class-to-hooks

React class components are refactored to functional components by mapping this.state to useState, lifecycle methods like componentDidMount to useEffect, instance methods to useCallback, and refs to useRef. This reduces technical debt and improves code maintainability.

Mapping componentDidUpdate to useEffect dependency arrays involves translating previous props and state comparisons into array values. The conversion process handles these complex scenarios to ensure the hook triggers accurately when the tracked dependencies change.

Error boundaries cannot be refactored using hooks. Error boundaries require specific class component lifecycle methods that functional components cannot replicate, so the refactoring process flags these unconvertible patterns rather than attempting an automatic translation.

Handling contextType when converting to hooks requires mapping it to useContext. This replaces the static class property with a direct hook call inside the functional component, ensuring proper re-renders when the React context value changes.

Instance methods translate to standard functions or useCallback when converting React class to hooks. Using useCallback is necessary where the method is passed as a prop to child components, preventing unnecessary re-renders by maintaining referential equality across renders.

Yes, this component conversion supports TypeScript React codebases. It handles both JavaScript and TypeScript refactoring to leverage functional components and hooks, making older codebases easier to work with and test while transforming legacy class patterns.
