Android
打包命令：
eact-native bundle
Options:
–entry-file Path to the root JS file, either absolute or relative to JS root [required]
–platform Either “ios” or “android”
–transformer Specify a custom transformer to be used (absolute path) [default: “/Users/babytree-mbp13/projects/xcodeProjects/AwesomeProject/node_modules/react-native/packager/transformer.js”]
–dev If false, warnings are disabled and the bundle is minified [default: true]
–prepack If true, the output bundle will use the Prepack format. [default: false]
–bridge-config File name of a a JSON export of __fbBatchedBridgeConfig. Used by Prepack. Ex. ./bridgeconfig.json
–bundle-output File name where to store the resulting bundle, ex. /tmp/groups.bundle [required]
–bundle-encoding Encoding the bundle should be written in (https://nodejs.org/api/buffer.html#buffer_buffer). [default: “utf8”]
–sourcemap-output File name where to store the sourcemap file for resulting bundle, ex. /tmp/groups.map
–assets-dest Directory name where to store assets referenced in the bundle
–verbose Enables logging [default: false]
打包步驟
1.在工程根目錄下執行打包命令，比如
react-native bundle --entry-file index.android.js --bundle-output ./android/app/src/main/assets/index.android.jsbundle --platform android --assets-dest ./android/app/src/main/res/ --dev false
注意:[./android/app/src/main/assets/]文件夾存在。
2.增量升級的話不要把圖片資源直接打包到res中，腳本如下：
react-native bundle --entry-file index.android.js --bundle-output ./bundle/androidBundle/index.android.jsbundle --platform android --assets-dest ./bundle/androidBundle/ --dev false
3.保證MainActivity.java中的setBundleAssetName與你的jsbundle文件名一致，比如.setBundleAssetName(“index.android.jsbundle”)就與我生成的資源名一致
IOS
打包命令：
Options:
–entry-file Path to the root JS file, either absolute or relative to JS root [required]
–platform Either “ios” or “android”
–transformer Specify a custom transformer to be used (absolute path) [default: “/Users/babytree-mbp13/projects/xcodeProjects/AwesomeProject/node_modules/react-native/packager/transformer.js”]
–dev If false, warnings are disabled and the bundle is minified [default: true]
–prepack If true, the output bundle will use the Prepack format. [default: false]
–bridge-config File name of a a JSON export of __fbBatchedBridgeConfig. Used by Prepack. Ex. ./bridgeconfig.json
–bundle-output File name where to store the resulting bundle, ex. /tmp/groups.bundle [required]
–bundle-encoding Encoding the bundle should be written in (https://nodejs.org/api/buffer.html#buffer_buffer). [default: “utf8”]
–sourcemap-output File name where to store the sourcemap file for resulting bundle, ex. /tmp/groups.map
–assets-dest Directory name where to store assets referenced in the bundle
–verbose Enables logging [default: false]
打包步驟
1.在工程根目錄下執行打包命令，比如react-native bundle –entry-file index.ios.js –bundle-output ./bundle/iosBundle/index.ios.jsbundle –platform ios –assets-dest ./bundle/iosBundle –dev false
注意要先保證bundle文件夾存在。
2.在xcode中添加assets【必須用Create folder references的方式，添加完是藍色文件夾圖標】和index.ios.jsbundle
3.參考官方文檔，修改AppDelegate.m文件,使用OPTION 2處的代碼 jsCodeLocation = [[NSBundle mainBundle] URLForResource:@”index.ios” withExtension:@”jsbundle”];
ios打包遇到的問題
1.離線包如果開啓了chrome調試，會訪問調試服務器，而且會一直loading出不來。
2.如果bundle的名字是main.jsbundle,app會一直讀取舊的,改名就好了。。。非常奇葩的問題，我重新刪了app，clean工程都沒用，就是不能用main.jsbundle這個名字。
3.必須用Create folder references【藍色文件夾圖標】的方式引入圖片的assets，否則引用不到圖片
4.執行bundle命令之前，要保證相關的文件夾都存在
