In applications that make heavy use of lazy routes and ES2015 libraries, this option can improve bundle sizes. It might also break your bundles in ways we don't understand fully, so please test and report any problems you find.
NOTE: the following are known problems with experimentalRollupPass
- vendorChunk, commonChunk, namedChunks: these won't work, because by the time webpack sees the chunks, the context of where they came from is lost.
- webWorkerTsConfig: workers must be imported via a root relative path (e.g.`app/search/search.worker`) instead of a relative path (`/search.worker`) because of the same reason as above.
- loadChildren string syntax: doesn't work because rollup cannot follow the imports.
* test: update ng-packagr builder tests to work on Windows
* build: add ng packagr test large for ivy
* test: fix web-worker test in ivy
Previously, we were not testing web workers under Ivy as we were overriding tsconfig.app.json entirely without including enableIvy.
When enabling Ivy we are getting warning of files that are part of the compilation which causing a warning to show and break the test.
* build: update ng-packagr to `^5.4.0`
* test: display ivy mode message once
