Svelte

SvelteKit is a meta-framework for Svelte. Learn more about SvelteKit at https://kit.svelte.dev/. This guide is accurate as of SvelteKit 2.5.7 / Svelte 4.2.15.

Checklist

• Use SGG and/or SPA via static-adapter. Tauri doesn’t support server-based solutions.
• 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

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"
  }
}

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(),
  },
};

export default config;

4. Disable SSR:

Lastly, we need to disable SSR and enable prerendering 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 prerender = true;
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 Single-Page Application (SPA) mode over SSG, you can change the adapter configurations and +layout.ts according to the adapter docs.
