Converting Blob to File in Electron: A step-by-step guide

Is there a way to convert a Blob into a File object in ElectronJS? I attempted the following:

return new File([blob], fileName, {lastModified: new Date().getTime(), type: blob.type});

However, it appears that ElectronJs handles the File object differently:

ElectronJs File function:

Chrome Browser File function

I also tried:

(blob as any).name = fileName;
(blob as any).lastModified = new Date().getTime();
return blob as File;

Unfortunately, this approach did not yield the desired result.

Answer №1

I stumbled upon this workout routine:

convertBlobToFile(blob: Blob, filename: string) {
    const formData = new FormData();
    formData.set('bar', blob, filename);
    return formData.get('bar') as File;
}
