## What it is
LoopBack 4 is a highly extensible Node.js and TypeScript framework for building REST APIs and microservices, driven by OpenAPI specifications. It features a small extensible core with dependency injection, repositories, and components, and can generate working APIs from a single command.

## Use cases
- build rest apis with nodejs
- create openapi-driven backend services
- build microservices in typescript
- generate crud apis from data models
- expose graphql from rest apis
- connect to databases and rest/soap services from an api layer

## When to choose
- you want a batteries-included TypeScript framework for API-first development
- you need OpenAPI spec-driven REST API generation with minimal boilerplate
- you value extensibility via dependency injection, components, and repositories
- you need to integrate relational databases, MongoDB, SOAP, or REST backends

## When to avoid
- you need a minimal, unopinionated HTTP server without framework conventions
- you are still on LoopBack 3, which is end-of-life
- your project is a simple static site or frontend-only application
- you prefer lightweight frameworks like Express or Fastify with manual wiring
