My challenge lies in utilizing the isPropertyUpdated function within Angular 4. However, I have encountered a roadblock as Angular 4 does not facilitate deep imports.
An example of an import that fails to work on Angular 4 is:
import {isPropertyUpdated} from 'angular2/src/common/forms/directives/shared'
Given this limitation, how can I successfully integrate isPropertyUpdated in my Angular 4 project?
If you find yourself in need of this information, consider delving into the source code to determine if it aligns with your specific requirements. In most cases, utilizing ngOnChanges() should suffice.
To implement this in your project, include the following snippet:
import { elooseIdentical } from '@angular/core';
export function isPropertyUpdated(changes: {[key: string]: any}, viewModel: any): boolean {
if (!changes.hasOwnProperty('model')) return false;
const change = changes['model'];
if (change.isFirstChange()) return true;
return !elooseIdentical(viewModel, change.currentValue);
}
