manifest.json

Any module needs the manifest.json file. The file should be located in the module's primary directory (ui/modules/module_name/manifest.json).

As a bare minimum, manifest.json should specify these fields:

{
           "manifest_version": 2.0,
           "id": "my_ip_address",
           "name": "My IP Address",
           "namespace": "MyIPAddress",
           "version": "1.0"
       }
