Case conversion

The case conversion middleware can map from a specific text notation to another text notation. This way your code doesn’t need to follow the same text notation as the JSON API exposes.

$mapper = (new \JsonMapper\JsonMapperFactory())->default();

# Add the middleware to convert from studly caps to camel case
$mapper->push(new \JsonMapper\Middleware\CaseConversion(

$object = new \Tests\JsonMapper\Implementation\SimpleObject();
$mapper->mapObject(json_decode('{ "Name": "John Doe" }'), $object);

echo $object->getName(); // "John Doe"

The case conversion middleware currently supports the following text notations:

  • Studly caps
  • Camel case
  • Underscore
  • Kebab case
