react-native 热更新实践

配置appcenter
一、安装appcenter
npm install -g appcenter-cli
/** 安装完成后 */
appcenter help
/** 如果出现帮助指令说明安装成功 */
二、appcenter login
在控制台执行
appcenter login
执行后在打开的浏览器选择一种登陆方式登陆(打开的网页需要挂代理)
登陆成功后会获得token,将token 填入控制台完成登陆。
登陆成功后
执行
appcenter profile list
查看登陆信息是否正确。
三、在appcenter 上创建不同平台的app
appcenter apps create -d <appDisplayName> -o <operatingSystem> -p <platform>
只考虑ios 和android
appcenter apps create -d RNDemoAndroid -o Android -p React-Native
appcenter apps create -d RNDemoiOS -o iOS -p React-Native
创建app在Staging和Production环境的部署key
//ios
appcenter codepush deployment add -a <ownerName>/RNDemoiOS Staging
appcenter codepush deployment add -a <ownerName>/RNDemoiOS Production
//android
appcenter codepush deployment add -a <ownerName>/RNDemoAndroid Staging
appcenter codepush deployment add -a <ownerName>/RNDemoAndroid Production
以上shell命令都会返回成功的提示
执行一下语句
//自行替换
ownername appName appcenter codepush deployment list -a <ownerName>/<appName> -k
到这里appcenter 配置过程完成
4、出现的问题以及踩的坑
- appcenter login 的网页需要挂代理
- 在appcenter.ms/apps 网站上没找到地方看上传的包以及部署分支,不知道是不是姿势不对

安装 react-native-code-push 及配置
一、安装
执行
yarn add react-native-code-push cd ios && pod install
二、React Native 0.60及以上版本插件安装配置(iOS)
此处只针对react-native 0.60 版本及以上配置
- 确保已安装必须的CocoaPods依赖项
- 打开AppDelegate.m文件,并为 CodePush 标头添加导入语句:
#import <CodePush/CodePush.h>
AppDelegate.m (注意:#import 必须在FB_SONARKIT_ENABLED 前面,否则ios archive 会报错)
#import "AppDelegate.h"
#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
//** 引入热更新
#import <CodePush/CodePush.h>
#ifdef FB_SONARKIT_ENABLED
#import <FlipperKit/FlipperClient.h>
#import <FlipperKitLayoutPlugin/FlipperKitLayoutPlugin.h>
#import <FlipperKitUserDefaultsPlugin/FKUserDefaultsPlugin.h>
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>
#import <SKIOSNetworkPlugin/SKIOSNetworkAdapter.h>
#import <FlipperKitReactPlugin/FlipperKitReactPlugin.h>
- 找到这一行
return [[NSBundle mainBundle] URLForResource:@"main" withExtension:@"jsbundle"];
- 替换为
return [CodePush bundleURL];
- 增加部署的key值到 info.plist中。key值详见上方1.3
<key>CodePushDeploymentKey</key>
<string>xxx</string>
到这里ios就配置完成了
更多的内容以及配置react-native 版本0.6以下的详见
三、React Native 0.60及以上版本插件安装配置(Android)
- 在android/settings.gradle的结尾插入
...
include ':app', ':react-native-code-push'
project(':react-native-code-push').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-code-push/android/app')
- 在你的android/app/build.gradle中
...
apply from: "../../node_modules/react-native/react.gradle"
//添加这一行 apply
from: "../../node_modules/react-native-code-push/android/codepush.gradle"
...
- 通过以下更改,更新MainApplication.java文件以使用 CodePush:
...
// 1. Import the plugin class.
import com.microsoft.codepush.react.CodePush;
public class MainApplication extends Application implements ReactApplication {
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();
}
};
}
- 将部署的key加入到strings.xml
<resources>
<string name="app_name">AppName</string>
//xxx 是部署的key
<string moduleConfig="true" name="CodePushDeploymentKey">xxx</string>
</resources>
到这里安卓配置就完成了
更多的配置
四、遇到的问题以及踩的坑
- xcode 运行项目到模拟器的时候报错
Could not build module 'Foundation'
解决方案: 更新mac系统到最新,更新xcode版本到最新
- xcode archive 项目打包时提示:
use of undeclared identifier 'CodePush'
解决方案:#import 必须在FB_SONARKIT_ENABLED 前面,否则ios archive 会报错
react-native 项目代码
一、react-native codepush 使用
直接包裹住根组件,自动检查更新
//for class
import codePush from "react-native-code-push";
class MyApp extends Component { }
MyApp = codePush(MyApp);
//for hook
import codePush from "react-native-code-push";
const MyAp = () => { }
// 如果需要更快更新,可以将 MyApp = codePush(MyApp) 添加;
// let codePushOptions = { checkFrequency: codePush.CheckFrequency.ON_APP_RESUME };
// MyApp = codePush(codePushOptions)(MyApp);
MyApp = codePush(MyApp);
如果需要手动检查更新
let codePushOptions = { checkFrequency: codePush.CheckFrequency.MANUAL };
class MyApp extends Component {
onButtonPress() {
codePush.sync({
updateDialog: true,
installMode: codePush.InstallMode.IMMEDIATE
});
}
render() {
return (
<View>
<TouchableOpacity onPress={this.onButtonPress}>
<Text>Check for updates</Text>
</TouchableOpacity>
</View>
)
}
}
MyApp = codePush(codePushOptions)(MyApp);
二、快速验证代码
替换app.tsx 为以下代码,可以快速验证热更新效果
/* eslint-disable no-lone-blocks */
/* eslint-disable react-native/no-inline-styles */
import React from 'react';
import type {Node} from 'react';
import {
SafeAreaView,
Text,
Alert,
useColorScheme,
TouchableOpacity,
View,
Image,
} from 'react-native';
import testImg from './assets/test.png';
import Video from 'react-native-video';
import CodePush from 'react-native-code-push';
import consultant from './assets/video/consultant.mp4';
const App: () => Node = () => {
const backgroundStyle = {
backgroundColor: '#fff',
flex: 1,
};
const check = () => {
CodePush.sync(
{
installMode: CodePush.InstallMode.IMMEDIATE,
},
(status: CodePush.SyncStatus) => {
console.log(status, CodePush.SyncStatus);
switch (status) {
case CodePush.SyncStatus.UP_TO_DATE:
{
Alert.alert('已经是最新版本');
}
break;
case CodePush.SyncStatus.DOWNLOADING_PACKAGE:
{
Alert.alert('正在下载更新包');
}
break;
case CodePush.SyncStatus.UPDATE_INSTALLED:
{
Alert.alert('最新版本已安装');
}
break;
case CodePush.SyncStatus.UPDATE_IGNORED:
{
Alert.alert('更新已忽略');
}
break;
case CodePush.SyncStatus.CHECKING_FOR_UPDATE:
{
Alert.alert('正在检查更新');
}
break;
default:
break;
}
console.log(status);
},
() => {},
);
};
const clear = () => {
CodePush.clearUpdates();
};
return (
<SafeAreaView style={backgroundStyle}>
<View style={{flex: 1, alignItems: 'center', justifyContent: 'center'}}>
<TouchableOpacity onPress={check}>
<Text>Check for updates</Text>
</TouchableOpacity>
<Text>当前版本1.1.1</Text>
<TouchableOpacity onPress={clear} style={{marginTop: 20}}>
<Text>clear updates</Text>
</TouchableOpacity>
{/** 校验图片 */}
{/* <Image source={testImg} style={{width: 100, height: 100}} /> */}
{/** 验证视频 */}
{/* <Video
source={consultant}
resizeMode="cover"
paused={false}
repeat
style={{width: 200, height: 200}}
/> */}
</View>
</SafeAreaView>
);
};
export default CodePush(App);
三、遇到的问题以及踩到的坑
- 在react-native-cli 初始化时,抛出错误
cli.init(root, projectName);
原因是0.7以上版本的react-native 不支持 基于react-native-cli创建
于是锁定到目前用的版本 0.67.5
npx react-native init demoOnline --template react-native-template-typescript --version 0.67.5
创建成功
推送更新
一、上传你的jsbudle包到codepush,发布更新
appcenter codepush release-react -a <ownerName>/<appName>
//example
appcenter codepush release-react -a <ownerName>/MyApp-iOS
appcenter codepush release-react -a <ownerName>/MyApp-Android
发布成功会提示
此时你就可以测试一下热更新问题
二、遇到的问题以及踩到的坑
- codepush 推送jsbudle 错误
appcenter codepush release-react -a 1256003290-qq.com/RNDemoIOS --plist-file-prefix "ios/orange"
/**error message */
/**Command 'codepush release-react -a 1256003290-qq.com/RNDemoIOS' failed with exception "Unable to find either of the following plist files in order to infer your app's binary version: "ios/reactnativecli/Info.plist", "ios/Info.plist". If your plist has a different name, or is located in a different directory, consider using either the "--plist-file" or "--plist-file-prefix" parameters to help inform the CLI how to find it." */
appcenter codepush release-react -a 1256003290-qq.com/RNDemoIOS
/** Command 'codepush release-react -a 1256003290-qq.com/RNDemoIOS' failed with exception "Unable to find either of the following plist files in order to infer your app's binary version: "ios/reactnativecli/Info.plist", "ios/Info.plist".

appcenter codepush release-react -a 1256003290-qq.com/RNDemoIOS -p"ios/orange/info.plist"
/** Command 'codepush release-react -a 1256003290-qq.com/RNDemoIOS -p ios/orange/info.plist' failed with exception "Unable to find either of the following pbxproj files in order to infer your app's binary version: "ios/reactnativecli.xcodeproj/project.pbxproj", "ios/project.pbxproj"."*/
发现怎么执行,codepush 都表示路径不对,找不到info.plist。最后发现codepush 去的包名是从package.json的name,他会按照这个去找路径下的配置文件,我的包名恰好和项目名不一致,导致了问题
解决方案:修改package包名和项目名一致
实际使用效果
一、效果
效果如图,图片资源和视频资源也测试过,完全没有问题
