Note

This documentation is for a work currently in progress and medjs 1.0 is not yet released.

Tutorial

This section handles several examples to use medjs.

var Medjs = require('medjs');
var medjs = Medjs.init(['http://localhost:9921']);
var Account = medjs.local.Account;
var Client = medjs.client;
var HealthData = medjs.healthData;
var Transaction = medjs.local.transaction;

---

send data upload transaction

// create a new account
var account = new Account();
// get account state
Client.getAccountState(account.pubKey, 'tail').then((res) => {
  var nonce = parseInt(res.nonce, 10);

  // calculate hash of the medical data file
  HealthData.hashDataFromFile('/file/path', 'medical-fhir', 'observation').then((hash) => {
    // creating a medical data payload
    var healthDataPayload = Transaction.createDataPayload(hash);

    // creating a medical data upload transaction
    var tx = Transaction.dataUploadTx({
      from: account.pubKey,
      payload: healthDataPayload,
      nonce: nonce + 1
    });

    // sign transaction
    account.signTx(tx);

    // send transaction
    Client.sendTransaction(tx).then((res2) => {
      // .. do something
    });
  });
});
