The style and babel compilers don't have warnings propagated here, although I suppose we could do that in the future.

Why not return all the diagnostics instead of just the warnings and the consumer decide what to do with the diagnostics?

Looking at the oss compiler, all Error
diagnostics cause an exception. There are no Log
and Fatal
level Diagnostics. That effectively leaves only Warning
level diagnostics that can be present in this output.
This declaration makes an implicit behavior, explicit.

Correct. I can add a comment to this effect.

It would be a nice improvement to pass the file name to the template compiler to produce more meaningful diagnostics.

Agreed, but I left it out of this PR. We can always do it in the future, and the test verifies that the file
property is correct.

Fixes #2771
Propagates template compiler warnings from
@lwc/compiler
to@lwc/rollup-plugin
, where it is logged using the standard Rollupthis.warn()
method as a RollupWarning.Here is what a warning looks like when running
rollup
in the console (source:Screenshot:
Does this pull request introduce a breaking change?
Does this pull request introduce an observable change?
If you're using the Rollup plugin directly (e.g. off-core), and if you were using
onwarn
to capture warnings, it previously would never be called. Now it will be called with aRollupWarning
