svelte-smol

A SvelteKit adapter that compiles your whole app into a single standalone executable with bun build --compile. No node_modules, no JS files to ship. One binary plus its static assets.

Read the docs Source on GitHub npm

Use it

bun add -d @orochibraru/svelte-smol

// svelte.config.js
import adapter from "@orochibraru/svelte-smol";

export default {
  kit: { adapter: adapter() },
};

The compile step runs under the Bun runtime, so build with bun run vite build.

What you get

build/
├── server        # the compiled executable
├── client/       # static assets, served by the executable
└── prerendered/  # prerendered pages, served by the executable

Ship the whole build/ directory, or just server if a proxy or CDN serves the assets. The executable finds client/ and prerendered/ relative to its own path, so it runs from any working directory: ./build/server.

Details

Tiny images

A container with one binary in it. Nothing else to copy, nothing else to patch.

Docker healthcheck

A compiled healthcheck binary ships alongside the server, so HEALTHCHECK needs no curl in the image.

Native addon escape hatch

compile: false emits a plain bundle instead, for when sharp or better-sqlite3 refuse to be bundled.

Asset serving toggle

serveAssets hands static files to your proxy or CDN when you’d rather it didn’t do that job.

Cross-compilation

target builds for Linux, macOS, Windows or Alpine’s musl from any host — Bun fetches the matching runtime the first time you use it.
