Communicate with bitcoind via JSON-RPC

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.

npm install bitcoin

// all config options are optional 
var client = new bitcoin.Client({
  host: 'localhost',
  port: 8332,
  user: 'username',
  pass: 'password',
  timeout: 30000
});
client.getBalance('*', 6, function(errbalanceresHeaders) {
  if (err) return console.log(err);
  console.log('Balance:', balance);
});
client.cmd('getbalance', '*', 6, function(errbalanceresHeaders){
  if (err) return console.log(err);
  console.log('Balance:', balance);
});
var batch = [];
for (var i = 0; i < 10; ++i) {
  batch.push({
    method: 'getnewaddress',
    params: ['myaccount']
  });
}
client.cmd(batch, function(erraddressresHeaders) {
  if (err) return console.log(err);
  console.log('Address:', address);
});

See Enabling SSL on original client.

If you're using this to connect to bitcoind across a network it is highly recommended to enable ssl, otherwise an attacker may intercept your RPC credentials resulting in theft of your bitcoins.

When enabling ssl by setting the configuration option to true, the sslStrict option (verifies the server certificate) will also be enabled by default. It is highly recommended to specify the sslCa as well, even if your bitcoind has a certificate signed by an actual CA, to ensure you are connecting to your own bitcoind.

var client = new bitcoin.Client({
  host: 'localhost',
  port: 8332,
  user: 'username',
  pass: 'password',
  ssl: true,
  sslStrict: true,
  sslCa: fs.readFileSync(__dirname + '/myca.cert')
});
