From 7b31db9f601d106c8b9ce6ba9ed26bacee9ebaee Mon Sep 17 00:00:00 2001 From: Jiachi Liu Date: Sat, 22 Oct 2022 16:33:51 -0700 Subject: [PATCH] Bundle ssr client layer excepts react externals (#41606) Bundle the ssr client layer for RSC, this solves the problem when there's an esm package is using on client components, but esm imports the installed react instead of the built-in react version since esm imports is not intercepted by require hook. After bundling the ssr client layer and treating react as externals, now react compiles as cjs externals and could be intercepted by require hook, other code are bundled together which can also get optimized. ## Feature - [ ] Implements an existing feature request or RFC. Make sure the feature request has been accepted for implementation before opening a PR. - [ ] Related issues linked using `fixes #number` - [x] Integration tests added - [ ] Documentation added - [ ] Telemetry added. In case of a feature if it's used or not. - [ ] Errors have a helpful link attached, see `contributing.md` Co-authored-by: Shu Ding Co-authored-by: JJ Kasper --- package.json | 6 +-
