I looked into upgrading eslint on Hydrogen. Currently block by other eslint plugins not supporting eslint 9.x:

So far I have figure out the following hasn't support eslint 9.x

• @remix-run/eslint-config
• eslint-plugin-jest

Biggest one being @remix-run/eslint-config pinning the parser @typescript-eslint/parser
at 5.x where the latest is at 8.x which supports eslint 9.x.

We can nudge Remix team on updating @remix-run/eslint-config
Also need to fix or kill eslint-plugin-hydrogen

@wizardlyhel Thank you for the response!

I think @remix-run/eslint-config is deprecated:

• Eslint v9 support for `@remix-run/eslint-config` remix-run/remix#10054
• Deprecate Remix ESLint Config remix-run/remix#7056
• Remove @remix-run/eslint-config dependency remix-run/remix#7597

Yea - just talked with the Remix team. We'll also move that dependency
