import { Readable } from "https://deno.land/std@0.162.0/node/stream.ts";
Prior to Node.js 0.10, streams did not implement the entire stream
module API
as it is currently defined. (See Compatibility
for more information.)
When using an older Node.js library that emits 'data'
events and has a pause method that is advisory only, thereadable.wrap()
method can be used to create a Readable
stream that uses
the old stream as its data source.
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('stream');
const oreader = new OldReader();
const myReader = new Readable().wrap(oreader);
myReader.on('readable', () => {
myReader.read(); // etc.
});
Parameters
stream: ReadableStream
An "old style" readable stream
