Ember On Modifier

Overview:

The ember-on-modifier is an essential tool for developers working with Ember.js, particularly when it comes to managing event listeners in a more efficient and clean manner. Specified by RFC #471, this polyfill enhances the usage of the {{on}} element modifier, allowing for improved event handling in the Ember environment. It's specifically designed for those using ember-source version 3.11 or higher, having been tested against previous versions to ensure compatibility.

This modifier not only simplifies event listener management but also provides features such as automatic teardown of listeners when components are torn down and re-registration based on parameter changes. This makes it an invaluable addition to any Ember application, significantly improving both performance and ease of use for developers.

Features:

• Automatic Listener Management: The {{on}} modifier automatically removes event listeners when the element is no longer in the DOM, preventing potential memory leaks.
• Supports Multiple Events: You can apply the {{on}} modifier multiple times to the same element, allowing for numerous event listeners to be registered seamlessly.
• Flexible Event Options: Named parameters can be passed to addEventListener as options, granting you control over aspects like once, capture, and passive.
• IE11 Compatibility: A built-in ponyfill ensures that even Internet Explorer 11 users can utilize the modifier without facing functionality issues.
• Event Prevention Control: The ability to call methods such as preventDefault and stopPropagation allows for precise control over event behaviors directly within your application logic.
• Currying Support: Utilize the {{fn}} helper for currying function calls or partially applying arguments easily.
• Complementary Helpers: The ember-on-helper provides additional utility for adding event listeners to global objects like document and window.
