Since react allows you to write and share most of the code between platforms, you can develop Android and iOS apps simultaneously with react native.Ī combination of JavaScript and XML markup called JSX also can be used to write applications using react native. This means that web developers use JavaScript libraries to create native-looking mobile applications. The react framework, which was developed by Facebook, is primarily focused on mobile platforms instead of browsers. Understanding react native before getting into camera appĭevelopers use react native framework to write native applications for iOS and Android that are natively rendered using JavaScript. In this blog post, you'll learn about everything related to building a native camera application for iOS and Android.īefore we get started, it is important to mention that this tutorial is a step-by-step guide for developers who are relatively new to the react-native camera app. There are a lot of things that you have to learn to complete the camera app successfully. You don't want to end up on GitHub, staring at big empty boxes of code as you try and figure out how to make one. If you're new to react native, it can be overwhelming and confusing. Feel free to have a look at its source code here.Building a react native camera app from scratch is a challenging task. I've also created a Open source Book Searching React Native app in which I used these placeholder components as loaders. You can customize these placeholder components according to your need or app theme.įind the source code in the Github repo here. This is just a simple implementation of placeholders screens as loaders. We have successfully created a React Native app that uses rn-placeholder to show placeholder as loaders during data fetching just like facebook, Netflix and other popular apps. So during the data fetching BookCardPlaceholder will be rendered and when the data is fetched successfully BookCardComponent will be rendered by the FlatList. This is what the users will see during the data fetching. In renderPlaceholders() we'll render BookCardPlaceholder using the map function. In renderX() we'll return a FlatList which will render the list of Books using renderBookComponent. Let's set up a new Expo project using expo-cli.Įxport default function App () Make sure to update expo-cli if you haven't updated in a while since expo releases are quickly out of date. Node.js (>=8.x.x) with npm/yarn installed.To follow this tutorial, please make sure you have the following installed on your local development environment and have access to the services mentioned below: We will also use Google Books API to fetch some books data. In this article we will be learn how to implement placeholder screens using rn-placeholder library. If you want to read more more on how to use it read this article. To make these loaders interesting, I created a React Native package that uses Airbnb's Lottie and Modals to create beautiful animated loaders. However, as a user and as a developer, I find them to be too mundane and old fashioned. In most cases, using the good Ol' ActivityIndicator along with React Native modal would suffice. You might have seen these kinds of loaders in apps like Facebook and Netflix. This pattern of using placeholder improves the user's perceived experience when waiting for something to load. The latest trend is to show placeholder/skeleton screens as loaders. When building mobile apps, we often use loaders, progress bars, loading indicators to tell users when something is happening or loading. Users expect their apps to be blazing fast since no one enjoys waiting. A good user experience is what separates a awesome app from a regular one.
