Prototype adapter to connect Sveltekit and Axum allowing a Rust based Axum HTTP server to serve a Sveltekit app (With SSR)
This allows your to add a layer to your Axum HTTP server that can serve a SvelteKit app with SSR, server routes, client rendering and prerendering support.
Using the Rust based Deno runtime and its node compatibility the Rust based Axum layer can invoke the SvelteKit request handling logic for SSR and server routes.
This library allows you to build your main app HTTP server in Rust while serving a svelte app from it yet still retaining the SvelteKit features like SSR and server routes.
Caution
Due to depending on the deno_runtime package you will see a substantially larger build time (Initial, incremental builds will take most of the time away) when including this package. You will also see a substantial increase in your binary size up to around 100Mb optimizing the binary for size you can get it down to around 60Mb
