Suport ESLint v9

[bmulholland]

Separately from flat config, ESLint v9 dropped several deprecated APIs, including context.getScope, which this plugin uses. Those need to be replaced.

@Sv443 It is not. Flat config was available in ESLint 8, and is optional in ESLint 9. My issue specifically says "separately from flat config," which I guess you missed?

This plugin also depends on a very old version of @typescript-eslint/utils ^5.62.0.
That version of @typescript-eslint/utils does not support ESLint 9, which causes yarn dependency resolution to fail

Hey @maxpatiiuk seems like the typescript utils only support ESLint v9 in an alpha version, which is a bummer.

I'm honestly not sure if it's possible to support both v8 and v9 of ESLint..

Yes, it's a tricky situation.

Options:

• The v8 version of @typescript-eslint/utils supports both ESLint 8 and 9: https://github.com/typescript-eslint/typescript-eslint/blob/9dce771b8dd4edae252af388b3767b95dfb007f3/packages/utils/package.json#L72
• You can use a simple bundler like tsup to bundle-in the parts of @typescript-eslint/utils that are needed by your library. Then, you package will declare @typescript-eslint/utils as a devDependency rather than a dependency, avoiding the package manager complaints
• Wait 1-2 months for typescript-eslint v8 to have a stable release and to be more widely used. Until then, publish the eslint v9 version of eslint-plugin-storybook as a separate npm tag

edit: lack of eslint 9 support in this package is not a deal breaker for us (we can temporary disable it). a few other packages we have a bigger blockers, and we must wait as the ecosystem churns a bit

Something that might influence the decision: ESLint v8 is EOL in less than two months. https://eslint.org/version-support/

The best solution might be to drop support for v8. If anyone needs to use ESLint v8, they can use the current version of this package (0.8.0) instead of the latest version.

@yannbf If the alpha status is the dealbreaker here, typescript-eslint@8 is no longer in alpha. latest is currently v8.1.0.
