Angular 2: How to check if running app using "ng serve"

Issue

Is there any sort of flag or global node variable available that tells you whether or not you are using ng serve to run Angular?

Need this for development purposes, just need a flag of some sort.

Solution

import { isDevMode } from '@angular/core';

...

if(isDevMode()) { ...

https://angular.io/api/core/isDevMode

might work for you, but it doesn't actually tell if it is served by ng serve
