Node.js wrapper to send notification to Android devices using Google Cloud Messaging service.
npm install node-gcm-service
The only thing you need is a google server api key. For more information go to GCM getting started guide.
Require the module
var gcm = require('node-gcm-service');
Create a message object with default values and set all variables after, or with another object:
var message = new gcm.Message();
// set data with another object
message.setDataWithObject({
key1: 'value1'
});
// add new key-value to data if key does not exists
message.addDataWithKeyValue('key2','value2');
// set collapse key
message.setCollapseKey('string');
// set dry run
message.setDryRun(false);
// set delay while idle
message.setDelayWhileIdle(true);
var message = new gcm.Message({
collapse_key: 'test',
data: {
key1: 'value1'
},
delay_while_idle: true,
time_to_live: 34,
dry_run: false
});
Create a sender object with default values and set the api key after, or with another object:
var sender = new gcm.Sender();
// set api key
sender.setAPIKey('key');
var sender = new gcm.Sender({
key: 'my_api_key'
});
Important : you can set the endpoint and end path URLs if Google change these URLs
And finally send the message to the specified registration id(s) with retries or not, in JSON format or plain-text format :
sender.sendMessage(message.toJSON(), registration_ids, true, function(err, data) {
if (!err) {
// do something
} else {
// handle error
}
});
sender.sendMessage(message.toString(), registration_ids, false, function(err, data) {
if (!err) {
// do something
} else {
// handle error
}
});
