Getting Started

  1. Install the npm package:
$ yarn add node-raiblocks-rpc
# or 
$ npm install node-raiblocks-rpc --save
  1. Require the RPC client into your project:
const RaiClient = require('node-raiblocks-rpc');
const NODE_ADDRESS = 'http://[urltonode|iptonode]:port';
 * decodeJSON is an optional boolean argument.
 * When set to true (default), the JSON string response is
 * parsed into a JSON object. Otherwise the string is returned.
const client = new RaiClient(NODE_ADDRESS [, decodeJSON]);
  1. Use methods attached to client to send RPC calls:


Head to the examples.js file for even more!

const client = new RaiClient(NODE_ADDRESS [, decodeJSON]);
// Some methods do not require arguments:
  .then(count => {
     * {
     *   "count": "1826834",
     *   "unchecked": "3385205"
     * }
  .catch(e => {
    // Deal with your errors here.
// Some methods require arguments:
  .then(balance => {
     * {
     *   "balance": "325586539664609129644855132177",
     *   "pending": "2309370929000000000000000000000000"
     * }
  .catch(e => {
    // Deal with your errors here.

Promise-wrapped responses

All method calls return native NodeJS promises. You need to use the then() / catch() pattern shown above. If the call was succesful, the data will be passed to then(), otherwise the error will be passed to catch().

Methods Names

The method calls are the same as the original RPC actions defined on the RaiBlocks wiki. (See

Example1: on the RaiBlocks wiki account_balance is called with account. For the NodeJS client, the method is account_balance and the argument is the account string.


The arguments to use for those methods are detailed in the inline documentation of the index.js. There are the same as those mentioned in the Monero documentation:

Returned value

If you havent specified any decodeJSON argument when you instantiated RaiClient, by default the returned data will already be parsed into a JSON object for you. Otherwise you will receive the original JSON string returned by the RaiBlocks network.


Testing is done with mocha, chai and chai-as-promised to test promises.

To run the tests:

$ yarn test
# or 
$ npm run test

The tests are located in the lib/tests.js file. They perform actual API calls to the RaiBlocks network through a local node. In order to prevent the tests from failing because of a timeout, tests are run with a timeout option of 100s. Tests can still fail if the local node is too slow.

If you want to just run one set of test (i.e a describe block), for let's say the account_balance() function, you can do so with this command:

$ ./node_modules/mocha/bin/mocha --grep [functionNameHere] --timeout 10000

For example, if you want to test account_balance:

$ ./node_modules/mocha/bin/mocha --grep account_balance --timeout 10000

You can be even more specific by adding only to the individual tests. Example for account_balance():

describe("RaiClient.account_balance()", done => {
+ it.only("should retrieve account balance", () => {
- it("should retrieve account balanve", () => {

Possible future features

  • Caching of some responses
    • First with javascript objects
    • Then with some external db, like Redis or SQLLite
  • Make the library Isomorphic, i.e work in web-browsers as well
  • Make the method calls also support callbacks
  • Setup automated testing with travis. Will need first to build a mock object for RaiBlocks to have deterministic tests


I currently work on this project during my free-time, but also during my work-time. As I'm my own boss, I take work time to work on personnal projects that I really believes in. But during this time, I don't win any money. I'm not doing that for money.

Anyway, if you consider support me, you can pay me a pack of Monster's cans for moore productive coding, :D.

I accept donations in form of RaiBlocks, Monero, Bitcoin, Etherum & IntenseCoin. You can also Patreon me !
