With plenty of available options, choosing the right backend technology for application development is one of the toughest decisions that an organization has to take these days. How fast the application can be delivered, what will be the probable total cost for development, whether the application maintenance will be a big pain for you or not, etc. factors depend on which tech stack you are choosing for the backend development.
The moment Node.js came into the picture, in no time it became one of the favorite backend technologies to the developers and programmers worldwide.
If you hire Node.js developers, you will get the best web development services that are extremely helpful to build real-time and data-friendly applications that work in different environments.
Now, if you are thinking that you should hire Node.js developer for your next project, knowing both its good sides and bad sides will help you to take the most optimized decision for your project development.
In this article post, you will find a list of the pros and cons of using Node.js for application development.
To handle multiple concurrent clients, it offers options like event loops and call-back methods. Thus, it helps in diminishing the wait time in the server’s process.
Node.js allows two types of scaling. Vertical scaling allows you to add more resources to a single node. And the Horizontal scaling allows you to add more nodes to your existing system.
The inbuilt APIs offered by Node.js allows the developers to create different types of servers including TCP Server, DNS Server, HTTP Server, etc.
Also, using it, you can easily develop RESTful API services.
Caching of modules is supported by Node.js. A Node.js module is cached into the application memory the first time it is requested. So, the next time it is called, it does not execute again.
Other than all the above-mentioned benefits, Node.js is an open-source technology and has vast community support.
Even though Node.js has a lot to offer, some points that make you have second thoughts on using Node.js for your application development.
As Node.js is a CPU-intensive operation, it has turned out to be a bad choice for heavy computation. many developers and coders find it difficult to use this runtime environment for computationally intensive tasks.
Compared to other available programming languages, Node.js lacks in having a strong and robust library support system. To execute tasks like image processing, database operation handling, XML parsing, Object-Relational Mapping, etc., Node.js developers have to take the support of the common library. And it makes it difficult for them to implement the most common programming tasks.
Inconsistency is one of the biggest issues with Node.js. The APIs change frequently. And unfortunately, often these changes are backward-incompatible. This is why Node.js experts have to struggle to change the accessible codebases to make it compatible with the latest Node.js API version.
When the scalability of an application is the main concern, you are bound to use the asynchronous programming model. Now, the developers who are more familiar with the linear blocking I/O programming, find it difficult to work with this asynchronous programming model.
Also, in the case of asynchronous programming, the coders have to depend on the nested calls and the codes tend to become a bit clumsy.
According to a survey among the developers, they are cheering more for this technology rather than complaining about its disadvantages. So, if you are confused about whether to opt for it or not for the development of your application, it is better to get in touch with a trusted web app development company and consult the experts. They will guide you in the right way.
