前端小纠结--VS Code调试配置分享

这不是一篇科普文，只是一篇浏览器调试配置的分享（主要对准对准vs code调试）

调试配置

使用vs code插件debugger-for-chrome和 debugger-for-edge(EdgeHTML&Chromium) 调试之前，会自动在工程下添加 .vscode 文件夹，里面的 launch.json 就是配置调试参数的位置。

launch.json

很多的配置参数，具体看参考章节的 nodejs-debugging 和 debugging-protocol 。

launch模式

launch模式就是重新打开一个浏览器实例（不是tab）。

attach模式

attach模式，是附加到现在已经打开的浏览器调试端口上，所以需要你在已经打开的浏览器中访问 launch.json 中配置的网站地址。

chrome配置

• windows

• mac

  终端执行: /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222

• Linux

  终端执行： google-chrome --remote-debugging-port=9222

Edge(Chromium)

• windows

命令行： msedge.exe --remote-debugging-port=2015

• mac和Liunx现在官方没说怎么调试.....

Microsoft Edge (EdgeHTML)

• windows

  命令行： microsoftedge.exe --devtools-server-port=2015

  竟然不能快捷方式配置，不科学。

个人建议

个人建议平时开发，把端口配置到快捷方式，使用attach模式可以共享使用已经安装的浏览器插件。

具体还有很多参数配置，可以参考官方文档。
