React Native Blueprints

By: Emilio Rodriguez Martinez

Overview of this book

Considering the success of the React framework, Facebook recently introduced a new mobile development framework called React Native. With React Native's game-changing approach to hybrid mobile development, you can build native mobile applications that are much more powerful, interactive, and faster by using JavaScript This project-based guide takes you through eight projects to help you gain a sound understanding of the framework and helps you build mobile apps with native user experience. Starting with a simple standalone groceries list app, you will progressively move on to building advanced apps by adding connectivity with external APIs, using native features, such as the camera or microphone, in the mobile device, integrating with state management libraries such as Redux or MobX, or leveraging React Native’s performance by building a full-featured game. This book covers the entire feature set of React Native, starting from the simplest (layout or navigation libraries) to the most advanced (integration with native code) features. By the end of this book, you’ll be able to build professional Android and iOS applications using React Native.

Preface

Linting and code formatting


Writing clean, bug-free code is challenging. There are a lot of pitfalls that we may face such as indentation, importing/exporting misses, tags not closed, and so on. Having to overcome all of them manually is a tough job which can distract us from our main purpose: writing functional code. Luckily, there are a handful of very useful tools to help us with this task.

The tools we will be using in this chapter to ensure our code is clean will be ESLint (https://eslint.org/) and Prettier (https://github.com/prettier/prettier). 

ESLint will be in charge of identifying and reporting on patterns found in the ES6/JavaScript code, with the goal of making the code more consistent and avoiding bugs. For example, ESLint will flag any use of non-declared variables, exposing the error while we are writing code instead of waiting until compilation.

On the other hand, Prettier enforces a consistent code style across your entire codebase because it disregards the original styling...
