This update is not possible yet because most plugins don't support eslint 9 yet. I started migration work for the other ones

Waiting for:

• Support eslint v9 import-js/eslint-plugin-import#2948
• eslint v9 support airbnb/javascript#2961
• Support "Flat Config" (ESLint 9) iamturns/eslint-config-airbnb-typescript#331
• Support ESLint 9 and Flat config eslint-community/eslint-plugin-promise#449

@qwerty287 I did some further testing to update to v9. https://github.com/antfu/eslint-config seems to be a quite common preset including a nice set of rules. I've also added @intlify/eslint-plugin-vue-i18n to detect missing translations. What do you think?

[qwerty287]

In general looks fine, but I didn't look into details.
If we still have most of the linters we had before I'm totally fine it.

@anbraten Can you take a look at my recent commits?

I'm fine with using antfu so far.

What I changed:

• enabled some additional plugins and configs we used before (if they're not included in antfu)
• cleaned up dependencies
• fixed most issues - those are not solved yet: I don't know/am unsure about how to fix. Can you check them?

Two questions:

1. Why did you remove the prettier plugin?
2. Does antfu check import sorting?

Only the promise plugin is missing eslint 9 support now, so I think we could merge this and enable the plugin later.

[anbraten]

• Why did you remove the prettier plugin?

Eslint by default does not have any stylistic rules anymore. Therefore it normally does not interfere with prettier.

• Does antfu check import sorting?

I wanted to start using @ianvs/prettier-plugin-sort-imports instead as its much faster with autosorting in ides.
