The Polymer CLI is a command line interface for building, managing and deploying Polymer applications.

Polymer CLI is a command-line interface for projects. It includes a build pipeline, a boilerplate generator for creating elements and apps, a linter, a development server, and a test runner.

Polymer CLI works with two types of projects:

  • Elements projects. In an element project, you expose a single element or group of related elements which you intend to use in other element or app projects, or distribute on a registry like Bower or NPM. Elements are reusable and organized to be used alongside other elements, so components are referenced outside the project.

  • Application projects. In an app project, you build an application, composed of Polymer elements, which you intend to deploy as a website. Applications are self-contained, organized with components inside the application.

For more information, see the project documentation or the GitHub project page.
