Pages and layouts have access to a special method called load. npm create svelte@latest my-app cd my-app npm install npm run dev -- --open Back to the frontend. In our case, we want to create a src/routes/login.js file and map the GET http verb to the exported get function. You can find the complete code in src/db.ts.
