运行一段时间后内存溢出的问题 #26

Closed songyazhao closed 6 years ago

songyazhao commented 6 years ago

前端vue的东西修改发生热更新，过一段时间之后报错如下。 看网上的方案是在dev的时候加上node --max_old_space_size=4096。 但是只能延缓出现这个错误的时间。 暂时的解决方法就是重启dev。 感觉很繁琐，有没有更好的办法解决一下。 看了vue-cli生成的项目不会出现这个问题，所以是否可以借鉴下它的内部是如何运作热更新释放内存中的资源。

dev下，热重启多几次就会js heap out of memory，作者赶紧解决下吧，开发时得不停的手动杀进程重启

hubcarl commented 6 years ago

这个估计是 ts-loader 有关，你这个项目构建的文件很大？

@hubcarl 不是因为 ts-loader，前端没有使用 ts ，整个项目架构是基于 egg-vue-typescript-boilerplate ，然后把项目的前端部分替换成了js实现 现在项目也不是很大，十来个页面的样子。目前看来是和前端的热更新有关，后端的代码怎么改也是没事的。

hubcarl commented 6 years ago

@songyazhao 你在看看， easywebpack4 最近修复了一个问题：https://github.com/hubcarl/easywebpack/compare/4.5.0...4.5.1 怀疑与这个有关
