@sveltejs/vite-plugin-svelte

usage

// vite.config.js
const svelte = require('@sveltejs/vite-plugin-svelte');
const { defineConfig } = require('vite');

module.exports = defineConfig(({ command, mode }) => {
	const isProduction = mode === 'production';
	return {
		plugins: [
			svelte({
				/* inline options here */
			})
		],
		build: {
			minify: isProduction
		}
	};
});

Options

vite-plugin-svelte reads the vite configuration and uses an appropriate default configuration

It also loads svelte.config.js (or svelte.config.cjs) from the configured vite.root directory automatically.

Options are applied in the following order:

vite-plugin-svelte defaults
svelte.config.js in vite.root
inline options passed in vite.config.js

It supports all options from rollup-plugin-svelte and some additional options to tailor the plugin to your needs.

For more Information check options.ts

Integrations for other vite plugins

Add an extra preprocessor

vite-plugin-svelte uses the svelte compiler to split .svelte files into js and css and the svelte compiler requires that the css passed to it is already plain css. If you are building a plugin for vite that transforms css and want it to work out of the box with vite-plugin-svelte, you can add a sveltePreprocess: PreprocessorGroup to your vite plugin definition and vite-plugin-svelte will pick it up and add it to the list of svelte preprocessors used at runtime.

const vitePluginCoolCss = {
	name: 'vite-plugin-coolcss',
	sveltePreprocess: {
		/* your PreprocessorGroup here */
	}
	/*... your cool css plugin implementation here .. */
};
