Deploy

The easiest way to build your app is using the Grinder build system. Redstone.dart provides a simple task to properly copy the server’s files to the build folder, which you can use to create a build script.

Note: Since v0.5.18, Redstone.dart uses a new version of Grinder (v0.6.x), which includes some breaking changes. Also, with this new version, it’s possible to invoke the build script using the pub run command.

Creating a build script

Create a grind.dart file inside the tool folder

Redstone.dart v0.5.18 or above

import 'package:grinder/grinder.dart';
import 'package:redstone/tasks.dart';

main(List<String> args) {
  task('build', Pub.build);
  task('deploy_server', deployServer, ['build']);
  task('all', null, ['build', 'deploy_server']);

  startGrinder(args);
}

Redstone.dart v0.5.17 or below

import 'package:grinder/grinder.dart';
import 'package:grinder/grinder_utils.dart';
import 'package:redstone/tasks.dart';

main(List<String> args) {
  defineTask('build', taskFunction: (GrinderContext ctx) => new PubTools().build(ctx));
  defineTask('deploy_server', taskFunction: deployServer, depends: ['build']);
  defineTask('all', depends: ['build', 'deploy_server']);
  
  startGrinder(args);
}

Running the build script through DartEditor

To run grind.dart through Dart Editor, you need to create a command-line launch configuration, with the following parameters:

Running the build script through command line

Redstone.dart v0.5.18 or above

Just use the pub run command to invoke the build script (your pubspec.yaml file needs to include a dependency to the grinder package):

$ pub run grinder:grind all

If you install Grinder using pub global, you can invoke grind directly:

$ grind all

Redstone.dart v0.5.17 or below

To run grind.dart through command line, you need to set the DART_SDK environment variable:

$ export DART_SDK=(path to dart-sdk)
$ dart tool/grind.dart all

DartVoid

If you plan to deploy your app at DartVoid, you won’t need a build script, since DartVoid will manage the deploy for you.

DartVoid already provides a set of app templates built with several frameworks, including Redstone.dart, which you can use to bootstrap your app:

• Hello World
• Guestbook
• Todo List

Heroku

You can easily deploy Dart applications to Heroku, using the new cedar-14 stack, and the Dart buildpack. You can see a working example here.
