In the Fintech industry, solutions based on Node.js are also used by Citibank and Revolut (here it is specifically Gatsby).
Twitter has also switched from Ruby on Rails to Node.js in its application. Like LinkedIn, it took advantage of the speed of the new app and resource savings.
Node.js uses, i.g. Netflix. Thanks to it, the company created the user interface of a mobile application in JS. Again, speed and saving of server resources were of paramount importance. The application turned out to be light and modular in structure.
The advantages of Node.js in video streaming were also important to Courseo, which built their application on the environment.
Node.js is great for creating real-time applications, including chats. Important here are, among others, quick notifications and the ability for multiple users to collaborate and interact. With Slack, which built an app based on Node.js, speed was also important, as was responsiveness.
Node.js was used to build the application by Trello. Service is a comprehensive task management tool with an intuitive interface in its app. Node.js allowed for quick real-time changes and updates thanks to its event-driven approach
Node.js was also used by one of the e-commerce leaders, eBay. With the environment, the company built an application that worked efficiently in real time and supports many services. EBay also appreciated the speed, simplicity, single-threading and scalability of Node.js.
The smooth operation of the applications in real time makes Node.js increasingly used in the world of the Internet of Things. Applications are extremely fast and scalable and can handle plenty of devices simultaneously. Node.js enables the processing of large amounts of data and efficient communication between devices and servers.
Incoming requests are executed quickly, and the application will consume significantly less RAM. It will also be more scalable and efficient.
Every time the application module receives a request, it buffers it. As a result, users get instant access to the website.
Your developers can count on the support of the Node.js development community. For example, they will find many ready-made solutions and codes in GitHub, which will facilitate and speed up their work. In case of problems, they can look for answers in many forums.
When deciding to hire a Node.js developer, pay attention to whether he has the following features and skills:
It’s obvious, but when choosing a Node.js developer, you should remember that he has already implemented projects with the participation of this environment. Theoretical knowledge is not enough. An ideal candidate would also be an active member of the Node.js community, as it would mean that he is interested in the operation and development of the solution.
Although work with Node.js is server-side, the candidate should be familiar with the tools of front-end specialists. This includes knowledge of such languages as HTML5 and CSS3. He should also know how to build software based on mockups.
Frameworks are sets of tools that speed up and facilitate the work of a programmer and extend the functionality of the solution. A Node.js specialist should know first the Express framework. It is good for him to be familiar with solutions such as Koa.js or Total.js, which increase the capabilities of Express. Knowledge of MVC frameworks, such as Strongloop, Sinatra, Rails and Meteor, will also be beneficial.
APIs allow integrating different systems. This can make working with Node.js a lot easier. Therefore, the candidate should be well versed in the RESTful API to adapt the interfaces to the needs of his project.
The developer should be able to handle multiple databases and integrate them with each other. He also needs to know how to ensure data security when managing databases. Relational databases that he should be familiar with are, for example, MySQL, PostgreSQL, MariaDB or MongoDB.
Asynchronous programming allows for the non-linear execution of tasks. This means that the next task does not have to wait for the previous one to finish to be started. Node.js is based on the ability to perform two functions simultaneously, which significantly increases performance. The developer must be able to write code asynchronously to take advantage of this feature of the environment.
The code should be written in such a way that not only ensures fast operation of the application, but is also understandable to other team members. The key here is object-oriented code, i.e. dividing it into smaller elements. This makes it much easier to read by other developers.
