Shoutout to the tech startups and developers looking forward to going into a coding adventure! Buckle up as first we are going to explore the world of Node js web app programming! If you have a brilliant idea that will bring revolution in the tech world then you must have a strong backend to bring your idea to life. Enter Node js, a secret recipe that’s going to make your dreams a reality. But remember that its own good and bad which will be discussed in this blog post.
But let first begin with the most asked question: what is node js?
What is Node Js?
Node js is a platform for developers that allows them to develop applications using JavaScript. It is the most popular language for creating real-time applications. Since its existence, it has been an ideal choice for web development. It is an open-source environment, based on Chrome’s V8 javascript engine and written in and C/C++. It is used for server-side operations.
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 improvement in cost and performance after implementing Node js architecture.
- 42.73% of professional developers prefer using popular Node js frameworks, tools, libraries, and IDEs for app development.
- 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 to use Node js is a common concern and the answer is quite simple because there are several advantages of Node js. Node js is undoubtedly the best one to opt for among the most popular programming languages. 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 most notable benefits of Node js is its speed, which makes it the most suitable choice for most applications. It works like a superhero as it can handle several jobs at once without getting tired. Moreover, 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 slow 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
Node js is also known for its high productivity so it is also a major advantage 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 to create highly interactive websites.
4. Error Handling
The advantages of Node js 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 can be captured by your codes.
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 nodejs 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 web 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
1. Asynchronous Programming Model
It is an Asynchronous programming model while in synchronous programming tasks are carried out one after other, in a sequential way. On the other hand, Node js is an asynchronous programming model 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
Unstable API is the one that can be changed at any time. This may cause a problem for developers who want API to remain constant to maintain their software. This can result in software that is difficult to maintain. So, if you are choosing 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 non-relational database does not have a relation between tables. Relational database is the most commonly used database but it can be more difficult to work with so it can create 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 as 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 using 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 focus 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 irresponsive and sluggish.
6. An Excess of Nested Callbacks
There are Tons of nested callbacks in 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 back 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, Node js has its advantages and disadvantages 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.
