基于React的微前端项目构建时Node V8内存溢出问题解决(Ineffective mark-compacts near heap limit Allocation failed)_react内存溢出

项目场景：

最近在写前端的React项目，项目用的是阿里飞冰的icestark微前端解决方案，面向大型系统的微前端解决方案，前端的每个模块都拆分成了微模块。编译好后在集成到主应用中。

问题描述 

由于单个微模块也是挺大的，热更新时随便改动下就经常报NodeJS的V8引擎内存堆栈溢出问题。

原因分析：

Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
 

JavaScript堆内存不足，Node 是基于V8引擎，在一般的后端开发语言中，在基本的内存使用上没有什么限制，但是在 Node 中通过 JavaScript 使用内存时只能使用部分内存（64位系统下约为1.4 GB，32位系统下约为0.7 GB），这就是编译项目时为什么会出现内存泄露了，因为前端项目如果非常的庞大，webpack 编译时就会占用很多的系统资源，如果超出了V8对 Node 默认的内存限制大小就会报这个错误。
 

解决方案：

由于使用的微前端的架构，构建工具也是使用阿里飞冰的build-scripts模块，所以使用在网上查到的vue项目的内存溢出配置也是无效，比如这样也是错误的

【build-scripts -max_old_space_size=8000 start】

只有改成下面的方式才有效。

node --max_old_space_size=8000 node_modules/.bin/build-scripts start

node --max_old_space_size=8000 node_modules/.bin/build-scripts start
