TriFrost is a blazing-fast, runtime-agnostic server framework built for the modern JavaScript ecosystem — from low-latency edge environments to traditional backend infrastructure.
Whether you're deploying to Node.js, Bun, Cloudflare Workers, or uWebSockets.js, TriFrost provides a unified API and internal architecture that adapts to the runtime — without compromising on performance, developer experience, or clarity.
TriFrost is the result of deep experience across frameworks, runtimes, and production systems. It combines:
- 🧩 Koa-like composability: build with middleware that’s small, explicit, and powerful
- ⚡ uWS-level performance: thanks to tight internal control over routing, context, and async flows
- 🌐 Edge-native philosophy: designed from the ground up to support Cloudflare Workers, and other emerging runtimes
- 🧠 Observability-first design: tracing is not an afterthought; it’s a core design concern with built-in support for structured telemetry
Unlike many frameworks, TriFrost doesn't bind itself to Node-specific APIs or assume a single deployment model. It’s truly runtime-flexible, letting you write code once and run it almost anywhere.
Using your favorite package manager:
# bun
bun add @trifrost/core
# npm
npm install @trifrost/core
# pnpm
pnpm add @trifrost/core
# yarn
yarn add @trifrost/coreTriFrost is guided by a few key beliefs:
- No magic. Ever. You should be able to trace exactly how data flows and how handlers resolve.
- Lean by default. We ship zero dependencies that aren’t critical to the core behavior.
- Typed end-to-end. First-class TypeScript support with generics and inference deeply embedded.
- Adaptable internals. Routing, context, and state management are designed to be both composable and overridable.
TriFrost is under active development as we build toward a solid v1.0 milestone.
The internal architecture is already production-grade, but APIs may still evolve as we polish developer ergonomics, refine edge-case behaviors, and finalize DX across runtimes.
