Growly

Simple zero-dependency Growl notifications using GNTP.

Installation

Install growly using npm:

npm install growly

And then require it:

var growly = require('growly');

This module uses the Growl Network Transport Protocol (GNTP) which was implemented in Growl since version 1.3, so you must have an appropriate version of Growl installed for Growly to work.

Example

Sending a minimal Growl notification:

var growly = require('growly');

growly.notify('This is as easy as it gets', { title: 'Hello, World!' });

More examples can be found in the example/ directory.

Usage

The growly module exposes only three methods: Growly.register(), Growly.notify(), and Growly.setHost().

Growly.register(appname, [appicon], [notifications], [callback])

Registers a new application with Growl. Registration is completely optional since it will be performed automatically for you with sensible defaults. Useful if you want your application, with its own icon and types of notifications, to show up in Growl's prefence panel.

appname the name of the application (required.)
appicon url, file path, or Buffer instance for an application icon image.
notifications a list of defined notification types with the following properties:
- .label name used to identify the type of notification being used (required.)
- .dispname name users will see in Growl's preference panel (defaults to .label.)
- .enabled whether or not notifications of this type are enabled (defaults to true.)
callback called when the registration completes; if registration fails, the first argument will be an Error object.

An example:

growly.register('My Application', 'path/to/icon.png', [
    { label: 'success', dispname: 'Success' },
    { label: 'warning', dispname: 'Warning', enabled: false }
], function(err) {
    console.log(err || 'Registration successful!');
});

Growly.notify(text, [opts], [callback])

Sends a Growl notification. If an application wasn't registered beforehand with growly.register(), a default application will automatically be registered beforesending the notification.

text the body of the notification.
opts an object with the following properties:
- .title title of the notification.
- .icon url, file path, or Buffer instance for the notification's icon.
- .sticky whether or not to sticky the notification (defaults to false.)
- .label type of notification to use (defaults to the first registered notification type.)
- .priority the priority of the notification from lowest (-2) to highest (2).
- .coalescingId replace/update the matching previous notification. May be ignored.
callback called when the user has closed/clicked the notification. The callback is passed an Error object err as the first argument when the notification fails; otherwise, the second argument action is a string that'll describe which action has been taken by the user (either 'closed' or 'clicked'.)

An example:

/* Assuming an application was registered with a notification type labeled 'warning'. */
growly.notify('Stuffs broken!', { label: 'warning' }, function(err, action) {
    console.log('Action:', action);
});

Growly.setHost(host, port)

Set the host and port that Growl (GNTP) requests will be sent to. Using this method is optional since GNTP defaults to using host 'localhost' and port 23053.
