TypeError: IPFS is not a constructor

Question

我正在尝试使用 Orbit-DB，所以我按照 the guide. But at the Create a database step，我得到一个错误：

const ipfs = new IPFS()
             ^

TypeError: IPFS is not a constructor

这是我的完整代码：

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

// Create IPFS instance
const ipfs = new IPFS()
ipfs.on('ready', async () => {
  const orbitdb = await OrbitDB.createInstance(ipfs)
  const db = await orbitdb.docs('opews-db-test1')
  const address = db.address
})

我检查了 require() 和 console.log() 没有错误，但似乎没有。所以我不知道如何解决...

Answer 1

IPFS 改变了你构建 IPFS 节点的方式，你可以试试这个代码：

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

async function main() {
  const ipfs = await IPFS.create();
  const orbitdb = await OrbitDB.createInstance(ipfs);
  const db = await orbitdb.docs('opews-db-test1');
  const address = db.address;
}

main();

一个完整的例子：

<!doctype html>
<html>
<head>
  <title>IPFS in the Browser</title>
  <script src="https://cdn.jsdelivr.net/npm/ipfs/dist/index.min.js"></script>
  <script src="https://cdn.jsdelivr.net/npm/orbit-db/dist/orbitdb.js"></script>
  <script type="text/javascript">
(async function main()
{
  node = await Ipfs.create({
  repo: "ipfs/shared",
  config: {"Bootstrap": ["/ipv4/127.0.0.1/tcp/4002/ws/ipfs/<your go-ipfs peer id>"]},
  EXPERIMENTAL: {pubsub: true }});

    console.log('Online status: ', node.isOnline() ? 'online' : 'offline')
    document.getElementById("status").innerHTML= 'Node status: ' + (node.isOnline() ? 'online' : 'offline')
    
    orbit = await OrbitDB.createInstance(node);


    docs = await orbit.docs('my-docs', { indexBy: 'name' })
    hash = await docs.put({name: 'shamb0t', followers: 500 })
    console.log(hash)
    console.log(docs.get('shamb0t')[0].followers)


    feed = await orbit.feed('my-feed');
    hash = await feed.add('hello');
    console.log(hash);
    console.log(feed.iterator({ limit: -1 }).collect()[0].payload.value)

//feed.del(hash)    
})()
  </script>
</head>
<body>
 
  <h1 id="status">Node status: offline</h1>

 
</body>
