In which of these areas are you experiencing a problem?
App
Expected behavior
The app preview of a complex app with a lot of extensions loads fast - as it always did.
Actual behavior
The app preview of a complex app with a lot of extensions takes minutes to load or sometimes it doesn’t load at all, it freezes.
I’ve pinpointed the issue to this change in November as of 3.87.0, if the extensions are now all watching for changes in imported files, it means the watching strategy is not optimal enough for large apps, if the extensions import intricate files that are used in the repository, it seems to hog the app preview process by a lot, many times just freezing and not continuing.
This can be considered a breaking change for large apps such as ours, we have to conform to 3.86.1 for now while this issue is fixed, otherwise we can’t use a CLI version to develop.
Reproduction steps
- Have a complex app that has a lot of extensions, shared code outside of the extensions folder that is imported by the extensions and also the app.
- Run the dev server preview.
- See that it takes ages to load or sometimes it just freezes.
