FAQ
Frequently asked questions about NestJS Development
Why NestJS and not Express directly?
NestJS adds enterprise structure on top of Express (or Fastify): modules, dependency injection, validation with pipes and automatic documentation. For medium and large projects, this structure saves time and reduces errors.
Does NestJS work with SQL databases?
Yes, NestJS is database-agnostic. We work with MongoDB (Mongoose), PostgreSQL (TypeORM/Prisma), MySQL and any database according to your project needs.
How much does a NestJS backend cost?
A NestJS backend with authentication, CRUD and validation starts from 4,000EUR. Enterprise systems with microservices, queues and payments can reach 20,000EUR or more.
Can I combine NestJS with Angular?
Yes, it is a perfect combination. Both use TypeScript, decorators and a similar module-based architecture. Sharing interfaces and types between frontend and backend accelerates development.
Do you offer NestJS API maintenance?
Yes, we offer maintenance plans with dependency updates, monitoring, bug fixes and new feature development.
