Top NestJS Agencies

NestJS is a TypeScript framework for building scalable server-side applications on Node.js. It provides modules, controllers, providers, dependency injection, guards, pipes, interceptors, and other architectural patterns that help organize larger backend systems. NestJS can run on Express or Fastify and is commonly used for REST APIs, microservices, authentication systems, and enterprise applications. Its structured approach is useful when several developers need consistent patterns across a growing backend codebase.

For projects using NestJS, teams should consider the application's requirements, expected scale, integration points, deployment environment, testing approach, and long-term maintenance. Choosing the technology should also take into account the existing skills of the development team and the libraries or services already used by the product.
