SvelteKit

SvelteKit is a meta framework for Svelte. Learn more about SvelteKit at https://kit.svelte.dev/. This guide is accurate as of SvelteKit 2.20.4 / Svelte 5.25.8.

Checklist

• Use SSG and SPA via static-adapter. Tauri doesn’t support server-based solutions.
• If using SSG with prerendering, be aware that load functions will not have access to tauri APIs during the build process of your app. Using SPA mode (without prerendering) is recommended since the load functions will only run in the webview with access to tauri APIs.
• Use build/ as frontendDist in tauri.conf.json.

Example Configuration

1. Install @sveltejs/adapter-static

   npm

   npm install --save-dev @sveltejs/adapter-static

   yarn

   yarn add -D @sveltejs/adapter-static

   pnpm

   pnpm add -D @sveltejs/adapter-static

   deno

   deno add -D npm:@sveltejs/adapter-static

2. Update Tauri configuration

   npm

   tauri.conf.json

   {
     "build": {
       "beforeDevCommand": "npm run dev",
       "beforeBuildCommand": "npm run build",
       "devUrl": "http://localhost:5173",
       "frontendDist": "../build"
     }
   }

   yarn

   tauri.conf.json

   {
     "build": {
       "beforeDevCommand": "yarn dev",
       "beforeBuildCommand": "yarn build",
       "devUrl": "http://localhost:5173",
       "frontendDist": "../build"
     }
   }

   pnpm

   tauri.conf.json

   {
     "build": {
       "beforeDevCommand": "pnpm dev",
       "beforeBuildCommand": "pnpm build",
       "devUrl": "http://localhost:5173",
       "frontendDist": "../build"
     }
   }

   deno

   tauri.conf.json

   {
     "build": {
       "beforeDevCommand": "deno task dev",
       "beforeBuildCommand": "deno task build",
       "devUrl": "http://localhost:5173",
       "frontendDist": "../build"
     }
   }

3. Update SvelteKit configuration:

   svelte.config.js

   import adapter from '@sveltejs/adapter-static';
   import { vitePreprocess } from '@sveltejs/vite-plugin-svelte';
   
   /** @type {import('@sveltejs/kit').Config} */
   const config = {
     // Consult https://kit.svelte.dev/docs/integrations#preprocessors
     // for more information about preprocessors
     preprocess: vitePreprocess(),
   
     kit: {
       adapter: adapter({
         fallback: 'index.html',
       }),
     },
   };
   
   export default config;

4. Disable SSR

   Lastly, we need to disable SSR by adding a root +layout.ts file (or +layout.js if you are not using TypeScript) with these contents:

   src/routes/+layout.ts

   export const ssr = false;

   Note that static-adapter doesn’t require you to disable SSR for the whole app but it makes it possible to use APIs that depend on the global window object (like Tauri’s API) without Client-side checks.

   Furthermore, if you prefer Static Site Generation (SSG) over Single-Page Application (SPA) mode, you can change the adapter configurations and +layout.ts according to the adapter docs.
