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<ReactPackage> 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 <appName> -k" to retrieve your key. return Arrays.<ReactPackage>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
<key>CodePushDeploymentKey</key>
<string>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)</string>
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);

}
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
