Bundle

js_expected_symbol_test

This folder contains tests which assert that most of the code is tree shaken away. This is asserted by keeping gold files of all symbols which are expected to be retained. When doing renaming it is often necessary to update the gold files; to do so use these scripts:

yarn run symbol-extractor:check
yarn run symbol-extractor:update

Debugging

You can inspect the build output of each project by building the :bundles target.

yarn bazel build //packages/core/test/bundling/standalone_bootstrap:bundles

This output is always unmangled and can be easily used for debugging. Alternatively, you can also serve the output by running:

yarn bazel run //packages/core/test/bundling/standalone_bootstrap:bundles.serve

If needed, you can also control the Angular CLI optimizations via environment variables that you can set via the env attribute in BUILD.bazel of each test.
