Haven

Haven is a mobile app that runs the decentralised marketplace, OpenBazaar. It is composed of two major parts:

1. The react-native client (i.e. this repository)
2. The Golang OpenBazaar server, which is compiled into a library/framework for iOS and Android devices using gomobile

The app enables users to access a global decentralised marketplace for goods and services, where they can use a variety of supported cryptocurrencies (BTC, BCH, LTC, ZEC, ETH) for payments. Haven also directly access supporting third party services to improve the user experience:

• OB1 search
• A social feed powered by https://getstream.io (and supporting middleware built by OB1 for authenticated access)
• Deeplinking support provided by Branch.io
• Opt-in metrics via Countly
• Wyre plugin for topping-up the wallet with cryptocurrency

Setup Instructions:

1. Clone the repo

• https://github.com/OpenBazaar/haven

2. Install npm and pod dependencies

cd haven
yarn
cd ios && pod install

3. Copy .env file to the root directory

• If you want to run the prod target, the env file name should be .env.prod. The env file should look like this:

BRANCH_KEY=
COUNTLY_ROOT_URL=
COUNTLY_APP_KEY=
STREAM_API_KEY=
STREAM_APP_ID=
HMAC_SECRET=

4. Copy those files into havenBuildConfigFiles folder:

AppCenter-Config.plist
GoogleService-Info.plist
appcenter-config.json
google-services.json

5. In havenBuildConfigs folder, run copy_files.sh
6. Run the app: react-native run-ios

iOS

Then you'll need to set up iOS simulator (Xcode). The app can also be installed on your device, but the default is not a static build, meaning it will need to be connected to Xcode to function. Static build instructions can be found here.

In Xcode, run the project on a simulator or install on your device.

Android

Setup Android USB debugging mode and make sure adb is installed on your computer. Plug in your Android device into your computer, make sure that your computer recognizes the device (type in adb devices), and run: react-native run-android.

Again, static builds for Android haven't been compiled yet, but further instructions are here.

Building Android

The application most easily builds with:

• Android Studio 3.1 (https://developer.android.com/studio/archive)
• Android SDK Build Tools v27.0.3
• gradle 4.4 (as defined in https://github.com/OB1Company/native-bazaar/blob/develop/android/gradle/wrapper/gradle-wrapper.properties)
• Java 1.8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

Using gradle to run app on-device

From the repository root, perform the following steps:

1. Ensure your device is available

$ adb devices
List of devices attached
8AAX0P48U       device

2. cd ./android
3. ./gradlew clean
4. ./gradlew installRelease
5. Find the application installed on your device.

Contribution recommendations

Further development of Haven will be primarily sourced from community contributions. Below are some recommended entry points for contributors:

• More consistent 'basic' modularisation (e.g. add all the repetitive colors to commonColors.js
• Component modularisation to make code DRY
• Improve the folder structure, the module structure, and naming to have them make more sense (e.g. components are sometimes not put correctly to the sub-section of the Atomic Design)
• Upgrade modules to be up-to-date (e.g, react-navigation should be upgraded from 3 to 5)
• Will need to gradually transition to Functional Component leveraging React Hook
• Renaming price conversion functions (e.g. minUnitAmountToBCH) to something more generic

Unit testing

Some high priority targets for developing unit tests:

• Checkout flow, specifically the price calculation
• All the components that include prices
• The Order details screen for various order statuses

End-to-end testing

Integration of an end-to-end testing tool such as Appium should be considered and applied to:

• The checkout flow
• The order flow for the various order statuses
• The send money flow
• The deep linking flow (just to make sure the various kinds of deep links open correct screens)

Troubleshooting

./gradlew clean produces java.lang.NullPointerException

> Configure project :react-native-webview
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':react-native-webview'.
> java.lang.NullPointerException (no error message)

This typically occurs when the wrong Java version is used. The expected version for Java is 1.8. See this StackOverflow question for help switching to 1.8.

Missing modules

If you get an error like this:

While resolving module `react-native-vector-icons/Ionicons`, the Haste package `react-native-vector-icons` was found. However the module `Ionicons` could not be found within the package.

Type into the terminal: rm ./node_modules/react-native/local-cli/core/__fixtures__/files/package.json
