Using eslint-plugin-import in a monorepo

[cmdcolin]

Hi there
I was wondering if there is any way I can use eslint-plugin-import to catch errors from bad imports in a monorepo

I noticed if I have a monorepo setup like this

• packages/app1 has is-even in it's package.json
• packages/app2 does not have is-even in its package.json
• packages/app2 tries to use is-even

I'd like to get a warning from packages/app2's bad usage of is-even, but I don't get this

I made a small reproducible repo here https://github.com/cmdcolin/yarn_workspaces_eslint_plugin_import (run yarn && yarn lint from root of the repo) and there are no warnings from lint, though it would be cool to see if I can get warnings from this...

Note: I tried cross-posting this to stackoverflow too

no-extraneous-dependencies should be handling this.

I see! I think that helps a lot. Is this rule disabled by default? Enabling it definitely seems to fix the issue in my small demo repo and probably also in my larger repo

will close for now as I think this is effectively solved, thanks!

All rules are disabled by default.

I meant, is it not part of plugin:import/recommended?
my small demo repo only had that enabled and it didn't catch the error but manually adding the import/no-extraneous-dependencies did fix

I don't believe it is, no. I'd suggest using the airbnb config :-)

we can't update the recommended config without a major bump, so it's quite behind.
