compilerOptions: {
dev: true
}
})
]
}

plugins: [
svelte({
})
],
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.
