Blob: arrayBuffer() method - Web APIs

Blob: arrayBuffer() method

Baseline Widely available

Note: This feature is available in Web Workers.

The arrayBuffer() method of the Blob interface returns a Promise that resolves with the contents of the blob as binary data contained in an ArrayBuffer.

Syntax Parameters

None.

Return value

A promise that resolves with an ArrayBuffer that contains the blob's data in binary form.

Exceptions

While this method doesn't throw exceptions, it may reject the promise. This can happen, for example, if the reader used to fetch the blob's data throws an exception. Any exceptions thrown while getting the data will be converted into rejections.

Usage notes

While similar to the FileReader.readAsArrayBuffer() method, arrayBuffer() returns a promise rather than being an event-based API, as is the case with the FileReader interface's method.
