readable.wrap(stream)

• stream <Stream> "老式" 可读流

  \stream <Stream> An "old style" readable stream

• 返回:<this>

  \Returns: <this>

在 Node.js 0.10 之前,流没有实现当前定义的整个 node:stream 模块 API。(有关详细信息,请参阅 兼容性。)

\Prior to Node.js 0.10, streams did not implement the entire node:stream module API as it is currently defined. (See Compatibility for more information.)

当使用触发 'data' 事件并具有仅供参考的 stream.pause() 方法的旧 Node.js 库时,readable.wrap() 方法可用于创建使用旧流作为其数据源的 Readable 流。

\When using an older Node.js library that emits 'data' events and has a stream.pause() method that is advisory only, the readable.wrap() method can be used to create a Readable stream that uses the old stream as its data source.

很少需要使用 readable.wrap(),但提供该方法是为了方便与旧的 Node.js 应用和库进行交互。

\It will rarely be necessary to use readable.wrap() but the method has been provided as a convenience for interacting with older Node.js applications and libraries.

const { OldReader } = require('./old-api-module.js');
const { Readable } = require('node:stream');
const oreader = new OldReader();
const myReader = new Readable().wrap(oreader);
myReader.on('readable', () => {
 myReader.read(); // etc.
}); 拷贝
