It's not something easy since it's internally handled by the CustomHammerGesturesPlugin class. I see two approaches:
Provide your own Hammer plugin and register it. When the
Hammer
object is instantiated, you need to provide your configuration as second parameter:@Injectable() export class CustomHammerGesturesPlugin extends HammerGesturesPlugin { addEventListener(element: HTMLElement, eventName: string, handler: Function): Function { var zone = this.manager.getZone(); eventName = eventName.toLowerCase(); return zone.runOutsideAngular(function() { // Creating the manager bind events, must be done outside of angular var mc = new Hammer(element); // <------- mc.get('pinch').set({enable: true}); mc.get('rotate').set({enable: true}); var handler = function(eventObj) { zone.run(function() { handler(eventObj); }); }; mc.on(eventName, handler); return () => { mc.off(eventName, handler); }; }); } }
Since the
HammerGesturesPlugin
provider is automatically register when using thebootstrap
function, you need to use this code to bootstrap your application (see https://github.com/angular/angular/blob/master/modules/angular2/platform/browser.ts#L110 and https://github.com/angular/angular/blob/master/modules/angular2/src/platform/browser_common.ts#L79):platform(BROWSER_PROVIDERS).application(appProviders).bootstrap(appComponentType);
A workaround could be to intercept the instantiation of the
Hammer
object (see Can I intercept a function called directly?Can I intercept a function called directly?):<script> window.TargetHammer = window.Hammer; window.Hammer = function() { var mc = new TargetHammer(arguments[0]); mc.get('press').set({ time: 1000 }); return mc; } </script>

Otherwise I don't know which version of Angular2 you use but there is a problem with Hammer events (beta.0 seems to be okay):
