Node js development process in Layman terms

---

Every week a programming language with rapid advancements in computer science come in to existence, some become popular and others get extinct. It’s getting tougher to decide what to use in a project and what to leave. In this emerging chaos all of us might have somewhere heard or read about node js but most of don’t have idea that what is it and why it is getting popular. This article targets to introduce audience from all professions with node js.

Technically Node js is an open source JavaScript runtime environment that runs the JavaScript code outside the browser. Open source means it is being built by a community which makes it free to use and runtime environment meant that you can run the code even if it has bugs which can be resolved on the go. The Node js is based on chrome’s V8 JavaScript engine, node wrapper contains a bunch of features that are combined with V8 JavaScript engine. Node wrapper and chrome’s V8 JavaScript engine both are written in C language which makes it faster than its peers.

How Node js works which makes it faster?

The same JavaScript code can be used on both client side as well as server side, this will evict the problem of overwhelming terminals. Node js works like apache tomcat and other servers but on different principles at fundamental level. Conventionally a user terminal sends a request to server and the user terminal waits for server to read that request and waits until it serves the request whereas node js keeps on sending requests to server without waiting for a request to be served first. All the above factors and C language empowers node js to serve requests 10x faster than java and makes it suitable for real time applications.

Why big brands are adopting Node js even when it can’t leverage multiple cores?

Java’s approach to leverage hardware capabilities by simultaneously accessing all cores can help a system to serve more user and requests but the requests won’t be served as fast as we need in real time applications. Node js at the moment works as a single threaded asynchronous micro service which cannot access multiple cores simultaneously but it serves requests really fast as a result the hardware requirements are reduced. For example if YouTube places servers in a country where high speed internet is not accessible to users then serving the requests faster will be a better approach rather than using java to enable the system for rendering 4k content because nobody will be able to watch it.

How big brands like YouTube, Netflix are going to serve requests that need large computing power?

Big brands are changing their large code components with hierarchically attached micro service code components. The approach to switch from macro to node js micro level on JavaScript runtime environment will provide the following benefits:-

• Hierarchically connected micro components can be assigned to work on different cores in such a fashion that the application harnesses the power of multicore functionality.
• 
  
• If a micro level component fails it will not impact the overall functionality of application unless it is one of the most critical micro components.
• 
  
• The faulty component can be fixed even when the application is working.
• 
  
• So applications will not have any downtime.
• 
  
• Faster serving of requests on all hierarchical levels will increase the overall speed of application exponentially.
• 
  
• By serving way more number of requests per unit time will reduce the requirements of hardware.
• 
  
• Companies can observe 10 to 50 percent decrease in hardware requirements.

Where to use Node js?

Node js is being used in backend web applications where stagnant real time access of data is required like banking, finance, trading, combat & defence systems. Now companies are working together to switch from architecture of macro level components to micro level components for inhering the speed from node js at every hierarchical level it will simultaneously increase the fault tolerance of overall system.

Which type of applications can get the most out of Node js?

The applications which depends on real time data and fast loading of data should use node js for back end development of their applications.

• IoT products
• Capital markets digital platform
• Financial services
• Banking
• Video streaming apps
• Ecommerce platforms
• BPM tools
• Project management tools
• Ride hailing services

If you own any web application for above listed products and services then you should reach out a java development company or a web application development company to leverage the high speed back end capabilities with node js development.
