fastify

To build a high-performance Node.js API, use Fastify with TypeScript to leverage JSON schema validation and type providers like Zod or TypeBox. This combination provides automatic request validation, response serialization, and type-safe routes for robust backend development.

The best way to validate API requests in a Fastify backend is using schema-driven development with JSON schema and type providers such as Zod or TypeBox. This approach automatically validates incoming data against predefined schemas and ensures type safety.

Yes, you can use Fastify's plugin architecture to organize Node.js API routes into encapsulated plugins. This modular design improves code maintainability and testability by separating concerns and scoping plugin functionality effectively.

You can test Fastify API routes in memory by utilizing the framework's built-in `inject` method. This feature allows you to perform efficient and isolated route testing by simulating HTTP requests directly within your test environment.

To secure a Node.js API using Fastify, implement security hardening measures like CORS, Helmet, and rate limiting. These protections help secure backend operations and defend against unauthorized access and abusive traffic.
