A curated set of rules and patterns for building production-ready Fastify applications. Each rule includes incorrect and correct examples with explanations.
The rules are organized by topic in the rules/ directory. Each rule follows a consistent format with impact rating, incorrect/correct examples, and references to official docs.
| Create Server | create-server.md | LOW-MEDIUM | Use a buildServer() factory function for reusable, testable server setup | | Create Plugin | create-plugin.md | LOW-MEDIUM | Encapsulate reusable functionality in plugins with fastify-plugin | | Autoload | autoload.md | HIGH | Automatically load plugins and routes from the filesystem with @fastify/autoload |
Apply Fastify best practices when creating servers, plugins, routes, schemas, hooks, decorators, error handling, testing, and TypeScript integration. Use when writing or reviewing Fastify code, setting up a new Fastify project, or asking "How should I structure my Fastify app?" Source: thecodepace/fastify-skills.
