angularjs - Where should my (angular) data-manipulation logic go when polling for data -


i'm working on first large(ish)-scale angular project.

i have angular service polls , returns json data web-service every 5 seconds.

this data structured this:

- top level   - category     - item       - details       - ... more details     - item       - ...   - category 2     - item       ...

when polling, categories remain constant, items added on hits webservice.

in many cases displaying "items" category, other times collecting items , filtering them details.

what cleanest way approach kind of thing. i've considered few approaches, not sure best.

  • using filters ({{toplevel | allitems | filter:... }})
  • having service expose different configurations of data using different $scope variables.
  • just putting login in controller , exposing different data configurations different scope variables

any thoughts / advice / suggested resources appreciated

when i've done similar things, modify data within controller. i'll have couple functions format data in desired ways. store them within same $scope variable. 

$scope.data - {     categories: {...},     allitems: {...},     byid: {...} }

then within view event can used switch way it's being organized. assume work well, depends on how data have, & how you're polling, etc.
