fastify-domain-delivery

What problem does it solve?

It prevents Fastify implementations from drifting into unstructured, schema-inconsistent behavior by turning API changes into plugin-safe, schema-first, lifecycle-aware deliveries with scoped verification.

Core Features & Use Cases

• Schema-first route contracts: Defines params, query, body, and response schemas up front to keep runtime validation and output shape aligned.
• Plugin encapsulation and lifecycle correctness: Ensures decorators are registered before use, external resources are opened/closed in the owning plugin, and lifecycle phases are respected.
• Operationally visible verification: Plans and tests the smallest fastify.inject slice to prove auth hooks, serializers, async error mapping, and shutdown behavior without binding a real port.
• Error, hook, and observability rigor: Routes async errors through typed errors and a registered error handler, applies hooks at the narrowest lifecycle scope, and instruments request/trace/metrics fields when safe.

Quick Start

Ask your AI tool to apply the Fastify domain delivery flow to your specific feature by requesting a schema-first implementation plan with the exact plugin boundary and a scoped fastify.inject verification command.
