nodejs-pros-cons

In the present scenario, JavaScript is one of the most popular client-side programming languages. With a model of concurrency and no concept of a thread, JavaScript was able to differentiate itself from other dynamic languages. Node.js can be credited for this well-documented popularity. 

Node.js helped JavaScript in server-side implementations, which reduced a lot of complexity of using two different languages at both ends. Node.js also helps in building innovative server and web/mobile applications. This article discusses the pros and cons of this excellent run time environment, so that the next time you approach any Node.js development services to build your web or mobile apps, you're completely aware of what you can expect.

Advantages of Choosing Node.js


  • The main advantage is that it uses JavaScript, which is easy to learn. A basic Java programmer will find it easy to upgrade to Node.js.
  • Node.js is an open source runtime environment that supports caching of individual modules. 
  • Concurrent request handling is assisted by the asynchronous event-driven IO.
  • Both the server and the client-side uses the same piece of coding and as a result, it makes things easier for businesses to deploy the various web applications more effective.
  • Node.js has an active and vibrant community with codes shared regularly via Github, etc.
  • Being a single-threaded program, Node.js has multiple options for having a good control over run-time executions like event-loops and call-back methods.

Disadvantages of Choosing Node.js


  • The main drawback is the consistency factor. Many Node.js development companies feel that the API keeps changing at frequent intervals.
  • Node.js don't work well with relational databases.
  • Node.js requires an asynchronous programming approach for it to enhance its scalability. This has a split opinion among developers as many feel that this particular approach is more complicated than the linear blocking I/O programming. This also makes the code look messy.
  • Node.js is not suitable for large and complex web applications as it, at present doesn't support both multi-threaded programmings. 
  • Programmers find it hard to use Node.js for high intensive computational tasks. 

Final Words


In spite of the shortcomings, Node.js have abundant features that will help in creating a wide range of networking and server-side applications in JavaScript. To conclude, as a web developer, it's very essential to study both the pros and cons of Node.js to put it to use at the best of its ability.
