MoonBack

MoonBack is an asynchronous web backend framework for MoonBit. It provides routing, middleware, typed request and response helpers, WebSocket upgrades, graceful shutdown, and module-scoped dependency injection.

MoonBack is a pre-1.0 project. The core APIs are usable, but compatibility may change between minor releases. Packages under middlewares/unstable_* are explicitly experimental.

Install

Add MoonBack to your moon.mod:

import {
  "moonbitlang/async@0.21.0",
  "moonbitlang/moonback@0.8.2",
}

preferred_target = "native"

Migrating from hackwaly/moonback

Starting with version 0.8.2, MoonBack is published as moonbitlang/moonback. Replace the old dependency in moon.mod:

import {
  "moonbitlang/moonback@0.8.2",
}

Application source code can continue to use the @moonback package alias. If you import an experimental middleware directly, update its full package path from hackwaly/moonback/middlewares/... to moonbitlang/moonback/middlewares/... as well.

Quick start

async fn main {
  let app = @moonback.App(ctx => {
    ctx.get("/", (_req, res) => res.send_text("Hello, MoonBack!"))
  })
  defer app.close()

  let server = @moonback.listen(port=3000)
  app.serve(server)
}

See the full guide for routing, requests, responses, WebSockets, middleware, dependency injection, configuration, and lifecycle management.
