React Image Loading Optimization Techniques

I am, by trade, first and foremost a (native) Android developer and have been working for 6+ years for a whole range of companies and projects.

One of the challenging problems in the world of development is that if you want to create an app and be a serious player in the market you kind of need to develop for iOS and Android. And additional questions might rise like: Should I also create a website? Or when you want to create a website you at least should make sure it looks good on mobile devices. And should I maybe first focus on _mobile first… _since arguably most of users that hear about your site will first want to try and visit it via their mobile device?

In all the companies I have worked each platform (iOS/Android/Web) had their own development team. And each team was usually solving a lot of the same challenges and there was very little exhange of ideas or code. and it seemed the bridge to figure out a way how to combine or reduce work effort was unable to be gapped due to the nature of the difference in language used.

So one of the questions that has occupied my mind is: “Is there a way that I can setup my project in such a way that I can create a site/app so that it 1. Looks good on desktop/laptop 2. Can be used on Android as well as iOS devices 3. Keeps in mind that most users will want to visit it via there mobile devices.

The obvious answer, and one that alse has the added benefit of not having to deal with the additional work that comes along with publishing to Google Play or Apple’s app store, is to create a web based application users can visit via their webbrowser.

Facebook does it… and with a level of user experience good enough for what I would want to achieve for my platform… so why wouldn’t I be able to do it… ;)

So I decided last year to start and learn React JS and some backend development and set out to see if I can create the metacules.com platform.

These writing here portray some of the adventures in the world of React JS.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

10 Best React Loading Component for Your App

While instant feedback from an app or website is best, sometimes your product won’t be able to adhere to speed guidelines. The slow response may be due to poor internet connection or the operation process may take a long time. For such cases, the designer must reassure the user that:
The application is working according to their requirements and the actual process is still active.

If you are unable to shorten the process, you should at least try to make the wait pleasant for your users. Here are 10 react loading components for your react.js application

1. Create React Content Loader

Have you heard about react-content-loader? It’s a SVG component to create placeholder loading, like Facebook cards loading or also known as skeleton UI. So now you can use this online tool to create your own loader easily. You just need to draw using the canvas or code using the live editing!

How to Select and Hire the Best React JS and React Native Developers?

Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.

What is React.js?

Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.

React vs React Native

• React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
• React.js and React Native have similar syntax and workflows, but their implementation is quite different.
• React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
• React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.

What is the Average React Developer Salary?

In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.
