Victor Berchet 0ebd577db4 refactor(compiler): Drop support for the deprecated `<template>`. Use `<ng-template>` instead (#22783)
BREAKING CHANGE:

The `<template>` tag was deprecated in Angular v4 to avoid collisions (i.e. when
using Web Components).

This commit removes support for `<template>`. `<ng-template>` should be used
instead.

BEFORE:

    <!-- html template -->
    <template>some template content</template>

    # tsconfig.json
    {
      # ...
      "angularCompilerOptions": {
        # ...
        # This option is no more supported and will have no effect
        "enableLegacyTemplate": [true|false]
      }
    }

AFTER:

    <!-- html template -->
    <ng-template>some template content</ng-template>

Angular Package Format v6 stops bundling files in the esm5 and esm2015

Alex Rickabaugh 6e00410e1c fix(compiler-cli): annotate Ivy fields as @nocollapse in closure mode (#22691)
Closure has a transformation which turns:

Service.ngInjectableDef = ...;

into:

Service$ngInjectableDef = ...;

This transformation obviously breaks Ivy in a major way. The solution is
to annotate the fields as @nocollapse. However, Typescript appears to ignore
synthetic comments added to a node during a transformation, so the "right"
way to add these comments doesn't work.

As an interim measure, a post-processing step just before the compiled JS is
written to disk appends the correct comments with a regular expression.

Igor Minar 3f70aba272 fix(compiler-cli): disableTypeScriptVersionCheck should be applied even for older tsc versions (#22669)
Previously the flag would only disable the check in the case we tried to use newer tsc version.

In g3 we sometimes take a while to update tsc, but as a prerequisite of that Angular needs to be
updated first. This change enables us to update Angular and use it in g3 while g3 is being update
to the required tsc. Of course extra care is required when this check is disabled, but since we
control everything in g3, it's on us to get this right.

I don't see any preexisting tests for this, and I'm not sure how to write them right now.

Hans Larsen 288851c41e release: add ng update package group metadata to angular (#22482)
"ng update" supports having multiple packages as part of a group which should be updated together, meaning that e.g. calling "ng update @angular/core" would be equivalent to updating all packages of the group (that are part of the package.json already).

In order to support the grouping feature, the package.json of the version the user is updating to needs to include an "ng-update" key that points to this metadata.

The entire specification for the update workflow can be found here: 2e8b12a4ef/docs/specifications/update.md

inject() supports the ngInjectableDef-based configuration of the injector
(otherwise known as tree-shakeable services). It was missing from the
exported API of @angular/core, this PR adds it.

InjectionToken can be created with an ngInjectableDef, and previously
this allowed the full expressiveness of @Injectable. However, this

Alex Rickabaugh 7ac34e42a0 feat: allow direct scoping of @Injectables to the root injector (#22185)
@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs
in the root injector. A developer attempting to ensure that must either
also provide a module intended for placement in the root injector or target
a module known to already be in the root injector (e.g. BrowserModule).
Both of these strategies are cumbersome and brittle.

Instead, this commit adds a token APP_ROOT_SCOPE which provides a
straightforward way of targeting the root injector directly, without
requiring special knowledge of modules within it.

Alex Rickabaugh 235a235fab feat: change @Injectable() to support tree-shakeable tokens (#22005)
This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.

Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".

Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.

Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.

Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

Chuck Jazdzewski e7d9cb3e4c feat(compiler): narrow types of expressions used in *ngIf (#20702)
Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.

NgIf was modified to declare an input guard on ngIf.

After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.

For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.

The template compiler will generate code similar to,

```
  if (NgIf.ngIfTypeGuard(instance.person)) {
    instance.person.name
  }
```

to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.
