You should leave Mirage installed (and a folder on disk), but shut down the server whenever you want to use your actual backend API. This will allow using Mirage in a selective environment, for example, during testing.
By default, Mirage is disabled in production as well as in development when using the -proxy option.
To disable Mirage explicitly, you can set the enabled config parameter to false . For example, to always disable in development:
// config/environment.js ... if (environment === 'development') { ENV['ember-cli-mirage'] = { enabled: false }; }
