In this post, Part 1 of Using Jest and Testing Library with React Native, I’ll give a brief introduction to Jest, Testing Library, and React Native. Then, we’ll walk through how to set each of them up. This will prepare us for Part 2, creating our first test.

Getting Started with Expo

Stewart Snyder JavaScript, Mobile, React, React Native, Tutorial Leave a Comment

Expo is a platform and framework that allows you to write cross-platform code using React Native, taking advantage of the APIs native to each platform. This makes it extremely simple to develop and deploy apps to a variety of platforms. Additionally, it allows the apps to make use of the native components of whatever platform they are deployed to.

This post first reviews the different features of Expo and how they can be used to rapidly develop and deploy software. Then, we’ll talk through the steps you’ll need to take to get up and running with the tool.

Decoding Mobile Development Options

Mike Cerny Development Technologies, Mobile, React Native, Xamarin 1 Comment

It can be challenging to decide on the right strategy for reaching the mobile audience, though. If you decide an app is what you need, the next question is “what are my options?” In general terms, the types of mobile applications you could choose to build can be divided into three groups: vendor-native, cross-platform, and hybrid web.

In this post, we give an overview of the various mobile development strategies on our shortlist for enterprise clients to consider; for example, Xamarin, Flutter, React Native, and Ionic. For each tool, we give a brief introduction and highlight the key advantages and disadvantages found in implementing each mobile development approach.

React Native With Expo

Lou Mauget Development Technologies, JavaScript, Mobile, React, React Native Leave a Comment

The React Native framework supports an installable mobile application created from JavaScript source code. It is not a React-based web app wrapper. It isn’t a code generator. There is no required application source code in Java, Objective-C, Swift, or Kotlin. Moreover, a single React Native application targets both iOS and Android devices.

In this blog, we show a quick-start that results in an executing application on a phone, within five minutes. That application is live-reloadable, native cross-platform, and written in JavaScript. It is not a web application.
