We now create npm packages to cover all the public api assertions in tools/public_api_guard.
We no longer depend on ts-api-guardian from npm - it is now stale since the repository was archived.
There is no longer a gulp task to enforce or accept the public API, this is in CircleCI as part of running all bazel test targets.

BREAKING CHANGE: after this change, npm and yarn will issue incompatible peerDependencies warning

"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

Previously, when a downgraded component was destroyed in a way that did
not trigger the `$destroy` event on the element (e.g. when a parent
element was removed from the DOM by Angular, not AngularJS), the
`ComponentRef` was not destroyed and unregistered.
This commit fixes it by listening for the `$destroy` event on both the
element and the scope.

The function provided by `ngUpgrade` as `parentBoundTranscludeFn` when
upgrading a component with transclusion, will break in AngularJS v1.5.8+
if no transclusion content is provided. The reason is that AngularJS
will try to destroy the transclusion scope (which would not be needed
any more). But since the transcluded content comes from Angular, not
AngularJS, there is no transclusion scope to destroy.
This commit fixes it by providing a dummy scope object with a no-op
`$destroy()` method.

Previously, having a `=` binding on an upgraded components would result
in setting the corresponding property to an EventEmitter function. This
should only happen for `&` bindings.
This commit rstrores the correct behavior.
Note:
The issue was only present in the dynamic version of `ngUpgrade`. The
static version worked as expected.
The error did not show up in tests, because in AngularJS v1.5.x a
function would be serialized to an empty string in interpolations, thus
making them indistinguishable from uninitialized properties (in the
view). The serialization behavior changed in AngularJS v1.6.x, making
the errors visible.

`packages/upgrade/static/src` is anymlink to `packages/upgrade/src`.
Still, using the correct paths (e.g. using

the same instances.

BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

(#17971)
This commit changes the dynamic version of ngUpgrade to use `UpgradeHelper`,
thus bringing its behavior (wrt upgraded components) much closer to
`upgrade/static`. Fixes/features include:
- Fix template compilation: Now takes place in the correct DOM context, instead
of in a detached node (thus has access to required ancestors etc).
- Fix support for the `$onInit()` lifecycle hook.
- Fix single-slot transclusion (including optional transclusion and fallback
content).
- Add support for multi-slot transclusion (inclusing optional slots and fallback
content).
- Add support for binding required controllers to the directive's controller
(and make the `require` behavior more consistent with AngularJS).
- Add support for pre-/post-linking functions.
(This also ports the fixes from #16627 to the dynamic version.)
Fixes#11044
(#17971)
Although, pre- and post-linking functions are correctly called during directive
linking, directives with `link.post` would throw an error. Interestingly, having
`link.pre` only or defining `link: fn` (which is an alias for `link.post: fn`)
would not throw.
This commit removes this check and allows directives with pre- and/or
post-linking functions to work.
Previously, only simple, single-slot transclusion worked on upgraded components.
This commit fixes/adds support for the following:
- Multi-slot transclusion.
- Using fallback content when no transclusion content is provided.
- Destroy unused scope (when using fallback content).
Fixes#13271
This wraps the $interval service when using upgrade to run the
$interval() call outside the Angular zone. However, the callback is
invoked within the Angular zone, so changes still propagate to
downgraded components.
Use bracket notation to access $inject in downgradeInjectable to
support property renaming. Since the return type is any,
Closure compiler renames $inject.

Previously, non-bracketed inputs (e.g. `xyz="foo"`) on downgraded components
were initialized using `attrs.$observe()` (which uses `$evalAsync()` under the
hood), while bracketed inputs (e.g. `[xyz]="'foo'"`) were initialized using
`$watch()`. If the downgraded component was created during a `$digest` (e.g. by
an `ng-if` watcher), the non-bracketed inputs were not initialized in time for
the initial call to `ngOnChanges()` and `ngOnInit()`.
This commit fixes it by using `$watch()` to initialize all inputs. `$observe()`
is still used for subsequent updates on non-bracketed inputs, because it is more
performant.
Fixes#16212
Previously, when using a different property/attribute name for an upgraded
component's binding (e.g. `bindings: {propName: '<attrName'}`), the property and
attribute names were swapped (e.g. using `attrName` as the property name and
`propName` as the attribute name). This resulted in unexpected behavior.
This commit fixes this using the correct names for properties and attributes.
This only affects `upgrade/dynamic`. `upgrade/static` works correctly already.

DEPRECATION:

The main use case for the generated source maps is to give
errors a meaningful context in terms of the original source
that the user wrote.
Related changes that are included in this commit:
* renamed virtual folders used for jit:
* ng://<module type>/module.ngfactory.js
* ng://<module type>/<comp type>.ngfactory.js
* ng://<module type>/<comp type>.html (for inline templates)
* error logging:
* all errors that happen in templates are logged
from the place of the nearest element.
* instead of logging error messages and stacks separately,
we log the actual error. This is needed so that browsers apply
source maps to the stack correctly.
* error type and error is logged as one log entry.
Note that long-stack-trace zone has a bug that
disables source maps for stack traces,
see https://github.com/angular/zone.js/issues/661.

- DebugNode.source no more returns the source location of a node.
