If you want run on Android Emulator, make sure you download Android Studio, setup a emulator and run it. Now, what you have to do is run the app on iPhone Simulator (on Mac) or Android emulator ( on Mac or Windows ). It will start up a ‘Metro bundler’ webpage on your browser like this. Now, you are ready, create a new React Native blank project on that directory, run this command to install, it might take a while to download.Īnd finally just try to start up the project with this command. You can use cd (change directory) to go to Home directory, see other files by hitting ls, make a new folder (if you may) called Expo by typing mkdir Expo, cd Expo to go to the folder. OK back to your terminal, now you need to know ‘where’ you are by hitting pwd command. Let’s get Started! 2.1 Create React Native App with Expo CLI If you on Mac, install Xcode throught the Mac App Store. Once the emulator is open, you can build from the Expo XDE run on the opened emulator. If you on Windows, follow this Android Studio emulator guide to set up Android emulator. While having the mobile client is good thing to see on your mobile device but, there is a need to use Simulator / Emulator on you platformto test out quickly the coding result.

Install Expo Mobile Client app for iOS or Android.

We gonna use terminal sparingly to install stuff.

Install Expo CLI with this command line.

Setup the environment might take some time. We will be using Terminal or Command Prompt sometimes, so be ready. Nevertherless, you might feel overwhelming with the tools that need to be installed on your computer. Using Expo make the development with React Native easier to get started. On the data-flow side it’s uses JavaScript engine to work on app’s logic.

React Native renders the UI elements into native based on platform. React Native is a framework to make a real native iOS and Android apps using JavaScript.
