Getting Started with Expo

Stewart Snyder 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.

Push notifications are a vital feature for today’s enterprise mobile applications. Why are they so important? They allow the business to communicate with its users without requiring the application to be in an open state.

In this blog, we go through a step-by-step tutorial for setting up and configuring push notifications on Xamarin.Forms applications using Azure Notification Hub. Let’s dive right in.
