Sails

Sails makes it easy to build custom, enterprise-grade Node.js apps. It is designed to resemble the MVC architecture from frameworks like Ruby on Rails, but with support for the more modern, data-oriented style of web app development. It's especially good for building realtime features like chat.

Philosophy

Like other MVC frameworks, Sails espouses a same convention-over-configuration philosophy and emphasis on developer happiness, but takes it a step further. Like Node.js, using Sails means your app is written entirely in JavaScript, the language you or your team is already using to build the frontend portion of your web or mobile web app. This cuts development to a fraction of the time. We've used Sails to build production-ready, realtime apps in a matter of weeks. In the past, that would have taken us months!

Performance

Meanwhile, since Sails is written in Node.js, your servers reap the performance benefits of an event-driven, asynchronous architecture. (http://venturebeat.com/2011/08/16/linkedin-node/)

Standing on the shoulders of giants

Sails is built on the rock-solid foundation of Express (routing), EJS (templating) and Socket.io (cross-platform WebSockets), you don't have to worry about reinventing the wheel.

What else?

Sails does a few things other Node.js MVC frameworks can't do:

• Automatically generated JSON API for manipulating models means you don't have to write any backend code to build simple database apps
• Built-in authentication, role-based access control, and customizable policies assignable at the controller/action level
• Transport agnostic routing: Sails controllers also handle Socket.io / WebSocket messages! This makes it much easier to send the server-originated or 'comet' notifications you need for features like chat, realtime analytics, and multiplayer games.
• Automatic asset minification with Rigging: Your UI code is automatically included in development mode, and minified into a simple, gzipped file in production.
  • Support for:
    • CoffeeScript
    • LESS
    • SASS / SCSS

Installation

npm install sails

Or to install with the command line tool: sudo npm install -g sails

Getting Started

If you installed Sails with the command line tool above, the following command will generate a new Sails project, nameOfNewApp/, in the current directory:

sails nameOfNewApp

Then run the app:

cd nameOfNewApp
node app.js

Dependencies and Compatibility

Tested with node 0.8.1 Sails is built on the rock-solid foundations of ExpressJS and Socket.io.

Who Built This?

The Sails framework was developed by Mike McNeil (@mikermcneil) and is maintained by Balderdash (@balderdashy), a realtime web & mobile studio I started with Heather White (@hdesignsit) in Austin, TX.

After building a few realtime javascript apps and taking them into production, we realized that the JavaScript development landscape is very much still the Wild West. Over time, after trying lots of different methodologies (on the front end and the back), we decided to crystallize all of our best practices into this framework. I hope it saves you some time :)

License

Sails is built around so many great open-source technologies that it would never have crossed our minds to keep it proprietary. We owe huge gratitude and props to TJ Holowaychuk (@visionmedia) and Guillermo Rauch (@guille) for the work they did, as well as the stewards of all the other open-source modules we use. Sails could never have been developed without your tremendous contributions to the node community.
