Core Components and Native Components

This content has been made available for informational purposes only. Learners are advised to conduct additional research to ensure that courses and other credentials pursued meet their personal, professional, and financial goals. A View is useful as a container for other components, to help control style and layout.

However, that often introduces too much abstraction, requires you to jump between different files, and makes reusing components more difficult. I’ve built the course that I would have wanted to take when I was learning React Native. A course that explains the concepts and how they’re implemented in the best order for you to learn and deeply understand them. In react native, data only flows in one direction, from the parent to the child. Sometimes a component may need to accept data from another source, however. Implementing a “Friends Around Me” app can be another great way for complete beginners to get started with React Native.

Why Invest in Mobile Applications?

OS X and iOS developers can actually directly interface with it if they want to. Once you get familiar with the syntax, start with creating mini-projects like a tip calculator or password generator. As you practice, the more you will understand and come across challenges. If you get stuck in a problem, you can search on the web, as most of the solutions are already available. Once React basics are covered, you can dive into advanced topics like context, component patterns, portals, and component testing.

Running react-native init HelloWorld creates a folder called HelloWorld in which the boilerplate code can be found. In addition to props, components can also have an internal state. The most prominent example of that behavior would be a click counter that updates its value when a button is pressed. To build the content of a component, React provides properties or props for short. Similar to XML attributes, we pass in the props directly to a component and can then use the props inside the constructed component. The special thing is that we don’t mess with DOM elements here, but we return an XML-based construct that represents what will be rendered in the DOM.

What Are the 5 Key Concepts of React Native?

It also speeds up development time as it includes pre-developed components, which are included in the open-source library. React Native (also known as RN) is a popular JavaScript-based mobile app framework that allows you to build natively-rendered mobile apps for iOS and Android. The framework lets you create an application for various platforms by using the same codebase.

Any component that renders other components is a parent component. Here, Cafe is the parent component and each Cat is a child component. On Android, you usually put your views inside LinearLayout, FrameLayout, RelativeLayout, etc. to define how the view’s children will be arranged on the screen.

React Native – one framework to rule them all

You may have two or three software specialists at your disposal, and your chief goal is to develop a high-quality, stable app and ship it ASAP to the market. Because of the multitude of features and their complexity, Walmart would normally have to maintain two enormous dev teams to keep the app going on all devices. Instead, they decided to take advantage of cross-platform development with React Native. Below, we’re presenting some examples of world-famous companies who are already leveraging React Native in their projects. Go through them and you will see how the framework has helped them attain different business goals.

  • While it may come as a surprise – after all, React Native is used by top tech players – it’s still in beta phase.
  • Sencha is also running a blog featuring company news, product insights, and additional resources, and provides the users with a discussion forum.
  • React Native falls in-between native and hybrid applications on the mobile app spectrum.
  • You will then decide which bundling modules will specifically suit your project.
  • By default, the primary axis is the vertical one, and the secondary axis is the horizontal axis (you can change that by setting the flexDirection property to row).
  • Additionally, Facebook shares a tutorial to help newbies easily kick off their first RN project.

In terms of performance, it’s slower than React Native as it uses WebView, but the good news is, you can test the code on any browser. Most of the time, React Native will work very well for you even if your app eventually grows into a highly-sophisticated, complex solution. After all, companies like Facebook and Skype have found much success with the framework and have been using it consistently for many years. That being said, some companies have decided to back out from using React Native. UberEats is another application that is based on React Native development. It differs from the Uber app in that it includes three parties instead of just two – restaurants, delivery-partners, and diners.

Tips for how to learn React Native

React Native is highly readable, which makes it easier to learn, especially in the case of less experienced programmers.10. Expanding CommunityLast but not least, thanks to the fact that React Native provides a positive coding experience, it enjoys massive support from the developers’ community. What’s more, the project receives constant support from Facebook so that it’s continuously improving. In mobile application development, a native app is a software created for a specific platform or device.

The overlap of developers who are excellent on all mobile platforms is insignificant. On the other hand, RN is based on the ‘learn once, write everywhere’ approach. What this ultimately means is that with the framework you don’t need to maintain separate teams to release a product on several OSs. As Discord’s case demonstrates, with RN it takes only two people to build powerful apps with RN and deploy them on all devices. In my opinion, you need to learn React before starting with React Native. It would be beneficial to have a basic understanding of React before diving into React Native.

React Native Features

That being said, you don’t need to be an expert in React or JavaScript to learn React Native. As long as you have a basic knowledge of these technologies, you should be able to get up and running with React Native. Now, let’s take a closer look at these technologies individually so that you get a better idea of how to prepare before learning React Native. Most components can be customized when they are created, with different parameters. Now that you’ve covered both React and React Native’s Core Components, let’s dive deeper on some of these core components by looking at handling . You might’ve noticed that although isHungry is a const, it is seemingly reassignable!

You can use an existing mobile app to serve as inspiration, such as Tasty, Yummly, and Cookpad. Don’t forget to also browse Mobile Templates, UI8, Dribbble, and Behance for more mobile design inspiration. A simple Recipes app only requires you to list the recipes along with their details. You can enable users to navigate to the detailed screen of each recipe in the list when clicking on the recipe list.

React Native comes with a set of essential, ready-to-use Native Components you can use to start building your app today. React Native ships with ES2015 support, so you can use this stuff without worrying about compatibility. Import, export, const and from in the example above are react native concepts all ES2015 features. If you aren’t familiar with ES2015, you can probably pick it up by reading through sample code like this tutorial has. You can add state to a component by calling React’s useState Hook. A Hook is a kind of function that lets you “hook into” React features.
