===============


JSON-RPC 2.0 TCP implementation with persistent connections using promises - very fast and without dependencies
npm install json-rpc-client
var jsonrpc = require('json-rpc-client')
// create client and connect
var client = new jsonrpc({ port: 7070, host: '127.0.0.1'})
client.connect().then(function()
{
// send json rpc
client.send('add', [1,2]).then(function(reply)
{
// print complete reply
console.log(reply)
},
//transport errors
function(error)
{
console.error(error)
})
},
function(error)
{
console.error(error)
})
var jsonrpc = require('json-rpc-client')
// create client and connect
var client = new jsonrpc({ port: 7070, host: '127.0.0.1'})
try

yield client.connect()
// send json rpc
var reply = yield client.send('add', [1,2])
// print complete reply

var jsonrpc = require('./jsonrpc')
Creates a new RPC connection object.
Options:
* host: Host the client should connect to. Defaults to '127.0.0.1'.
* port: Port the client should connect to. Defaults to '7070'.
Sends json data through persisted tcp connection.
methodName: string
parameters: Object/Array with parameters
notification: true/false to make notification request (no reply)
* Promise - object containing reply data along with error
Closes RPC connection and returns promise afterwards.
Emitted when an error occurs.
Emitted once the RPC connection socket is fully closed. The argument
'had_error' is a boolean which says if there was an error.
