Previously, ngtsc attempted to use the .d.ts schema for HTML elements to check bindings to DOM properties. However, the TypeScript lib.dom.d.ts schema does not perfectly align with the Angular DomElementSchemaRegistry, and these inconsistencies would cause issues in apps. There is also the concern of supporting both CUSTOM_ELEMENTS_SCHEMA and NO_ERRORS_SCHEMA which would have been very difficult to do in the existing system. With this commit, the DomElementSchemaRegistry is employed in ngtsc to check bindings to the DOM. Previous work on producing template diagnostics is used to support generation of this different kind of error with the same high quality of error message. PR Close #32171 |

fake_core is a library designed to expose some of the same symbols as @angular/core, without
requiring compilation of the whole of @angular/core. This enables unit tests for the compiler to
be written without incurring long rebuilds for every change.
@angular/coreis compiled with@angular/compiler-cli, and therefore has an implicit dependency on it. Therefore core must be rebuilt if the compiler changes.- Tests for the compiler which intend to build code that depends on
@angular/coremust have a data dependency on@angular/core. Therefore core must be built to run the compiler tests, and thus rebuilt if the compiler changes.
This rebuild cycle is expensive and slow. fake_core avoids this by exposing a subset of the
@angular/core API, which enables applications to be built by the ngtsc compiler without
needing a full version of core present at compile time.
