● Accurate speed and performance is a desire of many real-time projects. Node.js is actually a fast; there is no myth in this statement.
● Enormous tools are available at free of cost to apply it in your work.
● The code can be shared and reused when there is a requirement.
Let’s move back and shed some light on its history:
Is Node.js a JS framework?
No doubt it allows you to develop platform independently but not in favour to create a JS framework.
How does it work?
When you disclose the upper covering of Node.js, what you’ll realize under it? Kingdom of event-loop. The web serving techniques figure out a variable thread for an individual call or request. As a result, Random access memory (RAM) is stepped into the condition where it has to handle the excess load. Therefore, Node.js web development, the non-blocking I/O representation only desires a single call or request to respond various concurrent demands in a whole event loop but the condition is without creating an obstacle for RAM.
Merely place data and it will transmit without the involvement of why, when and how type questions. An event loop ensures all asynchronous tasks are accomplished with speed and high level of responsiveness.
Next study what are the features of Node.js?
Here is a list of few appreciable features that make Node.js is the first choice of software architects.
Here Asynchronous means non-blocking, under Node.js library, all APIs are asynchronous. Based on this feature, the server never stands to get the return data from API. It keeps moving to another API and Node.js notification mechanism supports the server with a respond of a previous API call.
It is applied under the MIT license, which was initially released on May 27, 2009; 10 years ago and stable release was done on 12.2.0 / May 7, 2019; 36 days ago.
Node.js is not following buffering criteria; in fact, it directly releases the data in blocks.
Node.js has vast usage in different departments. It is accessible by companies, applications and some projects.
Here are a few examples where Node.js should be used.
The chat application is the best example where Node.js is used. It is data intensive, lightweight and traffic lead application that works on different devices. For the tutorial purpose, its simple and reliable source covers almost all paradigms.
There is a simple chat box on a website, where people put their query with an aim to get a solution. Messages are exchanged and even more than one person can use this chat option at one time. There is no hard and fast rule that only a person can chat at a time and next comes in a row. No, not at all.
Talking of server-side, Chats architectures support the messages coming from the client. In the front-end solution, all the shine or highlighted part depends upon the WebSocket. It’s a communication protocol to establish a connection in two ways:
• It establishes real-time communication between two parties – the browser and the server
• Enabling quick message exchange without consuming any extra time
On the client-side, the HTML page is managed by couple of handlers. One, who picks up the messages send by a user and forward to WebSocket and second is who wait for new message to be sent by another user and then send that message to WebSocket.
2. Data streaming
In maximum web platforms, the HTTP requests and responses that come from the different direction are treated as separate functionality but in reality, data is streaming. Here data that comes in a flow can be processed in an online pattern and this concept is analysed in real time encoding which permits audio and videos to be encoded.
Therefore, the encode functioning of audios and videos can be done within a few seconds. The server is no need to wait for long hours for their encoded results.
The videos are divided and collected in proper format and at last, it stored in your cloud. Then, load the file in your desired quality but during this, if your network connection loses, automatically the lower quality video will be downloaded, it goes back up after the network connection is stable at high speed.
Real-time apps really rely on Node.js because:
• It gives quick action or quick synchronizes between server and client
• Handle multiple client requests at a single time
• Allow to share and reuse the Node.js packages which saved library code
Why “consider Node.js for your project”?
A clear idea is more reliable to trust Node.js technology. Here are some advantages that guide us to develop your project in Node.js:
3. Its an open source so you can get a huge benefit from it.
4. Language factor- it allows a team to use the same language at front or back-end. With the same language, the cost will be reduced.
5. Agility – develop a project that consumes no time and running on a successful track.
Further, see how it is helpful to boost up your productivity but before that install it using an adequate installer.
The installation process can be processed further using windows- official installer and OS X – official installer.
1. Installing modules
NPM is a module manager of Node.js and all these are open source so you can use which are available at your point. With this, create a package in which all modules are listed out along with their version.
There are total 210,000 modules feasible during scripting. In most cases, find out the most suitable module is a quite tough task.
2. Text files
Use the modules to process text files. Sometimes, need to gather information from files. Moreover, real-life apps are the more critical case in all this.
3. Processing images
After processing text files, time to divert towards images. Use gm module to automate occurring again task. Need to get GraphicsMagick if you’re using gm module.
4. Creating a web app
To create server-side web apps, Node.js is greatly in use. But it can be employed to create frontend apps too.
The entire article is based on Node.js and its usability in real time. As it’s an open source and is really helpful in almost all spheres. Its accompany you to boost up the production and third party module will work a lot without putting much more efforts on you.
We’ve discussed Node.js in sequence. Firstly its definition, reality; its not a framework, examples where it works and how it works, what are its features and plenty of other concepts. In the end, short but well-explained installation or module parameters. Last but not least, using Node.js, you can build amazing designs.
