Meteor (web framework)

Meteor, or MeteorJS, is a free and open-source isomorphic JavaScript web framework written using Node.js. Meteor allows for rapid prototyping and produces cross-platform (Android, iOS, Web) code. The server-side MongoDB program is the only proprietary component of Meteor and is part of the Meteor download bundle. It is possible to use Meteor without using the server-side MongoDB. It uses the Distributed Data Protocol and a publish–subscribe pattern to automatically propagate data changes to clients without requiring the developer to write any synchronization code. Meteor uses JavaScript as its primary programming language, enabling developers to use a single language for both client-side and server-side code. This approach can streamline the development process for mobile applications by reducing the need for additional programming languages. On the client, Meteor can be used with any popular front-end JS framework. Meteor is developed by Meteor Software. The startup was incubated by Y Combinator and received $11.2M in funding from Andreessen Horowitz in July 2012. Meteor raised an additional $20M in Series B funding from Matrix Partners, Andreessen Horowitz and Trinity Ventures. It intends to become profitable by offering Galaxy, an enterprise-grade hosting environment for Meteor applications.
