Table of Contents
Install
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 log database and add an entry to it:
const log = orbitdb.eventlog('haad.posts')
log.add({ name: 'hello world' })
.then(() => {
const items = log.iterator().collect()
items.forEach((e) => console.log(e.name))
// "hello world"
})
Later, when the database contains data, load the history and query when ready:
const log = orbitdb.eventlog('haad.posts')
log.events.on('ready', () => {
const items = log.iterator().collect()
items.forEach((e) => console.log(e.name))
// "hello world"
})
See example/index.html for a detailed example. Note that to run this example, you need to have a local IPFS daemon running at port 5001.
