Getting Started

Prepare React Native Development Tools

The React Native documentation contains detailed instructions on how to prepare your computer for React Native development. Follow the instructions in the "React Native CLI Quickstart" for your specific platform.

If you are using a Mac, follow both the iOS and Android target instructions. Otherwise, you only need the Android target instructions.

Checkout develop branch & install node_modules

This project uses npm to manage Javascript dependencies (npm ships with Node).

cd edge-react-gui
npm ci
npm run prepare

Run the bundler

npm start

This bundler process needs to run in the background, so feel free to run this in its own terminal window.

Add API key in keys.json

A public API key is built into the edge-core-js which can be used to build and test the Edge app. This key is severely rate limited and should not be used for production. For production use, get an API key by emailing [email protected].

npm run prepare creates config.json (non-secret) and keys.json (secret) with defaults. Set EDGE_API_KEY in keys.json to the key you received from Edge. To use the public API key, leave EDGE_API_KEY blank. If you still have a legacy env.json, run npm run split-env-json once to produce the two files.

Run the app in debug mode

iOS

• Run npm run prepare.ios to generate the CocoaPods files. You will need to do this after the first install, and any time Xcode produces a The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation. error.
• Open edge-react-gui/ios/edge.xcworkspace in Xcode
• Choose a target device or simulator and tap the Play button on the top nav bar

Android

To build, install, and start the app on a simulator or physical phone with USB debugging, run:

npm run android

Otherwise, to get an APK, do:

cd android
./gradlew assembleDebug

• The resulting APK will be in ./app/build/outputs/apk/debug/app-debug.apk
• Copy the APK to a simulator like Genymotion or a real device via Email or messaging app

Build release version of app

iOS

• Open edge-react-gui/ios/edge.xcworkspace in Xcode
• Hold [ option/alt ] and click on the Edge button on the top bar to the right of the Play and Stop icons.
• Change 'Build Configuration' to Release
• Uncheck 'Debug Executable'
• Close window
• Choose a device and hit Play

Android

cd android
./gradlew assembleRelease

• The resulting APK will be in ./app/build/outputs/apk/release/app-release.apk
• Copy the APK to a simulator like Genymotion or a real device via Email or messaging app

Deploying (MacOS Only)

This repo includes several utility scripts that can be used in a CI/CD environment to build and deploy a release version of the app. The included Jenkinsfile utilizes all the scripts but you are free to use them in your own CI environment.

Update the version file

Set BUILD_REPO_URL to the URL of an empty Git repo that will hold a version file that will be auto updated to increment the version and build number. Then run the following to update a local release-version.json file

npm run gitVersionFile

Update the project files based on the version in release-version.json

npm run updateVersion

Build, sign, and deploy

The included deploy.ts is a script to automate building, signing, and deploying release builds of Edge. It provides the following:

• Auto sign Android APK with Android keystore files
• Auto sign iOS IPA with provisioning profiles
• Build release version of iOS and Android
• Upload iOS IPA and Android APK files to AppCenter for developer testing

To Use

• Set the env var KEYCHAIN_PASSWORD to the keychain password of the current user
• Copy the deploy-config.sample.json to deploy-config.json and edit the parameters accordingly. You'll need a HockeyApp account to get ids and keys
• Download a copy of the Google Bundle tool (https://github.com/google/bundletool/releases)
• Set the bundleToolPath in deploy-config.json to the path to the bundle tool .jar file
• Put any Android keystore files into edge-react-gui/keystores/
• If using Firebase, put your account's google-services.json and GoogleService-Info.plist into edge-react-gui/
• Install CocoaPods brew install cocoapods (use Homebrew, not gem install, so it survives Ruby upgrades)
• Install xcbeautify brew install xcbeautify

Run deploy

npm run deploy edge ios master
npm run deploy edge android master

Fastlane support

This repo uses Fastlane to automate iOS code signing. The deploy script uses fastlane match to install the signing certificates and provisioning profiles, and to renew them automatically when they expire (see Certificate renewal below).

Fastlane must be version 2.235.0 or newer (install or upgrade with brew install fastlane). Older versions ignore --skip_confirmation during match nuke, which blocks the automatic certificate renewal on an interactive prompt.

Authentication uses an App Store Connect API key, not an Apple ID. Place the key JSON at fastlane.json in the repo root (see the App Store Connect API docs). Then set the following environment variables and run npm run deploy as mentioned above

BUILD_REPO_URL          // Git repo used to store encrypted provisioning
                        // keys.
                        // Will be shared with the gitVersionFile.ts script
GITHUB_SSH_KEY          // (Optional) SSH Key file to use when accessing
                        // BUILD_REPO_URL
MATCH_KEYCHAIN_PASSWORD // Password to unlock the current users keychain
MATCH_PASSWORD          // Password used to encrypt profile information
                        // before being saved to the BUILD_REPO_URL

Certificate renewal

Apple signing certificates expire once a year. When fastlane match fails because a certificate is no longer valid, the deploy script automatically nukes that certificate type (revoking it on the Apple Developer Portal and wiping it from BUILD_REPO_URL) and re-runs match to generate a fresh certificate and provisioning profiles.

Debugging

As with any modern React Native app, Flipper is the officially-supported debugging app. Use the "React Native Hermes Debugger" to debug Javascript running in the UI.

If you want to inspect Redux, you can install the redux-debugger plugin for Flipper, which this app supports.
