Meteor is a full-stack JavaScript platform for developing modern web and mobile applications.

• Isomorphic: one language to rule them all (JS): application server, web browser, and mobile device.

• Data on the wire: the server sends data, not HTML, and the client renders it.

• Reactivity: the UI seamlessly reflects the true state of the server for everyone at all times.

• Horizontal integration: Use (almost) any plugin, library, framework, package manager or architecture.

Atmosphere is developed for Meteor stack.

• Dependencies on core, e.g. DDP and Blaze
• Automagic management of non-JS files like CSS, Less, Sass, Stylus and static assets
• Take advantage of Meteor’s build system for automatic transpilation, e.g. CoffeeScript
• Strictly defined way to ship different code for client and server, enabling different behavior in each context
• Use in-built package namespacing and package global exports without having to explicitly use ES2015 import
• BUT, use NPM for anything else, especially when writing packages for non-Meteor use

Let's try it!
