What kind of change does this PR introduce?
Which package are you modifying?
What is the current behavior?
All packages containing
fesm2022
in the filename were transformed to es2016 using esbuild. This causes slower performance when running tests with Vitest in Angular.Closes #
What is the new behavior?
By default, only filenames containing
cdk/fesm2022
are transformed using esbuild. This drastically improves performance when running tests with Vitest in Angular, while keeping compatibility with existing tests.Additional files can be added to the transform using the
ssr.noExternal
array in thevite.config.ts
but this satisfies using Angular component harness tests as well as regular unit tests using async/await.Does this PR introduce a breaking change?
