Hi @vijayee, we're currently in the middle of the next release of IPFS and the dependencies are a little wonky atm. Thanks for reporting the issue!

You will be able to get the ipfs-api example working by using a fork of js-ipf-api by installing it with npm npm i @haad/ipfs.api and then requiring it const IpfsApi = require('@haad/ipfs-api'). That version contains support for the missing pubsub both in js-ipfs-api and in the actual go-ipfs daemon.

We're working on getting the js-ipfs version working again, I 'm fairly confident that will land next week.

@haadcode, thanks, I'll give it a shot with this version of the api.

I get another error with the '@haad/ipfs-api' module coming from stream-to-json-value

We just released a new version which includes fixes for the examples. See https://github.com/haadcode/orbit-db/tree/master/examples for all the examples.

You can now do:

npm install orbit-db ipfs-daemon

const IPFS = require('ipfs-daemon/src/ipfs-node-daemon')
const OrbitDB = require('orbit-db')

const ipfs = new IPFS()

ipfs.on('error', (e) => console.error(e))
ipfs.on('ready', (e) => {
  const orbitdb = new OrbitDB(ipfs)

  const db = orbitdb.eventlog("feed name")

  db.add("hello world")
    .then(() => {
      const latest = db.iterator({ limit: 5 }).collect()
      console.log(JSON.stringify(latest, null, 2))
    })  
})

@vijayee, thanks for waiting. If you encounter more problems, let us know!
