Answer
Use dependency injection, configuration-driven module loading, versioned modules, and isolated service layers for modular design.
Quick Answer
Plugin-based architecture: define a plugin interface (a function that receives app context and registers routes/services), load plugins at startup from a directory or config, use dependency injection so plugins don't import each other directly. Fastify has a native plugin system with encapsulation. This keeps the core small and features composable.
