The Polymer App Toolbox is a collection of components, tools and templates for building Progressive Web Apps with Polymer.
Follow the instructions below to install, build, and deploy a project using an App Toolbox template in less than 15 minutes.
Install Polymer CLI
Polymer CLI is an all-in-one command line tool for Polymer projects. In this tutorial you use Polymer CLI to initialize, serve, and build your project. You can also use it for linting and testing, but this tutorial won't cover those topics.
Polymer CLI requires Node.js, npm, Git and Bower. For full installation instructions, see the Polymer CLI documentation.
To install Polymer CLI:
npm install -g polymer-cli
Initialize your project from a template
Create a new project folder to start from.
mkdir my-app cd my-app
Initialize your project with an app template.
Press the down arrow until
polymer-2-starter-kitis highlighted and press the enter / return key to select.
Serve your project
The App Toolbox templates do not require any build steps to get started developing. You can serve the application using the Polymer CLI, and file changes you make will be immediately visible by refreshing your browser.
To serve your project:
polymer serve --open
The diagram below is a brief summary of the files and directories within the project.
