此文使用当下最新版本的RN与Code-Push进行演示，其中的参数不会过多进行详细解释，更多参数解释可参考其它文章，这里只保证APP能正常进行热更新操作，方便快速入门，开始来快活吧。

操作指南

以下操作在Mac系统上完成
项目地扯https://github.com/dounine/dounineApp
Branches:3分钟完成React-Native热更新

1. 创建React-Native项目

react-native init dounineApp

2. 安装code-push-cli

npm install -g code-push-cli

3. 注册code-push帐号

code-push register
Please login to Mobile Center in the browser window we've just opened.

Enter your token from the browser: 
#会弹出一个浏览器,让你注册,可以使用github帐号对其进行授权,授权成功会给一串Token,点击复制，在控制进行粘贴回车(或者使用code-push login命令)。

Enter your token from the browser:  b0c9ba1f91dd232xxxxxxxxxxxxxxxxx
#成功提示如下方
Successfully logged-in. Your session file was written to /Users/huanghuanlai/.code-push.config. You can run the code-push logout command at any time to delete this file and terminate your session.

4. 在code-push添加一个ios的app

code-push app add dounineApp-ios ios react-native
#成功提示如下方
Successfully added the "dounineApp-ios" app,along with the following default deployments:
┌────────────┬──────────────────────────────────────────────────────────────────┐
│ Name       │ Deployment Key                                                   │
├────────────┼──────────────────────────────────────────────────────────────────┤
│ Production │ yMAPMAjXpfXoTfxCd0Su9c4-U4lU6dec4087-57cf-4c9d-b0dc-ad38ce431e1d │
├────────────┼──────────────────────────────────────────────────────────────────┤
│ Staging    │ IjC3_iRGEZE8-9ikmBZ4ITJTz9wn6dec4087-57cf-4c9d-b0dc-ad38ce431e1d │
└────────────┴──────────────────────────────────────────────────────────────────┘

5. 继续在code-push添加一个android的app

code-push app add dounineApp-android android react-native
#成功提示如下方
Successfully added the "dounineApp-android" app,along with the following default deployments:
┌────────────┬──────────────────────────────────────────────────────────────────┐
│ Name       │ Deployment Key                                                   │
├────────────┼──────────────────────────────────────────────────────────────────┤
│ Production │ PZVCGLlVW-0FtdoCF-3ZDWLcX58L6dec4087-57cf-4c9d-b0dc-ad38ce431e1d │
├────────────┼──────────────────────────────────────────────────────────────────┤
│ Staging    │ T0NshYi9X8nRkIe_cIRZGbAut90a6dec4087-57cf-4c9d-b0dc-ad38ce431e1d │
└────────────┴──────────────────────────────────────────────────────────────────┘

6. 在项目根目录添加react-native-code-push

npm install react-native-code-push --save
#或者
yarn add react-native-code-push

7. link react-native-code-push

react-native link

? What is your CodePush deployment key for Android (hit <ENTER> to ignore) T0NshYi9X8nRkIe_cIRZGbAut90a6dec4087-57cf-4c9d-b0dc-ad38ce431e1d

#将刚才添加的Android App的Deployment Key复制粘贴到这里,复制名为Staging测试Deployment Key。

#继续复制Ios的Deployment Key

Running android postlink script

8. 在react-native的App.js文件添加自动更新代码

...
import codePush from "react-native-code-push";
const codePushOptions = { checkFrequency: codePush.CheckFrequency.MANUAL };
export default class App extends Component<{}> {

  componentDidMount(){
    codePush.sync({
      updateDialog: true,installMode: codePush.InstallMode.IMMEDIATE,mandatoryInstallMode:codePush.InstallMode.IMMEDIATE,//deploymentKey为刚才生成的,打包哪个平台的App就使用哪个Key,这里用IOS的打包测试
      deploymentKey: 'IjC3_iRGEZE8-9ikmBZ4ITJTz9wn6dec4087-57cf-4c9d-b0dc-ad38ce431e1d',});
  }
  ...

9. 运行项目在ios模拟器上

react-native run-ios

如图下所显
1:开启debug调试
2:CodePush已经成功运行
目前App已经是最新版本

10. 发布一个ios新版本

code-push release-react dounineApp-ios ios
#发布成功如图下
Detecting ios app version:

Using the target binary version value "1.0" from "ios/dounineApp/Info.plist".

Running "react-native bundle" command:

11. 重新Load刷新应用

12. 安卓发布
与上面9~11步骤是一样的，命令改成Android对应的,以下命令结果简化

#1.修改App.js的deploymentKey为安卓的
...
deploymentKey:'T0NshYi9X8nRkIe_cIRZGbAut90a6dec4087-57cf-4c9d-b0dc-ad38ce431e1d'
...
#2.运行
react-native run-android
#3.发布
code-push release-react dounineApp-android android
#4.刷新应用,如下图

至此已经完成RN热更新,进阶内容请参考其它文章。
