What is Node.js?
Node.js is a runtime environment for developers that allows them to develop applications using JavaScript. JavaScript is the programming language used with Node.js. Think of Node.js as a platform that allows you to run JavaScript on the server side. It is a single-threaded, open-source, cross-platform runtime environment for developing fast and scalable server-side and networking applications. Since its existence, it has been an ideal choice for web development. This open-source environment is based on the Chrome V8 javascript engine, and it also uses event-driven non-blocking I/O architecture, which makes it a suitable choice for real-time applications.
Web Development with Node Js
Web development with Node.js means creating web applications using Node.js as the primary backend technology. In Node.js website development, developers use JavaScript, a client-side scripting language, to create the server-side logic of web applications. It provides a run-time environment that allows developers to execute javascript code on the server side, outside of the web browser. This results in a huge range of possibilities to develop high-quality, efficient, and real-time web applications.
Statistics of Node Js
- More than 6.3 million websites are using Node.js, in the United States, it is the most widely used tool for website development.
- Companies like Netflix and Paypal have observed significant improvements in cost and performance after implementing Node.js architecture.
- As per Statista, 42.73% of professional developers prefer using popular Node.js frameworks.
- Almost 42.07% of seasoned programmers also use Node.js as their go-to for web application development projects.
- The market share of Node.js is around 1.11% in the programming language.
But still, everything has its good and bad side, and this is also the case of Node.js so, let’s look into the Node.js pros and cons.
Advantages and Disadvantages of Node Js
Advantages of Node.js
1. Strong Technology Stack
Why use Node. js is a common concern, and the answer is quite simple because there are several benefits of Node.js for web development. According to W3Techs, Node.js is used by 3.1 percent of all websites. So, by using Node Js, you can leverage all the advantages like better efficiency, overall productivity, code reuse and sharing, easy sharing of knowledge with teams, and a greater number of free tools.
2. Fast Speed
One of the notable benefits of Node. js is its speed, which makes it a suitable choice for most applications. It works like a superhero as it can handle several jobs at once without getting tired. It does not wait for one task to be complete to start the other, as it can manage them simultaneously. It means that your website or application can perform several tasks at once. It allows your website or app to serve multiple users without getting slowed down.
Node.js uses non-blocking I/O, which makes it a super fast multi-tasker. So when Node.js starts processing, it doesn’t wait for one request to complete before moving to the next. It helps your website or applications run smoothly even when it’s super busy.
3. Enhanced Productivity
High productivity is also a major benefit of Node.js; that’s why it is recommended for developing web applications. It is ideal for real-time applications like chat and video streaming because it is a single-threaded, event-driven environment. Its high productivity makes it an ideal choice for creating highly interactive websites.
4. Error Handling
The benefits of Node.js for web development include its capability to handle errors effectively. The error-handling mechanism in Node.js allows you to identify the errors in the run time so that you can do something about it. It is much easier in Node.js to capture the errors as they are thrown as events that your codes can capture.
5. Cost- Effectiveness
Count cost-effectiveness as one of the major advantages of Node.js. Choose Node.js as it is the most cost-saving and time-saving approach. It helps in saving the cost in multiple ways:
- It lowers the IT cost by lowering the amount of hardware required for server requirements.
- It decreases the operating expenses related to software licensing.
- It eliminates the maintenance cost related to upgrading existing applications.
6. Faster Development
Faster development is a prominent node.js advantage so If you want your app or website to be super fast then Node js is the most appropriate choice you should opt for. Node.js for web development allows developers to create applications or websites in a much shorter period than other platforms and languages such as Java or C++. It makes it easier for you to launch your products more quickly while maintaining the quality of the application as well.
Disadvantages of Node Js
While having multiple advantages, Node.js has a few disadvantages as well. So, let’s have a look at the disadvantages of Node.js.
1. Asynchronous Programming Model
The first disadvantage of Node.js is that it is an Asynchronous programming model while in synchronous programming tasks are carried out one after the other, in a sequential way. On the other hand, Node.js is an asynchronous programming model, which means the tasks do not depend on each other and can run simultaneously without waiting for others to complete them. So, different tasks run independently, allowing for better efficiency and speed.
2. Unstable API
An unstable API is one that can be changed at any time. This may cause a problem for developers who want the API to remain constant to maintain their software. This can result in software that is difficult to maintain. So, if you are going for Node.js web development, then be careful, as the API is unstable, and your code can be broken at any moment if you are not cautious.
3. Dealing with Relational Database
A relational database stores data in the form of tables, each table consisting of rows and columns. On the other hand, a non-relational database does not have a relation between tables. A relational database is the most commonly used one, but it can be more difficult to work with, creating a problem for developers.
Node.js is suitable for working with relational databases. If you want to work with a relational database like MySQL, there is a special tool called MySQL module that helps you to connect to and manage your database. But sometimes, using relational databases with Node.js can be quite challenging.
4. Limited Library Availability
Node.js for web development does not have a strong library support system, which is also a considerable disadvantage of Node.js. It contains fewer high-quality libraries as compared to the other programming languages. This may give you a tough time finding the right library for the given task, making it challenging to start development with Node.js. Unlike other programming languages, the libraries of Node.js do not have all the features you might need. So, if you’re a developer, you are ready to encounter this problem as you may face difficulty in carrying out even simpler tasks, leading to more bugs and errors when your code goes live.
5. Decreased Performance under Heavy Computational Tasks
One of the biggest disadvantages of Node.js is that it cannot perform heavy CPU-bound tasks. When Node.js gets the biggest task to be done, it requires a lot of CPU power. Node.js focuses on doing that task first before moving on to handle the other requests waiting in line.
What do you understand from that? Look, it means that Node.js uses most of the CPU’s power for that task, which in turn makes everything else in the application slow down. This can make the overall process unresponsive and sluggish.
6. An Excess of Nested Callbacks
Nested callbacks are also a disadvantage of Node.js. Confused? Let us explain to you more clearly. So, look! Callbacks are like instructions in Node.js that tell what to do after a certain task is done, letting other tasks happen. But when there are lots of tasks in the line with their callback, then things can get confusing, which calls callbacks hell as the callbacks are nested inside each other, making the code hard to understand and fix.
Conclusion
In wrapping up, there are several pros and cons of Node js for developers. As far as the advantages of node js are concerned, it provides speed, productivity, and cost-effectiveness. These advantages make it a top choice for developing web applications. In contrast, it also presents several challenges like asynchronous programming and limited library support. Regardless of these drawbacks, Node js is still a powerful tool for tech startups aiming for efficiency and innovation in web development projects. Developers can make informed decisions by understanding its strengths and weaknesses.
