High-performance 2d Graphics for React Native using Skia
Checkout the full documentation here.
React Native Skia brings the Skia Graphics Library to React Native. Skia serves as the graphics engine for Google Chrome and Chrome OS, Android, Flutter, Mozilla Firefox and Firefox OS, and many other products.
To develop react-native-skia, you need to build the skia libraries on your computer.
Make sure to check out the sub modules:
git submodule update --init --recursive
You also need to install some tools for the build scripts to work. Run yarn in the root of the project to install them.
Make sure you have all the tools required for building the skia libraries (XCode, Ninja, CMake, Android NDK / build tools).
On MacOS you can install Ninja via homebrew:
brew install ninjaIf you have Android Studio installed, make sure $ANDROID_NDK is available.
ANDROID_NDK=/Users/username/Library/Android/sdk/ndk/<version> for instance.
If the NDK is not installed, you can install it via Android Studio by going to the menu File > Project Structure.
And then the SDK Location section. It will show you the NDK path, or the option to Download it if you don't have it installed.
- Install dependencies
yarn bootstrap - Build the Skia libraries with
yarn build-skia(this can take a while) - Copy Skia headers
yarn copy-skia-headers - Run
pod installin the example project
If a new version of Skia is included in an upgrade of this library, you need to perform a few extra steps before continuing:
- Update submodules:
git submodule update --recursive --remote - Clean Skia:
yarn clean-skia - Build Skia:
yarn build-skia - Copy Skia Headers:
yarn copy-skia-headers - Run pod install in the example project
- Run the commands in the Building section
- Build the Android binaries with
yarn build-skia-android - Build the NPM package with
yarn build-npm
Publish the NPM package manually. The output is found in the dist folder.
- Install Cocoapods in the example/ios folder
cd example/ios && pod install && cd ..
