Hapi

Quick Start

const server = Hapi.server({ port: 3000 });
server.route({ method: 'GET', path: '/', handler: () => 'ok' });

Critical Rules

1. Compose with decorations & methods - Expose services via decorations and reusable logic via methods
2. Follow the lifecycle - 24-step request flow; see lifecycle overview
3. Auth is three layers - scheme → strategy → default; see server auth
4. Validate at the route - Use joi schemas on params, query, payload, headers; see validation
5. Type routes with Refs - Use ServerRoute<Refs> with ONLY the keys you need (Params, Query, Payload, etc.); omitted keys keep defaults. See route scaffold
