const IotaClient = require('@decentralized-auth/iota');
const MamClient = require('@decentralized-auth/iota-mam');

// Instantiate a logger that has an info and error method
const consoleLogger = new (function () {
  this.info = console.log;
  this.error = console.log;
})();

const iota = new IotaClient({
  provider: 'http://node01.testnet.iotatoken.nl:16265',
  securityLevel: 2,
  depth: 5,
  minWeightMagnitude: 10,
}, consoleLogger);

const seed = await generateSeed();
const mode = 'restricted';
const sideKey = 'BANANA';
const mam = new MamClient(seed, iotaClient, mode, sideKey);

const message = 'HELLO';
const root = await mam.attach(message);

const res = await mam.fetch(root, 'restricted', sideKey);
