filehandle.readLines([options])

• options <Object>
  • encoding <string> 默认值: null
  • autoClose <boolean> 默认值: true
  • emitClose <boolean> 默认值: true
  • start <integer>
  • end <integer> 默认值: Infinity
  • highWaterMark <integer> 默认值: 64 * 1024
• 返回: <readline.InterfaceConstructor>

创建 readline 接口和流过文件的便捷方法。 有关选项，请参见 filehandle.createReadStream()。

import { open } from 'node:fs/promises';

const file = await open('./some/file/to/read');

for await (const line of file.readLines()) {
  console.log(line);
}const { open } = require('node:fs/promises');

(async () => {
  const file = await open('./some/file/to/read');

  for await (const line of file.readLines()) {
    console.log(line);
  }
})();

• options <Object>
  • encoding <string> Default: null
  • autoClose <boolean> Default: true
  • emitClose <boolean> Default: true
  • start <integer>
  • end <integer> Default: Infinity
  • highWaterMark <integer> Default: 64 * 1024
• Returns: <readline.InterfaceConstructor>

Convenience method to create a readline interface and stream over the file. See filehandle.createReadStream() for the options.

import { open } from 'node:fs/promises';

const file = await open('./some/file/to/read');

for await (const line of file.readLines()) {
  console.log(line);
}const { open } = require('node:fs/promises');

(async () => {
  const file = await open('./some/file/to/read');

  for await (const line of file.readLines()) {
    console.log(line);
  }
})();
