✨ Astris

Build at the speed of light.

A modern, type-safe, and blazingly fast fullstack framework built 100% on Bun.

About

Astris is a fullstack framework built from the ground up on Bun. It combines automatic file-based routing, type-safe APIs, SSR + SPA hydration, and the ability to deploy as a native binary — all with zero configuration.

Features:

• 🚀 Blazingly fast (built on Bun, not Node.js)
• 📁 File-based routing (intuitive and automatic)
• 🔐 Fully type-safe (extracted from route definitions)
• 🎯 Zero configuration (works out of the box)
• 💾 SSR + SPA (server-side rendering with client hydration)
• 🐍 Deploy as native binary (single executable)

Installation

Node.js 18.0.0 or newer is required.

bunx @astris/cli init my-app
cd my-app
bun install
bun run dev

Example Usage

Create a page

// src/routes/page.tsx
export default function Home() {
  return <h1>Welcome to Astris</h1>
}

Create an API route

// src/routes/api/hello/route.ts
export interface HelloResponse {
  message: string
}

export async function GET(): Promise<Response> {
  return Response.json({ message: 'Hello from Astris!' })
}

Dynamic routes

// src/routes/users/[id]/page.tsx
export default function User({ params }: { params: { id: string } }) {
  return <h1>User {params.id}</h1>
}
