ember-tick-tock

Installation

• ember install ember-tick-tock

About

This Ember-CLI add-on provides a ticktock service that will keep the current time synced in your application. In any component/controller/model/etc you can inject the service with the following line:

ticktock: Ember.inject.service()

Then, you will have access to the current time (a Moment.js object) by accessing the now computed property in the service

isExpired: Ember.computed('expiresAt', 'ticktock.now', function() {
  return this.get('expiresAt') <= this.get('ticktock.now');
}

Options

For some applications, when you cannot rely on the end-user's clock, you may need to use a remote endpoint to get the current time. You can pass an options object in your applications config/environment.js file.

ENV['ticktockOptions'] = {
  tickTockFrequency: 1,
  useRemoteTimestamp: true,
  remoteSyncFrequency: 60,
  timestampEndpoint: ENV.apiServer + '/timestamp',
  timestampProperty: 'time'
};

• tickTockFrequency: (Default: 1) How often (in seconds) should timestamp be updated
• useRemoteTimestamp: (Default: false) Let the service know to sync with a server
• remoteSyncFrequency: (Default: 60) How often to ping the server (in seconds) to get an updated timestamp
  • The service will still update the now property every second, regardless of this value
• timestampEndpoint: (Required if useRemoteTimestamp is true) The URL to make a GET request to that will return an object that contains a timestamp
• timestampProperty: (Required if useRemoteTimestamp is true) The name of the property in the object returned by timestampEndpoint
