Gesture Ionic 4



First of all, I think you need to add a category for ionic-v4 for the forum.

Secondly, we are working on to migrate Ionic 3 app into Ionic 4. We use (tap) in Ionic 3. In Ionic 4, it doesn’t work and also, I don’t see gesture under components in Ionic 4 documentation. Will gestures be included in Ionic 4? Or do we need to replace all (tap) with (click)?

Thank you!



Gesture is present in Core. Maybe just not documented yet

Ionic is the designated category for latest Ionic release (4). Somewhere published by moderator in this forum


I was able to get it working by using

import { GestureController } from ‘@ionic/core/dist/collection/utils/gesture/gesture-controller’;

and instead of new Gesture(element);
use new GestureController(element);


Below is the html I have for the tap event

<ion-button (tap)="processCameraOption()">
  {{ buttonText }}

I saw the following warning on the console
The “tap” event cannot be bound because Hammer.JS is not loaded and no custom loader has been specified.


@ankeetas I replaced all “(tap)” with “tappable (click)”


Thank you @lancevo! I will try that.


Can you give a usage example with GestureController? Like, when we want to capture “pan” or something else?


@gravityaddiction Can you please share a example. This would be very great. thx a lot
