In the code above, we created a TextInput to hold our to-do text and a ToucahbleOpacity to add the to-do item to our list of to-dos. Open your App.js file and enter the following code. All you need to do is download the Expo Go app, run expo start and then scan the QR code that shows up. You can run your React Native app on a physical device without setting up the development environment. It will take a few minutes to create our project, and then we can start building our React Native application.Įxpo allows us to build for both Android and iOS on Windows, Mac and Linux.

In this case, simple-ios-todo is the name of our application. You can then create your project by running expo init simple-ios-todo. You can do that by running the following commands: npm install -g expo-cli To get started with Expo, you first need to install Expo CLI. If you want to include native code in your application, it is better to go with vanilla React Native from the start.Īlternatively, you can use Flutter and Codemagic to build and publish apps for iOS without a Mac. However, when using Expo, you can’t create custom native modules beyond those that ship with the React Native API. Using Expo is the easiest way to get started with React Native.

Then in the Emulation Settings panel, select Dynamic Recompiler. For Mac users: In the Emulation menu, choose Emulation > Show Emulation Settings.For Linux users: add to command line “––cpu-mode=1″.For Windows users: in main menu, choose Config -> Emulation Settings, check “Use dynamic recompiler” or add to command line “––cpu-mode=1″.

Turn on JIT (dynamic recompiler) for HUGE speedup: It’s a terrible venue for that, and there are other places specifically designed for it, such as, say, the support forum

Notably, the save-related issues resulting in the advice “dont use 0.9.10″ have been resolved. In this version, we have focused on the Cocoa frontend, but there have been some good core fixes over so long.
