RN热更新——codepush

一、安装注册code-push

1.安装code-push
$ npm install -g code-push-cli
2.注册账号
$ code-push register

这时候会自动启动浏览器打开网页并提供一个codePush AccessKey,然后命令行里出现需要输入access key

Enter your access key:

输入access key�登录

3.添加一个CodePush应用(myProject是应用名字)
$ code-push app add �myProject

出现

||     name    || Deployment Key ||
|| Production  || (一串37位的key) ||
|| Staging     || (一串37位的key) ||

如上有两个发布键值。一个Production是对应生产环境的,二Staging是对应开发环境的。当然我们还可以添加其他的发布键值。
这个值在后面我们集成工程里面要用到。

二、react-native应用接入code-push

1.安装react-native-code-push

在项目根目录运行

$ npm install react-native-code-push --save
2.cocoapods导入code-push
  • ios

修改Podfile文件,添加:

  pod 'CodePush', :path => './node_modules/react-native-code-push'

运行

  $ pod install
  • android

  • RNPM
    安装 RNPM(依次运行)
    如果 React Native 版本 >= 0.27 (因为 rnpm link 已经被合并到React Native CLI)

     $ react-native link react-native-code-push
    

否则
$ npm i -g rnpm
$ rnpm link react-native-code-push

  • 手动
    在android/settings.gradle文件里添加
    include ':app'
    include ':react-native-code-push'
    project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')
    在android/app/build.gradle文件里添加
    dependencies {
    ...
    compile project(':react-native-code-push')
    }
    在android/app/build.gradle文件里添加
    ...
    apply from: "../../node_modules/react-native/react.gradle"
    apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"
    ...
    修改MainApplication.java文件
    ...
    // 1. Import the plugin class.
    import com.microsoft.codepush.react.CodePush;

     // public class MainActivity extends ReactActivity {                                     // For React Native v0.19 - v0.28
     public class MainApplication extends Application implements ReactApplication {        // For React Native >= 0.29
    
         private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {
             ...
             // 2. Override the getJSBundleFile method in order to let
             // the CodePush runtime determine where to get the JS
             // bundle location from on each app start
             @Override protected String getJSBundleFile() {
                 return CodePush.getJSBundleFile();
             }
    
             @Override protected List getPackages() {
                 // 3. Instantiate an instance of the CodePush runtime and add it to the list of
                 // existing packages, specifying the right deployment key. If you don't already
                 // have it, you can run "code-push deployment ls  -k" to retrieve your key.
                 return Arrays.asList(
                     new MainReactPackage(),
                     new CodePush("deployment-key-here", MainApplication.this, BuildConfig.DEBUG)
                 );
             }
         };
     }
    

在android/app/build.gradle文件中(应用版本codepush需要三位数)
android{
defaultConfig{
versionName "1.0.0"
}
}
Background React Instances
This section is only necessary if you're explicitly launching a React Native instance without an Activity
(for example, from within a native push notification receiver). For these situations, CodePush must be told how to find your React Native instance.*
In order to update/restart your React Native instance, CodePush must be configured with a ReactInstanceHolder
before attempting to restart an instance in the background. This is usually done in your Application
implementation.
修改MainApplication.java文件
// For React Native >= v0.29
...
// 1. Declare your ReactNativeHost to extend ReactInstanceHolder.
// ReactInstanceHolder is a subset of ReactNativeHost, so no additional implementation is needed.
import com.microsoft.codepush.react.ReactInstanceHolder;
public class MyReactNativeHost extends ReactNativeHost implements ReactInstanceHolder {
// ... usual overrides
}
// 2. Provide your ReactNativeHost to CodePush.
public class MainApplication extends Application implements ReactApplication {

        private final MyReactNativeHost mReactNativeHost = new MyReactNativeHost(this);

        @Override public void onCreate() {
            CodePush.setReactInstanceHolder(mReactNativeHost);
            super.onCreate();
        }
    }

    // For React Native v0.19 - v0.28
    // 1. Provide your ReactNativeHost to CodePush.
    public class MainApplication extends Application {
        // ... initialize your instance holder
        @Override public void onCreate() {
            CodePush.setReactInstanceHolder(mReactNativeHost);
            super.onCreate();
        }
    }

以上的操作,即可成功集成CodePush。

3.配置相关文件
  • IOS
1.修改js程序入口文件

RN应用是appDelegate.m
原生应用是ReactView.m

  #ifdef DEBUG
      jsCodeLocation = [NSURL URLWithString:@"http://192.168.1.103:8081/index.ios.bundle?platform=ios"];
  #else
      jsCodeLocation = [CodePush bundleURLForResource:@"index"];
  #endif
2.修改info.plist文件
  CodePushDeploymentKey
  前面添加应用得到的发布key(注意这里要选择是正式版的key还是测试版的key,不是发布到appstore可以用Staging的key)

命令行里面输入

$ code-push

可以看到code-push各个命令

三、更新策略(js)

1、导入react-native-code-push

import codePush from "react-native-code-push";

2、策略

默认情况下,CodePush会在app每次启动的时候去检测是否有更新,如果有,app会自动下载并在下次打开app时安装

class MyApp extends Component {}
MyApp = codePush(MyApp);

// For ES7
import codePush from "react-native-code-push";

@codePush
class MyApp extends Component {}

每次打开app时检测更新并下载,下次打开app时安装

// Sync for updates everytime the app resumes.
class MyApp extends Component {}
MyApp = codePush({
    checkFrequency: codePush.CheckFrequency.ON_APP_RESUME,
    installMode: codePush.InstallMode.ON_NEXT_RESUME
})(MyApp);

实时检测更新并下载,下载完成后立即安装

// Active update, which lets the end user know
// about each update, and displays it to them
// immediately after downloading it
class MyApp extends Component {}
MyApp = codePush({
    updateDialog: true,
    installMode: codePush.InstallMode.IMMEDIATE
})(MyApp);

记录app检测、下载、安装的状态(可以实现进度条当做友好提示)

// Make use of the event hooks to keep track of
// the different stages of the sync process.
class MyApp extends Component {
    codePushStatusDidChange(status) {
        switch(status) {
            case codePush.SyncStatus.CHECKING_FOR_UPDATE:
                console.log("Checking for updates.");
                break;
            case codePush.SyncStatus.DOWNLOADING_PACKAGE:
                console.log("Downloading package.");
                break;
            case codePush.SyncStatus.INSTALLING_UPDATE:
                console.log("Installing update.");
                break;
            case codePush.SyncStatus.UP_TO_DATE:
                console.log("Installing update.");
                break;
            case codePush.SyncStatus.UPDATE_INSTALLED:
                console.log("Update installed.");
                break;
        }
    }
    codePushDownloadDidProgress(progress) {
        console.log(progress.receivedBytes + " of " + progress.totalBytes + " received.");
    }
}
MyApp = codePush(MyApp);

disallowRestart/allowRestart

class OnboardingProcess extends Component {
  ...
  componentWillMount() {
    // Ensure that any CodePush updates which are
    // synchronized in the background can't trigger
    // a restart while this component is mounted. codePush.disallowRestart();
  }
  componentWillUnmount() {
    // Reallow restarts, and optionally trigger
    // a restart if one was currently pending.
    codePush.allowRestart();
  }
  ...
}

四、发布版本

1、打包
$ code-push release myProject ./bundle/index.jsbundle 1.20.1 --mandatory true

myProject代表我们要更新的项目名称,就是前面我们注册的index.jsbundle是我们要更新的内容,1.20.1是我们在appstore发布的版本号,注意这个地方是我们程序二进制文件的版本号,其实这句命令就是:更新myProject 1.20.1的版本二进制文件,只有1.20.1的版本才能收到更新。最后面的参数是是否强制更新。这段命令没有指定更新的环境是正式环境还是测试环境,默认的是测试环境,如果要发布到正式环境需要指定一下

 code-push release wanna ./bundle/index.jsbundle 1.20.1 -d "Production" --mandatory true。 

后面还可以在后面添加参数比如1.20.1版本的多少用户可以更新–rollout 20,代表百分之20的myProject 1.20.1的用户可以收到这个更新

2、修改发布后版本的参数

比如上面,我们发布更新到了1.20.1的测试版本,更新百分之20的用户,可是我们发布完成之后,想更新百分之30的用户:

$ code-push patch wanna 1.20.1 --rollout 20

code-push for redux -- react-native-code-push-saga

注意:

  • 苹果不允许应用内有弹框提示更新
