    demo_update:
   path:         api/demo/photos/{uid}
   controller:   Vendor\Demo\Controller\DemoApiController::edit
   methods:      PUT
   requirements:
      uid:        \d+
   defaults:
      data:
   options:
      middleware:
         - auth

    Tip

    edit action has been already implemented in our predefined controller.

    PUT is not required, but as we follow the concept, we should always use it.

    requirements has uid argument and tells us it must be of type integer.

    data is required argument here, as we later pass data that will be placed inside data argument.

    auth FE user session is required as well as proper csrf token.

  2. Use defined above endpoint in JavaScript scope.

    ...

updateResource('/api/demo/photos/1', {title: 'Title 1'}).then(function (isOk) {
   console.log(isOk);
});

...

    Tip

    updateResource function has been already implemented in our predefined Routes.js.
