## What it is
LoopBack is a highly-extensible Node.js framework for building dynamic end-to-end REST APIs and microservices with model-driven development, built-in data connectors, and access controls. This repository hosts LoopBack 3, which has reached end of life; users are urged to migrate to LoopBack 4, the current TypeScript-based version.

## Use cases
- build REST APIs from database models with little coding
- connect Node.js apps to MySQL, PostgreSQL, MongoDB, Oracle, or SOAP services
- add model relationships and access controls to APIs
- generate client SDKs for Android, iOS, and JavaScript apps
- scaffold Node.js API projects with a CLI
- expose REST APIs as GraphQL interfaces

## When to choose
- maintaining an existing LoopBack 3 application
- learning how LoopBack 3 works before migrating to LoopBack 4
- you are an IBM API Connect customer with support entitlement

## When to avoid
- starting a new API project - use LoopBack 4 instead
- you need community support or new features for LoopBack 3
- you want a lightweight minimal HTTP framework without model-driven conventions
