In this new v1.11.1 we ran a 217 (passing) tests for performance, reliability and security.

Why Engineers Choose Jetpath

Every framework promises to be fast and simple but they are not.

// This is a complete API endpoint in Jetpath
export const GET_users_$id: JetRoute = async function (ctx) {
  const { id } = ctx.params;
  const user = await db.users.findUnique({ where: { id } });
  return ctx.send(user);
};

Jetpath eliminates the cognitive overhead that slows down development in many ways, you only write functions that map directly to HTTP endpoints through a clean, predictable naming convention.

The tech stack you already trust, but faster:

• Write APIs in TypeScript/JavaScript across Node.js, Deno, or Bun
• ~25% less code than Express with stronger type safety
• Benchmarks show massive throughput compared to Elysia.js *(bunJS fastest Framework).

Core Design Principles

Jetpath is built with strong opinions on what matters to you:

1. Zero config by default
2. Runtime agnostic - True support for Node.js, Deno, and Bun, AWS Lambda and cloudflare workers.
3. Type safety
4. Predictable routing - Routes derived from function names *(GET_users_$id → GET /users/:id)
5. Built for production
6. Faster iteraction

Quick Start

# Create new project

npx jetpath new-project

# Navigate and start the dev server

cd new-project
npm install 
npm run dev

API Design That makes everything simple and concise

import { type JetRoute, Jetpath, use } from "jetpath";

const app = new Jetpath();
app.listen(3000);

// GET /products
export const GET_products: JetRoute = async (ctx) => {
  const products = await db.products.findMany();
  ctx.send({ products });
};

// POST /products with validation
export const POST_products: JetRoute = async (ctx) => {
  const data = await ctx.parse();
  const product = await db.products.create({ data });
  ctx.send({ product }, 201);
};

// Add validation and docs in one step
use(POST_products)
  .title("Create a new product")
  .body((t) => ({
    name: t.string().required().min(3),
    price: t.number().required().min(0),
    description: t.string()
  }));

// Maps to ws://your-host/live instantly
export const GET_live: JetRoute = (ctx) => {
  ctx.upgrade();
  const conn = ctx.connection!;
  conn.addEventListener("open", (socket) => { /* ... */ });
  conn.addEventListener("message", (socket, event) => { /* ... */ });
};

Real Performance

It's not just a claim how fast - measure it. In the benchmark suite, Jetpath consistently perform close to raw Bunjs performance and matches elysia.js on common API workloads:

12-core CPU, 32gb Ram, 1000 concurrent connections and 1,000,000 requests, simple JSON response

Bunjs being amongst the fastest http runtime.
