Questions tagged [loopbackjs]

LoopBack is an open source Node.js framework built on top of Express.js optimized for mobile, web, and other devices. Connect to multiple data sources, write business logic in Node.js, glue on top of your existing services and data, build REST APIs and connect using JavaScript, iOS, and Android SDKs.

The LoopBack framework is a set of Node.js modules that you can use independently or together. An application interacts with data sources through the LoopBack model API, available locally within Node.js, remotely over REST, and via native client APIs for iOS, Android, and HTML5.

Using these APIs, apps can query databases, store data, upload files, send emails, create push notifications, register users, and perform other actions provided by data sources and services. Clients can call LoopBack APIs directly using Strong Remoting, a pluggable transport layer that enables you to provide backend APIs over REST, WebSockets, and other transports.
