Upgrading to ESLint 9

[jolindroth]

First, thank you guys for amazing work.

This boilerplate is using the deprecated ESLint 8 - causing red warnings at build-time.

Do you have any plans to migrate to ESLint 9?

Hey @jolindroth, thank you for reporting this. We are using expo eslint as our base rules, and it seems they do not yet support the latest version (v9). Therefore, we will likely wait for the Expo team to upgrade before transitioning to v9.

For now, we will switch this to a discussion, and we hope to tackle it very soon.

expo/expo#28144
expo/expo#34653
expo/expo#34653

Seems support for v9 is coming very soon!

Hey! Just a question. I see that, running expo doctor is recommending the following version of eslint-config-expo:

{
    packageName: 'eslint-config-expo',
    packageType: 'devDependencies',
    expectedVersionOrRange: '~8.0.1',
    actualVersion: '7.1.2'
}

But in the project, we are ignoring this package. Why are we excluding this package from the expo doctor checks?

@jolindroth, that's correct. We attempted to migrate to the latest version, but we encountered some issues with other rules. We will update them when the new version, which works correctly with v9, is ready.
