Support ESLint 8.x

[MichaelDeBoey]

ESLint v8.0.0 is released 🎉

It would be awesome to have official ESLint 8 support. 👊
I'm happy to help where I can of course 🙂

Hi!

I assume this is what you opened the issue about?

❯ npm i -D eslint-config-prettier
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR! 
npm ERR! While resolving: undefined@undefined

Adding --force it manages to install:

And everything seems to work.

The peer dependency on ESLint is set to >=7.0.0, so it’ll Just Work when ESLint 8.0.0 is released. At some point after that I’ll go through and update this repo and only test with ESLint 8 going forward.

If you know of a peer dependency range that includes pre-releases I’m all ears!

I’m going to close this since ESLint 8.0.0 has been released and eslint-config-prettier works with ESLint 8.0.0.
