Fastify is a high-performance web framework for Node.js that focuses on minimal overhead and predictable extensibility. It pairs a declarative routing API with JSON Schema–driven validation and serialization, so requests are checked at the edge and responses are produced quickly. The framework’s plugin system uses encapsulation to isolate routes, decorators, and hooks, which keeps large codebases modular and avoids accidental cross-pollution. Built-in hooks (such as onRequest, preHandler, and onSend) and lightweight decorators make it easy to insert cross-cutting concerns like auth, caching, and metrics. Fastify ships with thoughtful defaults like structured logging via Pino and AJV for schema validation, and it has first-class TypeScript types. The result is a server stack that scales to high throughput while remaining easy to reason about in production.

Fastify DX is an upcoming full stack framework built on top of Fastify and Vite. In this early stage, we're working to define a Universal Route Module API. Currently, only Fastify v3 is supported, v4 support is already in the works. Fastify DX is currently in alpha. Right now the focus is on implementing the same API for React, Vue, Solid and Svelte. A minimal zx-based CLI for enhanced Developer Experience is planned next. Subscribe to this newsletter to hear about the public beta.

Forms is a Node.js library designed to simplify the creation, validation, and handling of web forms on the server side, providing a structured approach to managing user input. It allows developers to define form schemas using a declarative API, specifying fields, validation rules, and data transformations in a consistent format. The library supports a wide range of input types, including text, numbers, dates, and custom fields, making it adaptable to different application needs. It includes built-in validation mechanisms that ensure user input meets specified constraints before being processed. Forms also provides utilities for rendering HTML form elements, reducing the need for manual template coding. It integrates with popular Node.js web frameworks, enabling seamless handling of form submissions and data processing. The design emphasizes reusability and maintainability, allowing developers to define forms once and use them across different parts of an application.
