readable.wrap(stream)
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.
});
