ngtsc used to assume that all .d.ts dependencies (that is, third party
packages) were imported via an absolute module path. It turns out this
assumption isn't valid; some build tools allow relative imports of
other compilation units.
In the absolute case, ngtsc assumes (and still does) that all referenced
types are available through the entrypoint from which an @NgModule was
imported. This commit adds support for relative imports, in which case
ngtsc will use relative path resolution to determine the imports.

There is a bug in the existing handling for cross-file references.
Suppose there are two files, module.ts and component.ts.
component.ts declares two components, one of which uses the other.
In the Ivy model, this means the component will get a directives:
reference to the other in its defineComponent call.
That reference is generated by looking at the declared components
of the module (in module.ts). However, the way ngtsc tracks this
reference, it ends up comparing the identifier of the component
in module.ts with the component.ts file, detecting they're not in
the same file, and generating a relative import.
This commit changes ngtsc to track all identifiers of a reference,
including the one by which it is declared. This allows toExpression()
to correctly decide that a local reference is okay in component.ts.
PR Close#25080
When ngtsc encounters a reference to a type (for example, a Component
type listed in an NgModule declarations array), it traces the import
of that type and attempts to determine the best way to refer to it.
In the event the type is defined in the same file where a reference
is being generated, the identifier of the type is used. If the type
was imported, ngtsc has a choice. It can use the identifier from the
original import, or it can write a new import to the module where the
type came from.
ngtsc has a bug currently when it elects to rely on the user's import.
When writing a .d.ts file, the user's import may have been elided as
the type was not referred to from the type side of the program. Thus,
in .d.ts files ngtsc must always assume the import may not exist, and
generate a new one.
In .js output the import is guaranteed to still exist, so it's
preferable for ngtsc to continue using the existing import if one is
available.
This commit changes how @angular/compiler writes type definitions, and
allows it to use a different expression to write a type definition than
is used to write the value. This allows ngtsc to specify that types in
type definitions should always be imported. A corresponding change to
the staticallyResolve() Reference system allows the choice of which
type of import to use when generating an Expression from a Reference.

Fixes#25018.
Instantiating a NgModuleRef from NgModuleFactory reuses the NgModuleDefinition if it is already present. However the NgModuleDefinition has a providers array which modified when tree shakable providers are instantiated. This corrupts the provider definitions the next time the same factory is used to create a new NgModuleRef - Two provider definitions can end up with the same index anf the injector could potentially return a completely wrong object for a provider token.
This scenario is more likely on the server where the same NgModuleFactory is reused across requests.
The fix clones the cached NgModuleDefinition so that any tree shakable providers added later do not affect the cached copy.

Ivy definition types have a generic type which specifies the return
type of the factory function. For example:
static ngDirectiveDef<NgForOf, '[ngFor][ngForOf]'>
However, in this case NgForOf itself has a type parameter <T>. Thus,
writing the above is incorrect.
This commit modifies ngtsc to understand the genericness of NgForOf and

static ngDirectiveDef<NgForOf<any>, '[ngFor][ngForOf]'>

Previously ngtsc would use a tuple of class types for listing metadata
in .d.ts files. For example, an @NgModule's declarations might be
represented with the type:
[NgIf, NgForOf, NgClass]
If the module had no declarations, an empty tuple [] would be produced.
This has two problems.
1. If the class type has generic type parameters, TypeScript will
complain that they're not provided.
2. The empty tuple type is not actually legal.
This commit addresses both problems.
1. Class types are now represented using the `typeof` operator, so the
above declarations would be represented as:
[typeof NgIf, typeof NgForOf, typeof NgClass].
Since typeof operates on a value, it doesn't require generic type
arguments.
2. Instead of an empty tuple, `never` is used to indicate no metadata.

Previously, references had the concept of an identifier, but would not
properly detect whether the identifier should be used or not when
generating an expression. This change fixes that logic.
Additionally, now whenever an identifier resolves to a reference (even

the reference is updated to use that identifier. This ensures that for
a class Foo declared in foo.ts, but referenced in an expression in
bar.ts, the Reference returned includes the identifier from bar.ts,
meaning that writing an expression in bar.ts for the Reference will not

exports contain not only other modules (which will have ngInjectorDef
fields), but components, directives, and pipes as well. Because of

It's not impossible, but for now filtering them out at runtime will

@NgModule()s get compiled to two fields: ngModuleDef and ngInjectorDef.
Both fields contain imports, as both selector scopes and injectors have
the concept of composed units of configuration. Previously these fields
were generated by static resolution of imports and exports in metadata.
Support for ModuleWithProviders requires they be generated differently.
ngModuleDef's imports/exports are generated as resolved lists of types,
whereas ngInjectorDef's imports should reflect the raw expressions that
the developer wrote in the metadata.
This change modifies the NgModule handler and properly copies raw nodes
for the imports and exports into the ngInjectorDef.

Within an @NgModule it's common to include in the imports a call to
a ModuleWithProviders function, for example RouterModule.forRoot().
The old ngc compiler was able to handle this pattern because it had
global knowledge of metadata of not only the input compilation unit
but also all dependencies.
The ngtsc compiler for Ivy doesn't have this knowledge, so the
pattern of ModuleWithProviders functions is more difficult. ngtsc
must be able to determine which module is imported via the function
in order to expand the selector scope and properly tree-shake
directives and pipes.
This commit implements a solution to this problem, by adding a type
parameter to ModuleWithProviders through which the actual module
type can be passed between compilation units.
The provider side isn't a problem because the imports are always
copied directly to the ngInjectorDef.

such as enumerating decorators on a type, reading metadata from constructor

structures over which this reflection takes place can be very different. For
example, in TS/ES6 code `class` declarations are `ts.ClassDeclaration` nodes,
but in ES5 code they've been downleveled to `ts.VariableDeclaration` nodes that
are initialized to IIFEs that build up the classes being defined.

Fixes#23280, #23133.
This fix lets code access DOM types like Node, HTMLElement in the code. These are invariant across requests and the corresponding classes from Domino can be safely provided during platform initialization.
This is needed for the current sanitizer to work properly on platform-server. Also allows HTML types in injection - Ex. `@inject(DOCUMENT) doc: Document`.

Previously event handlers on the server were setup directly. This change makes it so that the event registration on the server go through EventManagerPlugin just like on client. This allows us to add custom event registration handlers on the server which allows us to hook up preboot event handlers cleanly.

In ngIvy directives matching (determining which directives are active based
on a CSS seletor) happens at runtime. This means that runtime needs to have
enough context to match directives. This PR takes care of cases where a directive's
selector should match bindings (ex. [foo]="exp") and event handlers (ex. (out)="do()").
In the mentioned cases we need to have binding / output "attributes" for directive's
CSS selector matching purposes. At the same time those are not regular attributes and
as such should not be reflected in the DOM.

Allows to write:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { pure: false } })
.createComponent(MenuComponent);
when you only want to set the `pure` metadata,
instead of currently:
const fixture = TestBed
.overridePipe(DisplayNamePipe, { set: { name: 'displayName', pure: false } })
.createComponent(MenuComponent);
which forces you to redefine the name of the pipe even if it is useless.

Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.
Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.
Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:
* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
Angular related transforms, which approximates the behavior of plain
tsc. This allows the main packages such as common to be tested with
the JIT compiler.
Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.

Short-circuitable expressions (using ternary & binary operators) could not use
the regular binding mechanism as it relies on the bindings being checked every
single time - the index is incremented as part of checking the bindings.
Then for pure function kind of bindings we use a different mechanism with a
fixed index. As such short circuiting a binding check does not mess with the
expected binding index.
Note that all pure function bindings are handled the same wether or not they
actually are short-circuitable. This allows to keep the compiler and compiled
code simple - and there is no runtime perf cost anyway.

This commit adds a mechanism by which the @angular/core annotations
for @Component, @Injectable, and @NgModule become decorators which,
when executed at runtime, trigger just-in-time compilation of their
associated types. The activation of these decorators is configured
by the ivy_switch mechanism, ensuring that the Ivy JIT engine does
not get included in Angular bundles unless specifically requested.

Since `versionedFiles` behaves in the exact same way as `files`, there
is no reaason to have both. Users should use `files` instead.
This commit deprecates the property and prints a warning when coming
across an asset-group that uses it. It should be completely removed in
a future version.
Note, it has also been removed from the default `ngsw-config.json`
template in angular/devkit#754.

Closure compiler with type based optimizations has a bug where externs for inherited static fields are not being honored. For Angular Elements this meant that 'observedAttributes' static field which is marked as an extern for the base HTMLElement class was getting renamed.
This commit works around the bug by using quoted access of 'observedAttributes' that explicitly prevents the renaming.

The recognizer code used to call Object.freeze() on queryParams before
using them to construct ActivatedRoutes, with the intent being to help
avoid common invalid usage. Unfortunately, Object.freeze() works
in-place, so this was also freezing the queryParams on the actual
UrlTree object, making it more difficult to manipulate UrlTrees in
things like UrlHandlingStrategy.
This change simply shallow-copies the queryParams before freezing them.

This commits changes how clients are added in `SwTestHarness`, so that
the behavior in tests closer mimics what would happen in an actual
ServiceWorker.
It also removes auto-adding clients when calling `clients.get()`, which
could hide bugs related to non-existing clients.

Previously, the compileComponent() and compileDirective() APIs still required
the output of global analysis, even though they only read local information
from that output.
With this refactor, compileComponent() and compileDirective() now define
their inputs explicitly, with the new interfaces R3ComponentMetadata and
R3DirectiveMetadata. compileComponentGlobal() and compileDirectiveGlobal()
are introduced and convert from global analysis output into the new metadata
format.
This refactor also splits out the view compiler into separate files as
r3_view_compiler_local.ts was getting unwieldy.
Finally, this refactor also splits out generation of DI factory functions
into a separate r3_factory utility as the logic is utilized between different
compilers.

Previously, ngOnDestroy was only called on services which were statically
determined to have ngOnDestroy methods. In some cases, such as with services
instantiated via factory functions, it's not statically known that the service
has an ngOnDestroy method.
This commit changes the runtime to look for ngOnDestroy when instantiating
all DI tokens, and to call the method if it's present.
