The closed getter property of the ReadableStream interface returns a promise that fulfills if the stream becomes closed or the reader's lock is released, or rejects if the stream errors.

Syntax

var closed = readableStreamDefaultReaderInstance.closed;

Value

A Promise.

Examples

In this snippet, a previously-created reader is queried to see if the stream has been closed. When it is closed, the promise fulfills and the message is logged to the console.

reader.closed.then(() => {
  console.log('reader closed');
})
