Any experience with pm+vitest? ("Adding different instances of a keyed plugin")

[tslocke]

Anyone using vitest? (it runs my test suite /dramatically/ faster, btw)

On my first test run, I get a bunch of failures with the PM error “Adding different instances of a keyed plugin”. Oddly, if I re-run the tests they pass without this error.

I’ve checked that I don’t have multiple versions of prosemirror-state installed, and I’ve tried this suggestion:

RangeError: Adding different instances of a keyed plugin (plugin$)

In case someone is interested in the outcome of this specific issue. For my dev environment I managed to resolve it through configuring vitejs appropriately (I think). install prosemirror-model, prosemirror-state, prosemirror-view and prosemirror-transform make the following change in vite.config.js optimizeDeps: { include: [ 'prosemirror-state', 'prosemirror-transform', 'prosemirror-model', 'prosemirror-view' ] } The result of this are 4 separate chunks tha…

Any ideas?

Thanks

Also struggling due to duplicated prosemirror-model. So far, I haven’t been successful in trying to find a config that would fix that problem.

Please check your lock file (e.g., yarn.lock, pnpm-lock.yaml) and ensure that you only have one version of prosemirror-model installed. Commands like npm dedupe and pnpm dedupe will be helpful.

I found it useful to open the lock file, search for “prosemirror” and delete every reference. Then npm install or whatever.
