react

1.全局安装脚手架（code-push-cli）如果已经安装过，不需要重复安装

1.npm install -g code-push-cli
2.code-push -v 查看版本

2. 创建一个code-push 账号

code-push register
会打开页面进行注册

3.注册完成后 记住页面显示的key 复制此key到终端里面完成注册

4. 创建一个名称为 rn6 的项目

code-push app add rn6 android react-native
创建之后会返回一个key（正式签名的key）


到 https://appcenter.ms/apps (可以查看)

5 cd 到 rn6 添加依赖

yarn add react-native-code-push

6.like到项目（增加原生项目的依赖）

react-native link react-native-code-push	
这里需要第4步的key

7.建议此时可以打包生成apk，来测试一下打包，（发生过配置完成后，打包失败的情况）具体打包流程，参考

https://www.cnblogs.com/shaoting/p/7117454.html

8.修改android的配置（第6步执行完事后，这些配置已经配置完成了，只是检查一遍，如果没有配置成功，按照下面的方法进行配置）

（1）在 android/app/build.gradle文件里面增加了如下代码：

	apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"		

...
dependencies {
...
    implementation project(':react-native-code-push')
 ...
}
...

（2）在/android/settings.gradle中添加如下代码:

include ':react-native-code-push'
project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')

（3）在/android/app/src/main/java/com/项目名称/MainApplication.java中添加如下代码:

...
import com.microsoft.codepush.react.CodePush;
...
 @Override
        protected String getJSBundleFile() {
            return CodePush.getJSBundleFile();
        }
...
   @Override
        protected List<ReactPackage> getPackages() {
            return Arrays.<ReactPackage>asList(
               ...
                new CodePush(getResources().getString(R.string.reactNativeCodePush_androidDeploymentKey), getApplicationContext(), BuildConfig.DEBUG)
            );
        }
...

（4）在 android/app/build.gradle中有个 android.defaultConfig.versionName属性，必须改成3段（默认是2段的）

android{ 
  ...
  defaultConfig{ 
     versionName "0.0.1" 
  }
  ...
}

9在 App.js 中加入热更新代码

import React, { Component } from 'react';
import {
  AppRegistry,
  Dimensions,
  Image,
  StyleSheet,
  Text,
  TouchableOpacity,
  View,
} from 'react-native';
import CodePush from "react-native-code-push";
class App extends Component<{}> {
  constructor() {
    super();
    this.state = { restartAllowed: true };
  }
  codePushStatusDidChange(syncStatus) {
    switch(syncStatus) {
      case CodePush.SyncStatus.CHECKING_FOR_UPDATE:
        this.setState({ syncMessage: "Checking for update." });
        break;
      case CodePush.SyncStatus.DOWNLOADING_PACKAGE:
        this.setState({ syncMessage: "Downloading package." });
        break;
      case CodePush.SyncStatus.AWAITING_USER_ACTION:
        this.setState({ syncMessage: "Awaiting user action." });
        break;
      case CodePush.SyncStatus.INSTALLING_UPDATE:
        this.setState({ syncMessage: "Installing update." });
        break;
      case CodePush.SyncStatus.UP_TO_DATE:
        this.setState({ syncMessage: "App up to date.", progress: false });
        break;
      case CodePush.SyncStatus.UPDATE_IGNORED:
        this.setState({ syncMessage: "Update cancelled by user.", progress: false });
        break;
      case CodePush.SyncStatus.UPDATE_INSTALLED:
        this.setState({ syncMessage: "Update installed and will be applied on restart.", progress: false });
        break;
      case CodePush.SyncStatus.UNKNOWN_ERROR:
        this.setState({ syncMessage: "An unknown error occurred.", progress: false });
        break;
    }
  }
  codePushDownloadDidProgress(progress) {
    this.setState({ progress });
  }
  toggleAllowRestart() {
    this.state.restartAllowed
      ? CodePush.disallowRestart()
      : CodePush.allowRestart();
    this.setState({ restartAllowed: !this.state.restartAllowed });
  }
  getUpdateMetadata() {
    CodePush.getUpdateMetadata(CodePush.UpdateState.RUNNING)
      .then((metadata: LocalPackage) => {
        this.setState({ syncMessage: metadata ? JSON.stringify(metadata) : "Running binary version", progress: false });
      }, (error: any) => {
        this.setState({ syncMessage: "Error: " + error, progress: false });
      });
  }
  /** Update is downloaded silently, and applied on restart (recommended) */
  sync() {
    CodePush.sync(
      {},
      this.codePushStatusDidChange.bind(this),
      this.codePushDownloadDidProgress.bind(this)
    );
  }
  /** Update pops a confirmation dialog, and then immediately reboots the app */
  syncImmediate() {
    CodePush.sync(
      { installMode: CodePush.InstallMode.IMMEDIATE, updateDialog: true },
      this.codePushStatusDidChange.bind(this),
      this.codePushDownloadDidProgress.bind(this)
    );
  }
render() {
    let progressView;
    if (this.state.progress) {
      progressView = (
        <Text style={styles.messages}>{this.state.progress.receivedBytes} of {this.state.progress.totalBytes} bytes received</Text>
      );
    }
    return (
      <View style={styles.container}>
        <Text>1.0.0</Text>
        <Text style={styles.welcome}>
          Welcome to CodePush!

        {progressView}
        {/* <Image style={styles.image} resizeMode={"contain"} source={require("./images/laptop_phone_howitworks.png")}/> */}
        <TouchableOpacity onPress={this.toggleAllowRestart.bind(this)}>

        </TouchableOpacity>
        <TouchableOpacity onPress={this.getUpdateMetadata.bind(this)}>

        </TouchableOpacity>
        <Text style={styles.messages}>{this.state.syncMessage || ""}</Text>
      </View>
    );
  }
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: "center",
    backgroundColor: "#F5FCFF",
    paddingTop: 50
  },
  image: {
    margin: 30,
    width: Dimensions.get("window").width - 100,
    height: 365 * (Dimensions.get("window").width - 100) / 651,

  messages: {
    marginTop: 30,
    textAlign: "center",

  },
});
/**
 * Configured with a MANUAL check frequency for easy testing. For production apps, it is recommended to configure a
 * different check frequency, such as ON_APP_START, for a 'hands-off' approach where CodePush.sync() does not
 * need to be explicitly called. All options of CodePush.sync() are also available in this decorator.
 */
let codePushOptions = { checkFrequency: CodePush.CheckFrequency.MANUAL };
App = CodePush(codePushOptions)(App);
export default App;

10 打包-安装程序到手机

11 修改app.js 内容来测试热更新（保存后发布更新）

code-push release-react rn6 android --t 1.0.0 --m true --d Production
