Class to Functional — React Migration

Scope: Migrating class components to function components with hooks. All mappings sourced from CockroachDB's production codebase migration skill. Does NOT cover general hook patterns (SKILL.md) or performance optimization (Performance.md).

Core Mappings

• this.state = { ... } → individual useState hooks — one hook per logical piece of state, not one object. [source: cockroachdb/cockroach]
• componentDidMount → useEffect(fn, []) — empty deps array runs once after first render. [source: cockroachdb/cockroach]
• componentDidUpdate(prevProps, prevState) → useEffect(fn, [deps]) — list the specific values that should trigger the effect. [source: cockroachdb/cockroach]
• componentWillUnmount → cleanup return from useEffect — return a function; React calls it on unmount. [source: cockroachdb/cockroach]
