taxum

taxum is a composable and type-safe HTTP framework for Node.js, heavily inspired by Rust's Axum and Tower. It brings the same declarative, middleware-driven architecture to the JavaScript/TypeScript ecosystem, combining ergonomic route composition with deep integration of the type system.

Written entirely in TypeScript, Taxum focuses on zero-cost abstractions, strong compile-time guarantees, and predictable request handling. Its design emphasizes modularity and composability, building on principles proven in the Rust ecosystem and adapting them to the asynchronous, event-driven nature of Node.js.

Features

• Composable middleware: Tower-style middleware model for building reusable logic layers.
• Type safety first: TypeScript-first design ensures that request parameters, bodies, and responses are all statically typed.
• Functional and declarative routing: Build routes as data structures, not strings — inspired by Axum's handler model.
• Performance-aware: Minimal overhead, predictable execution — ideal for high-performance APIs and backend services.
• First-class testing ergonomics: Easy integration with testing tools, request injection, and handler isolation.
