Chuyển đổi base64 to BlobUrl là xong

export function base64ToBlobUrl({
  base64String,
  contentType,
}: {
  base64String: string;
  contentType: string;
}) {
  if (includes(base64String, "base64")) {
    const parts = base64String?.split(";base64,");
    const type = parts[0]?.split(":")[1];
    const b64Data = parts[1];

    // Convert the base64 string to a Uint8Array
    const byteCharacters = atob(b64Data);
    const byteNumbers = new Array(byteCharacters.length);
    for (let i = 0; i < byteCharacters.length; i++) {
      byteNumbers[i] = byteCharacters.charCodeAt(i);
    }
    const byteArray = new Uint8Array(byteNumbers);

    // Create a Blob object from the binary data
    const blob = new Blob([byteArray], { type: contentType || type });

    // Create a URL for the Blob object
    const blobUrl = URL.createObjectURL(blob);

    return blobUrl;
  }
}
