winterspec v0.0.96

☃️ winterspec

!NOTE This project is a fork of the awesome work of the Seam team in the original edgespec module. Please check them out and use the Seam API!

WinterSpec is an opinionated HTTP framework for TypeScript. Out of the box, it:

• Uses filepath-based routing
• Soon generates ergonomic SDKs across multiple languages
• Soon generates OpenAPI documentation
• Provides end-to-end type safety for your middleware and endpoints
• Can be built into a zero-dependency module and embedded into other applications

WinterSpec primarily targets the common minimum API described by WinterCG, but it can also target Node.js, Bun, and Deno. Currently, the two main "edge"/WinterCG-compatible platforms targeted are Cloudflare Workers and Vercel Edge Functions.

Regardless of your target, WinterSpec provides a consistent API and encourages emulation of the WinterCG runtime when developing.

Getting Started

To start a new project:

npm create winterspec@latest # [soon]

npm run dev

Usage

• Routes ⭐
• Bun/Node Usage, Test Fixturing
• Middleware
• Global route config
• Code generation (typings & OpenAPI)
• WinterSpec config
• Bundling & deployment 🚀
• Embedding as a module
• Programmatic usage

Alternatives

WinterSpec may not be the right choice for your project. This list is not exhaustive, but here are some alternatives:

• If your backend and frontend are tightly coupled:
  • Next.js with React Server Components
  • Remix
  • Express or Fastify with tRPC
• If you dislike filepath-based routing and need to run within a WinterCG-compatible environment:
  • Hono (with or without tRPC)
• If you enjoy dependency injection:
  • NestJS
• If your project is mainly frontend with a few API routes:
  • Next.js
