RN拆包，debug是完全OK的，但是release爆了空指针异常，大概是什么问题呢？

hi,大佬,请教一下这个现在06有问题么? 是否测试过啊，还更新么？

最新的rn项目中这个方法被取消了吗?

你好，有个问题请教一下。

在有多个业务包的情况下，每个业务包内都有几个页面，那么如何判断某个页面属于哪个业务包？这样根据要进入页面加载对应的业务包。按Demo的做法是在原生侧写死了业务包和对应的页面，这样会限制在js侧动态添加、删除页面，是否能支持在打开RN页面之前，先从js侧读取最新的业务包-页面对应表，然后再加载对应的业务包？

com.facebook.react.common.JavascriptException: Requiring unknown module "node_modules_@babel_runtime_helpers_taggedTemplateLiteralLoose".

界面就是一个简单的跳转
然后根据文档进行分包操作，通过buz-ui.config.js，命令行进行打包，相继出现找不到第三方包的错，通过issues找到添加对应的第三方依赖

之后重新打包，出现以下的错误
，不知道什么原因

我加上react-navigation这个包之后报错，
Requiring unknown module "node_modules_react-navigation_src_react-navigation"

react-native-multibundler-master/ios/assets: No such file or directory 报这个错误
感谢感谢

比如我这边有三个包，一个基础包，两个业务包A和B，我现在的需求是业务包A里面需要引用业务包B里的js文件，请问可以这样吗？还是说要先加载业务包B，然后在加载业务包A，这样就可以？

我把

• (void)executeSourceCode:(NSData *)sourceCode sync:(BOOL)sync;
  添加到@interface RCTCxxBridge里, 但是bridge.batchedBridge还是找不到executeSourceCode这个函数, 这是为啥

Requiring unknown module "node_modules_@babel_runtime_helpers_interopRequireDefault"

大佬，打包之后加载业务包，提示这个错误，是什么原因呢？

var _ = require('lodash');
Text.render = _.wrap(Text.render, function (func, ...args) {
let originText = func.apply(this, args)
return React.cloneElement(originText, {allowFontScaling: false})
})

请问platformDep.js中这段代码的作用是什么？望不吝赐教

离开应用后，再回到应用，就报java.lang.AssertionError: createReactContextInBackground should only be called when creating the react application for the first time. When reloading JS, e.g. from a new file, explicitlyuse recreateReactContextInBackground。

能否告知下解决方案?

遇到几点疑问，需要和您交流以下。可以留下微信或qq联系方式吗？非常感谢。

platformEmptyDefaultExport 这个有什么用途呢

node ./node_modules/react-native/local-cli/cli.js bundle --platform android --dev false --entry-file index.js --bundle-output ./android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/ --config /{你的绝对路径}/buz57.config.js

将 index 都换成 index3 打包出来的 包大小不对， 运行报错

package.json

基础包
"bundle-ios-platform": "node ./node_modules/react-native/local-cli/cli.js bundle --platform ios --dev false --entry-file platformDep.js --bundle-output ios/bundle/platform.jsbundle --assets-dest ./ios/ --config $(pwd)/platform57.config.js",

业务包
"bundle-ios-buz": "node ./node_modules/react-native/local-cli/cli.js bundle --platform ios --dev false --entry-file index.js --bundle-output ios/bundle/buz.jsbundle --assets-dest ./ios/ --config $(pwd)/buz57.config.js",

其中基础包配置 platformEmptyDefaultExport.js 中 必须要
import 'redux-logger'
因为业务包里用到了这个库，但这个库本应该在dev中，虽然业务包脚本指定了 --dev false，但为什么业务包中还是会用到呢？
我的理解是 如果指定 --dev false, 那么打包的时候会略过。
可能是因为现在业务包的配置没能忽略 devDependencies, 如果是这样，怎么配置忽略 devDependencies?

使用codepush热更新，更新完的assets中的图片无法加载，怎么解决跨域问题

我这是ios的工程, 如果我在这个demo目录下直接npm start, 里面的模块会加载失败, 请问这种多模块的开发要怎么弄

遇到了这个问题，请问该怎么解决

希望大神就基础包打包配置,和业务包打包配置有更详细的说明和演示,比如加入第三方组件时要怎么配置?

Could not resolve all dependencies for configuration ':app:debugRuntimeClasspath'.
Could not determine artifacts for com.facebook.fresco:fresco:1.10.0: Skipped due to earlier error

相同名称的业务包从网络重新加载,界面不刷新,大神有没有碰到这种使用场景,怎么解决的

iOS打业务包后，图片只能引用到基础包asserts里面图片，请问需要怎么处理
通过alert可以看到图片路径是基础包asserts里面图片，而不是业务包里面的图片路径，从而导致图片显示不出来

I tried to split by bundles, and when do the bridge initialization, it's take 1 ~ 2s. The white screen is occurred longer than I though. Is there a way to speed up?

问题1: 使用介绍的方法打包，打出的platform包与原来的包有却别。这是正常的吗？
问题2: 打出的buz包，与原来包相比少了几个模块！且无法正常运行

node ./node_modules/react-native/local-cli/cli.js bundle --platform ios --dev true --entry-file platformDep.js --bundle-output ./ios/platform.ios.bundle --assets-dest ./ios/ --config {绝对路径}/platform57.config.js
--dev 改成true，打出的基础包，iOS加载会报错，如下图:

谢谢大神分享的代码O(∩_∩)O
我的项目中使用了Redux，分包的时候是共用一份store吗？
还是建多个store，各用各的？
其中有一个reducer是用来做主题颜色切换的，所有的业务包都需要用到，这样的话只能共用一个store才能做到了。有没有更好的方式呢？

• (instancetype)initWithBundleURL:(NSURL *)bundleURL
  moduleProvider:(RCTBridgeModuleListProvider)block
  launchOptions:(NSDictionary *)launchOptions
  大神指导怎么监测基础包何时完全加载完成么?
  我如果加载完基础包,立即加载业务包,会报错,加个延时就可以,之所以重新加载基础包,是因为这样相同的业务包名文件就可以刷新
  appDelegate.bridge = [[RCTBridge alloc] initWithBundleURL:jsCodeLocation
  moduleProvider:nil
  launchOptions:appDelegate.launchOptions];
  [appDelegate.bridge.batchedBridge executeSourceCode:sourceBuz sync:YES];

感觉涉及这两个业务包根本没有他的功能了，我提到的这两个都只能放在基础包里面。。。或许只能修改源码了吧！

我照着你这样写只能加载一个业务包，加载第二个的时候就会报 Application has not been registered. 请问可能的问题有哪些

我是在native下载完包后把业务包里的图片都拷贝到基础包路径

你好,我也碰到同样的问题,能否分享一下具体做法???
