WS-Telegraph

This is a simple set of scripts that implement RPC over WebSocket. As communication layer
used engine.io library.

User Guide

The package provides two classes: WsTgServer and WsTgClient.

WsTgServer based on Engine.IO and processes requests. WsTgClient provides a way
to invoke methods on the server through websocket and obtains the result of the call.

Old js-style

``javascript
const WsTgClient = require('ws-telegraph').WsTgClient;
const WsTgServer = require('ws-telegraph').WsTgServer;

class Server extend WsTgServer {
onHello(userName){
return new Promise((resolve)=>{
return resolve(Hello, ${userName});
});
}
}

class Client extent WsTgClient {
callHello(userName){
return this.callAndWait('hello', 'Bob'); // Promise with result "Hello, Bob"
}
}
`

With Babel

`javascript
import {WsTgClient, WsTgServer} from 'ws-telegraph';

class Server extend WsTgServer {
async onHello(userName){
return Hello, ${userName};
}
}

class Client extent WsTgClient {
async callHello(userName){
return await this.callAndWait('hello', 'Bob');
}
}
`
