In contrast, the Spring Framework, based on Java, utilizes a multi-threading model that is more efficient for CPU-intensive tasks, potentially offering up to 30% better performance in such scenarios.
Memory Usage
Memory usage can also diverge significantly between the two frameworks. It largely depends on the complexity of the application and the underlying architecture of the chosen framework. The Spring Framework is known to consume more memory due to its large feature set. While a typical enterprise application can consume up to 200–300 MB more memory than a similar application built on a leaner framework, NestJS, due to its modular and minimalist design, can reduce the memory footprint of a similar application by up to 40%.
Development Costs
On the financial side of things, NestJS potentially offers cost benefits. Its foundation in JavaScript, a language that is familiar to about 67.7% of developers, can lead to a shorter learning curve and thus lower associated development costs if your team is proficient in JavaScript. In contrast, the Spring Javascript Framework may require more specialized knowledge. Therefore, training costs may be higher if the team is not yet familiar with Java.
Conclusions
How to choose between NestJS or the Spring Framework? It is largely contingent on your specific project needs and the expertise of your development team.
NestJS, being built on the modern and popular JavaScript, maybe a more accessible option for teams that are already proficient in JavaScript due to its leaner architecture and potentially lower memory footprint. The result is reduced resource consumption and shorter development time. Also, its single-threaded event loop model is perfect even for I/O heavy applications.
On the other hand, the Spring Framework has a robust feature set and multi-threading model, ideal for more complex, CPU-intensive tasks. Although memory usage can increase and there are costs associated with Java developer salaries, the extensive features offered by Spring are a worthwhile trade-off for certain projects.
The key to choosing between NestJS vs Spring Boot is therefore to fully understand the requirements of the project and carefully evaluate the NestJS and the Spring Framework's pros and cons. If you take this into account, you'll get a successful project outcome.
