NestJS est un framework open source pour Node.js, écrit en TypeScript et distribué sous licence MIT, créé en 2017. Il sert à développer des applications côté serveur, comme des API REST, des services GraphQL ou des microservices. Son architecture repose sur des modules, des contrôleurs et l'injection de dépendances, et il s'appuie par défaut sur Express, avec Fastify en alternative.
