ReadableStreamBYOBReader

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The ReadableStreamBYOBReader interface of the Streams API represents a BYOB ("bring your own buffer") reader that can be used to read stream data supplied by the developer (e.g. a custom ReadableStream() constructor).

Constructor

ReadableStreamBYOBReader()
Creates and returns a ReadableStreamBYOBReader object instance.

Properties

ReadableStreamBYOBReader.closed Read only
Allows you to write code that responds to an end to the streaming process. Returns a promise that fulfills if the stream becomes closed or the reader's lock is released, or rejects if the stream errors.

Methods

ReadableStreamBYOBReader.cancel()
Cancels the stream, signaling a loss of interest in the stream by a consumer. The supplied reason argument will be given to the underlying source, which may or may not use it.
ReadableStreamBYOBReader.read()
Returns a promise providing access to the next chunk in the stream's internal queue.
ReadableStreamBYOBReader.releaseLock()
Releases the reader's lock on the stream.

Examples

TBD.
