Check the Browser compatibility table carefully before using this in production.
The releaseLock()
method of the ReadableStreamDefaultReader
interface releases the reader's lock on the stream.
If the associated stream is errored when the lock is released, the reader will appear errored in that same way subsequently; otherwise, the reader will appear closed.
A reader’s lock cannot be released while it still has a pending read request, i.e., if a promise returned by the reader’s ReadableStreamDefaultReader.read()
method has not finished. This will result in a TypeError
being thrown.
Syntax
readableStreamDefaultReaderInstance.releaseLock();
Parameters
None.
Return value
Void.
Exceptions
- TypeError
- The source object is not a
ReadableStreamDefaultReader
, or a read request is pending.
Examples
function fetchStream() { const reader = stream.getReader(); ... reader.releaseLock() ... }
