React-Native熱更新 - 3分鐘教你實現

哈哈,今天是大豬在簡書寫的第一篇文章,步入正題,此文使用當前最新版本的RNCode-Push進行演示,其中的參數不會過多進行詳細解釋,更多參數解釋可參考其它文章,這里只保證APP能正常進行熱更新操作,方便快速入門,跟著大豬一起來快活吧。

操作指南

以下操作在Mac系統上完成的,畢竟 大豬 工作多年之后終于買得起一個Mac了。

  1. 創建React-Native項目
react-native init dounineApp
  1. 安裝code-push-cli
npm install -g code-push-cli
  1. 注冊code-push帳號
code-push register
Please login to Mobile Center in the browser window we've just opened.

Enter your token from the browser:
#會彈出一個瀏覽器,讓你注冊,可以使用github帳號對其進行授權,授權成功會給一串Token,點擊復制,在控制進行粘貼回車(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.
  1. code-push添加一個ios的app
code-push app add dounineApp-ios ios react-native
#成功提示如下方

┌────────────┬──────────────────────────────────────────────────────────────────┐

└────────────┴──────────────────────────────────────────────────────────────────┘
  1. 繼續在code-push添加一個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                                                   │
├────────────┼──────────────────────────────────────────────────────────────────┤

└────────────┴──────────────────────────────────────────────────────────────────┘
  1. 在項目根目錄添加react-native-code-push
npm install react-native-code-push --save
#或者
yarn add react-native-code-push
  1. link react-native-code-push
react-native link

#將剛才添加的Android App的Deployment Key復制粘貼到這里,復制名為Staging測試Deployment Key。

#繼續復制Ios的Deployment Key

Running android postlink script
  1. react-nativeApp.js文件添加自動更新代碼
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為剛才生成的,打包哪個平臺的App就使用哪個Key,這里用IOS的打包測試
      deploymentKey: 'IjC3_iRGEZE8-9ikmBZ4ITJTz9wn6dec4087-57cf-4c9d-b0dc-ad38ce431e1d',
      });
  }
  ...
  1. 運行項目在ios模擬器上
react-native run-ios

如圖下所顯

1:開啟debug調試

2:CodePush已經成功運行

目前App已經是最新版本

  1. 發布一個ios新版本
code-push release-react dounineApp-ios ios

發布成功如圖下

  1. 重新Load刷新應用
  1. 安卓發布

與上面9~11步驟是一樣的,命令改成Android對應的,以下命令結果簡化

1.修改App.js的deploymentKey為安卓的

deploymentKey:'T0NshYi9X8nRkIe_cIRZGbAut90a6dec4087-57cf-4c9d-b0dc-ad38ce431e1d'

2.運行

react-native run-android

3.發布

code-push release-react dounineApp-android android

4.刷新應用,如下圖
