Using with preprocessors
Language specific setup
Generic setup
If a svelte file contains some language other than html, css or javascript, svelte-vscode needs to know how to 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).
// svelte.config.js
const preprocess = require('my-example-svelte-preprocessor');
module.exports = {
preprocess: [preprocess()],
// ...other svelte options
};
It's also necessary to add a type="text/language-name" or lang="language-name" to your style and script tags, which defines how that code should be interpreted by the extension.
<div>
<h1>Hello, world!</h1>
</div>
<style type="text/scss">
div {
h1 {
color: red;
}
}
</style>
Settings
svelte.language-server.runtime
Path to the node executable you would like to use to run the language server.
This is useful when you depend on native modules such as node-sass as without
this they will run in the context of vscode, meaning v8 version mismatch is likely.
