# Hapi


## Quick Start

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


## Critical Rules

1. **Compose with decorations & methods** - Expose services via [decorations](reference/server/decorations.md) and reusable logic via [methods](reference/server/methods.md)
2. **Follow the lifecycle** - 24-step request flow; see [lifecycle overview](reference/lifecycle/overview.md)
3. **Auth is three layers** - scheme → strategy → default; see [server auth](reference/server/auth.md)
4. **Validate at the route** - Use joi schemas on params, query, payload, headers; see [validation](reference/route/validation.md)
5. **Type routes with Refs** - Use `ServerRoute<Refs>` pattern; see [route scaffold](reference/typescript/route-scaffold.md)


## Workflow

1. **Create server** - [server overview](reference/server/overview.md) for constructor options
2. **Register plugins** - [plugins](reference/server/plugins.md) and [plugin structure](reference/plugins/overview.md)
3. **Configure auth** - [auth schemes](reference/server/auth.md) and [route auth](reference/route/auth.md)
4. **Define routes** - [route overview](reference/route/overview.md) with [handlers](reference/route/handler.md)
5. **Add extensions** - [lifecycle hooks](reference/server/extensions.md) and [pre-handlers](reference/route/pre.md)
