Chump - Pushover.net client for Node.js
Chump is a client for the popular Pushover.net real-time
notification service.
Use Chump to send Android, iOS, watchOS, and desktop notifications.
Chump makes full use of Pushover.net's API.
Installation
Chump was written for Node.js 4+.
npm install --save chump
Basic Usage
It is easy to send messages via Pushover.net using Chump.
Sending Messages
let chump = require('chump');
let client = new chump.Client('yourApiToken');
let user = new chump.User('userIdHere', 'optionalUserDeviceHere');
let message = new chump.Message({
title: 'Example title',
message: 'Example message',
enableHtml: false,
user: user,
url: 'http://example.org',
urlTitle: 'Example.org',
priority: new chump.Priority('low'),
sound: new chump.Sound('magic')
});
client.sendMessage(message)
.then(() => {
console.log('Message sent.');
})
.catch(error => {
console.log('An error occurred.');
console.log(error.stack);
});
All client methods that send a command return a Promise.
Sending Messages With Emergency Priority
An emergency priority can be attached to a message. This requires that the
message is acknowledged by the user, and can renotify the user on failure to
acknowledge. Pushover.net can also call an optional callback URL after the user
acknowledges the message. A message receipt is returned to the resolved Promise
on successful delivery of emergency priority messages.
let priority = new chump.Priority('emergency', {
retry: 300,
expire: 3600,
callback: 'http://example.org'
});
let message = new chump.Message({
title: 'Example emergency',
message: 'Super important message',
user: user,
priority: priority
});
client.sendMessage(message)
.then(receipt => {
console.log(`Message sent. Receipt is ${receipt}`);
});
Advanced Usage
Chump supports the entire Pushover.net API. The client offers convenience methods
that correspond to each Pushover.net endpoint.
As documented earlier, all client methods that send a command return a Promise.
.verifyUser
Verify that a user (and optionally, the user's device) exists on Pushover.net
let user = new chump.user('userIdHere', 'optionalUserDeviceHere');
client.verifyUser(user)
.then(() => {
console.log('User exists.');
})
.catch(error => {
console.log('User may not exist.');
console.log(error.stack);
});
.getReceipt
Additional receipt information can be retrieved from Pushover.net. Receipts are
only returned for messages sent with an emergency priority.
client.getReceipt(receipt)
.then(receipt => {
console.log(`Receipt: ${receipt.id}`);
console.log(`Acknowledged: ${receipt.isAcknowledged}`);
console.log(`Acknowledged by: ${receipt.acknowledgedBy}`);
console.log(`Last delivered at: ${receipt.lastDeliveredAt}`);
console.log(`Is expired: ${receipt.isExpired}`);
console.log(`Expires at: ${receipt.expiresAt}`);
console.log(`Has called back: ${receipt.hasCalledBack}`);
console.log(`Called back at: ${receipt.calledBackAt}`);
});
.cancelEmergency
A message with an emergency priority can be cancelled.
client.cancelEmergency(receipt);
.getGroupDetails
Pushover.net supports managing users within groups. Creating groups can only be
done through Pushover.net's website. Assuming you know the group Id, you can use
Chump to retrieve information for the group from Pushover.net.
let group = new chump.Group(groupId);
client.getGroupDetails(group)
.then(group => {
console.log(`Group name: ${group.name}`);
for (let user of group.users) {
console.log(`User: ${user.id}, ${user.device}`);
}
});
.addUserToGroup
Add a user to a known group.
let user = new chump.User(userId);
let group = new chump.Group(groupId);
client.addUserToGroup(user, group);
.removeUserFromGroup
Remove a user from a known group.
let user = new chump.User(userId);
let group = new chump.Group(groupId);
client.removeUserFromGroup(user, group);
.enableGroupUser
Enable a user in a known group.
let user = new chump.User(userId);
let group = new chump.Group(groupId);
client.enableGroupUser(user, group);
.disableGroupUser
Disable a user in a known group.
let user = new chump.User(userId);
let group = new chump.Group(groupId);
client.disableGroupUser(user, group);
.renameGroup
Rename a known group.
let group = new chump.Group(groupId);
client.renameGroup(group, 'New name');
Track Application Limitations
Pushover.net limits the number of messages emitted from its service. Chump keeps
track of these limitations after each successful message sent. You can access app
limitations from the following client properties:
let appLimit = client.appLimit;
let appRemaining = client.appRemaining;
let appReset = client.appReset;
