ReadStream - fs - Node documentation
class ReadStream
extends stream.Readable

Usage in Deno

import { ReadStream } from "node:fs";

Instances of fs.ReadStream are created and returned using the createReadStream function.

Properties

bytesRead: number

The number of bytes that have been read so far.

path: string | Buffer

The path to the file the stream is reading from as specified in the first argument to fs.createReadStream(). If path is passed as a string, thenreadStream.path will be a string. If path is passed as a Buffer, thenreadStream.path will be a Buffer. If fd is specified, thenreadStream.path will be undefined.

pending: boolean

This property is true if the underlying file has not been opened yet, i.e. before the 'ready' event is emitted.
