This fixes a bug where although multiple stylesheets were being processed by the ext-transforms-plugin we were not properly merging the style documentation for all of those stylesheets, leading to a race condition where whichever file was processed last would set the style docs for the whole component. Not good!

To fix the issue we just need to merge the style docs for the various stylesheets together (de-duping on the name property).

What is the current behavior?

The last stylesheet to be processed 'wins' and defines the styleDocs property on the ComponentCompilerMetadata for a given component.

What is the new behavior?

As new StyleDocs come in we merge them into one array, to ensure we're collecting them all.

Does this introduce a breaking change?

  • Yes
  • No

Testing

This functionality is a bit difficult to unit-test, so I stood up a test project similar to the one we already have for testing the docs-json output target. It includes a reproduction of the issue, where a component has two css files associated with it in styleUrls which both have CSS props documented in them. Both of these should show up in the README for the file.

LGTM!

This fixes a bug where although multiple stylesheets were being
processed by the `ext-transforms-plugin` we were not properly merging
the style documentation for all of those stylesheets, leading to a race
condition where whichever file was processed last would set the
style docs for the whole component. Not good!

To fix the issue we just need to merge the style docs for the various
stylesheets together (de-duping on the `name` property).

This also adds a test project in `test/docs-readme` which exercises this
functionality.
