Overview of this book

React Native's ability to build performant mobile applications with JavaScript has resulted in its popularity amongst developers. Developers now have the luxury to create incredible mobile experiences that look and feel native to their platforms with the comfort of a well-known language and the popular React.js library. This book will show you how to build your own native mobile applications for the iOS and Android platforms while leveraging the finesse and simplicity of JavaScript and React. Throughout the book you will build three projects, each of increasing complexity. You will also link up with the third-party Facebook SDK, convert an app to support the Redux architecture, and learn the process involved in making your apps available for sale on the iOS App Store and Google Play. At the end of this book, you will have learned and implemented a wide breadth of core APIs and components found in the React Native framework that are necessary in creating great mobile experiences.

Chapter 3. Our Second Project - The Budgeting App

Staying within a monthly budget is something that I've found difficult to do in the past. For our second project, we will build an app that keeps track of our budget by letting us set a goal for how much we'd like to spend in a month, and then lets us enter expenses into the application and categorize them under simple labels. At any point, we can go and look at how we're doing for the month and look at our previous months' results.

In this chapter, we will cover the following topics:

  • Planning our second app, Expenses
  • Installing a popular vector icon library for React Native
  • Building a series of helper methods that will be used throughout our app
  • Creating a modal that lets us enter our expenses
  • Rendering a list for the current month, showing the month's progress
