Do you like

web components?

Have you ever used them before?

Why not?

I just need something quick and easy.

I don't have time to learn another technology.

My app already exists, I don't want to have to rebuild it.

We already use
[insert MVC].

What is a web component?

"Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements."

tl;dr

Custom HTML elements

    <source src="devstories.mp4" type='video/mp4' />
    <source src="devstories.webm" type='video/webm' />
</video>

I thought this talk was about Polymer?

Web component framework

Web component easierifier

How do we use it?

Shake & bake

$ yo polymer

Polymer Starter Kit

  • Material design

  • Unit testing

  • Offline Caching

  • Build Tools

  • Custom Theming

Polymer Element Catalogue

Treat it like bootstrap

There's an element for that.

(Pretty much everyone at Google I/O)

Be lazy

Lazy is good

Using Polymer, today

By Sam Beckham

Using Polymer, today

Polymer has been brewing in the Google labs for a the last few years. It's an awesome framework, but it's not been stable enough to use in production; until now. With the release of Polymer v1.0, we can finally start using it in the real world. It's time to take another look. In this talk I'll run through a quick overview of what Polymer is and what it does. I'll go over the re-vamped Polymer elements that get you up and running with a slick looking web app really quickly and I'll also dive in to how you can go about creating your own components.
