The abort() method of the WritableStreamDefaultWriter 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.
If the writer is active, the abort() method behaves the same as that for the associated stream (WritableStream.abort()). If not, it returns a rejected promise.
js
abort() abort(reason)
reason Optional
A string representing a human-readable reason for the abort.
A Promise, which fulfills with the value given in the reason parameter.
TypeError The stream you are trying to abort is not a WritableStream, or it is locked.
js
const writableStream = new WritableStream( { write(chunk) { // ... }, close() { // ... }, abort(err) { // ... }, }, queuingStrategy, ); // ... const writer = writableStream.getWriter(); // ... // abort the stream when desired writer.abort.then((reason) => { console.log(reason); });
