web-component-demo

Demonstration of vanilla web components and their unit tests. This is a proof-of-concept showing how vanilla JavaScript can support a single-page application (SPA).

Running the app

1. npm install to get dependencies
2. npm run makeTestCertificates to set up the localhost HTTPS certificates
3. npm run start:localhost to start the server in localhost
4. Navigate to https://localhost:3000 in your browser and allow the test certificates
5. Visit the "Slideshow" page to learn more about the app

Why vanilla web components?

• Self-contained and reusable
• Usable in any framework or none
• Synchronous events and lifecycles
• Supported in all modern browsers
  • ... although you'll need a polyfill for customized built-in components in Safari
