The Angular AoT build failed

[egorermolaev]

When I try to build my project with the "--prod" flag (for iOS and Android) there's a following error.

Running app-scripts build: --prod --platform android --target cordova [10:32:32] build prod started ... [10:32:32] clean started ... [10:32:32] clean finished in 2 ms [10:32:32] copy started ...

Sup man,

No idea how to solve it. My solution was not to use all-swipe plugin…

When installing the package via npm, you'll see that in your node_modules/ionic-swipe-all/module.js that there is the following:

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { IonicSwipeAll } from './ionic.swipe.all';
var IonicSwipeAllModule = (function () {
    function IonicSwipeAllModule() {
    }
    IonicSwipeAllModule.decorators = [
        { type: NgModule, args: [{
                    declarations: [IonicSwipeAll],
                    exports: [IonicSwipeAll],
                    imports: [CommonModule],
                },] },
    ];
    /** @nocollapse */
    IonicSwipeAllModule.ctorParameters = function () { return []; };
    return IonicSwipeAllModule;
}());
export { IonicSwipeAllModule };
//# sourceMappingURL=module.js.map

which I assume is the cause of the issue.

To fix this, I simply created my own directive to mimc the functionality

npm install hammerjs --save && npm install @types/hammerjs --save-dev

# I'm using Ionic
ionic generate directive swipe-all

import { Directive, ElementRef, EventEmitter, OnInit, Output } from '@angular/core';

import { HammerGestureConfig } from '@angular/platform-browser';

import * as Hammer from 'hammerjs';

@Directive({
  selector: '[swipe-all]' // Attribute selector
})
export class SwipeAllDirective extends HammerGestureConfig implements OnInit {

  @Output() swipe = new EventEmitter<any>();
  @Output() swipeup = new EventEmitter<any>();
  @Output() swipedown = new EventEmitter<any>();

  private hammer: any = Hammer;

  constructor(private elem: ElementRef) {
    super();
  }

  ngOnInit(): void {
    const instance = new Hammer(this.elem.nativeElement);
    instance.get('swipe').set({ direction: this.hammer.DIRECTION_ALL });

    instance.on('swipe', event => this.swipe.emit(event));
    instance.on('swipeup', event => this.swipeup.emit(event));
    instance.on('swipedown', event => this.swipedown.emit(event));
  }
}

Then include it in your app modules and use it <div swipe-all (swipedown)="...">...

I think the npm version needs to be repackaged

@timmyomahony I followed your steps and created a new directive, but the event is fired twice every time I swipe my finger on the screen. Do you know what could be causing that behaviour?

Edit: Strangely, removing completely the directive and just leaving the methods works. I would say that Hammerjs is somehow already implemented in Ionic

Hi guys, sorry for the delay, I'm been really busy.

@egorermolaev @mipatel2811 @mayankprayas I made a few changes in settings to work with prod builds. Can you please test again with new 1.3.0 version?

@diegokiaranet In fact the swipe event fired twice for the (swipeup) and (swipedown), I've already fix this, feel free to test new version.

Thank you all.
