Rakkas projects can be built to run on Lagon, an upcoming JavaScript runtime for the edge. First, you should install the suitable HatTip adapter:

npm install -S @hattip/adapter-lagon

Then you should set the adapter option of Rakkas Vite plugin to "lagon":

import { defineConfig } from "vite";
import rakkas from "rakkasjs/vite-plugin";

export default defineConfig({
  plugins: [
      adapter: "lagon",

After building with rakkas build, you can run your project with lagon dev dist/server/entry-lagon.js --public-dir dist/client.


Lagon is in early development, so it is not ready for production use yet.
