Modular architecture
Scalable & secure
Why choose NestJS?
NestJS is a progressive back-end framework built on top of Node.js and TypeScript. It combines the speed of JavaScript with the structure of a framework such as Angular, including dependency injection, modules, decorators, and powerful CLI tooling.
This makes it ideal for building complex APIs, microservices and server-side applications with a structured, scalable architecture. NestJS also integrates seamlessly with modern standards such as GraphQL, WebSockets, CQRS and OpenAPI.
For organizations that focus on sustainable software, NestJS is the logical choice.
NestJS at Thesio: scalable back-ends with vision
At Thesio, we use NestJS for everything from simple REST APIs to complex, event-driven microservice architectures. Thanks to our in-depth knowledge of TypeScript, Node.js and software design principles, we build back-ends that are not only efficient, but also easy to maintain and expandable.
We use best practices such as Domain Driven Design (DDD), hexagonal architecture, and module-based structures. In addition, we integrate tooling such as Swagger (API docs), TypeOrm/Prisma, Redis, RabbitMQ, Kafka or PostgreSQL — depending on the use case.
Our back-ends are CI/CD ready, optimized for performance, and set up securely.
Structured building for the future
Unlike minimalistic Node.js setups with Express, NestJS offers immediate structure and maturity. This ensures faster development speed, better collaboration in teams and easier onboarding.
For scale-ups, platforms and enterprise customers, this is the foundation for sustainable growth. And with full support for microservices, messaging, and GraphQL, NestJS is ready for any scenario. We ensure that your back end can keep up with the pace of your business.
Frequently asked questions about NestJS development
Express is minimalistic and flexible, but lacks structure. NestJS builds on Express and adds powerful features such as dependency injection, modules, decorators, and native TypeScript support. This makes it more suitable for larger or more complex projects.
Yes, NestJS has full support for microservices, including message brokers such as Redis, RabbitMQ, or Kafka. It also offers support for event-driven architectures and distributed systems, including out-of-the-box patterns.
Sure. NestJS is popular among enterprise teams because of its scalability, structured approach, extensive testing options and full TypeScript support. We use it for everything from back-end APIs to service layers within larger platform architectures.
