fsPromises.opendir(path[, options])

• path <string> | <Buffer> | <URL>
• options <Object>
  • encoding <string> | <null> 默认值: 'utf8'
  • bufferSize <number> 当从目录读取时，在内部缓冲的目录条目数。 值越大，性能越好，但内存使用率越高。 默认值: 32
• 返回: <Promise> 包含 <fs.Dir>

异步地打开目录。 参见 opendir(3)。

创建 fs.Dir，其中包含用于从目录读取和清理目录的所有进一步的函数。

encoding 选项设置在打开目录和随后的读取操作时 path 的编码。

使用异步迭代的示例：

const fs = require('fs');

async function print(path) {
  const dir = await fs.promises.opendir(path);
  for await (const dirent of dir) {
    console.log(dirent.name);
  }
}
print('./').catch(console.error);

• path <string> | <Buffer> | <URL>
• options <Object>
  • encoding <string> | <null> Default: 'utf8'
  • bufferSize <number> Number of directory entries that are buffered internally when reading from the directory. Higher values lead to better performance but higher memory usage. Default: 32
• Returns: <Promise> containing <fs.Dir>

Asynchronously open a directory. See opendir(3).

Creates an fs.Dir, which contains all further functions for reading from and cleaning up the directory.

The encoding option sets the encoding for the path while opening the directory and subsequent read operations.

Example using async iteration:

const fs = require('fs');

async function print(path) {
  const dir = await fs.promises.opendir(path);
  for await (const dirent of dir) {
    console.log(dirent.name);
  }
}
print('./').catch(console.error);
