Build vscode, host it localhost and run it in browser

https://www.barretlee.com/blog/2019/10/23/vscode-study-01-start/ Visual Studio Code 是微软推出的一款轻量级编辑器,与它一起在市场争锋的相似软件还有 Atom 和 Sublime Text,面世第二年的它只占据 7% 左右的市场,后来在短短三年时间雄踞了半壁江山,不可谓不哇塞。 发育如此强势的软件,背后到底是如何设计的,未来一段时间,我将带着你一点一点拨开她的面纱,再撩开她的裙摆。 下载源码 Visual Studio Code 简称 VSCode,需要注意的是,平时我们使用的 VSCode 那是产品,而下面我们要介绍的是源码,产品是源码的构建结果;源码使用的 MIT License,而产品使用的是这个 MICROSOFT SOFTWARE LICENSE TERMS,如果你想把 VSCode 用于商用,建议从源码构建出新的产品,而不是直接使用人家官网上提供下载链接的 VSCode Product。 官网地址是 https://code.visualstudio.com/ 源码在这里:https://github.com/microsoft/vscode。 我们先把源码 down 下来: git clone –depth 1 https://github.com/microsoft/vscode.git 由于 VSCode 项目过于活跃,提交量非常庞大,到目前为止,已经有 56,092 次提交了,建议在下载源码的时候加了一句 –depth 1,意思就是只现在最近一次 commit 的代码。 30s 后……71M,不慢。 安装依赖 在安装依赖之前,我们不妨稍微分析下 VSCode 的项目结构, ➜ vscode (master) tree -L…
