Update peer dependencies to include `@typescript-eslint/parser` v6

[SuperKXT]

Typescript-eslint just released v6. I'm getting a peer dependency mismatch warning after updating.

[bcentdev]

Hello, @hluisson , please :) 🔝

[karlhorky]

Here's the warning that appears (with pnpm):

$ pnpm install
 WARN  Issues with peer dependencies found
.
└─┬ eslint-plugin-jsx-expressions 1.3.1
  └── ✕ unmet peer @typescript-eslint/parser@"^4.0.0 || ^5.0.0": found 6.2.1

[karlhorky]

And this actually causes a failure with npm when running npm install in a project that uses @typescript-eslint/*@^6.0.0 packages, since npm is a bit more picky with peer dependencies:

$ npm i

@hluisson would you be open to upgrading the peer dependency on @typescript-eslint/parser@^6?

It may also need a switch away from the @typescript-eslint/experimental-utils package to @typescript-eslint/utils, used here:

https://github.com/hluisson/eslint-plugin-jsx-expressions/blob/cb612d1be4c184542987b563422562b42b41486a/package.json#L26-L29

[hluisson]

Hey - this is on my radar, but for fastest resolution feel free to submit a PR!

[DerTimonius]

I'm currently looking into it and noticed the following:

• upgrading not only the peer dependency, but also the dev dependency for @typescript-eslint/parser to ^6 (which I guess would be necessary if the peer dependency is updated) only works if the switch from the @typescript-eslint/experimental-utils package to @typescript-eslint/utils is made as @karlhorky mentioned
• this leads to issues, since RuleTester is now a separate package
  • if this is imported together with the utils package, I can't get the tests to run locally:

    Test suite failed to run
    Cannot find module '@typescript-eslint/utils/eslint-utils' from 'node_modules/@typescript-eslint/rule-tester/dist/RuleTester.js'
    Require stack:
    node_modules/@typescript-eslint/rule-tester/dist/RuleTester.js
    node_modules/@typescript-eslint/rule-tester/dist/index.js
    tests/lib/rules/strict-logical-expressions.test.ts

Another thing I noticed was that a change to the tsconfig.build.json (switching from node to node16 or similar in the moduleResolution) would have to be made according to this issue

I recently tackled upgrading this with what seems like mostly similar issues here: https://github.com/gund/eslint-plugin-deprecation/pull/71

You can look at that for inspiration, otherwise I might get around to making a similar PR here as well soon!

[karlhorky]

Workaround

Until this is fixed, you can override the dependencies to the latest version:

Eg using npm Overrides:

package.json

{
  "overrides": {
    "@typescript-eslint/eslint-plugin": "6.9.1",
    "@typescript-eslint/parser": "6.9.1"
  }
}

(or Yarn Resolutions or pnpm Overrides)

[hluisson]

Hey all - thanks for your patience. I will publish 1.3.2 as soon as possible.

[hluisson]

1.3.2 is now live!

[karlhorky]

@hluisson Thanks so much, I can confirm this is working now, no more peer dependency warnings 🙌
