**You don't need to do any of this to use Web Awesome!** This page is for people who want to contribute to the project, tinker with the source, or create a custom build of Web Awesome.
Components are built with [LitElement](https://lit-element.polymer-project.org/), a custom elements base class that provides an intuitive API and reactive data binding. The build is a custom script with bundling powered by [esbuild](https://esbuild.github.io/).
This will spin up the dev server. After the initial build, a browser will open automatically. There is currently no hot module reloading (HMR), as browser's don't provide a way to reregister custom elements, but most changes to the source will reload the browser automatically.
You can also run `npm run build:serve` to start an [`http-server`](https://www.npmjs.com/package/http-server) instance on `http://localhost:4000` after the build completes, so you can preview the production build.
This will generate a source file, a stylesheet, and a docs page for you. When you start the dev server, you'll find the new component in the "Components" section of the sidebar.
Web Awesome is an open source project and contributions are encouraged! If you're interesting in contributing, please review the [contribution guidelines](CONTRIBUTING.md) first.
