# grunt-open

Open urls and files from a grunt task

## Installation

Install using npm in the root of your project directory (where your package.json and Gruntfile.js are located)

```bash
npm install --save-dev grunt-open
```

## Usage

This is used as part of your grunt tasks, between the `server` and `watch` tasks

```js
grunt.registerTask('default', ['server', 'open', 'watch']);
```

You can specify different configurations so that you can set up task chains (see the configuration below for this example's config)

```js
grunt.registerTask('dev', ['server', 'open:dev', 'watch']);
grunt.registerTask('build', ['build', 'server', 'open:build', 'watch:build');
```

## Gruntfile Configuration

This is a very simple task and takes two configuration parameters, `path` (required) and `app` (optional). If `app` is not specified, the default system browser will be launched

```js
grunt.initConfig({
  open : {
    dev : {
      path: 'http://127.0.0.1:8888/src',
      app: 'Google Chrome'
    },
    build : {
      path : 'http://google.com/',
      app: 'Firefox'
    },
    file : {
      path : '/etc/hosts'
    },
    custom: {
      path : function () {
        return grunt.option('path');
      } 
    }
  }
})

grunt.loadNpmTasks('grunt-open');

```

## Options

#### openOn
Type: `String`

While it may not be common, you may want to delay the opening of your `path` at a later time of the grunt process. The option `openOn` allows you to define an event (coming through from [grunt.event](http://gruntjs.com/api/grunt.event)) that would signal the expected triggering of `open`. Example:

```js
grunt.initConfig({
  open: {
    delayed: {
      path: 'http://localhost:3000',
      app: 'Google Chrome',
      options: {
        openOn: 'serverListening'
      }
    }
  }
});

grunt.registerTask('server', function () {
  var server = require('myServer');
  server.listen(3000, function (err) {
    if (!err) {
      grunt.log.writeln('Server started');
      grunt.event.emit('serverListening'); // triggers open:delayed
    }
  });
})
```

#### delay
Type : `Number`

Set a delay for the open. *Note:* This task moves on immediately. If this is the last task in your chain you run the
risk of node exiting before your open is called.
