Pros of Node.js Development

There are many advantages of node js which are why JavaScript developers use it. Moreover, various enterprises want web apps in this technology. Scroll down to know the benefits of using node.js.

  • Non-Blocking I/O Model
  • Fast Code Execution
  • MVP Development
  • Scalability
  • Robust Technology Stack
  • Large Community



  1. Non-Blocking I/O Model: The non-blocking I/O model of Node.js makes real-time applications clean and ideal. It enables a single process to serve multiple requests simultaneously. I/O model reduces the execution time and gives high performance. It is one of the best node js advantages that helps the developers to build user-friendly web apps.
  2. Fast Code Execution: The Node.js developers have to write 33% less code. It helps them to create web apps fast and effectively. Shortcodes lead to fast execution and the developers can work on the improvements in the app in the remaining time. Consequently, they can optimize the errors to avoid them.
  3. 3. MVP Development: If you hire Nodejs developers, you can have powerful and robust web apps. It is because the developers can make Minimum Viable Products. It helps to find out how the market will react to your business idea early. So, you can know what improvements can help the app.
  4. Scalability: Node balancing in Node.js makes it scalable. This means it can handle various Nodes at the same time and reduce waiting time. It is because all APIs of Node are programmed in a way that they support callbacks. This is one of the important advantages of node js.
  5. Robust Technology Stack: Node.js is a part of the MEAN and MERN stack. It includes a robust technology stack that helps the developers at every stage of development from building an app to its deployment. Node.js has around 368,985,988 downloads. So, since JavaScript is a leader among the programming languages, Node.js is the great choice for robust technology stack.
  6. Large Community: A large community supports Node.js if there is any flaw. Moreover, brings updates on a regular basis, Node 17 is a current version. Feedbacks by the community also accelerate the development speed. Likewise, a Node package manager (NPM) is the fastest and the largest software industry in the world. A Node.js web app development can work effectively because of the large community support. These are the Nodejs advantages. Now you must have understood why you should pick Node.js for your app or website development. But there are some limitations of this JavaScript engine. So, you should know the advantages and disadvantages of node js as well.



Cons of Node.js Development

Although Node.js is supported by a large community and an engine of popular language (JavaScript), it still has some limitations. Have a look at them below so that you can make the right decision for your app or web development.

  • API Is Not Stable
  • Lacks a Strong Library Support
  • Few experienced Node.js Developers
  • Bottlenecks
  • Slow CPU Bound Task
  • Asynchronous Programming Model



  1. API Is Not Stable: 
    Frequent API changes are a drawback of Node.js. Because of unstable API developers face several issues. They have to change the access code to match with the new version of Node.js. Likewise, it is important to change the code otherwise, the developers can’t make the code compatible.
  2. Slow CPU Bound Task: Node.js is called single-threaded because it follows the processes of JavaScript. The Non-blocking I/O uses an event loop and processes the threads asynchronously. So, many developers believe that Node.js is not a good choice for apps that need heavy computation.
  3. Lacks a Strong Library Support: Unlike many programming languages, JavaScript has no strong library support. The lack of well equipped and robust library system in Node.js forces the developers to use a common library to execute various tasks like object-relational mapping, handling database operations, and more.
  4. Few experienced Node.js Developers: The growing demand for Node.js app development is facing issues due to the lack of Node.js professionals. Many developers have only a few years of experience in Node.js and this is one of the crucial disadvantages of Nodejs. Our Node.js development company has experienced developers to help you.
  5. Bottlenecks: Node.js is not able to perform CPU-bound tasks. Moreover, JavaScript uses a single thread to process tasks on time so Node.js. Resultantly, whenever the heavy requests come to the event loop it follows CPU issues and then handles requests. Consequently, slow processing and delay in the event loop occur.
  6. Immature NPM Module Registry: Node.js has thousands of open source modules due to large community support. Consequently, often developers get confused whether the program they are using has a proper registry and is completed or not. So, these are some important advantages and disadvantages of using Node. Read them properly before you hire a Node.js development company. Node.js is popular in the US and more than 6 million websites use it. This fact shows the boost in web app development is also obvious. But, often cost of Node.js development becomes a hurdle. So, we decided to give an idea of cost as well.
