If a svelte file contains some language other than `html`, `css` or `javascript`, `svelte-vscode` needs to know how to [preprocess](https://svelte.dev/docs#svelte_preprocess) it. This can be achieved by creating a `svelte.config.js` file at the root of your project which exports a svelte options object (similar to `svelte-loader` and `rollup-plugin-svelte`). It's recommended to use the official [svelte-preprocess](https://github.com/sveltejs/svelte-preprocess) package which can handle many languages.

**Note**: `svelte-preprocess` supports passing an array of preprocessors (e,g, `preprocess: [postcss(), typescript()]`), but this is **not** currently supported by the language server.

```js
// svelte.config.js - NOTE: you cannot use the new "import x from y" and "export const" syntax in here.
const sveltePreprocess = require('svelte-preprocess');
