WritableStreamDefaultWriter.close()

The close() method of the WritableStreamDefaultWriter interface closes the associated writable stream.

The underlying sink will finish processing any previously-written chunks, before invoking the close behavior. During this time any further attempts to write will fail (without erroring the stream).

Syntax

close()

Parameters

None.

Return value

A Promise, which fulfills with the undefined if all remaining chunks were successfully written before the close, or rejects with an error if a problem was encountered during the process.

Exceptions

• TypeError
  • : The stream you are trying to close is not a WritableStream.
