# bitcoin-lib

Talk to a bitcoin-core node. 
This library implements all the jsonrpc calls using the [request](https://www.npmjs.com/package/request) library and

## Installation 

----
	npm install bitcoin-lib
----

### Usage example

----
	const BitcoinLib = require("bitcoin-lib");
	var bitlib = new BitcoinLib();

	bitlib.start()
    .then(function(){
        return bitlib.getrawtransaction([transactionid, true]);
    })
    .then(function(res){
    	var tx = tes.result;
    	console.log(tx);
	})
	.then(function(){
    	return bitlib.getbalance('wallet name', ["*", 6]);
	})
    .catch(function(err){
    	console.error(err);//Something went wrong during initialization/authentication to the bitcoin-core node	
	})

### Calls for wallets

Unfortunatelly, the RPC endpoint for wallets is different. In my opinion, this should be changed in
bitcoin-core. Instead of a path, it should be a query parameter or just an additional parameter. 
The RPC endpoint for wallets is 'http://127.0.0.1:8332/wallet/<walletname>'. In the example above, the 
wallet name is the first parameter and the parameters for the call are in the array.
