Paul Gschwendtner 2df8584619 refactor(compiler-cli): speed up compiler tests by caching Angular (#54650)
Currently the `makeProgram` utility from `ngtsc/testing` does not use
the test host by default- optimizing for source file caching.

Additionally, the host can be updated to attempt caching of the `.d.ts`
files from `@angular/core`— whether that's fake core, or the real core-
is irrelevant. We are never caching if these changes between tests, so
correctness is guaranteed.

This commit reduces the type check test times form 80s to just 11
seconds, faster than what it was before with `fake_core`. The ngtsc
tests also run significantly faster. From 40s to 30s

README.md feat(language-service): Provide plugin to delegate rename requests to Angular (#44696) 2022-01-21 11:18:48 -08:00

Override Rename Ts Plugin

When the user wants to rename a symbol in the ts file VSCode will ask the rename providers for the answer in turn. If the first extension returns the result, the VSCode will break the loop and apply the result. If the first extension cannot rename the symbol, VSCode will ask the second extension in the list (built-in TS/JS extension, Angular LS extension, etc.). In other words, VSCode takes the result from only one rename provider and the order depends on registration timing, scoring.

Because the built-in ts extension and Angular extension have the same high score, if the built-in ts extension is the first(depends on the time the extension was registered), the result will be provided by the built-in extension. We want Angular to provide it, so this plugin will delegate rename requests and reject the request for the built-in ts server.

The Angular LS only provides the rename info when working within an Angular project. If we cannot locate Angular sources in the project files, the built-in extension should provide the rename info.

This plugin will apply to the built-in TS/JS extension and delegate rename requests to the Angular LS. It provides the rename info only when it is an Angular project. Otherwise, it will return info by the default built-in ts server rename provider.
