Learn Polymer, Tweenlite and Tweenmax

Polymer is a framework created at Google for building reusable web components.

We use HTML elements every day such as div, a, button, form, and table. All HTML elements provide some sort of API of attributes, properties, methods and events that we use to manipulate them. Generally, web elements are styled in a particular way by default, and also allow us to customize their styling with CSS.

Polymer allows you to build fully custom web elements of your own for more complex components composed of the building blocks you are used to with the standard set of HTML elements.

This course is an introduction to Polymer, and should get you started building your own customizable web elements that you can use on their own, or even with your favorite framework like Angular or React!

The Polymer library provides a set of features for creating custom elements. These features are designed to make it easier and faster to make custom elements that work like standard DOM elements.

Creating Custom Web Elements with Polymer 2

AngularJS is an open-source JavaScript framework, maintained by Google, that assists with running single-page applications. Its goal is to augment web-based applications with model–view–controller (MVC) capability, in an effort to make both development and testing easier.

TimelineLite is a piece of the Greensock TweenMax library that provides the ability to create sequenced animation with very little code or setup.

In this lesson we'll look at creating event listeners in our custom element using the listeners object as well as annotated event listeners.

Create Event Listeners in Polymer Elements

Custom element property changes can be observed by specifying an observer method which will be executed whenever a change occurs and receive both the new value and old value.

In this lesson we'll look at the lifecycle callbacks (Created, Ready, Attached, Detached, and attributeChanged) available to us in Polymer and how to use each one.

Use Lifecycle Callbacks On Custom Polymer Elements

Polymer provides us a variety of data-binding configurations.  In this lesson we'll look at configuring Two-way, One-way-down and One-way-up data binding.

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

React's use of the VirtualDOM can make it confusing on how to get actual elements to use in animation libraries like TweenMax. This video shows how to use this.getDOMNode() and this.refs and hook them in to TweenMax to satisfy all of your advanced animation needs.

Using TweenMax with React

We can utilize the "fire" method from within our custom element to execute a custom event.  In this lesson we'll create a custom event and pass useful data along with the event to the consumer of our element.

Execute Custom Events in Polymer

In this lesson we'll use the "dom-repeat" helper method in our custom element to iterate over a collection and use the built in model instantiation to update items in our collection.

Iterate over a Collection with Polymer's dom-repeate

In this lesson we'll install Polymer using bower and explore creating our first custom element. We will use the dom-module to create our first Element and add an event listener to watch for the `keyup` event.

Create a Custom Element using Polymer

In this lesson we'll look at how to isolate the style of our custom element, use the ":host" selector, and create css variables in order to theme our element.

Style Custom Elements in Polymer

Polymer allows us to extend a native HTML element's UI or functionality.  In this lesson we'll use a button as our custom element basis and add new UI and functionality to it that can be added to any button in our application.

Extend Native HTML Elements with Polymer

AngularJS animations and TweenLite make it really easy to create cool 3d effects in your application.

We can declare properties on our custom element which serve as a public api configurable by any user from markup.
