Node.jsBuilt-in Modules ❮ PreviousNext ❯ Node.js has a set of built-in modules which you can use without any further installation. Here is a list of the built-in modules of Node.js version 6.10.3: ModuleDescription assertProvides a set of assertion tests ...
./some-library/index.js ./some-library/index.node 从node_modules文件加载 如果传入require()的不是核心模块,并且不是以’/’、’../’、’./’开始的,,然后Node.js从当前模块的父目录开始,并且尝试读取/node_modules下的模块。Node不会在已经是以node_modules结尾的路径下追加node_modules。
因此,JS层面的代码都只是普通的方法分发逻辑,真正的调用都来源于底层的C++。 现在回到C++,直接看关键方法getBinding,只取关键代码: staticvoidGetBinding(constFunctionCallbackInfo<Value>&args) {//...//从链表获取对应模块信息node_module* mod = get_builtin_module(*module_v);//新建输出对象Local<Object>ex...

assert(builtins().includes('http')) Get list of core modules for specific Node.js version: assert(builtins({version:'6.0.0'}).includes('http')) Get list of core modules present in one or mode Node.js versions: assert(builtins({version:'*'}).includes('worker_threads')) ...
首先Node.js 会调用 registerBuiltinModules 函数注册 C++ 模块,这个函数会调用一系列 registerxxx 的函数,我们发现在 Node.js 源码里找不到这些函数,因为这些函数是在各个 C++ 模块中,通过宏定义实现的,宏展开后就是上图黄色框的内容,每个 registerxxx 函数的作用就是往 C++ 模块的链表了插入一个节点,最后会形成...
@mmarchiniYes, it adds it to all built‑in modules. This way, the detection of internal modules can now be done usingmoduleName.startsWith("node:internal/")(example:tapjs/stack-utils@ec0a544). Sorry, something went wrong. MemberAuthor ...
As of node v14.18 and v16, you can now requirenativenode modules, i.e. those things likepath,fs, etc which are built into node, by using thenode:protocol in the import or require statement. This will prevent script writers from accidentally importing 3rd party versions of utilities. ...
nodejs怎么导入node_modules nodejs引入模块 前端笔记之NodeJS(一)初识NodeJS&内置模块&特点 一、NodeJS简介 NodeJS是开发服务器后台的东西,和PHP、JavaEE、python类似,和传统的浏览器的关注DOM的JS完全不同,将JavaScript触角伸到了服务器端。内核是Chrome浏览器的V8引擎,解析JavaScript的效率是非常快的。
