Release Notes

facebook/react (eslint-plugin-react-hooks)

v6.1.1

Compare Source

Note: 6.1.0 accidentally allowed use of recommended without flat config, causing errors when used with ESLint v9's defineConfig() helper. This has been fixed in 6.1.1.

• Fix recommended config for flat config compatibility. The recommended config has been converted to flat config format. Non-flat config users should use recommended-legacy instead. (@​poteto in #​34700)
• Add recommended-latest and recommended-latest-legacy configs that include React Compiler rules. (@​poteto in #​34675)
• Remove unused NoUnusedOptOutDirectives rule. (@​poteto in #​34703)
• Remove hermes-parser and dependency. (@​poteto in #​34719)
• Remove @babel/plugin-proposal-private-methods dependency. (@​ArnaudBarre and @​josephsavona in #​34715)
• Update for Zod v3/v4 compatibility. (@​kolian and @​josephsavona in #​34717)

v6.1.0

Compare Source

Note: Version 6.0.0 was mistakenly released and immediately deprecated and untagged on npm. This is the first official 6.x major release and includes breaking changes.

• Breaking: Require Node.js 18 or newer. (@​michaelfaith in #​32458)
• Breaking: Flat config is now the default recommended preset. Legacy config moved to recommended-legacy. (@​michaelfaith in #​32457)
• New Violations: Disallow calling use within try/catch blocks. (@​poteto in #​34040)
• New Violations: Disallow calling useEffectEvent functions in arbitrary closures. (@​jbrown215 in #​33544)
• Handle React.useEffect in addition to useEffect in rules-of-hooks. (@​Ayc0 in #​34076)
• Added react-hooks settings config option that to accept additionalEffectHooks that are used across exhaustive-deps and rules-of-hooks rules. (@​jbrown215) in #​34497

Accidentally released. See 6.1.0 for the actual changes.

Needs Review

I recommend reviewing this upgrade before merging because it introduces two critical breaking changes: a Node.js version requirement bump to v18+ and a migration from legacy ESLint config to flat config format. While this project already uses ESLint flat config (eslint.config.mjs), the plugin now defaults to 'recommended' instead of 'recommended-legacy', and the codebase imports the plugin directly without using any recommended preset configuration. Additionally, there's a reported issue with v6.x unexpectedly installing 37 Babel dependencies even for projects not using Babel, which could significantly bloat the dependency tree. Manual review is needed to verify Node.js compatibility, confirm the flat config setup works correctly with the new default, and assess the impact of the Babel dependency bloat.

What we checked

• eslint-plugin-react-hooks upgraded to 6.1.0 which requires Node.js 18+ and changes default config preset ^[1]
• Plugin registered manually in flat config without using recommended preset - needs verification that this approach still works correctly with v6.x breaking changes ^[2]
• Project uses ESLint flat config format which is required for v6.x compatibility ^[3]
• Version 6.x installs 37 additional Babel dependencies even for projects not using Babel or React compiler, significantly bloating dependency tree ^[4]
• Official migration guide documents flat config changes and new preset naming (recommended vs recommended-legacy) ^[5]

Dependency Usage

This dependency is a development tool used exclusively within the eslint-config-fuf package to enforce React Hooks linting rules. It is integrated into the React ESLint configuration preset exported by this package, enabling projects that consume this configuration to automatically validate proper usage of React Hooks patterns (such as ensuring hooks are called in the correct order and only within function components). The plugin operates as part of the code quality infrastructure rather than supporting direct business functionality, providing automated developer guardrails during the development process.

Changes

BREAKING: eslint-plugin-react-hooks now requires Node.js 18+ and switches to flat config as the default recommended preset (legacy config moved to recommended-legacy). The update adds stricter rules for use hooks in try/catch blocks and useEffectEvent in closures, while fixing false positives in components with do/while loops.
