This commit adds an API to `NgCompiler`, a method called `getComponentsWithTemplateFile`. Given a filesystem path to an external template file, it retrieves a `Set` (actually a `ReadonlySet`) of component declarations which are using this template. In most cases, this will only be a single component. This information is easily determined by the compiler during analysis, but is hard for a lot of Angular tooling (e.g. the language service) to infer independently. Therefore, it makes sense to expose this as a compiler API. PR Close #39002
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules
compiled with ngc
, into node_modules
which
appear to have been compiled with ngtsc
.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
