Package Exports
- dbus-native
- dbus-native/lib/constants
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (dbus-native) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
node-dbus
D-bus protocol client and server for node.js
Installation
Important: install socat
to be able to use session bus.
npm install dbus-native
or
git clone https://github.com/sidorares/node-dbus # clone the repo
cd node-dbus
npm install # install dependencies
sudo cp examples/com.github.sidorares.dbus.Example.conf /etc/dbus-1/system.d/ # if you want to test examples/service.js
Usage
Short example using desktop notifications service
var dbus = require('dbus-native');
var sessionBus = dbus.sessionBus();
sessionBus.getService('org.freedesktop.Notifications').getInterface(
'/org/freedesktop/Notifications',
'org.freedesktop.Notifications', function(err, notifications) {
// dbus signals are EventEmitter events
notifications.on('ActionInvoked', function() {
console.log('ActionInvoked', arguments);
});
notifications.on('NotificationClosed', function() {
console.log('NotificationClosed', arguments);
});
notifications.Notify('exampl', 0, '', 'summary 3', 'new message text', ['xxx yyy', 'test2', 'test3', 'test4'], [], 5, function(err, id) {
//setTimeout(function() { n.CloseNotification(id, console.log); }, 4000);
});
});
API
Low level messaging: bus connection
connection = dbus.createClient(options)
options:
- socket - unix socket path
- port - TCP port
- host - TCP host
- busAddress - encoded bus address. Default is
DBUS_SESSION_BUS_ADDRESS
environment variable. See http://dbus.freedesktop.org/doc/dbus-specification.html#addresses - ( TODO: add/document option to use adress from X11 session )
connection has only one method, message(msg)
message fields:
- type - methodCall, methodReturn, error or signal
- path - object path
- interface
- destination
- sender
- member
- serial
- signature
- body
- errorName
- replySerial
connection signals:
- connect - emitted after successful authentication
- message
- error
example:
var dbus = require('dbus-native');
var conn = dbus.createConnection();
conn.message({
path:'/org/freedesktop/DBus',
destination: 'org.freedesktop.DBus',
'interface': 'org.freedesktop.DBus',
member: 'Hello',
type: dbus.messageType.methodCall
});
conn.on('message', function(msg) { console.log(msg); });
