Readme

ember-clock
This is an Ember-cli addon that provides a clock service. The clock synchronizes to the local host system clock and can be used to display the time or to update time sensitive properties.

Compatibility

2.x requires Ember 4+ and Node 18.18+

Breaking Changes in 2.0.0

v2.0.0 removes implicit injections as these are deprecated in Ember 3.x and removed in Ember 4.x. You must explicitly inject the clock service like so:
import Component from '@glimmer/component';
import { service } from '@ember/service';

export default class MyComponent extends Component {
  @service clock;
}

Installation

  • ember install ember-clock

ClockService

The clock service should be injected into controllers and components where required.
To use the clock in a template or in computed properties, bind to the clock's hour, minute, or second properties.
In templates:
{{this.clock.hour}}
{{this.clock.minute}}
{{this.clock.second}}

In computed properties:
@service clock;

get seconds() {
  // this will update every second
  const second = this.clock.second
  return `${ second } seconds`
});

Known Issues

The clock service will break Ember acceptance tests, as it creates a continuous run loop to update the current time. To disable the runloop update your config/environment file with the following
module.exports = function (environment) {
  //...
  if (environment === "test") {
    //...
    ENV["ember-clock"] = {
      disabled: true,
    };
  }
};
