But what is Node.JS?
Finally, we have web applications with real-time bidirectional connections in which both the server and the client can initiate communication, unlike the traditional paradigm where only the client starts sending data. This makes Node.JS very suitable for the construction of Real-Time Applications (RTA). This fact has also been confirmed by most of the developers working in the overseas and software development companies.
What are Real-Time Applications (RTA)?
An RTA is a program that works within a period of time that the user perceives as immediate or current. The latency must be less than a value predefined by the developer or the user, usually measured in seconds. The use of RTA in other applications is called Real-Time Computing.
Some examples of RTA are:
- Video conferencing applications
- VoIP calls
- Online games or network game applications
- Instant messaging (IM) apps like WhatsApp or Telegram.
- Some e-commerce transactions, such as securities brokerage
- Other chat applications
- Community storage systems that require continuous updating of the data
However, there is still a big question:
What are the reasons why Node.JS is the most popular option in building RTA?
Let’s explore them:
- Share and reuse: if you have any problems, the Node Package Manager (NPM), with its repository of more than 50,000 packages, can help you find a solution. It is the ideal place for you to upload your codes and help other members of the community.
- Transmissions in Node.JS: Since Node is event-driven, limited I/O tasks are extremely fast and efficient. Streams are UNIX pipes that facilitate the reading of the data sent and channel it to its destination.
- Different modules: it is very important to be able to guarantee the availability of file system I/O, binary network data, data flow, and other functions. Node.JS modules use an API designed to simplify the writing of server applications.
- High performance: thanks to Node.JS, PayPal has been able to double the number of requests per second and reduce the response time by 35%. Another company benefited from using Node.JS was LinkedIn, the main social network of the planet, which moved its servers from Ruby to Node.JS, managing to reduce the number of servers from 30 to 3 and increase the speed up to 20 times.
Without a doubt, there are very solid reasons that justify the rise of Node.JS. It is one of the best options available today for web development, and still has ample room for improvement. Undoubtedly, it is very likely that this trend continues to gain ground at the expense of more obsolete alternatives, so we recommend everyone to adapt to the new times.
