[ShiromiTsukasa]

What version of Elysia is running?

1.4.13

What version of Node Adapter are you using?

1.4.1

What platform is your computer?

Linux 6.17.4-arch2-1 x86_64 unknown

What steps can reproduce the bug?

1. Copy the following program into a new project's index.ts

import node from "@elysiajs/node";
import { Elysia } from "elysia";

const app = new Elysia({
  adapter: node()
})
  .ws("/ws", {
    open(ws) { console.log(ws.data); }
  }).listen(3000, ({hostname, port}) => {
    console.log(`Elysia running at ${hostname}:${port}`);
  });

2. Run with npm run dev (this should be tsx watch src/index.ts for node project)
3. Open a websocket connection to the application (e.g. through Postman)
4. Observe

What is the expected behavior?

The bun version's output

pwsh> bun run dev
$ bun --watch src/index.ts
Elysia is running at localhost:3000

What do you see instead?

pwsh> npm run dev

> dev
> tsx watch src/index.ts

Elysia running at localhost:3000
