# Mounting Routes

The authentication routes must be mounted to your project. This gem includes a route helper for this purpose:

`mount_devise_token_auth_for` - similar to `devise_for`, this method is used to append the routes necessary for user authentication. This method accepts the following arguments:

| Argument     | Type   | Default      | Description                                                                                                                                                     |
| ------------ | ------ | ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `class_name` | string | 'User'       | The name of the class to use for authentication. This class must include the [model concern described here](/devise-token-auth/usage/routes.md#model-concerns). |
| `options`    | object | {at: 'auth'} | The [routes to be used for authentication](/devise-token-auth/usage/routes.md#usage) will be prefixed by the path specified in the `at` param of this object.   |

**Example**:

```ruby
# config/routes.rb
mount_devise_token_auth_for 'User', at: 'auth'
```

Any model class can be used, but the class will need to include [`DeviseTokenAuth::Concerns::User`](/devise-token-auth/usage/model_concerns.md) for authentication to work properly.

You can mount this engine to any route that you like. `/auth` is used by default to conform with the defaults of the [ng-token-auth](https://github.com/lynndylanhurley/ng-token-auth) module and the [jToker](https://github.com/lynndylanhurley/j-toker) plugin.
