当多个项目需要打字稿时,有没有办法减少 VS Code 中的 node.js 任务/进程?

我将 Visual Studio Code (VSCode) 用于一个更大的项目,我们在一个工作区中有大约 10 到 15 个子 git 项目。

所有这些项目都是 Typescript,所以我使用 tasks.json + vscode Option Tasks: Manage Automatic Tasks in Folder

这导致 10-15 个节点进程,每个进程使用大约 1-4% CPU 使用率。不幸的是,我打开了多个工作空间,所以我最终有很多节点进程,不仅消耗我的内存,还消耗我的 cpu

It heats up my pc and I want to know if this can be prevented. 

有些项目我经常更改(2-3),有些项目总是在master上,我大麦从来没有碰过它们。你有任何最佳实践来克服这个问题吗?

我在屏幕上的问题: my screen

stack overflow Is there a way to reduce node.js tasks/ processes in VS Code while typescript is required for multiple projects?

接受的答案

我意外地找到了解决方案,因为我试图减少任务量,但如何减少每项任务的影响呢?

解决方案

设置环境变量

TSC_NONPOLLING_WATCHER="1" 

在我的例子中,我不得不通过调整 .zprofile

export TSC_NONPOLLING_WATCHER="1"

区别在这里得到了完美的解释: https://medium.com/@julioromano/writing-typescript-on-a-laptop-this-might-improve-your-battery-life-f503dd16f019

我什至可以帮助另一个人解决他 2 年前遇到的同样问题: Does tsc-watch consume TSC_NONPOLLING_WATCHER?

总而言之,我真的很高兴,我的笔记本电脑非常安静(使用 2-5% 而不是 30%)。

虽然它减少了如此多的 RAM|CPU 使用率,但您还可以通过排除一些不重要且几乎不接触的文件夹/项目来减少 vscode 用于大型项目的资源量,例如:node_modules、.vscode、git 等...

阅读这篇关于做这件事的 medium article,我写的是......希望它能帮助你一点点......
