};

Example usage

Standalone mode

// server.js

var express = require('express'),
    minimist = require('minimist');

var options = minimist(process.argv.slice(2)),
    environment = options.environment || options.e || 'staging';

var lorry = require('lorry')(environment);

lorry.build();

if (!process.env.NODE_ENV || process.env.NODE_ENV === 'development') {
  lorry.watch(true);
}

var app = express();

app.set('port', (process.env.PORT || lorry.config.devPort));

app.use('/assets', express.static(path.join(__dirname, lorry.config.buildDirectory, lorry.config.assetOutputPath), {
  fallthrough: false
}));

app.get('*', function(request, response) {
  response.render('index.html', lorry.locals;
});

app.listen(app.get('port'), function() {
  console.log('Node app is running on port', app.get('port'));
});

Gulp mode

// gulpfile.js

var minimist = require('minimist');

var options = minimist(process.argv.slice(2)),
    environment = options.environment || options.e || 'staging';

var lorry = require('lorry')(environment, config);

lorry.installTask('build');
lorry.installTask('server');
lorry.installTask('deploy');

lorry.setDefaultTask('server');

Command-line switches

--remote / -r
# Build for remote execution
# This option is automatically set to true when running the "deploy" task or when NODE_ENV is set to something other than "development"

Command-line arguments

The following arguments will override values specified in the config object

--environment / -e
# Environment to use for build and deploy tasks
# This can be an environment key from the environments object, or the path to a file that contains a complete environment object.
# For an example, see the "Development environment" section below.

--host / -h
# Development server hostname

--port / -p
# Development server port number

Development environment

To use a custom environment for development, create a gitignored file (i.e. development.json) and pass this filename to gulp as the --environment argument.

File-based environments have the special property base, which specifies that this environment should extend an environment from the environments object with the given name. An example file-based environment is below.

{
  "base": "production",

  "dependencies": {
    "javascripts": [
      "//sdk.boxxspring.com/angularjs-boxxspring-sdk-2.0.10.js",
      "//localhost:8081/theme-boxxspring-sdk-1.13.0.js"
   ]
  }
}

Notes

lorry is designed to work with the Source Version Buildpack for Heroku, or a similar buildpack that sets the SOURCE_VERSION environment variable in profile.d. This value is used to build asset paths that include a query string for cache busting.
