手动集成

>= RN 0.60.x

iOS

1. cd ios && pod install && cd ..

2. AppDelegate.m文件，引入头文件#import "HotUpdate.h"

3. AppDelegate.m文件，didFinishLaunchingWithOptions生命周期函数中将

   return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];

   替换成

   return [HotUpdate bundleURL];

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java
   • Add import com.rickl.reactlibrary.hotupdate.HotUpdate; to the imports at the top of the file
   • 在getPackages()函数同层级下，增加下面方法

       @Override
       protected String getJSBundleFile() {
       	return HotUpdate.getJSBundleFile();
       }

<= RN 0.59.x

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]

2. Go to node_modules ➜ react-native-hot-update and add HotUpdate.xcodeproj

3. In XCode, in the project navigator, select your project. Add libHotUpdate.a to your project's Build Phases ➜ Link Binary With Libraries

4. AppDelegate.m文件，引入头文件#import <HotUpdate/HotUpdate.h>

5. AppDelegate.m文件，didFinishLaunchingWithOptions生命周期函数中将

   jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];

   替换成

   jsCodeLocation = [HotUpdate bundleURL];

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import com.rickl.reactlibrary.hotupdate.HotUpdate; to the imports at the top of the file

• Add new HotUpdate(getApplicationContext(), BuildConfig.DEBUG) to the list returned by the getPackages() method

• 在getPackages()函数同层级下，增加下面方法

    @Override
    protected String getJSBundleFile() {
    	return HotUpdate.getJSBundleFile();
    }

2. Append the following lines to android/settings.gradle:

   include ':react-native-hot-update'
   project(':react-native-hot-update').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-hot-update/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-hot-update')
   

Usage

import HotUpdate from 'react-native-hot-update';

class App extends React.Component {
	componentDidMount() {
		HotUpdate.setServerUrl(`http://xxx.com/project/hotupdate/${Platform.OS}`)
		HotUpdate.notifyAppReady()
	}

	render() {
		return (
			<View>
				<Button title="checkUpdate" onPress={this.checkUpdate} />
			</View>
		)
	}

	checkUpdate = () => {
		    let remotePackage = await HotUpdate.checkUpdate()
    if (remotePackage) {
      Alert.alert(
        '更新提示',
        remotePackage.description,
        [
          { text: '取消' },
          { 
            text: '更新', 
            onPress: () => {
              HotUpdate.download(remotePackage, ({totalBytes, receivedBytes}) => {
                this.setState({ progress: `${receivedBytes} / ${totalBytes}` })
              }).then(() => {
                Alert.alert('下载完成', '马上重启?',
                  [
                    { 
                      text: '稍后',
                      onPress: () => { HotUpdate.install(remotePackage, HotUpdate.InstallMode.ON_NEXT_RESUME) }
                    },
                    {
                      text: '现在',
                      onPress: () => { HotUpdate.install(remotePackage, HotUpdate.InstallMode.IMMEDIATE) }
                    }
                  ]
                )
              }).catch((e) => {
                alert('下载失败： ' + e.toString())
              })
            },
          },
        ]
      )
    } else {
      alert('暂无更新')
    }
	}
}

HotUpdate;
