libp2p package is not working with Bun

[ansarizafar]

What version of Bun is running?

0.7.1

What platform is your computer?

Linux 5.19.0-50-generic x86_64 x86_64

What steps can reproduce the bug?

I have installed libp2p, @libp2p/webtransport, @chainsafe/libp2p-noise packages with bun add command and I am trying to run following code with bun run index.js command

import { createLibp2p } from 'libp2p'
import { webTransport } from '@libp2p/webtransport'
import { noise } from '@chainsafe/libp2p-noise'

const node = await createLibp2p({
  transports: [webTransport()],
  connectionEncryption: [noise()],
 
})

// start libp2p
  await node.start()
  console.log('libp2p has started')

  // print out listening addresses
  console.log('listening on addresses:')
  node.getMultiaddrs().forEach((addr) => {
    console.log(addr.toString())
  })

  // stop libp2p
  await node.stop()
  console.log('libp2p has stopped')

What is the expected behavior?

Code is working with Nodejs and it should run without error with Bun

What do you see instead?

Looks like this is because Bun is missing support for a Node.js feature: https://nodejs.org/api/util.html#custom-promisified-functions

Also in /node_modules/@libp2p/crypto/dist/src/keys/ed25519.js:5:16

const keypair = promisify(crypto.generateKeyPair);

Bun, doesn't support crypto.generateKeyPair yet, I'll look into that

Any update on this? Having a similar issue on Bun 1.0.1 with the following code.

import { createGrpcTransport } from '@bufbuild/connect-node'

createGrpcTransport({
  httpVersion: '2',
  baseUrl: 'http://127.0.0.1:8080',
})

I've never used libp2p, but a quick glance at the specs says it uses protobuf to describe the protocols used.

The protocols described below all use protocol buffers (aka protobuf) to define message schemas.

So possibly there's some gRPC in there which is built on top of HTTP2. According this this comment (in #4414), Bun does not support HTTP2 yet, which also explains why the code in my previous comment doesn't work as it uses @bufbuild/connect-node, a gRPC lib.
