About the Polymer Project

As a team of front-end engineers embedded in the Chrome team, our mission is to make the web better, by helping developers unlock the web’s full potential and by spurring the web platform to evolve and improve.

We work on libraries, tools and patterns to help developers build modern Progressive Web Apps, taking advantage of cutting-edge features like Web Components, Service Workers and HTTP/2.

We also participate in the standards process, doing our part to ensure that front-end developers have a strong voice in the evolution of the platform.

More About the Project

Why Web Components?

Web Components are the web platform's native solution for component-based development.

With Web Components, you can create reusable custom elements that interoperate seamlessly with the browser’s built-in elements, or break your app up into right-sized pieces, making your code cleaner and less expensive to maintain.

Our products sprinkle a bit of sugar over the standard Web Components APIs and shine a light on best practices for building elements and apps, making it easier for you to get great results.
