How to define constant in one file and access in another file in angularjs

Question

I am handling many variable in my application, I dont want to define the string each and every time. Instead of that I want to access the string from one file and access through all the files in my application.

Eg:

one = 1;

I want to access 1 with the variable name one in my application, because in future it can be changed as one (one = one) that time I cant change in all the place.

In order to avoid such difficulty am going for the constant file.

You can create a service and access it in any controller by injecting it.

angular.module('app')
.constant('CONSTANTS', {something: 12});

your controller

angular.module('app').controller('mainCtrl', function (CONSTANTS) {              
    $scope.mainctrlvariable = CONSTANTS.something;
});

your another controller

angular.module('app').controller('otherCtrl', function (CONSTANTS) {              
        $scope.otherCtrlvariable = CONSTANTS.something;
    });

yes, you can add more and more constants to the hash.... {something: 12, one:1, more: 20, two: 13}.

Angular provides constants and values services, that may help you

'use strict';
angular
    .module('App', [])
    .constant("config", {
        one:1,
        two:2
    })
    .config(function () { })
    .controller('MainCtrl', function (config) {
        console.log(config.one)
    });
