Live Example: https://sveltekit-template.vercel.app
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --openTo create a production version of your app:
npm run buildYou can preview the production build with npm run preview.
Once deployed on Vercel, you can benefit from Speed Insights simply by navigating to Vercel's dashboard, clicking on the 'Speed Insights' tab, and enabling the product.
You will get data once your application will be re-deployed and will receive visitors.
