Uses Of Node.js
Opening a file on the server and returning its content on a client is the most common task for a web server. Node.js handles this task by requesting a file from a server by doing the following steps:
- It sends the task to the system’s file folder.
- It gets ready to handle the next request.
- The file system when gets opened and read the file, the server sends the content to the client.
Node.js is popular because it eliminates the waiting when a request is sent and simply continues with the next request.
Node.js runs single-threaded, asynchronously programming and non-blocking. Node.Js is quite a memory efficient.
In this Uses of Node.js article, we shall focus on the top 10 Uses of Node.JS
Top 10 Uses Of Node.js
What is that Node.js does?
- Node.js generates dynamic page content on the fly.
- Node.js creates, opens, reads, writes, deletes, and closes files on the server machine.
- Node.js collects form data as well.
- Node.js adds, deletes, modifies data in the databases.
The popular Uses of Node.js are as below: –
- Browser Games: – Browser-based games are probably the most exciting application of real-time web. No longer users need to open up a Flash, Java, or other programs such as Shockwave applet to play games. They do it right in their browsers. Node.js used in conjunction with Socket.io and HTML 5, rich and impressive real-time browser games can be designed. Other games such as multiplayer games as well can be created using the same technology.
- Chat Rooms: –These days it is true that most people use phone-based apps or social media platforms to chat with friends. uses of Node.js can create chat rooms very easily. Independent chat rooms probably not very popular on today’s Internet, but this is used a lot in online games which makes more fun when there is a chat component to them.
- Collecting Data: -Massive amounts of data can be collected and made more efficient with the uses of Node.js. large quantities of data into a database usually create a bottleneck, because database access is a blocked operation. Node.js, on the other hand, receive this data, then send it to the backend in a piecewise manner. This ensures that data gets stored without breaking any system.
- Streaming: –Video and audio media content files are uploaded to streaming video such as YouTube or Facebook and the same has to be processed to make it available for viewing or heard by users across the world. The processing of these files happens after they have been uploaded. Using applications of Node.js, these videos can be processed as they are being uploaded. This saves a lot of time and makes media widely accessible at fast speed. Other than video and audio, other data types such as input and output in real time also require real-time processing to work on projects with colleagues spread halfway around the world.
- Real-time applications: – Uses of Node.js is a great choice for those kinds of applications which process a high volume of short messages and require low latency. Such systems can be easily developed with Node.js. Uses of Node.js can also be a good choice for real-time collaborative drawing and editing-type apps. Example: – Trello, DropBox.
- Fast and scalable applications: – Ruby on Rails probably is not sufficient in speed, if there are a ton of requests. uses of Node.js proves to be useful in such situations when faster and a more scalable program is needed. Node has the ability to process many requests, that too at low response times, and it shares things such as validation code between client machine and server. This makes applications of Node.js a great fit for modern web applications. carrying out lots of processing on the client’s side is possible with node.js. Node.js is a popular choice for single-page application sites and mobile apps, where rendering is done on the client’s side, and a JSON API is provided by a backend.
- Processing:- Node.js also very useful, when high volumes of IO-bound requests are to be processed. If a lot of CPU processing requests are required to serve the request, it will not be efficient. if it’s primarily and considers only shuffling data around, then node.js will be quite efficient. A single instance serves a lot more requests that too with the same hardware. Node.js compared to the usual big and thick application is better such as rails.
- API on top of an object DB: – Although Node.js really shines with real-time applications, it’s quite a natural fit for exposing the data from object DBs (e.g. MongoDB). JSON stored data allow Node.js to function even when there is no impedance mismatch and there is data conversion.
- Queued input: – If a huge amount of simultaneous data is received, a database does become a bottleneck as explained above. But, applications of Node.js can handle the database concurrent connections. The system maintains its responsiveness even under a heavy load and that is particularly useful
