Hands-On Design Patterns with React Native

View Patterns

One very demanding skill is writing good view code the first time around. It comes with experience and becomes almost automatic at some point. Hence, it is vital to do it right from the beginning. In this chapter, we will explore best practices and go through the React JSX patterns that you already used in the previous chapter. We will also focus on the broader spectrum of built-in components, which include input and forms. At the very end, I will show you a nice tool called a linter that is essential for any new frontend project.

In this chapter, you will learn how to do the following:

  • Write concise JSX
  • Use common React Native built-in components
  • Create simple forms using TextInput
  • Distinguish between controlled and uncontrolled input
  • Create error boundaries
  • Eliminate Mixins from your code base
  • Set up a linter to enforce your code style guide
...

Technical requirements

In this chapter, you will learn about various patterns, along with their code snippets. However, to run them, you will need the Create React Native App package. I have separated every example into a standalone application that you can launch on your phone or simulator.

To follow along with the examples in this chapter, you will need the following:

Follow the installation and running instructions from the GitHub page to get started.

Introduction to JSX

We have been using JSX so far, but what does it mean? JSX stands for JavaScript extension. How can it be an extension?

As you probably know, ECMAScript is also an extension to JavaScript (kind of). ECMAScript transpiles to JavaScript. What does this mean? It means that it just transforms ECMAScript code into valid JavaScript code. JavaScript misses out on many features that we like from ECMAScript, such as arrow functions, classes, and destructuring operators.

JSX works the same way. JSX is being transpiled to JavaScript, and its main feature is creating React elements based on the markup you write.
Could we use only JavaScript? Yes. Is it worth it? Most likely not.

Let's check this out in action. This is JSX and ECMAScript:

export default () => <Text style={{marginTop: 30}}>Example Text!</Text>

Now, compare this to pure JavaScript:

export...

Built-in components you need to know about

React Native is growing fast and changing often. I have selected a curated list of components that are likely to stay within the API for a long time. We will spend some time learning them so that we will be able to proceed faster later on in this book. Any further examples will rely on these components and will assume that you know what these components are for.

The ScrollView component

So far, we know about three components: View , Text, and StyleSheet. Now, imagine a case where we have a lot of rows to show in the application—something such as table of information pops into my mind. Obviously, it will be a long table, but the screen is small, so we will make it scrollable...

Key benefits

  • Mobile development in React Native should be done in a reusable way.
  • Learn how to build scalable applications using JavaScript patterns that are battle tested.
  • Try effective techniques on your own using over 80 standalone examples.

Description

React Native helps developers reuse code across different mobile platforms like iOS and Android. This book will show you effective design patterns in the React Native world and will make you ready for professional development in big teams. The book will focus only on the patterns that are relevant to JavaScript, ECMAScript, React and React Native. However, you can successfully transfer a lot of the skills and techniques to other languages. I call them “Idea patterns”. This book will start with the most standard development patterns in React like component building patterns, styling patterns in React Native and then extend these patterns to your mobile application using real world practical examples. Each chapter comes with full, separate source code of applications that you can build and run on your phone. The book is also diving into architectural patterns. Especially how to adapt MVC to React environment. You will learn Flux architecture and how Redux is implementing it. Each approach will be presented with its pros and cons. You will learn how to work with external data sources using libraries like Redux thunk and Redux Saga. The end goal is the ability to recognize the best solution for a given problem for your next mobile application.

Who is this book for?

The ideal target audience for this book are people eager to learn React Native design patterns who already know the basics of JavaScript. We can assume that the target audience already knows how to write Hello World in JavaScript and know what are the functions, recursive functions, JavaScript types and loops.

What you will learn

  • Explore the design Patterns in React Native
  • Learn the best practices for React Native development
  • Explore common React patterns that are highly used within React Native development
  • Learn to decouple components and use dependency injection in your applications
  • Explore the best ways of fetching data from the backend systems
  • Learn the styling patterns and how to implement custom mobile designs
  • Explore the best ways to organize your application code in big codebases

If you are new to React Native I would advise you not to purchase this book. The book is poorly written and the code being used is highly complex.If you are a seasoned React Native Developer this is a must buy. Although the book is poorly written you should be able to follow the examples and get a feel for what the author is trying to accomplish. You can also google the code source if you get lost. I learned a lot after the 1st chapter.This is a MUST BUY for seasoned developers.

Not an very good book. It has some good information on it, but the way it’s presented is not optimal. Some key concepts are not very well explained.Also, if you don’t know JavaScript well enough, you need to start with a different book.Still, it’s worth reading.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter.

What is Early Access? Chevron down icon Chevron up icon

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
