mini-app-engines

在react native中调用flutter和kraken（后期换webf）做小程序容器

Getting started

$ npm install mini-app-engines --save

进入node_modules/mini-app-engines 去行下 npm run build 打包flutter资源

手动配置

ios

ios/Podfile添加

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
require_relative '../node_modules/mini-app-engines/ios-rn/pods' # 添加这个

platform :ios, '12.0'
install! 'cocoapods', :deterministic_uuids => false

target 'apps' do
  config = use_native_modules!

  # Flags change depending on the env values.
  flags = get_default_flags()
  
  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => flags[:hermes_enabled],
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'appsTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  use_flipper!()
 
  use_mini_app_engines!() # 添加这个

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end

再动行pod install

android

android/build.gradle添加

 repositories {
    // 添加这个
    maven {
        url "$rootDir/../node_modules/mini-app-engines/build/host/outputs/repo"
    } 
    // 添加这个
    maven {
        url "https://storage.googleapis.com/download.flutter.io"
    }
    maven {
        // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
        url("$rootDir/../node_modules/react-native/android")
    }
    maven {
        // Android JSC is installed from npm
        url("$rootDir/../node_modules/jsc-android/dist")
    }
    mavenCentral {
        // We don't want to fetch react-native from Maven Central as there are
        // older versions over there.
        content {
            excludeGroup "com.facebook.react"
        }
    }
    google()
    maven { url 'https://www.jitpack.io' }
}

使用

import MiniAppEngines from 'mini-app-engines';

// 初始化（最好打开时就调用）
MiniAppEngines.initialize(console.log);
// 打开小程序
MiniAppEngines.openApplet(
  'http://https://andycall.oss-cn-beijing.aliyuncs.com/demo/guide-styles.js',
  (text: string) => {
    console.log(text);
  },
);

注意暂时只支持 Flutter 2.8.1、

暂进使用的是 kraken 支持 flutter 2.8.0 ~ 2.8.1 后续跟进 webf 支持 flutter 3.0
