Pete Bacon Darwin a185efbd60 perf(ngcc): read dependencies from entry-point manifest (#36486)
Previously, even if an entry-point did not need to be processed,
ngcc would always parse the files of the entry-point to compute
its dependencies. This can take a lot of time for large node_modules.

Now these dependencies are cached in the entry-point manifest,
and read from there rather than computing them every time.

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.

Building

The project is built using Bazel:

yarn bazel build //packages/compiler-cli/ngcc

Unit Testing

The unit tests are built and run using Bazel:

yarn bazel test //packages/compiler-cli/ngcc/test

Integration Testing

There are tests that check the behavior of the overall executable:

yarn bazel test //packages/compiler-cli/ngcc/test:integration
