fsPromises.readdir(path[, options])

• path <string> | <Buffer> | <URL>
• options <string> | <Object>
  • encoding <string> 默认值: 'utf8'
  • withFileTypes <boolean> 默认值: false
• 返回: <Promise>

可选的 options 参数可以是指定编码的字符串，也可以是具有 encoding 属性（指定用于文件名的字符编码）的对象。 如果 encoding 设置为 'buffer'，则返回的文件名将作为 Buffer 对象传入。

如果 options.withFileTypes 设置为 true，则解决的数组将包含 fs.Dirent 对象。

const fs = require('fs');

async function print(path) {
  const files = await fs.promises.readdir(path);
  for (const file of files) {
    console.log(file);
  }
}
print('./').catch(console.error);

• path <string> | <Buffer> | <URL>
• options <string> | <Object>
  • encoding <string> Default: 'utf8'
  • withFileTypes <boolean> Default: false
• Returns: <Promise>

Reads the contents of a directory then resolves the Promise with an array of the names of the files in the directory excluding '.' and '..'.

The optional options argument can be a string specifying an encoding, or an object with an encoding property specifying the character encoding to use for the filenames. If the encoding is set to 'buffer', the filenames returned will be passed as Buffer objects.

If options.withFileTypes is set to true, the resolved array will contain fs.Dirent objects.

const fs = require('fs');

async function print(path) {
  const files = await fs.promises.readdir(path);
  for (const file of files) {
    console.log(file);
  }
}
print('./').catch(console.error);
