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]

打包步骤

1.在工程根目录下执行打包命令，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/]文件夹存在。

2.增量升级的话不要把图片资源直接打包到res中，脚本如下：
react-native bundle --entry-file index.android.js --bundle-output ./bundle/androidBundle/index.android.jsbundle --platform android --assets-dest ./bundle/androidBundle/ --dev false

3.保证MainActivity.Java中的setBundleAssetName与你的jsbundle文件名一致，比如.setBundleAssetName(“index.android.jsbundle”)就与我生成的资源名一致

IOS

–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”]

–verbose Enables logging [default: false]

1.在工程根目录下执行打包命令，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
注意要先保证bundle文件夹存在。
2.在xcode中添加assets【必须用Create folder references的方式，添加完是蓝色文件夹图标】和index.ios.jsbundle
3.参考官方文档，修改AppDelegate.m文件,使用OPTION 2处的代码 jsCodeLocation = [[NSBundle mainBundle] URLForResource:@”index.ios” withExtension:@”jsbundle”];

ios打包遇到的问题

1.离线包如果开启了chrome调试，会访问调试服务器，而且会一直loading出不来。 2.如果bundle的名字是main.jsbundle,app会一直读取旧的,改名就好了。。。非常奇葩的问题，我重新删了app，clean工程都没用，就是不能用main.jsbundle这个名字。 3.必须用Create folder references【蓝色文件夹图标】的方式引入图片的assets，否则引用不到图片 4.执行bundle命令之前，要保证相关的文件夹都存在
