fastify-best-practices

What problem does it solve?

This skill provides guidance on Fastify best practices, focusing on plugin architecture, encapsulation, and composition to help you build maintainable, scalable Node.js backends with Fastify.

Core Features & Use Cases

• Encapsulation and plugin-based architecture: every plugin runs in its own isolated context, enabling safe composition and reuse.
• Decorators, hooks, and registration patterns: best practices for decorators, lifecycle hooks, and plugin loading orders (including @fastify/autoload usage).
• Testing and project structure guidance: how to organize plugins by feature and test them in isolation, with realistic scenarios like building user and admin features.

Quick Start

Create a new Fastify application, implement a small encapsulated plugin with a route (e.g., GET /ping), and register it in the main app to observe encapsulation behavior.
