Installation

Install the Svelte Query client:

1

Configuration

Svelte Query client provide a set of utilities to connect your APIs with svelte. Before we can use these functions, you need to modify your code generation to include the base typescript client.

Run wunderctl generate to generate the code.

In SvelteKit, you'll have to keep the generated files under the src/ directory

Now you can configure the svelte query functions. Create a new file, for example src/lib/wundergraph.ts and add the following code:

queryKey

You can use the queryKey helper function to create a unique key for the query in a typesafe way. This is useful if you want to invalidate the query after mutating.

If you are working with SvelteKit, this package provides prefetchQuery utility to help with SSR

This implementation is based on TanStack Svelte Query's prefetchQuery approach

Options

You can use all available options from Svelte Query with the generated functions. Due to the fact that we use the operationName + variables as key, you can't use the key option as usual. In order to use conditional-fetching you can use the enabled option.

You can configure the utilities globally by using the Svelte Query's QueryClient config.
