Blob

A file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

class Blob {
constructor(blobParts?: BlobPart[], options?: BlobPropertyBag);
readonly size: number;
readonly type: string;
 
arrayBuffer(): Promise<ArrayBuffer>;
slice(
start?: number,
end?: number,
contentType?: string,
): Blob;
stream(): ReadableStream<Uint8Array>;
text(): Promise<string>;
}
