node-coind

node-coind is a simple wrapper for crypto coin daemon client's JSON-RPC API.

Install

npm install node-coind

Examples

Create client

var client = new coind.Client({
  host: 'localhost',
  port: 15715,
  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);
});

SSL

See Enabling SSL on original client.

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

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 coind has a certificate signed by an actual CA, to ensure you are connecting to your own coind.

var client = new coind.Client({
  host: 'localhost',
  port: 15715,
  user: 'username',
  pass: 'password',
  ssl: true,
  sslStrict: true,
  sslCa: fs.readFileSync(__dirname + '/server.cert')
});

If your using a self signed certificate generated with something like

openssl x509 -req -days 365 -in server.cert -signkey server.key -out server.cert

then sslStrict should be set to false because by defult node wont work with untrusted certificates.
