feat(ivy): Support resource resolution in JIT mode.

Used to resolve resource URLs on @Component when used with JIT compilation.

@Component({
  selector: 'my-comp',
  templateUrl: 'my-comp.html', // This requires asynchronous resolution
})
class MyComponnent{
}

// Calling `renderComponent` will fail because `MyComponent`'s `@Compenent.templateUrl`
// needs to be resolved because `renderComponent` is synchronous process.
// renderComponent(MyComponent);

// Calling `resolveComponentResources` will resolve `@Compenent.templateUrl` into
// `@Compenent.template`, which would allow `renderComponent` to proceed in synchronous manner.
// Use browser's `fetch` function as the default resource resolution strategy.
resolveComponentResources(fetch).then(() => {
  // After resolution all URLs have been converted into strings.
  renderComponent(MyComponent);
});

Any reason not to use Angular's own HTTP implementation by default?

Toxicable · 2018-06-24T22:41:36Z

@alfaproject That would mean that Core would depend on Common already depends on Core, this would be a cyclic dependancy.

Otherwise LGTM

Angular does not currently have a dependency on fetch, even via typings. It's not supported, for example, in IE < Edge.

What about removing Response from our public API typings and instead using the signature: (url: string) => Promise<string | { text(): Promise<string> }>. This fits fetch() without introducing a dependency on DOM typings.

Also, Promise<void> is the typical way of expressing that a function returns a Promise that has no meaning other than its resolution.

Good idea, done.

I see that you just added the PR action: merge label, but the following checks are still failing:
     missing required status "code-review/pullapprove"
     status "ci/circleci: lint" is pending
     status "ci/circleci: build-packages-dist" is pending
     status "ci/circleci: test_ivy_aot" is pending
     status "google3" is pending
     status "ci/circleci: test_ivy_jit" is pending
     status "ci/circleci: test" is pending
     status "continuous-integration/travis-ci/pr" is pending

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.

This would reorder the styles according to response finish time rather than preserve the declared order, right?

Good catch, fixed and added a test.

P.S.: Do you need await? Thought jasmine supports promises now

FYI Jasmine 2.8 supports this natively

Is the async/await support in jasmine(exposed in this PR) only for the Ivy compiler? Or does this support also apply to the current AOT/JIT compilers? Wasn't sure why this was under the Ivy context.

@dman777 This API change has been reverted yesterday in e1c6fd5 so it doesn't really matter ;)

Oh, the readme for 6.1 shows otherwise. Is the readme in error?

@dman777 Oh man I was worried this ended up in 6.1 for a second. It has been reverted just before 6.1 was cut, so it has NOT been released. The changelog is generated automatically based on the conventional commits format, where apparently the revert commit hasn't cancelled the creation commit. So yes, the changelog is in error.

Ok, thanks for the heads up. I hope this goes back in soon. Now that Jasmine is testing the DOM there can be race conditions that are hard to test for.
