Peer dependency for @typescript-eslint/parser@^7.0.0

[kjetilkh-politiet]

Hi, is it possible to add peer dependency for @typescript-eslint/parser@^7.0.0?

To be clear, this is causing errors like this while linting, if the ESLint config uses a v7+ version of the typescript-eslint packages:

$ yarn eslint . --max-warnings 0
$ /home/runner/work/courses/courses/node_modules/.bin/eslint . --max-warnings 0
(node:2195) ExperimentalWarning: Importing JSON modules is an experimental feature and might change at any time
(Use `node --trace-warnings ...` to show where the warning was created)
Oops! Something went wrong! :(
ESLint: 9.0.0
Error: Error while loading rule 'jsx-expressions/strict-logical-expressions': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

typescript-eslint v8 was released on 31 July 2024:

• https://x.com/tseslint/status/1818709751389102376

So it would probably be good to update to v8 instead of v7.

Is anyone having this problem for ESLint 8? I've attempted upgrading our monorepo which is using [email protected] to [email protected] and have not encountered any problems that would prevent the upgrade.
