Exploring React.JS App Development Best Practices

React churls up cross-platform application development with its commoving UI’s on the web and ‘near-native’ effect by its native counterpart; let’s learn more!



Exploring React.JS App Development Best Practices

React churls up cross-platform application development with its commoving UI’s on the web and ‘near-native’ effect by its native counterpart; let’s learn more!

React sweeps up rendering logic with UI logic, handling events, changing states and preparing data for display.  React separates concerns instead of artificially separating technologies by putting mark-up and logic in separate files, and loosely couples all “components”. JSX is not mandatory, but it helps as a visual aid, working besides UI within JavaScript code. It facilitates error handling. With that out of the way, you can embed expressions, specify attributes, specify children, prevent injection attacks, and represent objects with JSX.   

What should you know to get started?

With a bit of understanding of core Java, Spring Boot, Servlet, Filter, XML, and JavaScript React.JS framework can easily be assimilated into start-up and enterprise application development.

As we scope the use cases and applications of React, JSX is one of the syntax extensions to Javascript. It is used along with React to describe what the UI should look like. It fosters template language, produces react “elements”, and renders them to DOM.

Popular React Application

Metaverse is a collective project that leverages immersive learning, responsible innovation, inclusivity, transparency, empowerment, and accesses technologies, and unlocks opportunities as learners, creators, and developers to build a 3D space to let you socialize, learn, collaborate and play in ways that go beyond what we can imagine. React.JS empowers Metaverse.

React JS with Spring Boot 2.2

Enterprise Java developers use Spring Boot 2.2 and React JS to develop backend RESTful applications using Spring Boot 2.2 and frontend applications using the React JS framework.

To start using Spring Boot 2.2, customize auto-configuration, configure data and CRUD operations, create REST APIs with Spring, secure REST APIs, test Spring Boot Application, create and style React components, consume REST API with React JS, deploy and containerize application.

React JS with TypeScript

TypeScript supports JSX and models patterns used in React codebases like ‘useState’. Next.js and Gatsby also support React in the way TypeScript does. Typescript is a superset of JavaScript and it is not comparable to JSX.

React.jsx is the same as React.js with an upgraded extension. It makes us easier to differentiate between XML, HTML, and JS. TypeScript adds more functionality to plain JavaScript. JSX version is React is better known to compile to vanilla Javascript. It assists in static type checking in case of larger projects, better IntelliSense, debugging support, interoperability amongst JavaScript to TypeScript with renaming from .js to .ts.

React.js and React Native

React.js is an open-source JavaScript-based library for building user interfaces for single-page applications. It handles the view layer for web and mobile apps. It allows using reusable UI components. With react Native you can build mobile apps that are executable on iOS and Android. 

React Native is a form of React Javascript library used for creating native mobile apps. It is closely differentiated from PhoneGap (Apache Cordova), and Appcelerator titanium that uses JavaScript to create iOS apps. Unlike PhoneGap, in React Native the code is written in JavaScript but the app’s UI is fully native. It does not have drawbacks that are typically associated with a hybrid HTML5 app.

Functional App Development with React

React’s approach to building interfaces is highly functional, and the UI is a function of the current app state, which is directly proportional to a component’s state change. This improves performance. React re-renders the component and its child component, even when the state change does not directly affect the child component.


React wraps functional components in ‘React.memo’ to prevent unnecessary re-renders if the prop it receives never changes.

State Variable

React also implements the functional concept when updating a state variable, especially when a value is based on the previous one.

State Value

React also passes the callback to the updater function, to enable access previous version of the state and update the state value.

State Change

React is a reactive library that reacts to state changes to keep the DOM updated. And we update the state using the ‘setState()’ method in a class component or the updater function in a functional component.

Mutable States

React handles mutable states by making a copy of the state data and computing the output based on the copy. It never modifies the original data.

Prop Arguments

Above everything, functional programming codes in React are pure. It goes by receiving a prop as an argument and computes the output based on the input prop. A pure component can make computations that affect and modifies some state outside of its scope, as in data fetching, and manually manipulating the DOM.

Side Effects 

React does not allow performing side effects (updating title to reflect the updated count value) directly inside the body of a component to avoid inconsistencies in the app. It comes with a Hook called useEffect to manage all such side effects.

Conclusion: How do ReactJS development companies roll up React?

ReactJS App development can be formulated in multifarious ways. It can either be with JavaScript, TypeScript, Spring Boot or any other framework, that gels up and leverages React offerings.

  1. It starts with autoconfiguration via CLI and actuator,
  2. creating, and securing REST API with Spring Boot 2.2 and DevTools,
  3. Exploring Spring Boot Auto Configuration and Customization,
  4. Creating application profiles based on the environments,
  5. Configuring backend data using JDBC and Spring Data JPA,
  6. Configuring a DataSource for H2 DB, and also for Maria DB,
  7. Designing a REST architecture based application,
  8. Creating a REST application using HATEOAS,
  9. Consuming REST APIs endpoints with RestTemplate, Traverson, and WebClient,
  10. Exploring JWT web token for the RESTful APIs and exploring how to secure REST APIs using OAuth2 and Spring security,
  11. Creating TESTING module of the Spring Boot application and Unit & Integration testing,
  12. And finally deploying the application to the cloud platform (PaaS).
  13. Containerization and Deploy using Docker containers

However, app development companies find it difficult to debug React applications, especially when user experience issues are even more difficult to reproduce. Try using tools to monitor and track the Redux state, that automatically surfaces JavaScript errors, and track slow network requests and component load time.

Tips for Finding the Best Laptop for Your Business



Best Laptop for Your Business

It is all too easy to click on the best-selling laptop pushed into your lap by retailers, but is that going to be the best fit for your business? To truly synchronise your needs with your tech device, you have to understand what you are buying, especially when it concerns something as important as your company. You don’t have to own a degree in computing to be able to discern what boxes to tick in your business laptop search and this guide details what you should be looking for. 

What Do You Need the Laptop For?

Are you the admin brain behind your company, sending emails to clients and creating invoices or work regimes? Or does your career take you down a creative path, such as media design or geographical planning activities? Whatever the answer, the laptop you pick has to reflect those needs. A GIS supportive device will ensure that any GIS software is fully supported, or a laptop with a stronger GPU will ensure that graphics rendering is never a hindrance. These types of roles have a higher demand for a stronger CPU than a lesser demanding role functionality wise, for example, if you do lots of report writing. 

Simply put, if you need your laptop to perform basic tasks such as typing, reading, or similar, then things like CPU, RAM, GPU, and even GIS will not be as important. However, if you are creating graphics, and work with media files or GIS software, there is an elevated need for a more technical laptop that can keep up with the complex jobs too. 

Shopping for Your Budget

There are three ranges of laptops, low-budget, mid-range, and high-end models. Ideally, because of the purpose of this purchase, low-end models should be overlooked wherever possible. Starting at mid-range laptops means committing to a price of at least $350 and upwards, whereas the high-end models market at $600 and rising. The money you put into this asset should be seen as an investment, with the return being the profits from the work tasks carried out at the helm. For a deeper look at what a good price range can get you, check out these Lenovo Small Business Laptops and see how the specs hold up to the price tag.  

What is a Good Business CPU?

The Central Processing Unit is the power behind the device. Which CPU you need depends on what you do with your device. If, say, a typical workday entails having multiple browser windows open simultaneously alongside complex software and an open inbox, your CPU demands immediately shoot up. If you spend the day typing up documents and sending sporadic emails, the CPU can stay put at the lower end. Most business owners will benefit from a Core i3 or i5, but the i7 is there for those needing an extra boost. The higher the CPU, the higher the price in most cases, but this is where it is worth putting your money. 

Where Will You Use the Laptop?

If you work at home, the laptop you buy won’t need to be geared towards portability or ruggedness. However, people who travel to an office every day, or worksites, or take their work all over the world with them, need something sturdier. It is possible to find a lightweight laptop that is still rugged and therefore supports portability.  

Which Design Suits Your Needs?

Business laptops come in a whole manner of designs, including standard, and hybrid models. Touchscreen laptops are becoming more popular than ever before, largely owing to their multi-faceted opportunities and flexible usage allowances. They can be used as a tablet, or laptop in the same sitting and have been a real innovation in the world of business. Traditional models still have a lot to offer and tend to be more rugged generally, but lots of business owners prefer the versatility of the hybrid models. 

Your business needs the best supporting tools so it can perform to its optimum capacity. The laptop product is one of the biggest decisions to be made whether that is as you are starting out or a replacement device down the road. Consider all your options and remember to siphon out what is relevant and what can be pushed to the side.

This is what determines how well the laptop performs, how long it’ll last, and how much it’ll cost to run. The choice of screen refresh rate is largely dependent on the components of a PC such as the GPU and the CPU. Generally, a refresh rate of 60 Hz is considered the Holy Grail for laptop displays. But for modern-day gaming and content consumption, 144Hz is quickly becoming the new standard.

If you are a creative professional or a passionate gamer, you must have heard the terms FPS (frame rate per second), response time, and screen refresh rate. New buyers are often more fixated on the GPU and the processor but ignore the importance of a smooth screen display which has a great impact on the gaming experience. High refresh-rate gameplay is one of those things you have to experience firsthand to truly appreciate. Visuals are buttery smooth and controls feel more responsive when playing at 90 or 120fps, and the benefits only increase the higher the frame count goes. But in order to achieve such high frame rates, you need the right hardware, including a high refresh-rate display and a graphics card and processor fast enough to handle the task. Gamers don’t just want a powerful processor, they want a powerful processor backed up by equally powerful memory.
