Request: arrayBuffer() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.
Note: This feature is available in Web Workers.
The arrayBuffer() method of the Request interface
reads the request body and returns it as a promise that resolves with an ArrayBuffer.
Syntax
js
arrayBuffer()
Parameters
None.
Return value
A promise that resolves with an ArrayBuffer.
Exceptions
TypeError-
Thrown for one of the following reasons:
- The request body is disturbed or locked.
- There was an error decoding the body content (for example, because the
Content-Encodingheader is incorrect).
RangeError-
Thrown if there is a problem creating the associated
ArrayBuffer(for example, if the data size is too large).
Examples
js
const myArray = new Uint8Array(10);
const request = new Request("/myEndpoint", {
method: "POST",
body: myArray,
});
request.arrayBuffer().then((buffer) => {
// do something with the buffer sent in the request
});
