What is the difference between PM2 Cluster vs Fork Mode in Node.JS

The main difference between fork_mode and cluster_mode is that it orders pm2 to use either the child_process.fork api or the cluster api.

Fork mode

Take the fork mode as a basic process spawning. This allows to change the exec_interpreter, so that you can run a php or a python server with pm2. Yes, the exec_interpreter is the “command” used to start the child process. By default, pm2 will use node so that pm2 start server.js will do something like:

require('child_process').spawn('node', ['server.js'])

This mode is very useful because it enables a lot of possibilities. For example, you could launch multiple servers on pre-established ports which will then be load-balanced by HAProxy or Nginx.

Cluster mode

The cluster will only work with node as it’s exec_interpreter because it will access to the nodejs cluster module (eg: isMaster, fork methods etc.). This is great for zero-configuration process management because the process will automatically be forked in multiple instances.

For example pm2 start -i 4 server.js will launch 4 instances of server.js and let the cluster module handle load balancing.

Why use Node.js for Web Development? Benefits and Examples of Apps

Front-end web development has been overwhelmed by JavaScript highlights for quite a long time. Google, Facebook, Wikipedia, and most of all online pages use JS for customer side activities. As of late, it additionally made a shift to cross-platform mobile development as a main technology in React Native, Nativescript, Apache Cordova, and other crossover devices. 

Throughout the most recent couple of years, Node.js moved to backend development as well. Designers need to utilize a similar tech stack for the whole web project without learning another language for server-side development. Node.js is a device that adjusts JS usefulness and syntax to the backend. 

What is Node.js? 

Node.js isn’t a language, or library, or system. It’s a runtime situation: commonly JavaScript needs a program to work, however Node.js makes appropriate settings for JS to run outside of the program. It’s based on a JavaScript V8 motor that can run in Chrome, different programs, or independently. 

The extent of V8 is to change JS program situated code into machine code — so JS turns into a broadly useful language and can be perceived by servers. This is one of the advantages of utilizing Node.js in web application development: it expands the usefulness of JavaScript, permitting designers to coordinate the language with APIs, different languages, and outside libraries.

What Are the Advantages of Node.js Web Application Development? 

Of late, organizations have been effectively changing from their backend tech stacks to Node.js. LinkedIn picked Node.js over Ruby on Rails since it took care of expanding responsibility better and decreased the quantity of servers by multiple times. PayPal and Netflix did something comparative, just they had a goal to change their design to microservices. We should investigate the motivations to pick Node.JS for web application development and when we are planning to hire node js developers. 

Amazing Tech Stack for Web Development 

The principal thing that makes Node.js a go-to environment for web development is its JavaScript legacy. It’s the most well known language right now with a great many free devices and a functioning local area. Node.js, because of its association with JS, immediately rose in ubiquity — presently it has in excess of 368 million downloads and a great many free tools in the bundle module. 

Alongside prevalence, Node.js additionally acquired the fundamental JS benefits: 

• quick execution and information preparing; 
• exceptionally reusable code; 
• the code is not difficult to learn, compose, read, and keep up; 
• tremendous asset library, a huge number of free aides, and a functioning local area. 

In addition, it’s a piece of a well known MEAN tech stack (the blend of MongoDB, Express.js, Angular, and Node.js — four tools that handle all vital parts of web application development). 

Designers Can Utilize JavaScript for the Whole Undertaking 

This is perhaps the most clear advantage of Node.js web application development. JavaScript is an unquestionable requirement for web development. Regardless of whether you construct a multi-page or single-page application, you need to know JS well. On the off chance that you are now OK with JavaScript, learning Node.js won’t be an issue. Grammar, fundamental usefulness, primary standards — every one of these things are comparable. 

In the event that you have JS designers in your group, it will be simpler for them to learn JS-based Node than a totally new dialect. What’s more, the front-end and back-end codebase will be basically the same, simple to peruse, and keep up — in light of the fact that they are both JS-based. 

A Quick Environment for Microservice Development 

There’s another motivation behind why Node.js got famous so rapidly. The environment suits well the idea of microservice development (spilling stone monument usefulness into handfuls or many more modest administrations). 

Microservices need to speak with one another rapidly — and Node.js is probably the quickest device in information handling. Among the fundamental Node.js benefits for programming development are its non-obstructing algorithms.

Node.js measures a few demands all at once without trusting that the first will be concluded. Many microservices can send messages to one another, and they will be gotten and addressed all the while. 

Versatile Web Application Development 

Node.js was worked in view of adaptability — its name really says it. The environment permits numerous hubs to run all the while and speak with one another. Here’s the reason Node.js adaptability is better than other web backend development arrangements. 

Node.js has a module that is liable for load adjusting for each running CPU center. This is one of numerous Node.js module benefits: you can run various hubs all at once, and the environment will naturally adjust the responsibility. 

Node.js permits even apportioning: you can part your application into various situations. You show various forms of the application to different clients, in light of their age, interests, area, language, and so on. This builds personalization and diminishes responsibility. Hub accomplishes this with kid measures — tasks that rapidly speak with one another and share a similar root. 

What’s more, Node’s non-hindering solicitation handling framework adds to fast, letting applications measure a great many solicitations. 

Control Stream Highlights

Numerous designers consider nonconcurrent to be one of the two impediments and benefits of Node.js web application development. In Node, at whatever point the capacity is executed, the code consequently sends a callback. As the quantity of capacities develops, so does the number of callbacks — and you end up in a circumstance known as the callback damnation. 

In any case, Node.js offers an exit plan. You can utilize systems that will plan capacities and sort through callbacks. Systems will associate comparable capacities consequently — so you can track down an essential component via search or in an envelope. At that point, there’s no compelling reason to look through callbacks.

 

Final Words

So, these are some of the top benefits of Nodejs in web application development. This is how Nodejs is contributing a lot to the field of web application development. 

I hope now you are totally aware of the whole process of how Nodejs is really important for your web project. If you are looking to hire a node js development company in India then I would suggest that you take a little consultancy too whenever you call. 

Good Luck!

Node Js Vs. React Js: Difference Between Node JS and React JS

The Js at the end of both Node and React refer to the language of JavaScript. Node and React are both the frameworks of  JavaScript. However, the ensuing language that both the frameworks have been the same, the use cases for both of these frameworks. However, they are totally different.

Some people might even argue that to find the difference between node js and react js is just like comparing a train to an airplane. Both of them work on an entirely different domain. The main reason why Node and React’s comparison is unfair is that Node.js is a framework to handle back-end, meaning it is developed to handle the server-side computations.

Meanwhile, React.js was developed to handle the User Interface and User Experience (UI/UX). Although glaringly present, the differences do not take anything away from the sheer power and the versatility that each of these frameworks brings into their respective domain. Another way to string together the main difference would be that neither Node.js or React.js are interchangeable at any stage of your web development project.

With that being said, there are individual minute differences that any developer should consider when working on their projects, such as the performance, the learning curve, the community of both the frameworks and microservices’ support. Listed below, you will find a comprehensive weighted comparison of node js vs. react js on the aforementioned grounds. But before we begin our comparison, we must first understand both Node.js and React.js intricately and discuss the various use cases of these technologies.

Node.js

What exactly is the Node.js JavaScript framework?

The need for a robust means to handle the backend, server-side development yielded the framework we know as Node.js. Node.js was developed by Google and is based out of their V8 engine present in their web browser, i.e., Google Chrome. Node.js is a lightweight framework mainly because of its event-driven nature and the fact that it does not block the I/O. Node.js really shines the brightest when used to host API’s, access the database for the website, and serve the HyperText Transfer Protocol.

Who are the people making use of Node.js?

Node.js enjoys a very diverse clientele, with major players like Netflix, Uber, and Trello, all making use of Node.js in their backend. The reason why each of these companies uses this framework is different. Netflix, the leading online content streaming service, has to conduct A/B testing; only then would they serve the 93 million active users of their streaming service. The lightweight nature of Node.js has allowed them to serve the content swiftly. They have both reduced their startup time by over 70% and improved their scalability by shifting to Node.js.

Angular.JS vs Node.JS || Find the best for your project - Valuecoders

Whether MNCs or Startups, many companies use Angular.JS or Node.JS to develop web applications as these are among the best JavaScript frameworks used for web applications.

According to Statista, Node.JS and Angular.JS are the best frameworks used by developers, with 51.4% and 25.1%, respectively.

Both these frameworks have unique features and advantages, which makes them preferred over the other frameworks.

Many enterprises use these frameworks without even understanding their uniqueness and the type of projects they are suited or made, which is why, today, I will compare some of the best features and advantages of these two frameworks.

So, let’s dive into and learn various things about Angular.JS vs Node.JS without any further delay.

Angular.JS

AngularJS is a fundamental framework for robust web apps. It makes you use HTML as your template language and allows you to spread HTML’s syntax to clearly and succinctly express your application’s components.

AngularJS’s dependency injection & data binding eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it a perfect partner with any server technology.

AngularJS is what HTML would have been having it been designed for applications. HTML is a great declarative language for static documents. It does not contain much in creating applications.

Let’s discuss some main features of Angular.JS and its advantages:

Data Binding

Data binding is probably the most impressive and helpful feature of AngularJS. It will save you from writing a considerable amount of repetitive code.

A typical web application can contain up to 80% of its codebase, dedicated to traversing, manipulating, and listening to the DOM. Data binding makes this code escape so you can concentrate more on your application. Think of your Model as the only source of truth for your application. Your model is where you go to read or update anything in your application.

Data binding directives provide a projection of your Model to the application’s view. This projection is perfect and occurs without any effort on your part.

HTML UI

Another great feature of AngularJS is the fact that it uses the HTML language to build UI. The HTML language is a general and declarative language with concise tags that are easy to understand.

This leads to a more systematic and straightforward UI. JavaScript interfaces are usually more challenging to organize and develop. If you’re looking for a solution that’s fast, easy, and simple to use at a moment’s notice, then this could be it.

Model View Controller (MVC)

MVC is a software design pattern for developing web applications. It is made up of:

Directives allow angular to provide additional functionality with the HTML language. Directives can also be used to “decorate” components with behavior and manipulate DOM attributes in interesting ways. The controller does not need to control the DOM directly, as this must be done through directives.

Directives are a separate part of the set of elements that can be used anywhere other than a web application. The directives provide developers with the element-rich HTML they need to strengthen their online presence.

If you are looking to hire a dedicated angular developer, you can hire an angular js development company.

Node.js is a free and open-source server environment that runs on various platforms(Windows, Linux, Unix, Mac, OS X, etc.). Node.js uses JavaScript on the server.

Node.js is preferred because of its rich library of several JavaScript modules that helps in simplifying web development to a greater extent. Many companies hire Node.js developers for making a NodeJS web application development as it possesses many features.
