Which One Should You Choose NEST JS or EXPRESS JS?

Choose NestJS if:

  • You're building a large-scale, enterprise, or microservices-based application.
  • You prefer TypeScript and want built-in features like DI, validation, and modularity.

Choose Express if:

  • You're building a simple app, prototype or MVP.

  • Your team is already experienced with Express or you're integrating with an existing app.

NestJS is ideal for complex, scalable and enterprise-grade apps, 
While Express is better suited for lightweight, quick and simple projects.
