node.js - AngularJs/Nodejs updating view and animating it -

i'm writing

angularjs/nodejs

i useed $http service load data database , ngrepeat directive display view. can't when add new item database, update view 1 item, , animation.i know need use nganiamte , set class on ng enter how push single item data array without reloading whole view?

data load , insert

 vm.loaddata = function () {                          $http.get('/data')                               .success(function (data) {                                    vm.data = data;                               })                               .error(function (data) {                                    console.log('error: ' + data);                               });                     }             http.post('/data', data).success(function (data) {                 }) 

i assume vm.data array? should not reassign complete array rather add new items it, delete old items and/or update items in it. can add new items vm.data.push() , add/delete items vm.data.splice(). this, need compare vm.data data determine items need added/deleted/modified.
