Q1Domain Verified
In SvelteKit, what is the primary mechanism for defining API routes and handling server-side logic, particularly when leveraging TypeScript for type safety?
`src/routes/api/[slug].ts` files using standard Express.js middleware.
`src/app.ts` files where all server-side logic and API endpoints are declared.
`src/routes/+server.ts` files exporting HTTP method handlers (e.g., `GET`, `POST`) with typed request and response objects.
`src/lib/server/api.ts` files exporting functions that are automatically registered by SvelteKit.
Q2Domain Verified
When building a SvelteKit application with TypeScript and aiming for optimal performance, what is the recommended approach for fetching data that should be available on the initial page load, ensuring it's fetched server-side?
Implementing a custom `fetch` wrapper in `src/lib/utils/fetch.ts` that handles caching and SSR.
Using `onMount` in a Svelte component and performing a client-side `fetch` request.
Utilizing the `load` function in `+page.server.ts` or `+layout.server.ts` and returning the data as props.
Defining a global `fetch` interceptor in `src/hooks.server.ts` to modify incoming requests.
Q3Domain Verified
In a SvelteKit application using TypeScript, what is the most robust and type-safe way to define and validate form data submitted via a Svelte form action?
Manually parsing `event.request.formData()` and performing runtime checks within the form action.
Importing a pre-defined JSON schema and using `JSON.parse` to validate the incoming form data.
Relying on browser-native form validation attributes (`required`, `pattern`) exclusively.
Using a Zod schema defined in `src/lib/schemas.ts` and validating the form data within the `+page.server.ts` form action.
