Support Rollup v3.x.x

[michalica]

Expected behavior

Support for rollup v3 and later

Actual Behavior

Support only v2

Additional context

is there a plan to support rollup v3? I could not find any issue related to this in the repo.

What is the status on Rollup 3 support? The last release of Rollup 2 seem to have been 2.79.1 about 5 months ago, it would be great to be able to keep up while using the open-wc packages.

Unfortunately, most of us are busy with other projects at the moment. We would need to get together to discuss this.

Personally, I don't have much experience with Rollup internals, although I'd love to learn more and dive into the topic.
But without proper plan and at least some tentative agreement on what to do, I don't know how to approach this.

@daKmoR @LarsDenBakker @thepassle @Westbrook @43081j would you be ok to have a call on Rollup 3 plans?

[thepassle]

Support rollup v3 in what, exactly? Is anything particularly blocked on not using rollup v3? The breaking changes in rollup v3 are very minimal, most things should just kind of work with it.

I'm mostly talking about Web Dev Server and its internals (that also affect Web Test Runner), there are some issues there.
Especially this one modernweb-dev/web#1700 is basically a blocker for newer versions of @rollup/plugin-commonjs.

Im confused, those are modern web projects (not open-wc) and those dont necessarily have anything to do with updating to rollup v3?

even older versions are broken now afaik. the commonjs support in modernweb is extremely lacking, probably due to the mw team not using commonjs themselves anymore i suspect.

pretty sure its meant to be a modernweb issue.

dropping openwc and moving everything into modernweb would solve such confusions, just saying :D

also happy to collab/discuss on whatever support might be needed

I'd be happy to transfer the issue but looks like it can't be done across different GitHub organisations. Let me create a new one instead.

It looks like these now require rollup v3 as of Friday:
https://github.com/modernweb-dev/web/releases/tag/%40web%2Fdev-server%400.2.0
https://github.com/modernweb-dev/web/releases/tag/%40web%2Ftest-runner%400.16.0

When I try to use the new versions above with @open-wc/building-rollup, @web/dev-server and @web/test-runner will install their own local copies of rollup.

@Westbrook @koddsson I noticed #2663, will the rollup version also be bumped as part of the upcoming release?

That's the plan! See #2649 by @Westbrook for the actual change. #2663 was a PR to that PR.
