Blob
Blob is an interface that represents a blob, which is a file-like object of immutable, raw data; they can be read as text or binary data, or converted into a
ReadableStream.
It’s the type of the data received on
WebSocket.onmessage when WebSocket.binaryType is set to "blob".
A Blob instance has the following methods/properties:
| Class/Property | Description |
|---|---|
| Blob.size | The number of bytes of data contained within the Blob. |
| Blob.type | A string containing the MIME type, or an empty string if the type could not be determined. |
| Blob.arrayBuffer() | Returns a Promise that resolves with the contents of the blob as binary data contained in an ArrayBuffer. |
| Blob.bytes() | Returns a Promise that resolves with a Uint8Array containing the contents of the blob as an array of bytes. |
| Blob.slice() | Returns a new Blob object which contains data from a subset of the blob on which it’s called. |
| Blob.stream() | Returns a
ReadableStream which upon reading returns the data contained within the Blob. |
| Blob.text() | Returns a Promise that resolves with a string containing the contents of the blob, interpreted as UTF-8. |
