React Native 资源包拆分实战分析

// 安卓端代码示例 - 加载公共基础包
ReactNativeHost RNHost = new ReactNativeHost(application) {
  @Nullable 
  @Override 
  protected String getBundleAssetName() {
    return "Assets目录下的common.android.bundle路径";
  }
  @Nullable 
  @Override 
  protected String getJSBundleFile() {
    return "本地磁盘中的common.android.bundle路径";
  }
}
ReactInstanceManager bridge = RNHost.getReactInstanceManager();
if (!bridge.hasStartedCreatingInitialContext()) {
  bridge.createReactContextInBackground();
}

// 安卓端代码示例 - 加载业务包
ReactContext context = RNHost.getReactInstanceManager().getCurrentReactContext();
CatalystInstance catalyst = context.getCatalystInstance();
String fileName = "本地业务包business.android.bundle路径"
catalyst.loadScriptFromFile(fileName, fileName, false);

// iOS端代码示例 - 加载公共基础包
NSURL *commonBundleURL = [[NSBundle mainBundle] URLForResource:@"common" withExtension:@"ios.bundle"];//公共基础包路径
RCTBridge *bridge = [[RCTBridge alloc] initWithBundleURL:commonBundleURL moduleProvider:nil launchOptions:launchOptions];

// iOS端代码示例 - Category暴露私有方法
@interface RCTBridge (MyCustomerBridge)   
 - (void)executeSourceCode:(NSData *)sourceCode sync:(BOOL)sync;
@end
// iOS端代码示例 - 加载业务包
NSURL *businessBundleURL = [[NSBundle mainBundle] URLForResource:@"business" withExtension:@"ios.bundle"];//业务包路径
NSError *error = nil;
NSData *sourceData = [NSData dataWithContentsOfURL:businessBundleURL options:NSDataReadingMappedIfSafe error:&error];
if (error) { 
  return 
}
[bridge.batchedBridge executeSourceCode:sourceData sync:NO];
