内置模块

🌐 Built-in modules

Node.js 有几个模块被编译进二进制文件。这些模块在本文档的其他部分有更详细的描述。

🌐 Node.js has several modules compiled into the binary. These modules are described in greater detail elsewhere in this documentation.

内置模块是在 Node.js 源码中定义的，位于 lib/ 文件夹中。

🌐 The built-in modules are defined within the Node.js source and are located in the lib/ folder.

内置模块可以使用 node: 前缀来识别，在这种情况下，它会绕过 require 缓存。例如，即使存在同名的 require.cache 条目，require('node:http') 也总是会返回内置的 HTTP 模块。

🌐 Built-in modules can be identified using the node: prefix, in which case it bypasses the require cache. For instance, require('node:http') will always return the built in HTTP module, even if there is require.cache entry by that name.

如果将内置模块的标识符传递给 require()，某些内置模块总是优先加载。例如，require('http') 总是返回内置的 HTTP 模块，即使存在同名文件。可以在不使用 node: 前缀的情况下加载的内置模块列表显示为 module.builtinModules。

🌐 Some built-in modules are always preferentially loaded if their identifier is passed to require(). For instance, require('http') will always return the built-in HTTP module, even if there is a file by that name. The list of built-in modules that can be loaded without using the node: prefix is exposed as module.builtinModules.
