An ESLint (and Oxlint) plugin that detects unnecessary React useEffect calls based on React's 'You Might Not Need an Effect' guidance. It analyzes state, props, refs, and effect timing to flag redundant effects with actionable fixes.

Use cases

• catch unnecessary useEffect calls in React components
• lint derived state anti-patterns in React
• reduce redundant re-renders from effects
• teach new React developers the effects mental model
• enforce React hook best practices in CI
• find setState calls inside effects

When to choose

• you maintain a React codebase using hooks and want to eliminate redundant effects
• you want actionable lint rules with suggestions and documentation links
• you use ESLint flat config or legacy config, or Oxlint

When to avoid

• your project does not use React
• you need general-purpose React linting beyond effects (use eslint-plugin-react or react-hooks)
• you need runtime behavior analysis rather than static linting
