PWABuilder is built with the following technology stack:

Specifically, we will be discussing the following technology stack:

  • lit-element: Our framework. Lit-element gives us a way to write code that feels remarkably familiar to popular frameworks like React but that compiles down to browser native Web Components with a tiny runtime that provides things such as performant asynchronous rendering.

  • Shadow DOM, CSS Variables, Shadow Parts: Modern CSS is incredibly powerful, especially when combining the Shadow DOM, CSS variables and the Shadow Parts APIs. We will discuss how this provides everything we normally were using a CSS pre-processor, but without the extra complication that a CSS pre-processor adds to your build steps!

  • Rollup: Rollup is a “bundler” or build tool that will make working with NPM modules easy while also helping ensure our code is ready for production. It allows us to do things such as minify our code, run Workbox (another tool I will introduce next) and other build steps.

  • Workbox: Workbox is a tool that makes working with Service Workers easy!

  • TypeScript: TypeScript gives us features such as auto complete in our editors that helps make the development process easier, along with being perfect for working in a team because you can provide types for your APIs, making your code almost self-documenting.

  • Project Fugu: Project Fugu is an initiative involving Microsoft, Google, Samsung and many others that aims to bring all the capabilities of native apps to the Web! The APIs that this project has already brought to browsers like Edge, such as the Wake Lock API, Web Bluetooth, the File System Access API and more act as our “native toolkit” in this tech stack. The cool thing though is that all of these APIs are built into the browser and work just like any other JavaScript API you may have used, such as the Geolocation API.
