In what situations is it advisable to avoid using NestJS in projects?

NestJS is a powerful framework for Node.js that is well-suited for building scalable server-side applications using TypeScript and architectural patterns like MVC and Dependency Injection. However, there are situations where its use may be excessive or impractical:

• Very small or simple projects. If the application is a simple API with a few endpoints, using NestJS might add unnecessary complexity.
• Projects with strict performance and minimal latency requirements. NestJS adds an abstraction layer, which can slightly reduce performance compared to plain Node.js or lighter frameworks.
• When the team is not familiar with TypeScript or NestJS architectural patterns. The learning curve can slow down development.
• If the project requires very specific solutions that are difficult to implement within the NestJS architecture. For example, very low-level network operations.

In these cases, more lightweight or specialized solutions can be considered.
