NestJS might be the only framework that is popular among two communities i.e. JavaScript and TypeScript. The reason for its popularity is its high performance. With every passing day, this framework is gaining popularity and building a strong and active community of developers.
If you are a software developer with expertise in JS or TypeScript, you can learn NextJS as it can be highly beneficial for you. Moreover, if you plan to develop an application on Node.js, hire dedicated NextJS developers for an efficient and seamless development process.
So, whether you are developing an enterprise application or a small to mid-level project, opt for NestJS as it furnishes many perks that align with modern web development needs.
Top Benefits of NestJS
Modular Architecture
In NestJS, there is a modular architecture that enables the developers to split the application into distinct and independent modules. Every module is isolated while encapsulating relevant components like controllers, services, and providers.
The modular structure promotes code reusability and maintainability. This feature makes development easier and allows effortless scalability for complex applications.
TypeScript by Default
For your wonder, TypeScript is used to build NestJS and it offers plenty of benefits like static typing and improved tooling. TypeScript is capable of detecting errors and bugs in the early stages promoting better type safety.
Moreover, developers experience enhanced code readability and debugging efficiency. This leads to having a cleaner and maintainable code with reliable and bug-free applications.
Built-in Dependency Injection
NestJS also has Dependency Injection (DI) that manages the application’s dependencies and promotes modular design. With DI, one can define providers and inject them into the classes. This reduces the coupling between components and facilitates testing and reusability.
Scalability
Another key benefit of NestJS is its scalability. It allows developers to grow the applications effortlessly while aligning with the business requirements. The modular architecture of NestJS coupled with the support for microservices makes it easy to scale the modules of the application with ease.
Support for REST and GraphQL
Using NextJS, you will witness the sheer support of RESTful and GraphQL APIs. This offers developers a flexible environment for choosing an API type according to their needs. With REST, developers are furnished to promptly set up traditional API endpoints, while GraphQL comes into play where complex and precise data fetching is required.
Highly Testable Code
NestJS highly emphasizes testability via performing unit tests, integration tests, and end-to-end tests. The modular design and dependency injection-like features simply isolate components and allow the developers to mock services and dependencies effectively.
Additionally, the framework comes with built-in testing features that reduce the setup required for testing and ensure better code quality.
Exception Handling
There exists a comprehensive and extensible exception-handling mechanism in NestJS. The NextJS developers are equipped to craft custom exception filters that handle different types of errors efficiently.
Extensive Documentation and Community Support
NestJS comes with comprehensive documentation and an active community. This active community of developers helps when a developer is struggling with any piece of code or functionality.
Moreover, the detailed documentation in NestJS covers all aspects of the framework that help developers find solutions for complex problems.
Backward Compatibility
The structure of NestJS supports backward compatibility. With the growth of the application, the development team tries to ensure that breaking changes are minimized. This strategy promotes easy upgradation to new versions without the need to refactor large chunks of the codebase. This also ensures long-term stability for the projects.
Conclusion
With NestJS, developers get a comprehensive and modern approach to web development that combines the power and performance of Node.js along with the structure and scalability of a modular, TypeScript-driven framework. Plus, it has a robust architecture that enables effortless integration with third-party libraries and tools. So, it is a perfect choice for developers wanting to build scalable, maintainable, and high-performing applications.
