node-bitcoin

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.

Install

npm install bitcoin

Examples

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);
});

Batch multiple RPC calls into single HTTP request

var batch = [];
for (var i = 0; i < 10; ++i) {
  batch.push({
    method: 'getnewaddress',
    params: ['myaccount']
  });
}
client.cmd(batch, function(err, address) {
  if (err) return console.log(err);
  console.log('Address:', address);
});
