Problem :

Sometime the configuration Script may take some big seconds to complete (provisionning by webserviceAPI calls, git commands, etc..). During this time, the user has an empty componant or a componant filled with previous state.

It should be interesting to have a setUp script which is call before the "regular" Script.
Usually this script will return a defaut "waiting" value.
The purpose of this, is to alert the user that something is building in background.

Another possible implementation can be to disable the component during the build.
