Introduction to Node.js Streams

In modern times business owners want to make use of web based applications that can be utilized for performing business activities, make transactions and store information’s of the customers that can be used for data analysis purposes. The major challenge of web based applications is that if suddenly high traffic came to site then server might crash or might not handle too many http requests. To overcome this challenge we make use of NodeJS which is a JavaScript runtime environment that is built on chrome's V8 engine. In this article we will explore the node.js stream, its types, and what are benefits of using NodeJS streams in NodeJS applications.

What Are Node.js Streams?

Nodejs stream allows us to read and write data in a continuous and sequential manner. Nodejs streams allow us to open the file, read the file, and write the file as per unique programming needs. Stream is like an object that let you process the data bit by bit without having to load the entire data in one go. This helps a lot in improving the user experience where the page needs to render while scrolling.

Types of Node.js Streams

There are several ways of using Nodejs streams. Some of them are summarized as given bellow:-

·         Readable Streams: When we want the application to read the data from the source we use readable NodeJS streams. The common method used for reading is .read () and we often use them for events like 'data', 'end' and 'error' to customize the NodeJS application as per unique business requirement.

·         Writable Streams: When the file needs to be stored to specific destination, or some contents of the file need to be changed we can make use of writable stream functions like .write () and use them with events like drain or finish.

·         Duplex Streams: Duplex stream is both readable and writable and cab is used for reading as well as writing simultaneously like TCP socket.

·         Transform Streams: Transform stream is a modified version of duplex stream which is capable of transforming the data as per case for reading or writing. Example of transform stream is compression stream that compresses the data and transform the data size or reduces its file size.

How Do Streams Work?

Just like any other stream NodeJS stream also operates in two modes namely flowing and paused. If the streaming videos are using flowing then the videos can be viewed without any interruptions. However if it is paused then it stops with that frame. We use different methods like .pause (), .resume (), and .pipe (). That can be switched between these models.

Key factors to consider while using NodeJS streams

Nodejs streams can be used for variety of purposes like video streaming, live music streaming, live music concert, streaming applications. The major challenges of such streaming application are using the appropriate protocol. If we use simple file transfer protocol then it will take time and lagging might occur. Hence using appropriate protocol is necessary while using NodeJS streams. Secondly file access errors must be handling appropriately. If the file consist of virus programs and we allow the application to read such file then our application might get infected and data might become inaccessible. While using the NodeJS stream, functions we should take care of their type case, ensure that they are declared without any spelling mistake otherwise they might not work as expected.

How to find best NodeJS development company Portland?

Portland is a place we can find many IT companies. If we are searching for NodeJS Development Company in Portland then we need to consider few things in mind. Before o[opting in for NodeJS development services we must check the experience of the NodeJS development company, whether or not they have dedicated team of expert NodeJS developers or NodeJS programmers who work in collaboration with each other to build highly scalable and efficient NodeJS applications that can be customized for addressing unique business needs.

Nodejs consultants can formulates cost effective plans and strategies for developing highly scalable, robust and secure NodeJS applications for businesses. These applications can handle multiple HTTP requests. Nodejs streams can be used for improving the user experience of the online visitors. These streams can collect data from the user like browsing history and display recommendations of their interests dynamically through web based applications.

To sum up we can say that Nodejs streams play important role in real time application with live streaming features. This helps us to transfer the files quickly and read or write the file with appropriate Nodejs stream functions. Nodejs developers’ expertise of handling NodeJS stream functions and make the application more user friendly with proper implementation.
