react-native-piratechain

This library packages the PiratechainLightClientKit for use on React Native.

Usage

First, add this library to your React Native app using NPM or Yarn, and run pod install as necessary to integrate it with your app's native code.

If you encounter errors during pod install, you may need to add the following code to the target section of your Podfile:

# Piratechain transitive dependencies:
pod 'CGRPCZlib', :modular_headers => true
pod 'CNIOAtomics', :modular_headers => true
pod 'CNIOBoringSSL', :modular_headers => true
pod 'CNIOBoringSSLShims', :modular_headers => true
pod 'CNIODarwin', :modular_headers => true
pod 'CNIOHTTPParser', :modular_headers => true
pod 'CNIOLinux', :modular_headers => true
pod 'CNIOWindows', :modular_headers => true
pod 'sqlite3', :modular_headers => true

On the Android side, you may need to configure an explicit Kotlin version, so all your native dependencies will be compatible with one another. Simply define kotlinVersion in your android/build.gradle file:

buildscript {
  ext {
    kotlinVersion = '1.8.22'
  }
}

API overview

  • Tools
    • deriveViewingKey
    • getBirthdayHeight
    • isValidAddress
  • makeSynchronizer
    • start
    • stop
    • rescan
    • getLatestNetworkHeight
    • getBalance
    • getTransactions
    • sendToAddress
    • deriveUnifiedAddress

Tools contains methods that don't require a running synchronizer (with one exception, isValidAddress on Android which does requires any synchronizer connected to the requested network).

Developing

This library relies on a large amount of native code from other repos. To integrate this code, you must run the following script before publishing this library to NPM:

npm run update-sources

This script will download PiratechainLightClientKit and piratechain-light-client-ffi, modify them for React Native, and integrate them with our wrapper code.

The update-sources script is also the place to make edits when upgrading any of the third-party dependencies.

We also have an update-checkpoints command that will connect to a node and generate fresh checkpoints based on the chain state.

Source Formatting

Install ktlint and swift-format using your package manager, such as brew install ktlint swift-format. Run fix-swift or fix-kotlin to format the native sources.
