Install

This project uses npm and node

npm install orbit-db ipfs

Usage

First, create an instance of OrbitDB:

const IPFS = require('ipfs')
const OrbitDB = require('orbit-db')

const ipfs = new IPFS()
const orbitdb = new OrbitDB(ipfs)

Get a feed database and add an entry to it:

const feed = orbitdb.feed('haad.posts')
feed.add({ title: 'Hello', content: 'World' })
  .then(() => {
    const posts = feed.iterator().collect()
    posts.forEach((post) => {
      let data = post.payload.value
      console.log(data.title + '\n', data.content)
      // Hello
      //  World   
    })
  })

Later, when the database contains data, load the history and query when ready:

const feed = orbitdb.feed('haad.posts')
feed.events.on('ready', () => {
  const posts = feed.iterator().collect()
  posts.forEach((post) => console.log(post.title + '\n', post.content))
  // Hello
  // World  
})
