Why Loopback 4:

  • A brand new LoopBack core to deliver great extensibility and flexibility written in TypeScript/ES2017.

  • You can Create powerful APIs easily with a new creation experience for defining REST API's and handling API requests/responses.

  • A new, improved programming model with Dependency Injection and new concepts such as Components, Mixins, Repositories, etc. make this the most extensible version yet.

  • Using OpenAPI-to-GraphQL, create a GraphQL interface for any REST API

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 major relational databases, MongoDB, SOAP and REST APIs.

  • Incorporate model relationships and access controls for complex APIs.

  • Separable components for file storage, third-party login, and OAuth 2.0.
