Baseline Widely available
Note: This feature is available in Web Workers.
The read-only ByteLengthQueuingStrategy.highWaterMark
property returns the total number of bytes that can be contained in the internal queue before backpressure is applied.
Note: Unlike CountQueuingStrategy()
where the highWaterMark
property specifies a simple count of the number of chunks, with ByteLengthQueuingStrategy()
, the highWaterMark
parameter specifies a number of bytes â specifically, given a stream of chunks, how many bytes worth of those chunks (rather than a count of how many of those chunks) can be contained in the internal queue before backpressure is applied.
An integer.
Examplesconst queuingStrategy = new ByteLengthQueuingStrategy({
highWaterMark: 1 * 1024,
});
const readableStream = new ReadableStream(
{
start(controller) {
// â¦
},
pull(controller) {
// â¦
},
cancel(err) {
console.log("stream error:", err);
},
},
queuingStrategy,
);
const size = queuingStrategy.size(chunk);
console.log(`highWaterMark value: ${queuingStrategy.highWaterMark}$`);
