Pete Bacon Darwin c77656e2dd fix(ngcc): handle imports in dts files when processing UMD (#34356)
When statically evalulating UMD code it is possible to find
that we are looking for the declaration of an identifier that
actually came from a typings file (rather than a UMD file).

Previously, the UMD reflection host would always try to use
a UMD specific algorithm for finding identifier declarations,
but when the id is actually in a typings file this resulted in the
returned declaration being the containing file of the declaration
rather than the declaration itself.

Now the UMD reflection host will check to see if the file containing
the identifier is a typings file and use the appropriate stategy.

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
