function readableStreamFromReader
readableStreamFromReader(
reader: Reader | (Reader & Closer),
): ReadableStream<Uint8Array>
Deprecated

(will be removed after 1.0.0) Use toReadableStream instead.

Create a ReadableStream of Uint8Arrays from a Reader.

When the pull algorithm is called on the stream, a chunk from the reader will be read. When null is returned from the reader, the stream will be closed along with the reader (if it is also a Closer).

An example converting a Deno.FsFile into a readable stream:

import { readableStreamFromReader } from "@std/streams/readable_stream_from_reader";

const file = await Deno.open("./file.txt", { read: true });
const fileStream = readableStreamFromReader(file);

Parameters

reader: Reader | (Reader & Closer)
optional
options: ReadableStreamFromReaderOptions

Return Type

ReadableStream<Uint8Array>
