echos

Echos is a simple echo server and client. More specifically, echos allows you to setup an echo server that will replay any text sent to it. Echos also comes with a client that allows you to send an echo request to a server, and it will print it back.

Installation

####Local

$ npm install echos

####Global

$ npm install -g echos

Usage – Command line

Server

Usage: ./echos server -p,--port <port> -q,--quiet
Usage: ./echos-server -p,--port <port> -q,--quiet

Options:
  -p, --port   [default: 1024]
  -q, --quiet  [default: false]

Client

Usage: ./echos client message -p,--port <port> -h,--host <host>
Usage: ./echos-client message -p,--port <port> -h,--host <host>

Options:
  -p, --port       [default: 1024]
  -h, --host       [default: "127.0.0.1"]
  -t, --timestamp  [default: false]

Example

Running the server on port 1337

$ ./bin/echos server -p 1337

Run the client to connect to the server on port 1337 and send Hello World!

$ ./bin/echos client Hello World! -p 1337 -t

When the server receives an echo request from the client it will log out something like this:

Echo message received:
    Hello World!
    From address: 127.0.0.1
    Time: Sat Jan 04 2014

After the client receives the echo response from the server it will log out something like this:

Hello World! time=7ms

Usage – As a module

Initialize

var echos = require('echos');

Create server

echos.server.start({port: 1337, quiet: false, callback: function(data){}});

Send echo from client

echos.client.echo('Hello World!', {port: 1337, timestamp: true, callback: function(data){}});
