NestJS

NestJS is a progressive Node.js framework for building scalable enterprise server-side applications using TypeScript, dependency injection, and modular architecture.

When to Use

• Enterprise Node.js Backend Microservices: Architecture inspired by Angular with modules, providers, and dependency injection.
• Domain-Driven Modular Applications: Structuring large codebases with clear domain separation and clean layering.
• Multi-Transport Microservices: Seamlessly switching between HTTP, gRPC, RabbitMQ, Kafka, and Redis transports.
• Type-Safe REST & GraphQL Backends: Combining TypeORM/Prisma, class-validator, and auto-generated Swagger documentation.
