Considering this factor, the Merehead team places great emphasis on developing applications based on Node JS. Therefore, we know what this runtime environment can provide and how to use it correctly. What is Node JS
Node JS is a server-side runtime environment for building SaaS web applications
. One of the key ideas of this technology was the development of a system for creating websites with the possibility of two-way connection (client and server) and free data exchange.
It uses an event-oriented I/O model, which makes Node JS extremely efficient and increases the scalability of the application. This technology is actively used in the development of applications for use in real time, the sphere of the Internet of things and microservices.
• fills the gaps between the front-end and back-end developers teams, increasing the effectiveness of the development itself;
• large package management system significantly improves performance.
Myths and truth about Node JS
Node JS has many facts, some of which are true, while others mislead users.
• it is a framework (as already mentioned, in fact it is a runtime environment, which implies a wider range of possibilities);
• it is single-threaded (in fact, Node JS can execute several sets of instructions in parallel, and single-threaded mode is started only for processing data using JS code);
• relies only on Chrome V8 (in fact, this engine is the best today, but there are also alternatives).
• is not limited to work inside the browser;
One of the advantages of Node JS is the enhancement of the JSON data exchange format, which is much more convenient for reading and writing for both a computer and a person. Today, this standard has been adopted by companies like Facebook, Pinterest, Reddit and Google.
The last interesting and truthful fact is that the NPM (Node Package Manager) is the largest package management system in the programming world. This shows how wide opportunities developers have and partially explains the popularity among large corporations.
How we use Node JS
Node JS is a very praised technology, but even it is not all-powerful. This runtime environment is ideal for most of the required applications on the site. We perform tasks of any nature, but the experience of the Merehead team allowed us to highlight several areas where Node JS shines.
Chats. One of the tasks of creating Node JS is to provide the ability to develop web projects
for processing requests in real time. Therefore, this runtime environment has performed very well for developing applications that are responsible for the work of chats. Node JS and Knockout framework
allows you to easily support large traffic, intensive data transfer and parallel communication with a large number of clients.
Monitoring dashboards. The site does not exist without collecting data about visitors, registered users and other activities. Node JS is good again because it can process a large amount of information in real time. In other words, it provides instant access to user statistics and their actions.
Streaming data. Node JS allows you to significantly speed up data retrieval or sending it to the user, because HTTP requests and responses are usually data streams. So, for example, this technology allows you to process files directly during the download process. This can be useful when adding audio / video components that take a long time to add. Also you can choose Meteor framework
Why companies choose Node JS
Each technology will mention several reasons why it is worth choosing it for application development. Therefore, today the choice of a specific development environment or implementation is rather complicated. But why did the big brands choose Node JS, and who exactly made this choice?
When you need to make an online payment, most people remember Paypal first. This platform allows you to make quick transactions over the Internet in more than 100 currencies. Today the service has more than 200 million active accounts. To create web applications, they used Node JS. Why?
Paypal senior director of payment products, Jeff Harrell, said: “Node JS solved the border problem between the browser and the server. Due to this, our specialists have become a single team. This allows you to understand the needs of customers and respond to their requirements as soon as possible”.
One of the largest streaming video providers in the world, including movies and TV shows, available in almost 200 countries. As of the end of 2018, there were about 139 million subscribers. The entire user interface is built on Node JS. According to employees, this technology has proven so effective that the company wants to use it at other levels of development.
When they approached the choice of Node JS, one of the key tasks was to achieve easy access to content and quick launch of various processes by users (loading, discussion, download, etc.). As a result of Node JS, web application launch time was reduced by 70%.
Well-known worldwide transport company, which has greatly improved the implementation of travel, changing the idea of a taxi. Uber was one of the first corporations to fully incorporate Node JS into its system.
According to employees, this technology has three main advantages: fast processing of large amounts of information; the ability to check and correct errors in process, without restarting; constant optimization. GoDaddy
Public company that deals with the registration of Internet domains and web hosting. As of the end of 2018, it had about 18 million clients and 70 million domains under management. In recent years, the entire back-end has been upgraded to a fully open infrastructure based on Node JS.
According to senior software developer Steven Commisso, Node allows you to create high-quality applications, immediately deploy new features, and easily create modular and integration tests. The second key advantage is NPM.
As a result, GoDaddy achieved the fact that they use 10 times less servers to host websites. Are you still in doubt?
If you still do not know how to increase the rating and the quality of the work of your company without suffering losses, you should try Node JS. This technology is well suited for web applications that need a stable connection between the server and the user. It is the best choice for creating interactive games, chat rooms or collaboration tools.
Node JS is a blessing for both developers and companies. You set the task, the Merehead team takes Node JS and gives you an application that will take the business to a new level.
