Previously, metadata registration (the recording of collected metadata during analysis of directives, pipes, and NgModules) was only used to produce the `LocalModuleScope`, and thus was handled by the `LocalModuleScopeRegistry`. However, the template type-checker also needs information about registered directives, outside of the NgModule scope determinations. Rather than reuse the scope registry for an unintended purpose, this commit introduces new abstractions for metadata registration and lookups in a separate 'metadata' package, which the scope registry implements. This paves the way for a future commit to make use of this metadata for the template type-checking system. Testing strategy: this commit is a refactoring which introduces no new functionality, so existing tests are sufficient. PR Close #29698
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.
