Using the ipfs-http-client I can successfully add data using the below method. The console.log(added) returns an object with the path, cid, and size keys.
However, the console.log(exists) line returns Object [AsyncGenerator] {}.
I would like to be able to check if a data string exists. Is this possible?
import { create as ipfsHttpClient } from 'ipfs-http-client'
const ipfsClient = ipfsHttpClient('https://ipfs.infura.io:5001/api/v0')
const handleData = async (data) => {
const added = await ipfsClient.add(data)
console.log(added)
const exists = await ipfsClient.get(data)
console.log(exists)
}
handleData('hello world')
The get method returns AsyncIterable<Uint8Array> object, which may be what you're printing out. To get each bytes, you will have to loop over it:
const cid = 'QmQ2r6iMNpky5f1m4cnm3Yqw8VSvjuKpTcK1X7dBR1LkJF'
for await (const buf of ipfs.get(cid)) {
// do something with buf
console.log(buf);
}
If all you care about is whether the data exists, you can just call next() method on the iterator and check for null or error.
const exists = (await ipfs.get(cid)).next() !== null
