fs 文件系统

源代码: lib/fs.js

node:fs 模块能够以标准 POSIX 函数为模型的方式与文件系统进行交互。

要使用基于 promise 的 API：

import * as fs from 'node:fs/promises';const fs = require('node:fs/promises');

要使用回调和同步的 API：

import * as fs from 'node:fs';const fs = require('node:fs');

所有文件系统操作都具有同步、回调和基于 promise 的形式，并且可以使用 CommonJS 语法和 ES6 模块进行访问。

Source Code: lib/fs.js

The node:fs module enables interacting with the file system in a way modeled on standard POSIX functions.

To use the promise-based APIs:

import * as fs from 'node:fs/promises';const fs = require('node:fs/promises');

To use the callback and sync APIs:

import * as fs from 'node:fs';const fs = require('node:fs');

All file system operations have synchronous, callback, and promise-based forms, and are accessible using both CommonJS syntax and ES6 Modules (ESM).
