Closes #11374

BREAKING CHANGE: Requires ESLint@^8.0.0

[ahummel25]

Any timeline for this getting fixed/merged now that eslint v8 is live?

[MichaelDeBoey]

@ahummel25 As you can see in the OP, not all dependencies are updated for ESLint 8.x (yet), so we'll have to wait for them first.

[karlhorky]

@MichaelDeBoey should jest-community/eslint-plugin-jest#940 be added to the eslint-plugin-jest list above? It seems like this was just merged?

This was released in a minor (25.1.0): https://github.com/jest-community/eslint-plugin-jest/releases/tag/v25.1.0

[ianldgs]

Friendly ping: I think everything is merged now!

[MichaelDeBoey]

@ianldgs I'll update the PR whenever I have some time 👍

[dannyphillips]

Any update on when we plan to merge/release this?

[raix]

@MichaelDeBoey seems like some tests are still failing - I could not find any relations in the eslint release notes but we could try to update to 8.3.0 and see if that fixes anything - if not we'll have to take a closer look cc. @iansu @mrmckeb

[raix]

Actually the main branch seems to be failing in node 16/mac os on the same test "uses yarn as the package manager" - Will have to investigate

[GoetzGoerisch]

@raix looks like a timeout only problem for me.
The PR integration tests run fine on our fork. umati#1

[mrmckeb]

@MichaelDeBoey, this is great - thanks. We'd like to merge this in, but it looks like there are some dependency updates.

If you can take a look, that would be great. Otherwise I can jump in and help!

It might also be worth bumping to ESLint 8.3.0 (and spot check the other versions).

[raix]

Tests should be fixed on main now 🤞

[GoetzGoerisch]

@MichaelDeBoey rebased and updated branch here: https://github.com/umati/create-react-app/tree/eslint-8 please integrate if you like.

[MichaelDeBoey]

@mrmckeb I've rebase this onto main and updated all ESLint related packages to their latest version, so I think this one is good to be merged now
