I'm about to design my Web service API, most of the functions of my API is basically very simular to my web application.
Now the question is, should I create 1 single method and reuse them for both the web application and the web service api? (This seems to be the logical solution, however its very complicated; it's much easier to duplicate the method used by the web application, and keep both separate, ie one method for the web application and one method for the web service.)
How do you guys do it?
1) REUSE: one main method and reuse them for both web application and web service application (I like this but it's complicated)
WebAppMethodX --uses--
COMMONFUNCTIONMETHOD_X
APIMethodX ---uses----
COMMONFUNCTIONMETHOD_X
ie common function performs functions such as creating/updating/deleting records etc
2) DUPLICATE: two methods, one method for the web application and one method for the web service.
WebAppMethodX
APIMethodX
