    "ipfs-block-service": "^0.18.0",
    "ipfs-repo": "^6.0.3",
    "ipld": "^0.27.1",

Type: Bug

Severity: High

Description:

Readme usage instructions don't work... https://github.com/ipld/js-ipld#usage

Steps to reproduce the error:

(typescript, but just drop the any's...)

const path = require('path');
const Ipld = require('ipld');
const IpfsRepo = require('ipfs-repo');
const IpfsBlockService = require('ipfs-block-service');

jest.setTimeout(10 * 1000);
it('can put and get ipld', done => {
  const initIpld = (ipfsRepoPath: any, callback: any) => {
    const repo = new IpfsRepo(ipfsRepoPath);
    repo.init({}, (err: any) => {
      if (err) {
        return callback(err);
      }
      repo.open((err: any) => {
        if (err) {
          return callback(err);
        }
        const blockService = new IpfsBlockService(repo);
        const ipld = new Ipld({ blockService: blockService });
        return callback(null, ipld);
      });
    });
  };

  initIpld(path.join(__dirname, './ipld-golem'), (err: any, ipld: any) => {
    // Do something with the `ipld`, e.g. `ipld.get(…)`
    console.log(err, ipld);
    done();
  });
});

test hangs for 10 seconds, done is never called... can't use ipld.

was this working before for you and only just stopped working, or are you trying this from scratch without it previously working?

Thanks for your bug report. The problem is that ipfs-repo is using async/await instead of callbacks. The updated code can be found here https://github.com/ipld/js-ipld/pull/290/files#diff-04c6e90faac2675aa89e2176d2eec7d8.
