1.以前cordova远程调试，Android的直接连接USB后，用chrome打开chrome://inspect网址
（有人遇到第一次打开chrome inspect是空白页面，是因为第一次要下载一些工具，是要*的。当然有离线包可用，具体可以网上搜索。）
IOS的打开Safari的developer下。
这是因为cordova的webView都已经开放了远程调试，
如果是自己的加的webView,要进行远程调试
Android:
在调试WebView需要满足安卓系统版本为Android 4.4+已上。并且需要再你的APP内配置相应的代码，在WebView类中调用静态方法setWebContentsDebuggingEnabled，如下：
if (Build.VERSION.SDK_INT >=Build.VERSION_CODES.KITKAT) {
WebView.setWebContentsDebuggingEnabled(true);
}
IOS：
利用WebView隐含的一个API
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// ......
[NSClassFromString(@"WebView") _enableRemoteInspector];
// ......
}
不过这是个私有API,ARC关闭的情况下才能这么写，不然会报错。
微信：
利用微信开发者工具进行远程调试，具体操作很简单
2.远程调试可以debug那些web上看不出来，但是在在device上就出问题的情况
1.weex安装完weex-toolkit
$ npm install -g weex-toolkit
就可以直接通过weex debug命令进行调试
2.比如下载的weex demo,进入根目录，运行weex debug examples
就会出现一些二维码页面，用playground app扫这个二维码,浏览器里出现如下页面
点击remotedebug按钮就可以进行远程调试了
真机调试微信(android,ios)H5页面：https://www.jianshu.com/p/c620ef778e1c
3.React Native
在运行带RN的工程后，当前页面下ios模拟器通过cmd+D(真机可以通过摇一摇),android通过Menu按键，调出RN的开发者菜单， 4.electron和node调试(vscode中)

}
vscode的launch.json里添加配置，然后就可以在vscode里打断点调试node或者RN项目了
"runtimeExecutable": "/Users/johnzhu/.nvm/versions/node/v13.2.0/bin/node" 可以切换所使用的node版本
上面的第一个configure是调试node的，比如我的encrypt.js
第二个是调试npm 脚本
第三个调试webpack，并且加参数的
第四个是调试electron的，目录那么长是因为是我自己的一个脚手架项目(https://github.com/johnzhu12/generator-rocky)，electron的目录比较深
各个配置的目录各不相同，对应自己项目的目录设置
最后deBugger jest
5.vscode调试karma debugging Karma with Visual Studio Code 这里debug的断点一定要打在sourcemap里，大在源码里是不会被hit的
6. vscode 配置c/c++环境
clang编译c,clang++编译c++
launch.json和task.json
"configurations": [
{
"name": "clang++ build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",

}
}
],

}
c_cpp_properties.json
{
"configurations": [

上面配置都自己试过，亲测有用
