This PR upgrades `jest-worker` and `jest-cli` to the latest pre-release version, also removed `jest-circus` which is included in Jest by default. `jest-worker@next` includes a fix for memory leak that we need (https://github.com/facebook/jest/pull/11187).
Fixes#22925. This will also improve the OOM issue for `next dev` #15855.
This upgrades to ncc@0.25.0 and fixes the previous bugs including:
* ncc not referenced correctly in build
* Babel type errors
* node-fetch, etag, chalk and raw-body dependencies not building with ncc - these have been "un-ncc'd" for now. As they are relatively small dependencies, this doesn't seem too much of an issue and we can follow up in the tracking ncc issue at https://github.com/vercel/ncc/issues/612.
* `yarn dev` issues
Took a lot of bisecting, but the overall diff isn't too bad here in the end.
This adds inlining for Babel and the Babel plugins used in next.
This is based to the PR at https://github.com/vercel/next.js/pull/18823.
The approach is to make one large bundle and then separate out the individual packages from that in order to avoid duplications.
In the first attempt the Babel bundle size was 10MB... using "resolutions" in the Yarn workspace to reduce the duplicated packages this was brought down to a 2.8MB bundle for Babel and all the used plugins which is exactly the expected file size here.
This will thus add a 2.8MB download size to the next package, but save downloading any babel dependencies separately, removing a large number of package dependencies from the overall install.
This updates to the latest ncc@0.24.1 release.
Initially I thought chalk needed to be removed to make this work, but it turns out it was a caching issue.
I've also added a cache clear to the rebuild command to avoid these issues hopefully in future.
