node-ethcoin

node-ethcoin is a simple wrapper for the geth client's JSON-RPC API. V 0.0.4

Install

npm install node-eth-rpc

Examples

Create client

var client = new ethcoin.Client({
  host: 'localhost',
  port: 8545,
  user: '',
  pass: ''
});

Create client for

var client = new ethcoin.Client({
  host: 'mainnet.infura.io',
  port: 443,
  path: '/v3/:projectId'
});

Get all accounts

client.cmd('personal_listAccounts', function(err, accounts){
  if (err) return console.log(err);
  console.log('personal_listAccounts:', accounts);
});

Getting the balance directly using cmd

client.cmd('eth_getBalance', 'accountAddress', 'latest', 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 darkcoind across a network it is highly recommended to enable ssl, otherwise an attacker may intercept your RPC credentials resulting in theft of your darkcoins.

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

var client = new darkcoin.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.
