, palette, ...)
  • decide whether or not the strategy for testing the type declarations is sufficient
  • fix JSDoc comments
  • add type declarations to bpmn-js

$inject is necessary? Why?

And if we require it it shall be static.

I was asking myself that question. I'd like to communicate somehow that a command handler is going to be instantiated by the command stack and, therefore, can use the $inject syntax. Unfortunately, interfaces do not support static members (cf. microsoft/TypeScript#13462).

Let's not transport that through types, but through proper documentation.

You could consider to expand the CommandHandler documentation or write new one (docs.bpmn.io).

Really nice stuff.

I dove into this and added #744 as a potential to improve this PR. Please have a 👀.

What I really like is how you created dedicated type specs (that also cover real world use-cases).

This way we can build out types on a real world use-case / demand basis.

Consider splitting up existing type tests so the file does not get HUGE at some point.

@barmac This is not urgent I believe. Please add your feedback, and also account for #744 in the process.

As discussed with @nikku we will:

  • merge Type declarations 2 #744 (review) into the feature branch of this pull request
  • not add more type declarations
  • add integration tests for each type declaration file (e.g. Canvas.spec.ts tests Canvas.d.ts)
  • fix and copy/add JSDoc comments to the type declarations

@nikku I walked @marstamm through the pull request today and he'll review it, too. Yes, I'm making a couple of adjustments that are easy fixes. Let's chat tomorrow.

CoreModule and ModelingModule import the same thing here. Because the test suceeds, I assume we don't actually need the Core Module here?

Ooopsie. Good catch! The tests don't fail because errors due to missing modules can only happen during runtime.

I simplified some import paths and fixed some typos. Can you confirm that #732 was just a copy/paste issue and not something fundamental?

Other than that, I am happy to merge it 🎉
