Where to keep utility functions in angular2 that are available in templates
I have a few simple "pure" utility functions in my app which i want to keep in one place. The problem is, i can import them in my components by using:
import { utilities } from '../shared/utilities'
However these utility function/methods are not available in my template files (because they are bound to the component class only). I have to create an alias of these functions in my component in order to use them. Is there a better way to do this?
I think you should be able to use the utilities in the template if you inject it in your controller. Something like this :
import { Utilities } from './shared/utils';
@Component({
....
....
})
export class ExampleComponent {
constructor(public util: Utilities) { }
}
In your template you should be able to use util.your_function
Update:
export class ExampleComponent {
constructor(public util: Utilities) { }
get staticMethod1() { return Utilities.staticMethod1(); }
}
