node-bitcoin is a simple wrapper for the Bitcoin client's JSON-RPC API.

The API is equivalent to the API document here. The methods are exposed as lower camelcase methods on the bitcoin.Client object, or you may call the API directly using the cmd method.


npm install bitcoin


  1. Traverse to ~/.bitcoin or ~/Library/Application Support/Bitcoin and add a file called bitcoin.conf if it doesn't already exist.

  2. Add these lines to the file:



You will use these to login to the server.

  1. Start your Bitcoin client with the -server argument or run bitcoind

  2. You should now be able to communicate with Bitcoin JSON-RPC API using the node-bitcoin library, try it out!


Create client

var bitcoin = require('bitcoin');
var client = new bitcoin.Client('localhost', 8332, 'username', 'password');

Create client with single object

var client = new bitcoin.Client({
  host: 'localhost',
  port: 8332,
  user: 'username',
  pass: 'password'

Get balance across all accounts with minimum confirmations of 6

client.getBalance('*', 6, function(err, balance) {
  if (err) return console.log(err);
  console.log('Balance:', balance);

Getting the balance directly using cmd

client.cmd('getbalance', '*', 6, function(err, balance){
  if (err) return console.log(err);
  console.log('Balance:', balance);
