export class constants {

}

Answer 1

I would just like to add put some more light into the answer provided by @Cartucho. He is right about the steps required to setup a personalized environment for your angular 2 apps. I would also like to second the opinion that the article at Guide to Build the app in different environments

But the given article misses out on an important step. Steps to set up a personalized environment are as follows: 1) Create a new file called environment.YourEnvName.ts in the environments folder in the project. 2) Add the Environment description in the "environments" object in the angular-cli.json file.

"environments": {
    "source": "environments/environment.ts",
    "prod": "environments/environment.prod.ts",
    "dev": "environments/environment.dev.ts", 
    "qa": "environments/environment.qa.ts",
    "YourEnvName": "environments/environment.YourEnvName.ts"
  }

3) Once you have made these changes you can build the app for your new environment using the following command.

ng build --environment=YourEnvName or 

ng serve --environment=YourEnvName 

Hope this post is helpful to any new Angular 2 developer.
