Alex Rickabaugh c7c5b2fc1e fix(compiler-cli): correct incremental behavior even with broken imports (#39923 ) When the compiler is invoked via ngc or the Angular CLI, its APIs are used under the assumption that Angular analysis/diagnostics are only requested if the program has no TypeScript-level errors. A result of this assumption is that the incremental engine has not needed to resolve changes via its dependency graph when the program contained broken imports, since broken imports are a TypeScript error. The Angular Language Service for Ivy is using the compiler as a backend, and exercising its incremental compilation APIs without enforcing this assumption. As a result, the Language Service has run into issues where broken imports cause incremental compilation to fail and produce incorrect results. This commit introduces a mechanism within the compiler to keep track of files for which dependency analysis has failed, and to always treat such files as potentially affected by future incremental steps. This is tested via the Language Service infrastructure to ensure that the compiler is doing the right thing in the case of invalid imports. PR Close #39923		2020-12-03 13:42:13 -08:00

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
