We’ll use these illustrations along the course when building components. First of all, ES2015 (also known as ES6) is a set of improvements to JavaScript that is now part of the official standard, but not yet supported by all browsers, so often it isn’t used yet in web development. React Native ships with ES2015 support, so you can use this stuff without worrying about compatibility.

At present React Native is used with some popular apps like Facebook mobile app, Instagram, Pinterest, Skype, etc. Through the course of this book, author Stoyan Stefanov helps web developers and programmers build a complete custom app for storing data on the client. You’ll quickly learn why some developers consider React the key to the web app development puzzle.

Developer Notes​

Please keep in mind that using a lot of ternary operators may make your code unreadable, and you should try to avoid overusing them. When defining the bottomContainer style, I already mentioned making our app responsible and flexible. We’ll also cover this in a later section of the course, but the layout needs a fix ASAP. We can use hardcoded values for now as the value of the  – we’ll make these display the correct value later in the “Persisting data” section. Call the this.generateNewRound() at the top of the componentWillMount() to make sure that the game initializes a round when the player opens the screen. You can add more margin to make the game harder or get rid of it to make the game very-very easy, but I think the 2-pixel margin is just ideal for a fun gameplay.

Along the way, you’ll build several increasingly sophisticated sample apps with React Native before putting everything together at the end. We’ll build the “Awesome Places” app in this course, an app where users can share amazing pictures and the location where they took them. This app will allow you to see things like using maps, the camera, user authentication, connecting to a server and much more in action. React Native – The Practical Guide certification https://www.globalcloudteam.com/ course is created by Maximilian Schwarzmüller – Professional Web Developer & Instructor and Academind by Maximilian Schwarzmüller and is made through Udemy. React Native – The Practical Guide online course is for candidates who want to learn how to create native mobile apps for iOS and Android using React and JavaScript. We’ll build the “Awesome Places” app in this course, an app where users can share amazing pictures and the location where they took them.

While we do our best to assume no prior knowledge of React, Android, or iOS development, these are valuable topics of study for the aspiring React Native developer. Where sensible, we have linked to resources and articles that go more in depth. You can start here and read through these docs linearly like a book; or you can read the specific sections you need. You can leverage Live Reload if there are bigger changes to add to the app logic so that your app reloads upon changing the code. React.js was originally developed by Facebook team to create a highly responsive and dynamic UI with uncompromised performance.

• Since we aren’t aiming production nor planning to write native code in our project as we’re only building an example project, Expo is the fastest way to start off, thus we’re going with it.
• If you want to check out the code that’s finished as of now in one piece, here’s the GitHub repo.
• If using Fragments is a new concept for you (it may be because it’s a relatively new concept in React), be sure to check out the docs.
• Because the Header does not need an internal state, we can define it as a stateless functional component.
• Straight to the point, the explanations are really clear I like it great teacher Muy buena explicación, fácil, entendible good This is great step by step instruction.

You can use a simulator or a device with Expo Client installed, whichever you prefer. I’ll call it colorblinder as this is the name of the game we’ll work on along the series, but you can call it whatever you want. They also have an online playground named Snacks where you can try out other people’s code online, or work on bite-sized projects without the need of creating a project in the CLI. As you may have already noticed, the React-Native documentation features Expo CLI as the default toolchain to get started. Let’s take a look at what’s Expo, where does it come from, and why is there a 3rd party in the official documentation.

In this series, we’ll cover the basics of React-Native development, compare some ideas with React, and develop a game together. By the end of this tutorial, you’ll become confident with using the built-in components, styling, storing persisting data, animating the UI and many more. The process of mobile app development using React Native framework is swimmingly fast. Building the complex UI design elements in React Native is also quick as it usually is with React JS across both iOS and Android.

This book is for developers who want to learn the React library while learning the latest techniques currently emerging in the JavaScript language. The ecosystem is exploding with new tools, syntax, and best practices that promise to solve many of our development problems. Our aim with this book is to organize these techniques so you can get to react native – the practical guide [2022] work with React right away. We’ll get into state management, React Router, testing, and server rendering, so we promise not to introduce only the basics and then throw you to the wolves. We need to add 1 point and 3 seconds to the timer if the player taps on the right tile, then generate a new color and increase the size of the grid if needed.

React Native – The Practical Guide 2022

Compared to React JS that allows you to play with creative animations, React Native offers you good freedom to do a lot more in animation space. This suggests that while components are different, their syntax and workflow remain similar.

By learning how to use ReactJS to build real native mobile apps for iOS and Android without the need for platform-specific languages, you’ll position yourself as a versatile and efficient mobile app developer. This is just a basic example to demonstrate how React Native components are structured and how they handle user input. In a real application, you would build more complex and fully functional components to create engaging and interactive mobile apps.

Mobile apps are one of the best ways to engage with users – no wonder everyone wants to build one. By the end of the course, we’ll of course also go through all steps required to get it into an app store. In addition, hot reloading enabled by React JS comes handy when there is a need to make small changes to overall app styles. Rapid app development seekers would be happy to use React in their native project since you already get a few great tools without actually installing anything. With React Native, developers can animate components in the app by using the Animated API. There is quite known JavaScript library Velocity.js that you can use and compare Animated API with it.

After you pasted in the assets and open the app, you may notice that the sizing of the splash screen is a bit off, so before we start initializing our home screen, we should fix that. In the app.json under the splash property, set the backgroundColor to #0a0a0a. Some mockups I made before starting the development, just to illustrate the main idea.

Splitting the Home screen

The generateSizeIndex() generates a new number between 0 and the size passed as an argument. The generateNewRound() creates the data needed for a new round (differentiating tile index and color) and modifies the state to match it. This will run every time the user taps on the correct tile, and when initializing the game for the first time. When you’re building a React Native app, you’ll be making new components a lot. If you have training or experience with React and Javascript, this course is an excellent bootstrap into the mobile app development world using React Native. In today’s digital era, mobile app development has become a vital skill for IT professionals, and React Native is at the forefront of this revolution.
