interpreted as compiled addon modules loaded with dlopen. 如果没有找到确切的文件名，node 将尝试以追加扩展名.js 后的文件名读取文 件，如果还是没有找到则尝试追加扩展名.node。.js 文件被解释为 JavaScript 格式的纯文本文件，.node 文件被解释为编译后的 addon（插件） 模块，并使用 dlopen 来加载。 js is a file, load X.js as JavaScript text. STOP 3. If X.node is a file, load X.node as binary addon. STOP LOAD_AS_DIRECTORY(X) 1. If X/package.json is a file, a. Parse X/package.json, and 已将所有依赖关系静态地编译成可执行文件，因此我们在编译自己的组件 时不需要担心和这些类库的链接问题。 To get started let's make a small Addon which does the following except in C++: 让我们着手编写一个 Addon 的小例子，来达到如下模块同样的效果： exports.hello = 'world'; To get started we create

实际应用以计算为主(CPU密集)，对多任务并行有需求 3. 并行任务在通信上的性能要求 Node.js对多任务的支持： 1. 多进程及多进程集群(cluster) 2. Node.js Addon + pthread 3. (JavaScript Webworker + postMessage + onMessage) 13 YunOS实现了Worker + SAB: 1.
