Ember Is Fastboot
This addon provides a mixin to make it easy to know if your addon is currently in FastBoot mode. This approach is lovingly stolen from a great PR made by @tylerturdenpants!


ember install ember-is-fastboot


The is-fastboot mixin is the only utility you need to use! It provides an _isFastBoot computed that tells you if FastBoot mode is currently active.
For example, if you have a service that needs to short-circuit some logic in FastBoot:
// services/foo.js
import Service from '@ember/service';
import IsFastbootMixin from 'ember-is-fastboot/mixins/is-fastboot';

export default Service.extend(IsFastbootMixin, {
  doStuff() {
    if (this.get('_isFastBoot')) {
      return; // Don't do the stuff, we're in FastBoot mode
    // Do the stuff, we're not in FastBoot mode

That's it! You can throw this mixin into any Ember object that needs to be FastBoot-aware.
