How to config different development environment in Angular 2 app

Question

I have a constant file

export class constants {
    public static get API_ENDPOINT(): string { return 'https://dvelopment-server/'; }
}

And I imported it to my service

private _registrationUrl = constants.API_ENDPOINT+'api/v1/register';

How can I change the endpont with server change . I have development server staging server and local server. I want app to detect the environment change.

In my angular 1 app I used envserviceprovider for this. Can I use the same in angular 2 app ?

I have solved the issue by adding a class method

export class config {

    public static getEnvironmentVariable(value) {
        var environment:string;
        var data = {};
        environment = window.location.hostname;
        switch (environment) {
            case'localhost':
                data = {
                    endPoint: 'https://dev.xxxxx.com/'
                };
                break;
             case 'uat.server.com':
                data = {
                    endPoint: 'https://uat.xxxxx.com/'
                };
                break;

            default:
                data = {
                    endPoint: 'https://dev.xxxx.com/'
                };
        }
        return data[value];
    }
}

In my service

private _loginUrl = config.getEnvironmentVariable('endPoint')+'api/v1/login;
