By default, the exported JSON keys mirror the class names. If you want to camelize class names (useful in JS), pass the query parameter `camelCase` to css-loader.

#### Possible Options

|Option|Description|
|:----:|:--------|
|**`true`**|Class names will be camelized|
|**`'dashes'`**|Only dashes in class names will be camelized|
|**`'only'`** |Class names will be camelized, the original class name will be removed from the locals|
|**`'dashesOnly'`**|Dashes in class names will be camelized, the original class name will be removed from the locals|
