Pros and Cons of Node.js You Must Consider for Your Web App Development Project
The present-day business environment is predominantly hard to survive. To do so, organizations need to cover all the important aspects of app development correctly. Since the market has become so fiercely competitive, you can’t really afford to be I-am-alright-Jack.
Now along with some drawbacks, Node.js has a range of diverse and immense advantages. But before we take things forward, it’s important that we understand the basics of this framework.
What is Node.js?
When people ask about the advantages of Node.js, the one-word answer is its structure. That’s the sole reason for its creation as well as for the entire ecosystem of dedicated, open-source modules.
No matter what platform you’re building apps for, such nodes or microservices make the environment exceptionally useful for programmers. Each task is split up into different independent node paths that can seamlessly work together at the same time. This is why the server doesn’t bog up even if it’s using up high capacity levels.
To know more of its usefulness, here’s a read on understanding Node.js and its business benefits.
So, when it all comes down to using this particular runtime environment for your web app, and you have to hire Node.js developers, there are a lot of positives and negatives to consider. This read will walk you through the most significant points.
The Bright Sides of Node.js
The complete list of Node.js advantages can be long and heavy but crucial for understanding and planning your development process. And it’s important that you follow the best tips before hiring efficient developers from a top rated Node.js development company who can make the most of these benefits. Let’s go through them.
1. Easy Scalability
Each node in Node.js is based on an event. You can add as many nodes as you want to your core programming function. This essentially means you can scale vertically and include new capability paths to your core application code or horizontally to include new resources to already existing programming.
Nonetheless, scalability gives room for your web apps to grow, and that’s definitely a key benefit of Node.js.
2. High Performance and Speed
3. Great Flexibility
While in other frameworks and runtime environments, you need to go all the way back to the core programming to make any changes. But you just have to make changes in a single node in Node.js. This is such an amazing benefit not only for your initial development but for future maintenance as well.
On top of this, when you merge Node.js with JSON, the exchange of information between the web servers and client servers. Developers can also use APIs to create DNS, TCP, HTTP into the server.
4. Efficient Caching
In discussing the pros and cons of Node.js, caching certainly comes up as one of the key benefits. Node.js has an excellent capability to cache data. The requests you make to an app are cached in-app memory. As a result, when requests go through execution and re-execution, the nodes don’t get bogged down by historical data and, thus, run smoothly.
5. Access to a Single Programming Language
Moreover, other server-side languages become unnecessary. This essentially boosts the development process and enables programmers to have easy access to the back end of web apps. How exciting that would be!
6. Fast Development
These pre-packaged resources not only cut down your programming budget but reduce the overall time to market as well. This is a glaring benefit of Node.js that you can’t ignore.
7. Effective Queueing of Requests
One of the interesting features of Node.js is its capability to manage multiple requests at once. And how is it able to do this? Through providing an elective nob-block I/O system. It gives priority to the requests taking lower response time and this prioritization, in turn, helps your app run more speedily and smoothly. Such features you won’t find in other languages like Ruby on Rails or Python.
8. Large and Active User Community
If you’re opting for Node.js for your web app development, you’ll be blessed with the support of a large and active community of developers from every corner of the world. If you’re struggling with any part of the development process, you can find quick solutions from the community.
9. Easy Learnability
10. Real-Time Communication
Node.js facilitates a smooth connection between the server and the user. This implies there’s no lag between the server working on a request and the user asking for that. Node.js wholly processes a request while other runtime environments tend to break down a message letter by letter.
It’s important for you to consider the fact that Node.js supports Websockets, a leading real-time communications solution in the modern industry. This guarantees that users are always in sync with your updates.
11. Node Package Manager
Most of the Node.js packages and resources are open-source and free. Such availability comes with a security risk, but Node.js has eliminated the risks with its package manager for enterprises. The enterprise manager helps the packages operate behind the organization’s firewall and offers a private registry with high-security features. So, companies can easily replace unsafe codes, manage the views on codes, and detect vulnerabilities.
12. Cross-Platform Apps
With Node.js, you can develop cross-platform real-time web apps by leveraging platforms like NW.js and Electron. You don’t need to go through the hassle of writing separate codes for different desktop versions — Linux, Windows, and macOS.
If you hire Node.js developers, they can create dynamic web apps without expert-level knowledge in other languages. Additionally, there are many Google Chrome Developer Tools to write, build, and debug codes without any restrictions.
The Not-So-Bright Sides of Node.js
Now that you know the high-flying benefits of Node.js, it’s important to learn the stumbling blocks as well. Although the list of its cons is far shorter, Node.js, like every other technology, is not perfect. Some of its serious disadvantages that are worth mentioning are discussed below.
1. Low Performance with Heavy Computing Tasks
Node.js has its own set of benefits for being even-driven and single-threaded. But for the same reason, it struggles with executing heavy CPU-based tasks. Upon receiving a CPU-bound task in its event loop, it prioritizes the task and uses its available CPU strength to complete it. This leads to the slow processing and overall declaration of the event loop.
To fix this issue, Node.js developed the “worker threads” model in 2018, enabling developers to manage several threads at once. However, this doesn’t entirely solve the CPU-driven computing challenges.
2. Unstable API
Frequent API changes are one of the considerable downsides reported by Node.js users. Such API changes are backward-incompatible, driving them up the wall. Sadly, this phenomenon pushes them to frequently alter the access code in order to match in sync with the brand new version of Node.js API.
3. Asynchronous Programming Model
The key characteristic of Node.js has the asynchronous approach so it responds a lot to callbacks. If you have a number of pending tasks running in the background, then you could fall into what developers call “callback hell.” This will directly affect the quality and performance of your codes. This disadvantage nearly makes it tedious to comprehend and maintain codes.
4. Weak Library Support
Node.js has multiple NPM libraries and registries that are either incomplete or subpar quality or inappropriately documented. So if you’re not that experienced in developing web apps with Node.js, chances are such adequate monitoring will be difficult for you.
Only well-skilled and experienced developers from a top rated Node.js development company can execute your project successfully. Because it is open-source with a diverse pool of modules and libraries, there is a lack of high-standard coding. Programmers are often forced to look for support in common libraries for complicated tasks like XML parsing and Object-Relational Mapping (ORM), database operations, etc.
5. Lack of Competent Node.js Developers
Node.js plays a crucial role in developing high-performing and scalable web apps. Developers absolutely love experimenting with its advantages, and its popularity among them is not much of a surprise. It offers a whole package of speed, performance, and scale that empowers today’s use cases vital for web apps. The advantages of Node.js surely outweigh its disadvantages.
So, the bottom line is — if your desired web app doesn’t include heavy CPU-based tasks, Node.js is the trump card for you. Explore the market and choose a top rated Node.js development company that can leverage the benefits mentioned in this read and give the best solutions for your next web app development project.
