node-gridcoin

node-gridcoin is a simple wrapper for the Gridcoin client's JSON-RPC API.

Install

npm install node-gridcoin

Examples

Create client

var client = new gridcoin.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 gridcoinresearchd across a network, it is highly recommended to enable ssl otherwise an attacker may intercept your RPC credentials resulting in theft of your Gridcoins.

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

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

If you're 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 default node won't work with untrusted certificates.
