Windows support is on Bun's roadmap (until then, it is only available on *nix systems)

Windows support

• The HTTP client needs a Windows implementation for the syscalls
• Bun needs test coverage for Windows filepath handling
• All of bun's dependencies need to compile on Windows
• Building JavaScriptCore needs to work on Windows and the JIT tiers need to work. I don't know what the current status of this is. WebKit's bug tracker suggests it may not have JITs enabled which will likely need some patches to fix it.

I guess Bun does not YET implement all node.js api's. I tried http and it seems currently missing. And as much I understand it currently has its own built-in HTTP server.

Check the "Getting started" section on -> https://bun.sh/

A sample server:

    export default {
      port: 3000,
      fetch(request) {
        return new Response("Welcome to Bun!");
      },
    };

(This example reminds me of serverless functions.) As this is the case, it seems you can not rely on Node.js http, or most probably any server framework like express.

At least for now, bun's roadmap (https://github.com/oven-sh/bun/issues/159) shows a line, which I am not sure is talking about node's http server or sth. else about Bun's own server.

Once complete, the next step is integration with the HTTP server and other Bun APIs
