Each source folder builds independently.

pnpm build          # all source folders
pnpm build front    # specific folder

Running in Production

The simplest deployment - just run the bundled server directly:

node dist/front/api/server.js

For more control, use the app factory at dist/*/api/app.js.

Koa - app.callback() is a Node.js (IncomingMessage, ServerResponse) handler. Deno and Bun support it via their node:http compat layer, not via their native serve APIs:

Node / Deno / Bun

import { createServer } from "node:http";

import app from "./dist/front/api/app.js";

createServer(app.callback()).listen(3000);

Hono - app.fetch is a Web Fetch API handler, so it plugs into each runtime's native server directly:

Node

import { createServer } from "node:http";
import { getRequestListener } from "@hono/node-server";

import app from "./dist/front/api/app.js";

createServer(getRequestListener(app.fetch)).listen(3000);

Deno

import app from "./dist/front/api/app.js";

Deno.serve({ port: 3000 }, app.fetch);

Bun

import app from "./dist/front/api/app.js";

Bun.serve({ port: 3000, fetch: app.fetch });
