IDE 开发工具对 NODEJS 有一定依赖,不安装不保证功能。如NPM依赖管理,不安装会导致不能下载更新node_modules 中依赖。 2鼠标悬停计算机界面> 右键选择属性>高级系统设置>环境变量。 3在环境变量/系统变量中找到 path 并编辑,在末尾添加本地 nodejs 安装的路径,如:";D:\\mywork\odeJS\\"(node 安装路径前面用...

second, info, waiting); }} WorkerStarted记录了一个id和上下文,因为delegates_初始化的时候是空的,所以不会执行。至此,子线程Inspector初始化的逻辑就分析完了,结构图如下。我们发现,和主线程不一样,主线程会启动一个WebSocket服务器接收客户端的连接请求,而子线程只是初始化了一些数据结构。下面我们看一下基于...
node-sync is a simple library that allows you to call any asynchronous function in synchronous way. The main benefit is that it uses javascript-native design - Function.prototype.sync function, instead of heavy APIs which you'll need to learn. Also, asynchronous function which was called synchr...
