WritableStream: abort() method

Available in workers

The abort() method of the WritableStream interface aborts the stream, signaling that the producer can no longer successfully write to the stream and it is to be immediately moved to an error state, with any queued writes discarded.

Syntax

abort(reason)

Parameters

• reason
  • : A string providing a human-readable reason for the abort.

Return value

A Promise, which fulfills with undefined.

Exceptions

• TypeError
  • : The stream you are trying to abort is not a WritableStream, or it is locked.

Examples

const writableStream = new WritableStream(
  {
    write(chunk) {
      // …
    },
    close() {
      // …
    },
    abort(err) {
      // …
    },
  },
  queuingStrategy,
);

// …

// abort the stream later on, when required
writableStream.abort();
