Ellie Mae Scripting Framework Guest Library (EM-SSF)
Interactions thru the EM-SSF always start by instantiating the scripting object and retrieving a published object from the host, e.g.
import emssf from '@elliemae/em-ssf-guest' var hostObject = await emssf.getObject("<object_name>");
Once an object is retrieved, you can call its publicly exposed methods to interact with the host application. Note that each host application will expose a different set of objects, so consult the documentation for the appropriate product to learn more about the published objects.
