svelte-loader

A webpack loader for Svelte components, allowing you to use Svelte with webpack. This version (3.2.4) supports Svelte 3, 4, and 5 (including runes mode). It handles Svelte files (.svelte) and with extra config supports TypeScript in Svelte files. Key differentiator: it's the official webpack integration from the Svelte team, maintained alongside SvelteKit and Vite plugin. Requires manual webpack configuration for CSS extraction, aliasing, and resolving conditions. Alternatives include vite-plugin-svelte for Vite users.
