esbuild-svelte

esbuild plugin that resolves and compiles .svelte files for bundling with esbuild. Current stable version 0.9.4, actively maintained. Supports Svelte 4 and 5 (peer dep range >=4.2.1 <6). Key differentiators: zero-config setup for CSS handling (external by default, can inject), built-in caching for incremental builds, and full support for Svelte preprocessors including TypeScript. Compared to alternatives like svelte-loader for webpack or vite-plugin-svelte, this plugin is tailored for esbuild's speed and simplicity, with minimal dependencies and straightforward API.
