Ember CLI Mirage is a great addition to your development arsenal. It allows you to develop your application’s API needs before the back-end team finishes their stack.

Install ember-cli-mirage from your terminal to start using it:

ember install ember-cli-mirage

Next, to turn Mirage on and off, add an environment variable to config/environment.js:

if (environment === 'development') {
  // ENV.APP.LOG_RESOLVER = true;
  // ENV.APP.LOG_ACTIVE_GENERATION = true;
  // ENV.APP.LOG_TRANSITIONS = true;
  // ENV.APP.LOG_TRANSITIONS_INTERNAL = true;
  // ENV.APP.LOG_VIEW_LOOKUPS = true;
  ENV['ember-cli-mirage'] = {
    enabled: true
  }
}

Finally, add fake data in the form of factories for your witness and cryptid endpoints.

To work with your Tracker app, you can retrieve a configured app/mirage directory from the supplied example assets in Tracker/Data_Chapter/mirage-example. We will keep the example up to date for current releases of the addon.
