An Angular. It was derived from the Angular Hammer project by Monospaced. Add hmTouchEvents to your app or module's dependencies. This module is designed to work with Angular. Angular Hammer uses the semantic version naming convention major. The major version will only change when the major version of Hammer. Changes to minor should be thought of as possibly breaking, though typically they will be breaking changes to the API i.

Changes to patch should be thought of as bug fixes or small feature additions that may require changing or adding HTML attribute values.

At this time Angular Hammer has been tested with both Angular. I reserve the right to change my mind once the v2. The hmTouchEvents module provides a series of attribute directives for hooking into the standard Hammer.

Events on the top level are fired every time a gesture of that type happens. The second-level events are more specific to the gesture state i. Behaviors to be executed on an event are defined as values of the attribute. This value is parsed as an Angular expression.

Beware, invalid Angular expressions will throw an Angular error with those terrible call stacks. Each element that responds to Hammer events contains it's own managerwhich keeps track of the various gesture recognizers attached to that element. Angular Hammer does not make use of the standard Hammer constructorinstead instantiating an empty manager and adding only the required recognizers.

However, if you were to add the same series of directives to an element, the default behavior would be the same as if they had been instantiated using the Hammer constructor.

The behavior of any manager can be customized using the hmManagerOptions attribute. This attribute value should be a stringified JSON Object that has one or more of the properties listed below. If you choose to set the cssProps option, lease make sure that you are using the properties listed in the Hammer Documentation. If you define the preventGhosts property, that value will be attributed to all recognizers associated with that manager.

Gesture recognizers are responsible for linking events and handlers. Each element has a manager that maintains a list of these recognizers. Hammer defines some default behavior for each type of recognizer see the links in the table belowbut that behavior can be customized using the hmRecognizerOptions attribute. Recognizer options objects may have any of the properties listed in the table below, a checkmark in a column means that either Hammer or Angular Hammer denoted AH will make use of this option when instantiating the recognizer.

A couple of things to be aware of:. You can add custom gesture recognizers using the hmCustom directive. Custom gestures are defined using the hmRecognizerOptions attribute. You can define a single custom gesture using an object, or a series of custom gestures using an array of objects. However, only a single handler, set as the value of the hmCustom attribute, will be triggered when any of these custom gestures are recognized.

When defining a custom gesture, the recognizer options object must have a value for the type and event properties. The behavior that is executed when this gesture is recognized is the value of this attribute. Currently as of v2. This decision was made to unify the use of the hmManagerOptions and hmRecognizerOptionsbut may be changed in future versions to support multiple behavior handlers.

The type property is used to determine which base type of gesture recognizer to modify. The event property is the name of the gesture as well as the name of the only event that Hammer will fire when it recognizes this gesture.

Do not mix custom and standard gesture recognizers attributes in a single element as the behaviors will be in conflict. Angular Hammer v2.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It will listen for the actions using the NgRx ActionsSubject. This Subject is notified for every action that is dispatched in NgRx. Subscribing only to the actions I care about in a given component. Note that I am going to the first recipe once the user tries to swipe left nextRecipe called on the last recipe.
