Technology serving the productSystems and integrations

NestJS for a backend that stays clear as the system grows.

Scalability and enterprise architecture

NestJS is a Node.js framework inspired by Angular, offering module-based architecture, dependency injection and TypeScript out-of-the-box. Ideal for apps requiring scalability and long-term maintenance.

01 / Fit

Product first. Stack second.

When NestJS is the best choice

NestJS works well in projects requiring scalable architecture and long-term maintenance.

  • Apps requiring scalable architecture
  • Microservices and distributed apps
  • Projects requiring long-term maintenance
  • Enterprise apps with multiple modules
  • Projects requiring TypeScript and type safety
  • REST and GraphQL APIs requiring structure

When to consider alternatives

NestJS has its limitations - in some scenarios simpler solutions will be a better choice.

  • Very simple APIs (better Express/Fastify)
  • Projects requiring very small bundle size
  • Apps requiring very low latency (may be overhead)

02 / Solution

Architecture and patterns

NestJS offers flexible architecture based on modules and dependency injection.

  1. 01

    Modular architecture

    Division into modules, controllers, services and providers.

  2. 02

    Dependency Injection

    Built-in DI container for loose coupling and testability.

  3. 03

    Decorators and Metadata

    TypeScript decorators for declarative configuration (routing, validation, guards).

  4. 04

    Guards, Interceptors, Pipes

    Middleware pattern for authentication, validation, logging, transformation.

03 / Quality

Production readiness starts before launch.

Security and quality

NestJS offers built-in security mechanisms and validation.

  • Authentication & Authorization

    Guards for JWT, OAuth2, role-based access control (RBAC).

  • Validation

    class-validator and class-transformer for DTO validation.

  • CORS and Security Headers

    Built-in support for CORS, helmet for security headers.

Performance and maintenance

NestJS offers excellent performance for enterprise apps.

  • Throughput

    High performance thanks to async/await and Node.js event loop. Can handle 10k+ concurrent requests.

  • Scalability

    Modular architecture facilitates scaling and microservices division.

  • Type Safety

    TypeScript ensures type safety throughout project, reducing runtime errors.

04 / Delivery

How we deliver NestJS projects

Our delivery process is optimized for scalability and quality.

  1. 01

    Architecture Design (1-2 weeks)

    Module design, API structure, database schema, authentication strategy.

  2. 02

    Development (8-20 weeks)

    2-week sprints, TDD, code review, tests (Jest, Supertest), CI/CD.

  3. 03

    Deployment & Maintenance

    Docker, PaaS (DigitalOcean Apps), monitoring, performance optimization.

FAQ

Questions before you decide

Is NestJS slower than Express?

In most cases the performance difference is minimal. NestJS uses Express (or Fastify) under the hood, so performance is similar. Overhead comes mainly from additional abstraction layer, but benefits in architecture and maintenance outweigh this cost.

Is NestJS good for microservices?

Yes, NestJS has built-in support for microservices through transport layer (TCP, Redis, RabbitMQ, Kafka). Modular architecture facilitates division into independent services.
