Alert component - native alert and ionic alert

Ionic Framework ionic-v3
1

Hey,

I would like to create an alert component which displays a native alert on devices and ionic alert on browsers.
Do you guys have an idea how to do that?
The idea is to use it with promises.

Thanks

You could use condition and create alert by this. But why you need it? Why not use ionic alert?

I would like to do that due to this issue https://github.com/driftyco/ionic/issues/6224 that won’t be fixed.

Here is the class I’d like to use:

import {NavController} from "ionic-angular/index";
import {Platform} from "ionic-angular/index";
import {Dialogs} from "ionic-native/dist/index";
import {Alert} from "ionic-angular/index";

export interface AlertOption {
  message: string;
  title?: string;
  buttonName?: string;
}

export class Alert {
  private _useNativeComponent:boolean = true;


  constructor(private nav:NavController, private platform:Platform) {
    this._useNativeComponent = platform.is('cordova');
  }

  /**
   *
   * @param option
   * @returns {Promise<any>}
   */
  create(option?:AlertOption):Promise<any> {

    option.title = option.title || 'Alert';
    option.buttonName = option.buttonName || 'OK';

    if (this._useNativeComponent) {
      return this.createNative(option.message, option.title, option.buttonName);
    }
    else {
      return this.createIonic(option.message, option.title, option.buttonName);
    }


  }

  private  createNative(message, title, buttonName):Promise<any> {
    return Dialogs.alert(message, title, buttonName);
  }

  private  createIonic(message, title, buttonName):Promise<any> {
    return new Promise<any>(resolve=> {
      let alert = Alert.create({
        title: title,
        message: message,
        buttons: [{
          text: buttonName,
          handler: data=> {
            resolve();
          }
        }]
      });

      this.nav.present(alert);
    });
  }
}

But I don’t know how to instantiate the class once and use it everywhere I want to, like the ionic’s Alert
