WebTransportSendStream
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The WebTransportSendStream interface of the WebTransport API is a specialized WritableStream that is used to send outbound data in both unidirectional or bidirectional WebTransport streams.
The send stream is a writable stream of Uint8Array, that can be written to in order to send data to a server.
It additionally provides streaming features such as setting the send order, and getting stream statistics.
Objects of this type are not constructed directly.
When creating a unidirectional stream the WebTransport.createUnidirectionalStream() returns an object of this type for sending data.
When creating a bidirectional stream using WebTransport.createBidirectionalStream(), the method returns a WebTransportBidirectionalStream, and the send stream object can be obtained from its writable property.
When a bidirectional stream is initiated by the remote end, an object of this type can similarly be obtained using WebTransport.incomingBidirectionalStreams.
WebTransportSendStream is a transferable object.
Instance properties
Also inherits properties from its parent interface, WritableStream.
WebTransportSendStream.sendOrder-
Indicates the send priority of this stream relative to other streams for which the value has been set.
Instance methods
Also inherits methods from its parent interface, WritableStream.
WebTransportSendStream.getStats()-
Returns a
Promisethat resolves with statistics related to this stream. WebTransportSendStream.getWriter()-
Returns a new
WebTransportWriterobject and locks the stream to it. While the stream is locked, no other writer can be acquired until this one is released.
Examples
See WebTransport.incomingUnidirectionalStreams for an example of how to get a ReadableStream of WebTransportSendStream objects.
