Sails.js is a web framework that 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 & API development. It's especially good for building realtime features like chat.
Since version 1.0, Sails supports
awaitout of the box. This replaces nested callbacks (and the commensurate error handling) with simple, familiar usage:
var orgs = await Organization.find();
# Get the latest stable release of Sails $ npm install sails -g
Upgrading from an earlier version of Sails?
awaitkeyword, instead of lower-level (and more fragile) flow control mechanisms like nested callbacks and promise chains. It lets developers breathe easier by removing the burden of painstaking, manual error handling after every database query. And best of all, it means the end of "callback hell": the most common source of bugs and stability issues in real world Node.js / Sails applications.
If ES8 isn't for you, don't worry-- Node callbacks and promise chaining are still fully supported. But for most teams, the transition to
awaitresults in sizable gains in productivity, with fewer lines of code.
Upgrade guides for all major releases since 2013 are available on the Sails website under Upgrading.
Your First Sails Project
Create a new app:
# Create the app sails new my-app
# cd into the new folder cd my-app # fire up the server sails lift

Sails actions are compatible with Connect middleware, so in most cases, you can paste code into Sails from an existing Express project and everything will work-- plus you'll be able to use WebSockets to talk to your API, and vice versa.
The ORM, Waterline, has a well-defined adapter system for supporting all kinds of datastores. Officially supported databases include MySQL, PostgreSQL, MongoDB, Redis, and local disk / memory. Community adapters exist for CouchDB, neDB, TingoDB, SQLite, Oracle, MSSQL, DB2, ElasticSearch, Riak, neo4j, OrientDB, Amazon RDS, DynamoDB, Azure Tables, RethinkDB and Solr; for various 3rd-party REST APIs like Quickbooks, Yelp, and Twitter, including a configurable generic REST API adapter; plus some eclectic projects.
For the latest core adapters and notable community adapters, see Available Adapters.

Our company designs/builds Node.js websites and apps for startups and enterprise customers. After building a few applications and taking them into production, we realized that the Node.js development landscape was very much still the Wild West. Over time, after trying lots of different methodologies, we decided to crystallize all of our best practices into this framework. Six years later, Sails is now one of the most widely-used web application frameworks in the world. I hope it saves you some time! :)
