(See [Module Long Term Support Policy](#module-long-term-support-policy) below.)** We urge all LoopBack 3 users to migrate their applications to LoopBack 4 as soon as possible. Refer to our [Migration Guide](https://loopback.io/doc/en/lb4/migration-overview.html) for more information on how to upgrade. ## Overview LoopBack is a highly-extensible, open-source Node.js framework that enables you to: * Create dynamic end-to-end REST APIs with little or no coding. * Access data from Oracle, MySQL, PostgreSQL, MS SQL Server, MongoDB, SOAP and other REST APIs. * Incorporate model relationships and access controls for complex APIs. * Use built-in push, geolocation, and file services for mobile apps. * Easily create client apps using Android, iOS, and JavaScript SDKs. * Run your application on-premises or in the cloud. LoopBack consists of: * A library of Node.js modules. * [Yeoman](http://yeoman.io/) generators for scaffolding applications. * Client SDKs for iOS, Android, and web clients. LoopBack tools include: * Command-line tool `loopback-cli` to create applications, models, data sources, and so on. For more details, see [https://loopback.io/](https://loopback.io/). ## Module Long Term Support Policy LoopBack 3.x is now in Active LTS.
