The Polymer library is in maintenance mode. For new development, we recommend Lit.

You're viewing an older version of the Polymer library documentation. Please see Polymer 3.0 for the latest.

You can publish your elements on WebComponents.org to make them available on the Internet; or you can host them privately.

The easiest way to make your reusable elements available is to publish your elements on WebComponents.org.

Before you publish on WebComponents.org, create a GitHub repository for your element. Make sure your repository has the following:

You should also document and test your elements before publishing. See Document your elements and Test your elements.

Once you've done this, you're ready to go. Return to the Publish page at WebComponents.org. Follow the instructions on the Publish page to add a badge and an inline demo to your element.

If you have elements that can't be made public, you can host them locally with indie-catalog.
