Deploy

Spry is designed to be cross-platform, this chapter will guide you on how to deploy on other runtimes.

Below, we will use a file named server.dart as a demonstration, its content is:

import 'package:spry/spry.dart';

Future<void> main() async {
  final app = createSpry();

  app.all('/', (_) => '🎉 Welcome to Spry!');
  app.get('/say/:name', (event) {
    return 'Your name is ${event.params['name']}';
  });

  final server = app.serve(port: 3000);
  await server.ready();

  print('🎉 Spry Server listen on ${server.url}');
}

Dart VM

By default, in Dart VM you must compile and deploy, just run the following command:

dart run server.dart

Native (Binary Executable)

You can directly run the following command to compile it into a native binary executable:

dart compile exe server.dart -o server

If you have a specific target OS, you can add the --target-os parameter:

dart compile exe server.dart -o server --target-os [Your target OS]

For example, macOS:

dart compile exe server.dart -o server --target-os macos

JavaScript runtime

Currently, Spry supports Node.js, Deno, and Bun JavaScript runtimes.

We use the following command to transpile server.dart to server.js:

dart compile js server.dart -o server.js

It will automatically recognize the runtime platform internally, you just need to run it:

Bun

bun run server.js

Node.js

node server.js

Deno

deno run --allow-net server.js
