Avoiding common pitfalls

Building scalable applications is not just about adding more features or handling more users—it’s about laying a solid foundation that can grow with your project. NestJS, with its modular architecture, gives you the tools to create scalable, maintainable systems, but to truly take advantage of this power, you must think carefully about your application’s structure from the very beginning.

Before you write a single line of code, take the time to architect your solution thoughtfully. As we have seen in case study chapters, our application’s structure should evolve in tandem with your goals for scalability, not as an afterthought. NestJS’ modular design empowers you to build flexible and maintainable code bases, but this power only shines when you harness it with a solid architectural plan in mind.

To help you navigate these challenges, we’ve identified several common pitfalls developers face when building scalable...
