ReactJs developed by Facebook has become one of the most sought after by SaaS developers for their SaaS applications. Netflix, Facebook, Yahoo! Mail are all those SaaS applications which have assumed greater significance in our life. They have all been made with ReactJs as an effective platform and like always have exceeded user expectations. ReactJs became open-source from 2015 and with its library used for the user interface. Stackoverflow ranked it with the highest demand in 2017.
What is ReactJs? As discussed earlier, ReactJs is an open-source JavaScript library that is used for building user interfaces for single-page applications. ReactJs handles the view layer for both web and mobile-based applications and lets the users create many UI components. ReacrtJs allows the developers to create large web applications wherein the changes in the data could be made without the need to reload the application. React is not just fast but is pretty simplistic and flexible giving ReactJs developers a great reason to use it. Let’s understand its features... React Native It has native libraries that were announced by Facebook in 2015. These native libraries proved to be a boon for native applications like iOS, Android and UPD that delivered them the React architecture. It is mainly used for building a mobile app framework with the help of JavaScript. The same design is applied as React allows the building of applications using the rich UI components. It uses the foundational UI building blocks for all iOS and Android applications. JSX React uses JSX for templates because it is a very a simple JavaScript platform that enables efficient HTML quoting. It also applies the HTML tag syntax to deliver the sub-components. This syntax is furthered into JS calls for the holistic React framework. Single-way data flow In the case of ReactJs, a group of abiding values is transported to the renderer of components as properties in its HTML tags. It is not possible to directly alter any property by the component but it can surely deliver a call back that will help with the modifications. Virtual document Object model ReactJs ecosystem generates an in-memory data structure cache that makes note of changes thereby updating the browser. This leads to the enabling of a special feature that aids ReactJs developers to code. Famous SaaS applications built on ReactJs Facebook employees conceptualized ReactJs which was further developed by them. So, it does not come as a surprise that FB started off with using ReactJs for its newsfeeds. In 2013, Facebook outsourced ReactJs for everyone to use it. Its best pointers have been implemented by FB on its news feed, messenger, ads and much more. The mobile app of Reddit was created using ReactJs. React native is considered the best to apply for mobile application development. Reddit as we all know is a popular discussion forum that has about 250 million active users who give their insights on issues including political issues and humor. Reddit users usually take to their mobile version to discuss in feeds with convenience. The subreddit ReactJs currently boasts of more than 60k followers where people share job offers, tutorials concerning their scope of the study. In 2018, ReactJs was used by Reddit in order to alter its platform. Netflix Netflix is very high on video loads hence it is extremely important for it to have enhanced speed and performance. Netflix has received the advantage of generating faster rendering due to its virtual DOM. It uses ReactJs to improve the holistic experience on all devices from televisions to mobiles. Pinterest is a wonderful SaaS application that is a unique platform for inspirational browsing and photo collection. As of now Pinterest has 200 million active users and is a preferred platform for content sharing. It has widgets follow button, profile widget all built using ReactJs making it one of the most sought after platforms for SaaS applications. DropBox It also is a popular SaaS application to store files and photos online. It was not developed with ReactJs but was later switched to it because of the great SEO features it offers apart from quick rendering, testability, and advantage of a single-flow direction. This SaaS application is dependent on a coherent process to administer and manage hue data that includes photos, videos, and files for many users simultaneously. 4 reasons leading you to ReactJs for SaaS applications Reusability of code ReactJs creates components on single-page applications that eventually function independently. Its structure replicates a building block that has small chunks individually responsible for a particular feature good enough for building a complex system. The components can be further reused for other projects by allowing the SaaS developers to create the base that can be used to build instead of building from the beginning. Complicated tasks are further classified into many other tasks which can be focused upon one by one. Fast Rendering The virtual DOM model enables faster rendering. The virtual DOM is an updated version of the original DOM which leads to superior performance, great SEO and easy maintainability. The tracking of components that need re-rendering also can be easily tracked which is the best part as only targeted components will need it on the client-side. SEO-friendly SaaS applications also need effective Search Engine optimization apart from the other set of features. Google rankings and user experiences should be on the top to let people stay ahead of the competition. Websites and applications which are slower to react result in losing users within a few seconds which proves that coding should be done in a manner so as to make the application SEO friendly for the search engines to catch it. The use of ReactJs for creating single-page applications helps in great performances as there is lesser retrieval of data. The web page and its components function without the need to take a trip back to get more HTML data. This allows for instantaneous responses, especially between two tabs. Hence rather than extracting new data in order to load a full page, HTML data initiated changes with user response. Effortless transfer from web page to mobile app This also can be done smoothly as ReactJs can enable the easy transfer of a single-page application to a mobile app. Conclusion The full potential of ReactJs is being realized with companies and their SaaS applications continuously preferring ReactJs to either build it from scratch or modify the existing version. ReactJs goes down as a lightweight and simple library that is tailored to meet the modern needs of the developers.

A comparison between Node.Js and Java is essential. Java is a class-based object-oriented program which has been popularly denoted as “write once run anywhere” programming language by the developers worldwide. It has proven to be quite portable in the sense that a Java program written for any platform, must run on fortification of both operating systems as well as the hardware. NodeJs application development is a run-time application that is used to generate server-side applications. NodeJs developers use NodeJs to create JavaScript as an open-source and cross-platform application. NodeJs developers prefer it because the scripts are written very fast and are also extremely flexible. Java, on one hand, is a language while NodeJs is a holistic ecosystem that has been made on Js which also syncs with Google’s V8 engine. A Comparison of Performance: NodeJs v/s Java Single vs Multi-threaded The first parameter to compare both NodeJs and Java is whether they are a single thread programming language or multi-thread. NodeJs is single-threaded meaning that only one request can be handled at a time. Only when one database query resolution is completed the second one is taken up. When the database completes the task, the message is posted in the event queue. There is no gap in monitoring the queue as it is done instantaneously. Upon detecting the event, it is removed after which the processing begins. For I/O applications requiring network access, Node Js is a perfect choice. NodeJs development companies will be able to resolve queries of multiple clients without the need to use hardware. One disadvantage is that it might not be the best solution for extreme CPU based applications like Video encoding, image manipulation, etc. Java is Multi-threaded implying that many tasks can be undertaken in one go. Multithreading helps in the better performance of the applications. For complex projects requiring the execution of multiple tasks, Java is recommended. I/O model I/O communication model is nothing but the entire gamut of processes that displays the data. I/O is of two types namely blocking and non-blocking. Blocking means that the thread will not be able to perform fully unless the whole I/O is received while non-blocking means that even when the one I/O request is underway, it can also take up other requests without the need to wait. NodeJs development is non-blocking and asynchronous while Java has a blocking I/O. NodeJs developers can easily send many requests at the same time which is opposite in the case of Java. High concurrency High concurrency is a performance parameter that is needed for enterprise web applications. Java, as we all know, is multi-thread and it needed a dedicated thread for every request. For concurrency, it will need many threads. But, when the load increases, the striking time between multiple threads is a costly affair. With the increase in threads, the operating system becomes extremely busy cutting time, that the CPU is not able to execute its task. On that front NodeJs is extremely efficient. When it is running in full mode, the CPU will be busy but it will still not hamper the OS. Popularity NodeJs v/s JavaBoth are popular but the popularity of NodeJs has exceeded that of Java. The entire ecosystem is transformational and expands the scope of the overall development. A look into the StackOverflow illustration given below, the global usage of NodeJs is path-breaking. Compared to other countries America is the highest adopter of NodeJs development as it considers it one of the most progressive of all ecosystems. Country-wise comparison of NodeJs shows that in terms of adoption, America is the biggest adopter of NodeJs application development. NodeJs is considered the most progressive of all ecosystems. It hasn’t taken a lot of time for NodeJs to step up the charts because it has earned the reputation of being versatile. It is also easy to use and a great way for beginners. Its support in the form of library and resources also is abundant. Java being more than 20 years old is still in demand and is used in many applications. These are the popular apps created on the NodeJs platform. Much as these names are considered trustworthy, NodeJs also is considered a trustworthy solution by NodeJs developers. Java too can be credited with several top names as given in the illustration below: What’s good about NodeJs & Java Application development becomes easier, to begin with, NodeJs follows the agile methodology which is great for an enterprise application development project as scalability is required. NodeJs development also works twice the speed of Java with the usage of fewer resources. NodeJs developers use 33% lesser codes and 45% fewer files. It has a huge pool of libraries and NodeJs developers have established that the infrastructure does not have to be built with scratch. The application development on NodeJs is event-driven. With its non-blocking method, it is light-weight and wonderful for data-intensive enterprise application development. Java also is versatile in the sense that it supports all platforms, devices, and OS. With its in-built security features with Java compiler and Virtual machine, it has carved a trustworthy name for itself. It also uses the Robust code feature that helps the application development take all cases of errors just with code. Java also has a great integration capability and developers deem it fit for client-side technologies as it is a mature language. Wrap Up We applications are getting more complex so the need for a dynamic program application is much needed. While choosing between NodeJs and Java, one has to understand the needs of the project. When the needs are clearly elucidated, the answers will have arrived at automatically. |
