> Did you mean /config/environment.js ?

Yup sorry, typo. Would look something like this:

```auto
if (environment === 'mirage') {
  // enable mirage
  ENV['ember-cli-mirage'].enabled = true;
}

```

Just need to enable mirage. Could also turn on mirage logging (`ENV['ember-cli-mirage'].logging = true`) or whatever else you wanted.

> Where did you define this mixin ?

See “Create authenticated route mixin” in my answer [here](https://discuss.emberjs.com/t/how-to-use-esa-or-esat-to-authenticate-against-custom-provider/14142/5)

> Or are they just to be replaced by some fake values ?

Exactly, they can be anything since it’s all fake and mirage won’t be checking your token
