Angular Modules vs ES6 Modules - DZone Web Dev

<img src="/img/2017/03/angularicon1.png" alt=""> In this post, you’ll find a quick tutorial explaining the difference between Angular Module and ESG Modules, and how to best use each of these platforms.

Here is a quick summary:

ES6 Module Example:

import { sqrt } from 'math-utils';

const addition = (val1, val2) => val1 + val2;
const subtraction = (val1, val2) => val1 - val2;
const multiplication = (val1, val2) => val1 * val2;
const calculateSquareRoot = (val) => sqrt(val);

export { addition, multiplication }

Angular Module Example:

@NgModule({
imports: [ BrowserModule, HttpModule, FormsModule ],
declarations: [ PersonComponent, ContactComponent, ContactListComponent ],
providers: [ PersonService, ContactService ],
exports: [ ContactListComponent, ContactComponent ]
})

export class ContactModule {}
