By using Polymer, you can define a custom element once and reuse it throughout your project or in any future project, which can be particularly useful for building reusable UI components like navigation bars or buttons.

Here are some key characteristics of elements built with Polymer:

As a developer, you're likely no stranger to the idea of customizing your application to meet its unique needs. Custom Elements are a powerful tool in Polymer's arsenal, allowing you to build your own HTML elements from scratch.

You can register a new element by creating an ES6 class that extends Polymer.Element. This is a fundamental concept in building custom elements with Polymer. Building a new HTML element in Polymer is as easy as creating a new class and calling the customElements.define method, which registers the new element with the browser.

Polymer is built around the concept of web components, which allow you to create custom, reusable, and encapsulated HTML tags.

Custom elements are a key part of Polymer, enabling you to define your own HTML elements using JavaScript and giving them their own properties, methods, and events.

Polymer uses Shadow DOM to encapsulate the styles and structure of custom elements, preventing them from being affected by external styles and scripts.

HTML templates are used in Polymer to define the structure of custom elements, and can include placeholders for data binding and event handling.

Polymer's data binding system is powerful, allowing you to bind data to your custom elements and keep them up-to-date.

Polymer 3.0 is published on npm using JavaScript Modules, which means it can take advantage of the standard native JavaScript module loader available in all current major browsers.

You can install Polymer via npm and use the Polymer CLI to run your project in the browser. The polymer-cli's development server polymer serve automatically handles the transform to rewrite specifiers to URLs.

Here are some tools that can be used to serve and/or bundle Polymer elements:

Polymer 3.0 is now stable, marking a significant change in how Polymer is distributed from HTML Imports on Bower to JS modules on npm.

The API is almost entirely backward compatible with Polymer 2.0, with the only changes being the removal of APIs related to HTML Imports like importHref, and converting Polymer's API to be module-based rather than globals-based.

Migrating to Polymer 3.0 by hand is mostly mechanical, involving a few key steps: components should be defined in JS modules instead of in HTML, templates should be encoded in JS modules using a static get template() getter, and all dependencies should be imported JS module imports rather than HTML Imports.

Here are the specific changes you'll need to make:

The polymer-modulizer tool automates the vast majority of this migration work, making it much easier to convert your app or element to Polymer 3.0.
