fix(ngClass,ngStyle): support proper API usages and ChangeDetectionStrategy.OnPush strategies #228

ThomasBurleson · 2017-03-19T15:24:26Z

fix(ngClass): properly differentiate between ngClass and class api usages
- class.<xxx> are destructive overrides (as seen in NgClass::klass)
- ngClass.<xxx> use iterables to merge/enable/disable 0...n classes
fix(ngClass,ngStyle): support ChangeDetectionStrategy.OnPush
- Add support for both OnPush change detection strategies and for @input changes.

@see https://plnkr.co/edit/jCICQ1GXFnzFqFTFlXwh?p=preview

fixes #206, fixes #215.

You can collapse short description blocks into a single line:

cssClass would be a lot more descriptive than klazz

This is a similar convention used by NgClass:

@jelbourn - comments addressed. Ready for presubmit.

@jelbourn - I will remove support for class.<xxx> and style.<xxx> responsive APIs and require developers to use ngClass.<xxx> and ngStyle.<xxx> APIs.

ThomasBurleson · 2017-03-27T21:14:27Z

@jelbourn - ready for review and presubmit. All tests pass.

Current tests include cloned copies of those from the Angular core ng-class-spec.ts tests.

Is lt-xs a real thing? I think this should be lt-xl

this seems pointless? just use _mqActivation below

this is a short-cut reference to keep the code clean.

Just want to double check, this is really what you want right? I see klazz, clazz and klass at various points in the code. Also future work: we should make this consistent everywhere, I vote for cssClass

angular ng-class.ts uses klass. Since they already set a precedent, why not be consistent?

Ok but is this the correct one? because I do see all three of these in the code. More important than what we decide to call it is that it be consistent within our code instead of having 3 different variants. But I don't think we necessarily have to follow the same naming conventions for internal variables as them, this is a totally separate repo.

Oh ok I see this is referencing the one from angular core, no issue for this PR then, just the naming thing to consider in the future

should this be lt-xl?

lt-xl, lt-lg, lt-md,lt-sm are all valid responsive aliases.

I see... the Inputs are not entirely correct. I will fix.
