Getting started

Preparing environment

For macOS developers:

1. Xcode with iOS sdk: build the iOS app.
2. Android Studio with NDK: build the android app.
3. Node.JS: run the build scripts.

homebrew is recommended to install the dependencies.

For Windows developers:

1. Android Studio with NDK: build the android app.
2. Node.JS: run the build scripts.

Windows can't run the iOS development environment so far.

Build your first Hippy app

Start the iOS simulator with hippy-react or hippy-vue demo

For iOS we recommend to use iOS simulator when first try, however, you may change the Xcode configuration to install the app to iPhone if you are a iOS expert.

1. Install the dependencies with npm install.
2. Build the front-end sdk packages with npm run build.
3. Choose a demo to build with npm run buildexample -- [hippy-react-demo|hippy-vue-demo].
4. Start the Xcode and build the iOS app with open examples/ios-demo/HippyDemo.xcodeproj.

Start the android app with hippy-react or hippy-vue demo

For Android we recommend to use the real cellphone for better experience, because Hippy is using X5 JS engine which can't support x86 simulator, as well as ARM simulator has a low performance.

Before build the android app, please make sure the SDK and NDK is installed, And DO NOT update the build toolchain.

1. Install the dependencies with npm install.
2. Build the front-end sdk packages with npm run build.
3. Open a terminal, then build the hippy-react demo with npm run buildexample -- hippy-react-demo, or build the hippy-vue demo with npm run buildexample -- hippy-vue-demo .
4. Open the examples/android-demo with Android Studio.
5. Connect android phone with USB cable and make sure USB debugging mode and USB installation are enabled.
6. Open the project with Android Studio, run and install the apk.

If you encounter the issue of No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android, here is the solution.
