> 哈哈，今天是大猪在写的第一篇文章,步入正题，此文使用当前最新版本的`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，跟着大猪一起来快活吧。
## 操作指南
以下操作在Mac系统上完成的，毕竟 大猪 工作多年之后终于买得起一个Mac了。
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
```

#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。

```
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
```

```
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
