ESLint v10.0.0 introduces breaking changes requiring Node.js v20.19+, v22.13+, or v24+. The old eslintrc configuration format is no longer supported; users must migrate to eslint.config.js. Configuration file lookup now starts from each linted file's directory rather than the current working directory. JSX references are now properly tracked for scope analysis. The eslint:recommended preset enables three new rules. Several deprecated APIs, methods, and rule options have been removed, including context methods like getCwd() and getSourceCode(), and SourceCode methods like getJSDocComment(). The stylish formatter now uses Node.js's native styleText instead of chalk. Plugin developers must update custom rules to use property-based context members and handle JSX identifiers in scope analysis.

Migrate to v10.x

I’ve moved to <a href="https://biomejs.dev/" target="_blank" rel="noopener nofollow">Biome</a> after many years with ESLINT and it is great, highly recommended

Moved to oxlint, it’s still a bit rough but happy overall. eslint was the worst piece of crap left in my tech stack

Unsubscribe. Performance is insufficient, and I’m knee deep in testing faster alternatives. Eslint, thanks for everything, now we must part.

For some reason I thought ESLint was already at v10 🤷🏻‍♂️
But it’s always good to have updates.
I have also moved on to Biome for formatting. And yeah it’s really fast 🚀
