Mapping changes need republish

[ynzenu]

Whenever anything needs to be changed/added/removed a republish has to be done of the entire project. That's why we need a config file where the mapping will be defined. Only that config file then has to get updated when anything changes.

The custom config file will contain property mapping as well as settings like the access token and database ids for the models. (last 2 are available in version 1.0.3)
