NestJS
Also known as: NestJS / ネストJS
A full-featured TypeScript Node.js framework inspired by Angular's module and dependency-injection architecture. It is well-suited for large-scale enterprise API servers that benefit from strict structure.
Overview
NestJS enforces clear module-controller-service layering, maintaining code consistency in large teams. It supports REST, GraphQL, gRPC, and WebSocket transports in one framework.
Enterprise Adoption
Built on Express (switchable to Fastify), NestJS leverages the existing ecosystem while enabling loosely coupled design. Microservice patterns connecting services via gRPC or message queues are well established.
