quorum.js: JavaScript API for Quorum

quorum.js is an extension for web3.js which adds support for APIs specific to Quorum.

Features

• Provide js applications with easy access to all Quorum-specific APIs (including private transaction, consensus, and permissioning APIs)
• Works with web3.js smart contract wrappers

Requirements

• Node.js
• Running Quorum & Privacy Manager nodes

Installation

npm install quorum-js

Quickstart

The Quorum-specific API methods provided by quorum.js are accessed in one of two ways:

Extending web3 object

const Web3 = require("web3");
const quorumjs = require("quorum-js");

const web3 = new Web3("http://localhost:22000");

quorumjs.extend(web3);

web3.quorum.eth.sendRawPrivateTransaction(signedTx, args);

This makes Quorum-specific API methods available through the web3.quorum object.

RawTransactionManager object

Additional private transaction-specific APIs require access to a Privacy Manager:

const Web3 = require("web3");
const quorumjs = require("quorum-js");

const web3 = new Web3("http://localhost:22000");

const enclaveOptions = {
  privateUrl: "http://localhost:9081" // Tessera ThirdParty server url, use ipcPath if using Constellation
};

const txnMngr = quorumjs.RawTransactionManager(web3, enclaveOptions);

txnMngr.sendRawTransaction(args);

Examples

The 7nodes-test directory contains examples of quorum.js usage. These scripts can be tested with a running 7nodes test network.
