How to update angularjs constant during run time?

Question

I have defined constant in my application as follows,

angular.module('configuration', [])
 .constant('Engine_API', 'http://sample.io:1929/')

And i am using in the application as follows,

var testApp = angular.module('Duot', [ 'configuration']
testApp .controller('userProfileCtrl', function ($scope,Engine_API) {
}

is there a way i can modify and set a new value to the constant in run time?

Kindof by definition, given that it is a constant, you cannot. — Ava

If you are looking for easy updatable central storage, consider using a value. .value('myData', { Engine_API: 'http://sample.io:1929/' }); You can then access and update myData.Engine_API as desired. — Lex

Why you not create a dataservice to share some general data? — Stephu

You can not change angular constant value. But if you want to change value, you can use angular value provider instead of constant.

angular.module('configuration', [])
 .value('Engine_API', 'http://sample.io:1929/')
