Below is a longer-winded way of asking if it makes sense to use a service
(or factory, rather) as a collection of resources from other services and
to maintain some kind of relationship status between these other services.
If that statement doesn't make sense on it's own, I cobbled together a
thought example below.
---
Let's say I have a service that handles a couple of http calls for a
collection of THINGS and THINGCATEGORIES. Something along these lines:
.factory('THINGS1', ['APIService',
function(APIService) {
var model = {};
model.THINGS = [];
model.THINGCATEGORIES = [];
APIService.getTHINGS().then(function(THINGS) {
model.THINGS = THINGS.data;
});
APIService.getTHINGCATEGORIES().then(function(CATS) {
model.THINGCATEGORIES = CATS.data;
});
return {
getCategories: function() {
return model.THINGCATEGORIES;
},
getThings: functino() {
return model.THINGS;
}
}
}])
And let's say I've got a number of these kinds of services and they relate
hierarchically somehow. A given page might need to know about
relationships between a few of these services and keep track of an active
state of some of these things. As an example, say SERVICE1 (THINGS1)
hierarchically dictates which THINGS2 in SERVICE2 are shown on a page. On
top of that, THINGS in SERVICE2 can be turned on an off through say a
directive, so someone needs to keep tabs of which THINGS2 in SERVICE2 are
active.
And, let's say this particular configuration happens in two different
pages, so I'd like to build it as reusably as possible. Would it make the
most sense to have a third service, say THINGCOLLECTIONSERVICE that pulls
in the THINGS from SERVICE1 and SERVICE2 and maintains the active states
for the page controllers?
Or would it be better to have the active states maintained in a
controller? My worry with that is that the controller might not be
strictly reusable in both pages where this is occurring.
Or I guess I could just throw and active state array in the individual
services?
Hopefully this makes sense.
