Introduction to Jetpath

Write Once, Run Cross-runtime

Jetpath is more than just another framework - it’s your new best friend in backend development, designed to make your life easier while giving you unprecedented flexibility.

What Makes Jetpath Special?

• Write Once, Run Cross-runtime: Your code runs seamlessly on Node.js, Deno, or Bun. No more worrying about runtime lock-in!
• Zero-Router Magic: Create endpoints by simply writing functions. No need to wrestle with complex routing and middleware.
• TypeScript First: Built with TypeScript from the ground up, giving you the best of both worlds: type safety and JavaScript flexibility.
• No boring parts: We’ve eliminated all the boring parts of backend development so you can focus on what matters - building amazing features.

How It Works

Jetpath uses smart conventions and naming-based routing. Instead of writing route definitions, you just:

1. Create .jet.ts or .jet.js files in your src directory

2. Export functions with intuitive names like METHOD_ + optional path segments

3. That it.

For example, create src/users.jet.ts with:

import { type JetRoute } from "jetpath";
// This becomes GET /users
export const GET_users: JetRoute = (ctx) => {
  ctx.send({ message: "runs on any runtime!" });
};

It’s that simple!

Here the best parts of Jetpath

• 🚀 Blazing Fast Development: No more configuration files or complex setup. Just write your code and let Jetpath handle the rest.
• 📚 Automatic API Docs: Define your validation schemas once, and get beautiful, interactive API documentation that stays in sync with your code.
• 🔒 Type Safety: Built with TypeScript first, giving you the best of both worlds: type safety and JavaScript flexibility.
• 🧩 Unlimited Extensibility: Extend Jetpath with official plugins or create your own. The framework is designed to grow with your needs.
• 💡 Smart Conventions: Jetpath works the way you think. Function naming conventions means your code structure matches your API structure.

Jetpath is perfect for:

• Every Developer & Teams: Build projects faster without sacrificing quality
• Startups: Rapidly iterate on your API while maintaining type safety
• Enterprise Teams: Build maintainable, scalable APIs that work across multiple runtimes
• Full-Stack Developers: Finally have a backend framework that matches the joy of frontend development
• Anyone Who Hates Boilerplate: Jetpath handles the boring stuff so you can focus on what matters
• Anyone Who Loves: Developer experience, code maintainability, and runtime flexibility
