FREver wondered why NestJS relies so heavily on decorators? 🤔
Decorators are not just fancy annotations — they are the backbone of NestJS architecture. They attach metadata that helps the framework automatically configure routing, dependency injection, and application structure.
From defining controllers and mapping HTTP routes to injecting services and extracting request data, decorators make your code cleaner, more readable, and easier to scale. 🚀
Understanding decorators means understanding how NestJS works under the hood and that’s a big step toward writing better backend systems.
If you want to build structured, modular, and maintainable APIs, mastering decorators is a must. 💡
