Local development

BEFORE JUMPING TO IOS OR ANDROID GUIDE, FOLLOW THESE GUIDES:

• https://facebook.github.io/react-native/docs/getting-started.html
• (Optional) https://facebook.github.io/react-native/docs/debugging.html#content
• npm install (you might need to use npm@2 version)
• npm dedupe (maybe necessary if you encounter Namespace collision error)
• cp env.example.js env.js and fill in the blank secrets in the file

iOS

The xcode-project is expecting that you have nvm installed. It can be reconfigured in Build Phases > Bundle React Native code and images.

• Install Cocoapods

• cd ios && pod install

• open wappuapp.xcworkspace

  Note: Use the .xworkspace instead of .xcodeproj!

Android

• Android Emulator suggestion: install and start Genymotion
• Or connect your Android device with usb cable
• react-native run-android

Common problems

Try these:

• Google: e.g. react native Naming collision detected almost always provides useful resources to fix problems
• Search react-native issues
• Search from the react native component's issues

• error: /Users/user/code/wappuapp/wappuapp-client/node_modules/react-native-vector-icons/Fonts/MaterialCommunityIcons.ttf: No such file or directory
  • Download the from here and move it to /node_modules/react-native-vector-icons/Fonts
• Cmd + R

Could not connect to development server

Make sure:

• React native packager is running (npm start)
• You have configured React native correctly: https://facebook.github.io/react-native/docs/getting-started.html
• Your mobile phone is connected to same wifi as your computer

Stuck at the white screen? It may take even minutes to do the initial load..

Error: Naming collision detected

Try to run npm dedupe.

Can't find 'node' binary to build React Native bundle

At least nvm causes this. Change Build Phases -> Bundle React Native code and images to:

export NODE_BINARY=node
. ~/.nvm/nvm.sh  # add this
nvm use 4        # add this (or whatever node version you are using)
../node_modules/react-native/packager/react-native-xcode.sh
