SparklePost

SparklePost is a demo application that implements interface patterns commonly found in native iOS and Android apps, using modern and performant web development techniques. It is written in SvelteKit, but the same techniques can be implemented in any JavaScript framework.

• Scroll & tab restoration when using back navigation (SvelteKit Snapshots)
• Installation & Offline support (PWA, Service Worker & online/offline event)

Developing

Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:

nvm use
npm run dev

# or start the server and open the app in a new browser tab
npm run dev -- --open

Building

To create a production version of your app:

npm run build

You can preview the production build with npm run preview.

To deploy your app, you may need to install an adapter for your target environment.
