Bun

BuildTarget.bun compiles your Spry application to a single JavaScript file optimised for the Bun runtime.

Config

import 'package:spry/config.dart';

void main() {
  defineSpryConfig(host: '127.0.0.1', port: 4100, target: BuildTarget.bun);
}

Build output

.spry/
  src/
    main.dart       ← compile input
  bun/
    index.js        ← compiled output, run directly with bun

Build and run

dart run spry build
bun .spry/bun/index.js

Production deployment

Copy .spry/bun/index.js and your public/ assets to the server. No Dart SDK or intermediate wrapper needed.

bun index.js

Good fit

• Bun-based self-hosting
• Teams already running Bun in production
• Deployments where startup time matters
