This project was bootstrapped with Create React Native App.
npm start
Runs the app in development mode.
Open it in the Expo app on your phone to view it. It will reload if you save edits to your files, and you will see build errors and logs in the terminal.
Sometimes you may need to reset or clear the React Native packager's cache. To do so, you can pass the --reset-cache
flag to the start script:
npm start -- --reset-cache
# or
yarn start -- --reset-cache
npm run ios
Like npm start
, but also attempts to open the app in the iOS Simulator if you're on a Mac and have it installed.
npm run android
Like npm start
, but also attempts to open the app on a connected Android device or emulator. Requires an installation of Android build tools (see React Native docs for detailed setup). We also recommend installing Genymotion as your Android emulator. Once you've finished setting up the native build environment, there are two options for making the right copy of adb
available to Create React Native App:
adb
Settings -> ADB
. Select “Use custom Android SDK tools” and update with your Android SDK directory.adb
/Applications/Genymotion.app/Contents/MacOS/tools/
.npm run eject
This will start the process of "ejecting" from Create React Native App's build scripts. You'll be asked a couple of questions about how you'd like to build your project.
Warning: Running eject is a permanent action (aside from whatever version control system you use). An ejected app will require you to have an Xcode and/or Android Studio environment set up.
