If 'warn', Svelte will treat errors as warnings and add them to the warning report. If 'throw', Svelte throws when a compilation error occurred. If false, no JavaScript or CSS is returned just metadata. If 'ssr', Svelte emits an object with a render method suitable for server-side rendering. If 'dom', Svelte emits a JavaScript class for mounting to the DOM. If 'cjs', creates a CommonJS module (with require and module.exports), which is useful in some server-side rendering situations or for testing. If 'esm', creates a JavaScript module (with import and export). It will normally be inferred from filename. String that sets the name of the resulting JavaScript class (though the compiler will rename it if it would otherwise conflict with other variables in scope). Your bundler plugin will set it automatically. String used for debugging hints and sourcemaps. The following options can be passed to the compiler. If you're having trouble, get help on Discord or StackOverflow. The Svelte team maintains a VS Code extension and there are integrations with various other editors and tools as well. With this, npm run build will generate HTML, JS and CSS files inside the dist directory. If you don't need a full-fledged app framework and instead want to build a simple frontend-only site/app, you can also use Svelte (without Kit) with Vite by running npm init vite and selecting the svelte option. css that you can insert into your HTML, but most others won't handle SSR. There are plugins for all the major web bundlers to handle Svelte compilation, which will output. SvelteKit utilizes Vite to build your code and handle server-side rendering (SSR). It also provides all the other pieces you need to build a web application such as a development server, routing, and deployment. SvelteKit will handle calling the Svelte compiler to convert your.
