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.
