Currently `ngc-wrapped` mostly relies on any casts/or disabled
strictness checks to be able to use `tsickle`'s emit callback and
emit result merging for ngtsc. We should change this so that supertypes
of `ts.EmitResult` can be used in these optional callbacks- allowing us
to enable strictness checks in `packages/bazel/...` too.

This commit finishes the removal of View Engine from the codebase, deleting
those pieces of @angular/compiler which were only used for VE.

As outlined in the previous commit which enabled the `esModuleInterop`
TypeScript compiler option, we need to update all namespace imports
for `typescript` to default imports. This is needed to allow for
TypeScript to be imported at runtime from an ES module.
Similar changes are needed for modules like `semver` where the types incorrectly
suggest named exports that will not exist at runtime when imported from ESM.
This commit refactors all imports to match with the lint rule we have
configured in the previous commit. See the previous commit for more
details on why certain imports have been changed.
A special case are the imports to `@babel/core` and `@babel/types`. For
these a special interop is needed as both default imports, or named
imports break the other module format. e.g default imports would work
well for ESM, but it breaks for CJS. For CJS, the named imports would
only work, but in ESM, only the default export exist. We work around
this for now until the devmode is using ESM as well (which would be
consistent with prodmode and gives us more valuable test results). More
details on the interop can be found in the `babel_core.ts` files (two
interops are needed for both localize/or the compiler-cli).

In #33551, a bug in `ngc --watch` mode was fixed so that a component is
recompiled when its template file is changed. Due to insufficient
normalization of files paths, this fix did not have the desired effect
on Windows.
Fixes#32869
PR Close#34015
When the Angular compiler is operated through the ngc binary in watch
mode, changing a template in an external file would not cause the
component to be recompiled if Ivy is enabled.
There was a problem with how a cached compiler host was present that was
unaware of the changed resources, therefore failing to trigger a
recompilation of a component whenever its template changes. This commit
fixes the issue by ensuring that information about modified resources is
correctly available to the cached compiler host.

Optimizations to skip compiling source files that had not changed
did not account for the case where only a resource file changes,
such as an external template or style file.
Now we track such dependencies and trigger a recompilation
if any of the previously tracked resources have changed.
This will require a change on the CLI side to provide the list of
resource files that changed to trigger the current compilation by
implementing `CompilerHost.getModifiedResourceFiles()`.

The performCompilation() is always called with an undefined oldProgram option (even in watch mode).
This was regression introduced in: 957be960d2

This also changes the compiler so that we throw less often
on structural changes and produce a meaningful state
in the `ng.Program` in case of errors.

If no user files changed:
- only type check the changed generated files
Never emit non changed generated files
- we still calculate them, but don’t send them through
TypeScript to emit them but cache the written files instead.
PR Close#19646
For now, we always create all generated files, but diff them
before we pass them to TypeScript.
For the user files, we compare the programs and only emit changed
TypeScript files.
This also adds more diagnostic messages if the `—diagnostics` flag
is passed to the command line.
- don’t regenerate code for .d.ts files when
an oldProgram is passed to `createProgram`
- cache `fileExists` / `getSourceFile` / `readFile` in watch mode
- refactor tests to share common code in `test_support`
- support `—diagnostic` command line to print total time
used per watch mode compilation.
PR Close#19275
We now create 2 programs with exactly the same fileNames and
exactly the same `import` / `export` declarations,
allowing TS to reuse the structure of first program
completely. When passing in an oldProgram and the files didn’t change,
TS can also reuse the old program completely.
This is possible buy adding generated files to TS
in `host.geSourceFile` via `ts.SourceFile.referencedFiles`.
This commit also:
- has a minor side effect on how we generate shared stylesheets:
- previously every import in a stylesheet would generate a new
`.ngstyles.ts` file.
- now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
This was required as we need to be able to determine the program files
without loading the resources (which can be async).
- makes all angular related methods in `CompilerHost`
optional, allowing to just use a regular `ts.CompilerHost` as `CompilerHost`.
- simplifies the logic around `Compiler.analyzeNgModules` by introducing `NgAnalyzedFile`.
