Simple example of storing data in your local ipfs node using ipld. Note that this only works when your local ipfs node is not running.

ipld-test.js

import dagCBOR from 'ipld-dag-cbor';
import IPLDResolver from 'ipld-resolver';
import BlockService from 'ipfs-block-service';
import IPFSRepo from 'ipfs-repo';

const repo = new IPFSRepo(process.env.HOME + '/.ipfs');
const ipfsBlockService = new BlockService(repo);
const resolver = new IPLDResolver(ipfsBlockService);

const node1 = {
  some: 'data',
  that: {
    is: 'structured',
  },
};

repo.open(() => {
  dagCBOR.util.cid(node1, (err, cid1) => {
    console.log('cid for', node1, 'is', cid1.toBaseEncodedString());
    resolver.put(node1, { cid: cid1 }, (err, cid) => {
      console.log('put', cid1.toBaseEncodedString(), 'in ipld');
      console.log('got error', err);
      console.log('got cid', cid.toBaseEncodedString());

      resolver.get(cid1, value => {
        console.log('got value back...', value);
        repo.close(() => {
          console.log('all done!');
        });
      });
    });
  });
});
