Node.js is the ultimate form of a notably scalable and customizable tech. Node.js is an cross-platform, back-end, open-source, JavaScript runtime environment, functioning on Chrome’s V8 that executes JavaScript code outside a web browser and lets you effortlessly develop fast and scalable web applications. This engine takes the code of your JavaScript and convert it into a faster machine code. Machine code refers to low-level code that can be run by computers without needing to first interpret it.
JavaScript and Node.js, are the codes that operate much faster in server-to-client direction. This takes the performance ability of the web applications to another level. A steady and secure non-blocking I/O model, simplifying the code beautifully is ensured by the website application development of Node.js. Developers can write command line tools with JavaScript using Node.js and for server-side scripting, which means running scripts server-side to produce content for dynamic web page before the page is sent to the user's web browser. Node.js platform uses a “single-threaded event loop” unifying web-application development around a single programming language, rather than different languages for server-side and client-side scripts. A "JavaScript everywhere" paradigm is also represented by Node.js.
Node.js was introduced for common use when the original developers of JavaScript altered its format from something that could only run in the browser to something that could run on your machine as a standalone application. Now JavaScript can be used to do much more than just making websites interactive. JavaScript is now equipped with the capability to do things that is done by other scripting languages like Python.
MongoDB refers to an open source NoSQL database management program, that is utilized as an alternative to traditional relational databases. NoSQL databases are highly beneficial when working with large sets of distributed data. MongoDB is a tool that manages document-oriented information with storing and retrieving information. Various forms of data are supported by Mongo DB.
This particular banner is to be used in all the “big data applications” and other processing jobs involving data which doesn't fit well in a rigid relational model. MongoDB architecture is made up of collections and documents, instead of tables and rows that are used in relational databases. In companies, Mongo DB is applied for its ad-hoc queries, indexing, load balancing, server-side JavaScript execution, aggression and other features.
MongoDB utilizes records that are made up of documents, containing a data structure and constituting field and value pairs. Documents forms the basic unit of data in MongoDB, these documents are somewhat similar to JavaScript Object Notation, but it uses a variant called Binary JSON (BSON). Using BSON is beneficial as it could accommodate more data types. These documents also incorporate a primary key which is used as a unique identifier and the fields of these documents are similar to the columns in a relational database.
The sets of documents referred to as collections functions as the equivalent of relational database tables. Several different types of data constitute collections, but it cannot be spread across different databases. The mongo shell is one of the standard components of the open-source distributions of MongoDB. Once MongoDB is installed, mongo shell is connected to their running MongoDB instances.
Android is a “widely-adopted, open-source operating system” based on a modified version of the Linux kernel designed primarily for touchscreen mobile devices such as smartphones and tablets. A unified approach is provided to the application development team with Android, as they need to develop the app only for Android, and it will run on all the devices powered by Android. The source code of Android is known as “Android Open-Source Project,” which is primarily licensed under the “Apache License.” It is developed by a consortium of developers known as the “Open Handset Alliance” and Google is the commercial sponsor of the operating system.
A portion of the android platform is given for free to hardware manufacturers and phone carriers who want to use Android on their devices. The manufacturers are charged by Google only if they also install the Google apps. All the major devices that is used by Android also opt for the Google apps portion of the service. It is the software that constantly runs on the phone, managing all the basic functions and supporting all the apps that are run on top of it.
In November 2007 Android was introduced for the very first time, with the first commercial Android device, the HTC Dream, that was released in September 2008. Android has been the best-selling OS worldwide on smartphones since 2011 and on tablets since 2013 with around 32.9 million phones being sold with Android operating system in 2011. The worldwide market share of Android is 75%, making them the biggest competitors for iOS. It is the largest installed base of any operating system as of May 2021, with over three billion monthly active users,. Android 11 is the currently stable version of Android and it was released on September 8, 2020.
This mobile operating system was developed by Apple, exclusively for its hardware. It is formerly known as iPhone 0S. This operating system powers several mobile devices of the company, including iPhone, iPod Touch and iPads. It is the second-most widely installed mobile operating system, after Android across the globe. iOS forms the basis for three other operating systems made by Apple: larger screen-friendly version of iOS, named iPadOS, tvOS, and watchOS. It is a proprietary software, with some parts of it being open source under the Apple Public Source License and other licenses. All the models of iPhones can be operated in iOS and its primary rival is Google’s Android.
In 2007, iOS was launched with the first-generation iPhone, from then on it had supported various other Apple devices such as the iPod Touch and the iPad. The app store of Apple contains more than 2.1 million iOS applications, 1 million of which are native for iPad. Several versions of iOS are being released annually. The current stable version, iOS 14, was introduced to the public on September 16, 2020, with several user interface changes, including the ability to place widgets on the home screen, a compact UI for both Siri and phone calls, and the ability to alter both the default web browser and email apps.
Hybrid applications refers to the software’s installed on a device, just like any other app. They possess elements from both native apps, applications developed for a specific platform such as iOS or Android, and elements from web apps, websites that act like apps but are accessed on the Internet via a browser but are not installed like any other app. The core of a hybrid app is written with the same technology that are used for websites (HTML, CSS, and JavaScript) and mobile web implementations, which are then encapsulated within a native application on a mobile device. Hybrid apps are essentially web apps that have been put in the shell of native app.
When being used, these apps display web pages from a desktop website that are adapted to a WebView display. The content related to website and web pages can either be displayed as soon as the app is opened or for only certain parts of the app. Implementation of an abstraction layer tends to be a real secret behind hybrid apps exposing the functionalities of the device to the hybrid app as a JavaScript API. The security boundary between the browser and the device APIs doesn’t allow it with Mobile Web implementations.
Hybrid apps are popular because the developers only need to write code for a mobile app once and accommodate multiple platforms. The functioning of hybrid apps is comparatively slower than website or native versions of the same app because they add an extra layer between the target platform and the source code.
PHP is a widely-used, open-source, general-purpose, server-side scripting language used to develop static, dynamic websites or web applications. It can be embedded into HTML and is especially suited for web development. Hypertext Pre-processor is the full form of PHP, and earlier it was known as Personal Home Pages. The server with PHP installed can only read PHP scripts. The client computers where PHP scripts are to be assessed require a web browser only. It started out as a small open-source project and developed later as more and more people found out how useful it was.
The first version of PHP was unleashed way back in 1994 by Danish-Canadian programmer Rasmus Lerdorf. Any type of data, such as generated HTML or binary image data, can be the result of interpreted and executed PHP code on a web browser or it might be obtained as HTTP response.
The generation of this response can be facilitated by several existing web content management systems, web template systems and web frameworks. Various programming tasks not related to the web context, such as robotic drone control and standalone graphical applications can also be performed using PHP. The command line can directly execute PHP code. Dynamic content, databases, and session tracking can be created by PHP, it can even build entire e-commerce sites. A number of popular databases can be used to integrate PHP.
PHP performs system functions, it can create, open, read, write, and close files from a system. It can obtain data from saved files, save data to a file, through email you can send data, return data to the user. Elements can be added, deleted, or modified within your database through PHP.
Laravel is an open-source PHP framework for web application with expressive, and elegant syntax, which is robust and easy to understand. This particular framework eases the entire development process and makes the common tasks used in a wide range of web projects, such as routing, authentication, sessions, and caching pain free. The Laravel developers have a notion that development must be fun, and creative experience to be truly fulfilling. This particular software makes the entire process of development a pleasing one for the developers without sacrificing the functionality of the application as happy developers make the best code.
The Lavarel developers have also made an attempt to combine the very best of what we have seen in other web frameworks, and offer a rich set of functionalities incorporating the basic features such as implementing the framework in other languages, such as Ruby on Rails, ASP.NET MVC, and Sinatra.
The access to Lavarel is comparatively easy, yet it is a powerful tool required for large, and robust applications. A superb inversion of control container, expressive migration system, and tightly integrated unit testing support avails you the tools to build any application with which you can perform the tasks. A model-view-controller design pattern is followed by Lavarel. The existing components of different frameworks is reused by Lavarel, which helps in creating a web application. Hence it designs a much more structured and pragmatic web application. The rich set of features of Lavarel will boost the speed of web development and saves a lot time if you are planning to develop a website from scratch. A website built in Laravel is safe and prevents several web attacks.
MySQL is among the extensively recognized technologies in advanced big data world around the globe. It is referred to as the most popular database, which is currently enjoying widespread, and effective use regardless of industry. Hence, it is clear that anyone involved with enterprise data or general IT should at least aim to have a basic familiarity with MySQL.
With MySQL, fast, powerful, and secure data storage systems can be immediately built even by those who are new to relational systems. All the major syntax and interfaces of Mysql forms the perfect gateways towards the wide world of other popular structured data stores and query languages. It is a relational database management system (RDBMS) developed by Oracle and is based on structured query language (SQL).A relational database in particular, is a digital store that collects data and further organizes it according to the relational model. An RDBMS is basically a set of software tools employed to actually implement, manage, and query such a database.
MySql is integrated by various software stacks in order to build and maintain everything from customer encountering web applications to powerful, data-driven B2B services. Its stability, pen-source and rich feature set, paired with ongoing development and support from Oracle, have meant that internet-critical organizations such as Facebook, Flickr, Twitter, Wikipedia, and YouTube all employ MySQL backends.
React Native is a prominent mobile app framework that can rule on everyone. It has been used by hundreds of business units across the globe, including Microsoft, Uber and Facebook, and across a whole range of industries. It is based on JavaScript that provides the developers with a platform to build native mobile apps for both iOS and Android. Through this framework application can be created for several platforms using the same codebase. React Native was developed for the first time by Facebook as an open-source project in 2015. Within a couple of years, it came out to be one of the top mobile development solutions. It empowers some of the leading mobile apps of the world, including Facebook, Instagram and Skype.
There are several reasons behind the global success of React Native. The first reason is by employing React Native, code needs to be created only once by the company and further it is used to empower both their iOS and Android apps. It minimizes the expenditure of time and resources. Then, the development of this framework was based on React – a JavaScript library, which was already immensely popular by when the mobile framework was developed. But it would be interesting to note the similarity of it to many other revolutionary inventions, it was developed as a response to a big technological mistake.
React.js is the worldwide renowned front-end JavaScript library in the field of website applications. React, React.js or Reactjs are different ways in which React.js are represented. It is employed by both established companies and newly-minted startups. React delivers many advantages to the table, making it the utmost preference.
React is an open-source, component-based, front-end JavaScript library created for building fast and interactive user interfaces and handling the application’s view layer for web and mobile apps. React was developed by a software engineer, Jordan Walke who is working for Facebook. React provides the developers with a platform to build large web applications where data can be changed, without reloading the page. Fast, scalable, and simple features of React are also used to create reusable UI components. It can also be combined with several other JavaScript libraries or frameworks, such as Angular JS in MVC.
Features of React
JSXReact uses JSX instead of using regular JavaScript for templating. In the React framework HTML syntax is processed into JavaScript calls, hence allowing us to write in pure old JavaScript.
Virtual Document Object ModelThe in-memory data structure cache of React which constitutes all the changes made and also update the browser is Virtual DOM.
Single-Way data flowIn React, a set of immutable values are transferred to the component’s renderer as properties in its HTML tags. Several elements of VDOM can’t directly modify any properties but can only transfer a call back function which we can be used to do alterations.
Java is a class-based and general-purpose programming language and computing platform for application development, developed by James Gosling of Sun Microsystems in 1991. It is designed to minimize the implementation dependencies. Various applications and websites don’t work unless you have got Java installed. This fast language with secure and trustable features are widely used in order to develop Java applications everywhere from laptops to game consoles to data centres to cellphones to scientific supercomputers to the Internet.
Java is a widely used software platform running on billions of devices, including mobile devices, notebook computers, medical devices, gaming consoles and many others. All the rules and syntax of Java are based on the C and C++ languages. Developing software with Java avails you a major advantage of portability, on writing a code for a Java program on a notebook computer, you can easily move the code to a mobile device. This language was developed with the chief objective to be able to write once, run anywhere. This language was developed with the primary objective to be able to "write once, run anywhere.
You must understand that Java is much different from JavaScript as Javascript does not need compilation, while Java code need to be compiled. Also, Javascript runs only on website browsers while Java can run everywhere. Though new and improved software development tools are introduced to the market at a remarkable pace, displacing incumbent products. Even during this continual turnover, Java’s longevity is very impressive; as even after more than two decades of its creation, Java still stands as the prominent language for application software development. It is selected by developers over all other programming languages including Python, Ruby, PHP, Swift, C++, and others, making Java an important requirement for competing in the job market.
