Igor Minar d578ab8f3c build: simplify package.jsons for all of our packages (#36944)
We can remove all of the entry point resolution configuration from the package.json
in our source code as ng_package rule adds the properties automatically and correctly
configures them.

This change simplifies our code base but doesn't have any impact on the package.json
in the distributed npm_packages.

README.md

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/core is 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/core must 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.
