Top tip for receiving a JSON response object using AngularJS

I am currently working with an API that returns a json array object. In my Controller, I have been able to retrieve the json data successfully using the following code:

angular.module('lyricsApp', [])
.controller('LyricsController', ['$scope', 'ApiCall', function ($scope, ApiCall) {
    $scope.lyrics = {
        id: "",
        songName: "",
        singerName: "",
        writtenBy: "",
        lyricText: "",
        isEnable: "",
        created_at: "",
        updated_at: ""
    };

    $scope.searchLyric = function () {
        var result = ApiCall.GetApiCall().success(function (lyrics) {
            $scope.lyrics.id = lyrics.data.id
            $scope.lyrics.singerName = lyrics.data.singerName;
            $scope.lyrics.songName = lyrics.data.songName;
            $scope.lyrics.writtenBy = lyrics.data.writtenBy;
            $scope.lyrics.lyricText = lyrics.data.lyricText;
            $scope.lyrics.isEnable = lyrics.data.isEnable;
            $scope.lyrics.created_at = lyrics.data.created_at;
            $scope.lyrics.updated_at = lyrics.data.updated_at;   
        });
    }
}])

However, I believe there might be a more efficient way to handle this. I tried the following approach:

var result = ApiCall.GetApiCall().success(function (lyrics) {
     $scope.lyrics=lyrics.data;
});

But in this scenario, I encountered an issue where certain values were returning undefined:

console.log($scope.lyrics.id); // shows Undefined

If anyone has suggestions on how to improve this process, I would greatly appreciate it.

It's great that you're on the right track, just be cautious with using console.log too early. If the log statement runs before the assignment, it may return an undefined value.

I'm not sure why you opted for var result =.

You can simplify it like this:

ApiCall.GetApiCall('v1', 'lyrics', '1').success(function (data) {
    $scope.lyrics = data.data;
    console.log($scope.lyrics.id);
}).error(function(data){
    console.log(data);
});
