Bun

Bun is a fast, incrementally adoptable all-in-one JavaScript, TypeScript & JSX toolkit.

1. Check Bun’s Vite guide

2. Follow the Node adapter guide

3. Implement the serverEntrypoint using Bun APIs:

   src/server.ts

   import mod from "./handler";
   import * as http from "node:http";
   import sirv from "sirv";
   import { toFetchHandler } from "srvx/node"
   import { fileURLToPath } from "node:url";
   
   const server = Bun.serve({
       port: 3000,
       fetch(request) {
           const response = toFetchHandler(sirv(fileURLToPath(new URL("../client/", import.meta.url)), { dev: true }))(request);
           if (response.status !== 404) {
               return response;
           }
           return mod.fetch(request);
       },
   });
   
   console.log("Ready at http://localhost:3000");

4. After the build, run the server with bun ./dist/server/index.mjs
