Problem since TypeScript 2.7.1 – Type 'M[keyof M]' does not satisfy the constraint 'EventObject<keyof M>'

[inad9300]

I have a dependency on @dojo/loader version 0.1.1 for testing (I'm using the Intern framework and this seems to be required for some use case). After upgrading to TypeScript 2.7.1 (from 2.6.2), I started to see this exceptions coming from @dojo/core:

node_modules/@dojo/core/Evented.d.ts(32,95): error TS2344: Type 'M[keyof M]' does not satisfy the constraint 'EventObject<keyof M>'.
node_modules/@dojo/core/Evented.d.ts(58,72): error TS2344: Type 'M[K]' does not satisfy the constraint 'EventObject<K>'

This happens when I run intern, but seems to be related with Dojo alone.

Currently Dojo 2 packages only support up to typescript ~2.6.2

Any plan to fix that in the near future?

It’s an enhancement and it’s on the roadmap but it’s unlikely to be before release candidate and release.

@inad9300 To be clear, the first release candidate for Dojo 2 is due this week, and the release shortly thereafter (probably 2 more weeks?), and then as soon as 2.0 ships, one of the first items on our list is to update to TS 2.7. So it depends on your definition of near future being 1 week (no) or 1 month (most likely).

Is a release including this merge scheduled? Thank you!

[agubler]

Hey @inad9300, @dojo/core has been released with these changes on 0.5.0.

[inad9300]

My question is about @dojo/loader. (Edit Which I guess depends on @dojo/core.)

[agubler]

@inad9300 dojo/loader does not depend on dojo/core

[inad9300]

OK, I see it is Intern which is depending on it, which still uses version 0.3.0. Thanks for the update, I'll see with them.
