ngtsc needs to reflect over code to property compile it. It performs operations
such as enumerating decorators on a type, reading metadata from constructor
parameters, etc.
Depending on the format (ES5, ES6, etc) of the underlying code, the AST
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.
The ReflectionHost abstraction allows ngtsc to perform these operations without
directly querying the AST. Different implementations of ReflectionHost allow
support for different code formats.

This commit builds out enough of the JIT compiler to render
//packages/core/test/bundling/todo, and allows the tests to run in
JIT mode.
To play with the app, run:
bazel run --define=compile=jit //packages/core/test/bundling/todo:prodserver
PR Close#24138
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 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.
PR Close#22005
All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime

identification.

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.

The current `flattenSummaries` function re-process the same NgModule
summary even if it has been processed before. Certain modules like
CommonModule are repeated multiple times in the module tree and it is
expanded out every time.
This was making unit tests using AOT summaries really slow. This will
also slow down JIT bootstrap applications that load AOT summaries for
component libraries.
The fix is to remember which summaries were seen before and not to
process them again.
Each node now has two index: nodeIndex and checkIndex.
nodeIndex is the index in both the view definition and the view data.
checkIndex is the index in in the update function (update directives and update
renderer).
While nodeIndex and checkIndex have the same value for now, having both of them
will allow changing the structure of view definition after compilation (ie for
runtime translations).
For now, we always create all generated files, but diff them

With this change ngc now accepts a `-w` or a `--watch`
command-line option that will automatically perform a
recompile whenever any source files change on disk.

With this commit the compiler will "lower" expressions into exported
variables for values the compiler does not need to know statically
in order to be able to generate a factory. For example:
```
providers: [{provider: 'token', useValue: calculated()}]
```
produced an error as the expression `calculated()` is not supported
by the compiler because `calculated` is not a
[known function](https://angular.io/guide/metadata#annotationsdecorators)
With this commit this is rewritten, during emit of the .js file, into
something like:
```
export var ɵ0 = calculated();
...
provdiers: [{provider: 'token', useValue: ɵ0}]
```
The compiler then will now generate a reference to the exported `ɵ0`
instead of failing to evaluate `calculated()`.

This is needed as the typescript no longer elides type reexports
in the generated code when using transformers.
A nice side effect is that this make summaries shorter and produces
less reexports as we rollup reexports.

Previously, we only did this when setting the `generateCodeForLibraries: false`.
This is needed so that libraries compiled with `generateCodeForLibraries: true` can be used as dependencies of other compilation units.

After this, neither @angular/compiler nor @angular/comnpiler-cli depend
on @angular/core.
This add a duplication of some interfaces and enums which is stored
in @angular/compiler/src/core.ts
BREAKING CHANGE:
- `@angular/platform-server` now additionally depends on
`@angular/platform-browser-dynamic` as a peer dependency.

This change allows users to specify multiple exportAs names for a
directive by giving a comma-delimited list inside the string.
The primary motivation for this change is to allow these names to be
changed in a backwards compatible way.
This also allows to customize the filePaths in `.ngsummary.json` file
via the new methods `toSummaryFileName` and `fromSummaryFileName`
on the `CompilerHost`.
