turtle.io

build status Gitter

turtle.io is very easy to get up and running! All you need to do is install it, and tell it what directory holds your web sites, & which hostnames to answer for.

You can also create complex web applications, with a familiar API.

Getting Started

  1. Install the module with: npm install turtle.io
  2. Create a script to load & start a server. You could use sample.js in the turtle.io directory (./node_modules/turtle.io) as a template, or see the examples below
  3. [Optional] You can override defaults by passing the factory an Object

The following examples assume you've installed turtle.io into /opt/turtleio, if this is not the case you need to edit the applicable file to correct the path.

Upstart

Use the provided upstart recipe: sudo sh -c 'cp node_modules/turtle.io/turtleio.conf /etc/init; initctl reload-configuration; service turtleio start;'

Systemd

Use the provided systemd service: sudo sh -c 'cp node_modules/turtle.io/turtleio.service /etc/systemd/system; systemctl enable turtleio; systemctl start turtleio;'

What about Windows?

It runs great on Windows, but you're on your own to daemonize it!

Examples

turtle.io requires a default virtual host to be specified, because it is the failover when a request can't be routed.

Virtual hosts

Virtual host keys are the hostname, and the value is the directory relative to "root".

const turtleio = require("turtle.io");
let server = turtleio({
    default: "mysite.com",
    port: 80,
    uid: 100,
    root: "/var/www",
    hosts: {
        "mysite.com": "mysite.com",
        "another-domain.com": "another-domain.com"
    }
});

server.start();

Benchmark with express.js

siege was used instead of ab because we want to compare accurate transaction rates.

Specs

  • Machine MacBook Air (Early '14) / Core i7 @ 1.7Ghz / 8GB ram / 512 flash / OS X 10.10.2
  • ulimit 2560
  • express 4.11.2
  • turtle.io 3.2.2
  • benchmark siege -c100 -b -q -H 'Connection: Keep-Alive' -t15S localhost:$@

Test

express.js

Hello World! from a route (content-length: 12), no allow header.

var express = require("express"),
    app = express();

app.get('/', function (req, res) {
  res.send('Hello World!')
})

app.listen(3000);
turtle.io

Hello World! html file streamed from disk (content-length: 53), has accurate allow header.

"use strict";

require("index.js")({
    default: "test",
    root: __dirname + "/sites",
    port: 8000,
    hosts: {
        "test" : "test"
    },
    logging: {
        enabled: false
    }
}).start();

Transactions/s

Transaction rates are similar.

  • turtle.io [1233.78, 1203.2, 1187.44] (1208.14 avg)
  • express [1105.85, 1124.25, 1167.57] (1132.56 avg)

Handling Uploads

The request object is passed to every route handler as the second argument, will have a body property with the payload from the Client. It will not be coerced to another format, so if you expect JSON, you'll have to JSON.parse() it yourself (for now).
