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.

Setup

1. Traverse to ~/.bitcoin or ~/Library/Application Support/Bitcoin and add a file called bitcoin.conf if it doesn't already exist.

2. Add these lines to the file:

   rpcuser=username

   rpcpassword=password

You will use these to login to the server.

3. Start your Bitcoin client with the -server argument or run bitcoind

4. You should now be able to communicate with Bitcoin JSON-RPC API using the node-bitcoin library, try it out!

Example

var bitcoin = require('bitcoin');
var client = new bitcoin.Client('localhost', 8332, 'username', 'password');

client.getBalance(function(balance) {
  console.log("Balance:", balance);
}
