How to create an IPFS compatible multihash

Question

I\'m trying to create an IPFS compatible mutihash but it is not matching. I am asking here because I have not yet found an example that takes this from hashing to the end r

Answer 1

Some of the other answers are outdated. This is what worked for me:

    const Unixfs = require('ipfs-unixfs'); // @0.1.16
    const { DAGNode } = require('ipld-dag-pb'); // @0.18.1
    const bs58 = require('bs58'); // @4.0.1

    // ...

    const data = Buffer.from('hello world');
    const unixFs = new Unixfs('file', data)
    const dagNode = new DAGNode(unixFs.marshal());
    const link = await dagNode.toDAGLink();
    const multihash = bs58.encode(link._cid.multihash).toString();
    console.log(multihash); // Qmf412jQZiuVUtdgnB36FXFX7xg5V6KEbSJ4dpQuhkLyfD
