Egg: 折腾了2个小时，还是没有搞定如何断点调试 egg.js

[yandongxu]

试了 Webstorm 和 VS Code，看遍 Issues 也没搞定断点调试。。。
好伤啊

[atian25]

。。。 webstorm 的写在文档那边了，没看到？

vscode 的用 @okalala 写的插件

Webstorm 的控制台输出如下:

Webstorm 可以直接在 index.js 右键点调试. 我感觉有时候会进不了断点,关了调试重新点启动再试一次就可以了.
Webstorm 里面单元测试 设断点还不知道怎么搞. 因为会先加载.setup.js 有些变量会没有值,也不知道有谁试过没有,webstorm 里面那个单元测试 的调试还是挺好用的,点右键就能只跑某个用例.

[okoala]

@yandongxu
我最近写了一个插件egg-development-proxyworker，支持在vscode中断点调试，修改文件后会自动重新attach，断点位置不变。你可以先试试看，不清楚的地方可以@我

[popomore]

@okoala 可以加到调试文档里去

[okoala]

@popomore OK

[atian25]

@yandongxu 只有这么点日志？看日志是 master 启动 debug 端口是 49731， agent 也启动了，端口是 5856，然后 worker 没看到日志了。

启动脚本改为： echo $NODE_DEBUG_OPTION; egg-bin dev $NODE_DEBUG_OPTION 然后给多点日志看看

[Rwing]

vs code market 里有一个叫 egg.js dev tools 的东西，这个应该也可以吧？

[atian25]

@Rwing 两者原理不一样的，@okoala 这个插件是跟 IDE 无关的，它主要是启动了一个 socket 代理 worker 的调试 socket，这样 worker 重启后，IDE 还是连接同一个端口。

那个 vscode 扩展是 @yuzukwok 在 https://github.com/eggjs/egg/issues/583 做的，应该可以改改用到前者的东西。

WebStorm 的那个我试了下， 可以复现，还是 WebStorm 在 Node 7.x 的问题，用 Node 6.x 就可以。

[atian25]

@yandongxu vscode 的那个，从你的看来是 egg 没开启 debug，贴下 egg 的启动日志。

[yandongxu]

你没启动 debug 啊...

用 npm run dev -- --debug 或者放到 npm scripts 里面

[yandongxu]

@atian25 @okoala Vs Code 可以了！不过建议 npm run dev -- -- debug 最好加到文档里.

另外, Webstorm 有没有解决方案?

[atian25]

https://eggjs.org/zh-cn/core/development.html#使用-webstorm-进行调试 这里有写的。

@okoala 看你 README 那边是不是漏了

[atian25]

WebStorm 那个，要不你用 6.x，要不就是去 WebStorm 那边提 issue： debug cluster at node 7.x

[okoala]

@yandongxu 把启动配置也加到vscode的launch.json里是最好的了，一键启动+调试

[yandongxu]

@okoala @atian25 谢谢. 这个可以关了吧?

[junmaqiang]

可以出一个支持Atom的调试文档?

[atian25]

atom 啊，@fengmk2

[dead-horse]

不要 at 我们，我们都是 console 调试的

[popomore]

不要再问调试的事情了，自己解决
