The request names 'react' and asks what to use for React 18 lifecycle patterns. None of the candidates is a React lifecycle guide itself; Sentry React 1 is the closest match with a React SDK and setup actions for error boundaries and monitoring, and AI SDK React 2 and LaunchDarkly React 3 provide React-related SDK/runtime tooling. Please specify what you need from React 18 lifecycles (e.g., error handling, data fetching, or observability) for a more precise answer.
A question back: Which React 18 lifecycle aspect do you need: error boundaries, effects and cleanup, data fetching, or observability?
