What is NodeJS suitable for?
With NodeJS, the development process becomes simplified and the performance gets a lift. As it is capable of tackling multiple requests and you can smoothly scale it, it is also a great choice for API building.
Key Business Applications Of NodeJS
Currently, around 0.4% of the websites with known web servers are using NodeJS. Among these, popular sites are Healthline.com, Dictionary.com, and Flickr.com. Have a look at the key business benefits of the various applications of NodeJS.
- Written code is compatible with multiple platforms
- You can execute it locally, and NodeJS is easy to install
- Rapid MVP (minimum viable product) delivery
- Great performance
- Fast native buildings
- The tight connection between server and client
- Goes well with open source modules and packages
- Cloud scaling
- Cheap hosting
- Lightweight service
Reasons Why NodeJS is a must for Backend Web Application Development
When choosing the back-end development technologies — NodeJS stands as an ideal option as it holds the great majority of contemporary business domains as well as real cases.
This means the time and effort required to learn and work automatically get reduced.
Walmart, LinkedIn, Uber, NASA, and some other huge entities have used this open-source, straightforward, and easy-to-customize environment for their web applications.
Advantages Of Using NodeJS For Web Application Development
The developers have already used NodeJS in more than 96,819 domains and 187,467 websites. As per data from SimilarTech, Node JS is most popular in the US – almost 36,000+ websites use it. The fast suit and easy coding features of NodeJS are among several factors leading to this rapid integration. Here are some of the advantages of using it for the development of web applications.
1. Real-time Apps For Your Business
2. Streaming Data
The app builders consider the request and response of HTTP in web app development to be separate events. These are actually data streams and one can use the function along with Node JS to come up with great attributes. For instance, these may include cutting down the overall process duration, processing files simultaneously while loading, and so on. These can be implemented when an audio or video is recorded in real-time.

With a greater number of web app developers demanding Node JS for their projects, hosting has gained impetus to a significant extent. Platform as a Service (PaaS) service providers like Heroku and Modulus are officially permitting node deployments without any issue. Apart from this, it includes an open-source community, delivering outstanding modules, that make NodeJS applications more powerful. Among these Socket.io is a popular module handling constant interaction between the server and the client. The server can send real-time updates through push notifications to the clients.
4. Increasing Productivity
Disadvantages Of NodeJS
1. Unstable API
One of the most significant downsides reported by NodeJS users is the frequent API changes. At times, a new API appears to have a number of backward-incompatible changes. Unfortunately, this forces them to frequently change the access code to match in sync with the newest version of NodeJS API.
2. More Development Time
The point that NodeJS is without any strong opinion can also be seen as a downside by some developers. Ruby on Rails runs you with a lot of guidelines from a new install as well as guides you into their way of doing things, but with NodeJS you need to write all from scratch. It might outcome in shrinkage in productivity.
3. Not Suitable for Heavy-Computing Apps
Whenever a heavy request comes to the event loop, NodeJS would set all the CPU available to process it first, and then answer other requests queued.
That outcomes in slow processing as well as inclusive delay in the event loop, which is why NodeJS is not recommended for heavy computation.
4. Immaturity of Tools
As NodeJS is mostly an open-source ecosystem, numerous tools have not been supervised and so they might lack the quality and fail at meeting coding standards. Npm’s structure makes it harder to spot reliable packages.
5. Callback hell issue
Due to its asynchronous nature, NodeJS depend heavily on callbacks, the functions that run after apiece task in the queue are finished. It’s a situation where callbacks are nested within other callbacks several levels deep, potentially making it difficult to understand and maintain the code.
6. Lack of Library Support
As a result, users are forced to require the support of a common library for executing various tasks like Object-Relational Mapping (ORM), the process of the pictures, handling database operations, and XML parsing, etc.
