Uses of Node.js

Posted by vishnu on November 29th, 2019

Node.js is an open-source JavaScript platform. It is used to execute JavaScript code outside the browser during the runtime environment. Node.js can run on different platforms, be it Windows, Linux, Unix, Mac OS, etc. Opening a file on the server and returning content to a client is the most common task for a Web server. Node.js handles task by requesting a file from a server by doing the following:

  • It sends the task to the system file folder.
  • He is ready to handle the next request.
  • When the file system is opened and reads the file, the server sends the content to the client.

Node.js is popular because it eliminates the wait when a request is sent and simply continues with the next request.

The popular Uses of Node.js are as below: –

  1. Browser Games:Browser-based games are probably the most interesting application of the Web in real-time. Users no longer need to open a Flash program, Java or other programs such as the Shockwave applet to play games. They do it well in their browsers. Node.js used with Socket.io and HTML 5, rich and impressive real-time browser games can be designed.
  2. Chat Rooms:These days, it's true that most users are using phone-based apps or social networking platforms to chat with friends. The uses of Node.js can create chat rooms very easily. Independent chat rooms are probably not very popular on the Internet, but this is used a lot in online games, which is more fun when there is a chat component.
  3.  Data collection: Massive amounts of data can be collected and made more efficient with the use of Node.js. Node.js, on the other hand, receives this data and sends it to the background in a piecewise manner. This ensures that the data is stored without breaking any system.
  4. Streaming: Video and audio content files are uploaded to streaming videos such as YouTube or Facebook and must be processed for viewing or listening by users around the world. These files are processed after they are downloaded. By using Node.js applications, these videos can be processed as they are uploaded. This saves a lot of time and makes the media widely accessible at a fast pace.
  5. Mean Stack: Mean stack makes development simple and easy, from both a developer and device perspective. MEAN can also be integrated with other modules. Example: - Mongoose is used with Node.js, which has greatly facilitated integration with MongoDB.
  6. Real-time applications: Node.js is an excellent choice for applications of this type that handle a high volume of short messages and require low latency. Such systems can be easily developed with Node.js. Example: - Trello, DropBox.
  7. Fast and scalable applications: Node.js is useful in situations where a faster and more scalable program is needed. The node has the ability to handle many requests that too at low response times, and shares items such as the validation code between the client device and the server. This makes Node.js applications perfectly suited for modern web applications.
  8. Processing:Node.js is very useful when large volumes of IO-related queries need to be processed. If many requests for CPU processing are required to meet the demand, this will not be effective. if it’s mainly about shuffling data around, then node.js will be quite efficient.
  9. API on top of an object DB: Although Node.js really stands out with real-time applications, it's quite natural to expose data from object databases (for example, MongoDB). JSON stored data allows Node.js to work even when there is no impedance mismatch and there is data conversion.

  10. Queued input: If a considerable amount of data is received simultaneously, a database becomes a bottleneck, as explained above. But Node.js applications can handle simultaneous connections to the database. The system maintains responsiveness even under a heavy load.
