  1. Fastify is built around JSON schema validation, making it an excellent choice for validating data efficiently at scale.
  2. Define and validate incoming request bodies, query parameters, headers, and cookies using JSON schemas.
  3. Fastify automatically validates data against the schemas before hitting route handlers, ensuring data integrity.

Tip: Utilize the fastify-ajv plugin to easily extend validation with custom formats or complex rules.

  • One of the most impressive features of Fastify is that it automatically generates JSON schema definitions from route handlers.
  • Use route-specific schemas for request and response validation that Fastify will automatically generate into OpenAPI or JSON Schema documentation. Use the auto-generation of schema to enhance your API documentation without having to write it manually.

Tip: Use fastify-oas or fastify-swagger to generate and expose OpenAPI/Swagger documentation from your schemas.

  • Native support is available with Fastify regarding HTTP2; therefore, all applications get to enjoy new performance features out-of-the-box.
  • Enable HTTP2 support using multiplexing and enhanced header compression. Use server push and multiple streams, which can also reduce latency and make a page load faster. The tip to enable HTTP2 is the fastify-http2 plugin, and thus ensure your application is friendly to that protocol for smoother usage.

  • Fastify is built to focus on performance with support for compressors like fastify-compress, in which the payloads of its responses are compressed efficiently.
  • Automatically compress responses, with Brotli or gzip or deflate, as an optimization over bandwidth.
  • It supports a heavily optimized compression algorithm that enables the least use of CPU as it serves the compressed contents.

Tip: Set the conditional compression, depending upon the type of response such that large asset files and videos do not get needlessly compressed.

  • Fastify offers a very powerful lifecycle hook system that controls the flow of requests at several stages, which means that it is highly customizable.
  • Use onRequest, preHandler, onResponse, etc., to inject logic before or after some events (like logging, authentication, or validation).
  • Fastify's hooks help to process things efficiently by supporting lightweight middleware mechanisms tied to particular stages of request handling.

Tip: Use onRequest to validate or transform request data before it hits the route handler and onResponse for post-processing after route execution.

  • Fastify has an automatic error-handling system that works smoothly with its schema-based validation.
  • If validation fails for a route, Fastify automatically returns a detailed error message in a standardized format without the need for custom error handling logic.
  • Customize error handling for application-specific errors or to enhance the response format for consumers.

Tip: Customize error messages using the setErrorHandler function to ensure consistent error responses across your API.

  • Fastify's core is built around the non-blocking, asynchronous nature of Node.js, which provides a huge performance boost.
  • Every operation, from HTTP requests to database queries, should be asynchronous to keep the event loop unblocked.
  • Fastify's optimizations around async/await syntax ensures that I/O operations run efficiently without bottlenecks.

Tip: Use async route handlers for better performance, especially when dealing with high concurrency in production environments

  • Fastify provides a very low overhead for JSON response serialization compared to other frameworks.
  • Fastify serializes JSON responses using a highly optimized library, which makes it faster and reduces memory usage.
  • The framework minimizes the cost of response serialization, which is particularly useful when dealing with high-volume data.

Tip: Enable fast-json-stringify for even faster serialization when working with large datasets or complex objects.

  • Fastify is optimized for handling a large number of requests per second with minimal overhead.
  • Take advantage of the framework's built-in support for hooks to process requests asynchronously and in parallel, improving throughput.
  • Implement preValidation hooks for checking requests before validation, allowing custom pre-processing like caching or token validation.

Tip: Leverage preValidation hooks to perform expensive or frequently accessed data checks in parallel, reducing response times.

  • Fastify is built around a powerful plugin system that makes it easy to integrate and enhance functionality without bloating your application.
  • Fastify's plugin system allows you to extend core functionality in a consistent, reusable manner.
  • Use the plugin ecosystem to integrate with authentication systems, database connectors, caching layers, and more.

Tip: Isolate third-party integrations (e.g., databases, APIs) into separate plugins for a cleaner codebase and easier maintenance.

  • Fastify supports graceful shutdown out of the box; this means that before closing the application, it can close the connections and perform the necessary cleanup.
  • To gracefully close the server, use the fastify.close() method. This ensures all outstanding requests are completed before the app shuts down. Fastify supports clean shutdowns, including handling ongoing requests, closing database connections, and handling in-flight data correctly.

Tip: Combine graceful shutdown with process management tools like PM2 or Docker to make sure fault tolerance and deployment downtime are kept at bay.

  • Fastify allows real-time communication using WebSockets with minimal configuration.
  • Use the fastify-websocket plugin to introduce real-time, bi-directional communication in your applications.
  • Fastify integrates seamlessly with WebSocket connections for applications like chat, live updates, or notifications.

Tip: Leverage Redis to manage pub/sub messaging across multiple instances by integrating WebSocket connections.
