+This middleware checks for all empty inputs to all routes (unless used at a router level) by checking the **body** of both POST and GET requests.
+
+Note: 0 does count as a valid input.
+
+All empty inputs will be met with a **400** and the message: `{ msg: 'Some fields are missing!' }`.
+
+You can specify the middleware to skip the check for **GET** requests in the config option.
