First, let’s look at the back-end of Node.js to understand its benefits. The front-end is where most web developers are familiar for seeing websites live.
In reality, when we view a website in a browser we send a special request (called a “web server”) to another computer over the internet. The web server sends us back the exact same web pages in the form of a respective answer.
The server makes a web page by using client-side and server side software. The server is responsible to exchange, process, and store data using code that assists in processing your browser’s network requests.
Node.js enables developers to use JavaScript in order to create server-side applications, even though JavaScript has traditionally been used only in the browser for client-side development. Because both sides can be combined in the same environment, it is much easier to create web server. Node.js popularity has skyrocketed as a handy tool for creating server code.
What is Node.js and how can I use it?
Node.js allows JavaScript to be handled on the server-side by the V8 engine, as we mentioned previously. The V8, an open-source JavaScript Engine that powers Google Chrome as well as other similar browsers, provides the runtime environment needed. JavaScript runs on the client side, while Node.js scalable technology works on a computer on a server. This allows for a javascript development company to create fully-featured applications.
Node.js includes everything you need to run a JS application. This open-source framework supports many external libraries. It can also call JavaScript code commands and act as a Web server.
Node.js isn’t a programming languages like Java. It’s a technology which assists JavaScript in creating server codes. Let’s now go back in history to learn more about Node.js.
The platform was developed by Ryan Dahl, an engineer. Joyent’s sponsorship later helped to make it possible. Node.js was only 12 years of age, but it has been an integral tool in server side programming. First, the core engine Chrome V8 JavaScript was introduced. The platform also includes a low level non-blocking I/O API and an events loop.
Timing, precision and innovation were the keys to Node.js’s success. JavaScript, which was twice its age, went through many upgrades to improve its speed.
Statistic
It is hard to find a better way to understand Node.js and show its popularity than with good old-fashioned statistics.
Node.js has many benefits for new businesses. It can reduce development costs by 60%, increase application efficiency by 50% and lower waiting times by 35%.
Three years ago Node.js was able to download its first billion files.
This technology is used in more than 30,000,000 websites.
Node.js already has the benefits for a few companies such as Netflix, Amazon and PayPal. PayPal reports that their responsiveness has increased by 200ms.
This comprehensive report also includes data from US businesses mentioning a 68% improvement in developer productivity following the switch to Node.js.
What can Node.js do for you?
Node.js is most effective for the following projects (with example code):
Real-time web applications. Node.js can be used for remote collaboration such as Trello or online publishing platforms like Medium.
E-learning websites, apps. Quizlet is a good example of Node.js adding extra responsiveness to the platform and speeding up its development.
Both e-commerce and online payments tools require more advanced functionality. For example, eBay and PayPal.
Chats and other messaging applications. These multi-user and real-time applications, which are both lightweight and can handle high traffic, are great for Node.js. Below is a tutorial and an example of real-time Chat using NodeJS, ExpressJS, and Socket.io.
Internet of Things devices with lots of requests — sensors, wearable solutions. Here is the code to control a Node.js vehicle-controlling IoT system using your smartphone and wifi.
Social media. Node.js can also be used by social media apps. These apps must be safe, lightweight, flexible, and always updated. LinkedIn and Twitter are some of the most prominent examples.
Multiplayer games and virtual emulators benefit from the platform’s fast response times. It’s easier to communicate with large amounts of players and execute multiple scenarios. Here are a few Medium examples.
Based on what tasks are being performed, Node.js is recommended.
To create a collaboration system with streaming capabilities
Your app should be capable of handling high traffic and/or intensive video buffering
To create different nonconcurrent app function functions that don’t need to connect with the CPU
To develop an efficient single-page application, like Gmail
A solution with higher scalability is required
To do remote presentations or video chats
If you are looking to build and implement microservices
Node.js:
Despite the amazing things Node.js has to offer, there are still a few areas in which it’s not a good idea.
You can do heavy-duty server-side processing. Node.js’s non-blocking input/output design means that you won’t have to build anything CPU-intensive.
Already simplified apps that only use a handful of functions. Technically, Node.js could be used but it would not do any good. It would just make it harder to use, so it’s better to use something simpler.
Applications that use relational data acces. Node.js isn’t the best choice for backend database needs because it lacks the necessary capacity to run correct backend computations.
What are the pros and cons about Node.js?
Node.js, like any technology, has its strengths and weaknesses. These depend on the project and the resources that you use. The following table will help you determine whether this platform is the right one for you.
Node.js benefits
These are the advantages of this backend platform
Simplicity and cost efficiency. One language for client and server reduces switching back and forth between front-end and backend. This means you won’t need multiple teams for a project.
Rapider development due to shared and reused codes, JSON support, various tools and a smaller stack of files that are required to complete the application.
Scalability is commonly referred to as the No. 1 benefit of Node.js. It’s not surprising. Businesses that want to grow quickly will appreciate the load balancing feature and the tool’s ability to handle multiple parallel connection.
Event-based models allow for rapid synchronization. They provide real-time updates and also perform secondary tasks in a background.
An active community. Node.js and JavaScript are supported. Any issue that isn’t addressed by previous experience can be solved with the help of plenty of feedback and various internet resources.
Higher rate of adaptation due to the easier and quicker learning curve, especially for JavaScript’s partner. This is also a benefit for customizing due to the built-in API.
Node.js has many advantages, such as a faster loading time and a direct caching option.
It is possible to develop a minimum viable product (MVP), faster. Although it may not be a full-fledged solution, it does have enough functionality that it can be effectively presented on the markets.
Node.js makes it easy for developers to separate their projects by using microservices. It then helps to efficiently divide tasks among team members.
The ability to create a cross-functional group with improved internal communication and productivity rather than an average functional group where expertise is defined and function overlap is frowned upon.
Drawbacks and possible disadvantages
Although Node.js offers many benefits, there are still some issues that need to be addressed.
Lack of stability in the Application Programming Interface. It sometimes forces developers to change accessible codebases to blend with the latest API version when it suddenly changes at rapid intervals and is also backward-incompatible.
There may be occasional obstructions in performance flow with heavy CPU-based computation. This is due Node.js being singlethreaded and something special worker threads modules are unable to fully resolve.
Node.js asynchronicity makes developers rely on callbacks. They then stack on nested structural within other callsbacks. This makes understanding and maintaining the code difficult.
The gap between current demand, the real number of Node.js specialists on the marketplace and the fact the not all JavaScript developers are able to quickly master backend server-side is despite popular belief.
Node.js development: Prospects and trends
Node.js should only increase in popularity according to recent market reports and trends. Node.js today is about static typography and design patterns like dependency injection. The result is that a JavaScript project, with its simplicity and ease, will be easily replaced by the robustness of Node development and its support when working in large projects.
Node.js is a mature platform that has seen significant growth over the last few years. With the help of the expert community and solid tools to debug, trace and identify other problems, Node.js has grown significantly. Microservices can be used to replace static typing, while reducing its complexity.
Node.js currently has a bright future as it is one of most highly sought-after backend platforms. There is still much to be done, and fewer questions are being raised about Node.js.
Why use Node.js development?
This question may not be as important as it used to be. According to the third annual Node.js User Survey, respondents described the following impacts on their business:
