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
