Convert blob to PDF and save to S3 using AWS SDK










0















I am trying to convert a document file to PDF and upload to S3 using my browser.



The API i'm using to convert the file is returning a blob. How can i convert the blob to a PDF file and save it to S3?



Currently my code looks like this



function addFile(file) 
console.log("File!", file);

var fileName = Date.now().toString();
var albumPhotosKey = encodeURIComponent("files") + '/';

var photoKey = albumPhotosKey + fileName;
s3.upload(
Key: photoKey,
Body: file + ".pdf",
ACL: 'public-read'
, function(err, data)
if (err)
console.log(err);
return alert('There was an error uploading your photo: ', err.message);

alert('Successfully uploaded photo.');
);



I tried converting the blob to a file using this



var file = new File([blobData], "filename.pdf", type: "application/pdf", lastModified: Date.now());


and then passed the file to the addFile() function but it creates a file which contains [object File].pdf as it's content.



How can i create a PDF file with the blob contents?

    Blobs and Files tend to be interchangeable for most native js apis. No conversion is needed. And the blob is probably already in a pdf format again no conversion needed. Also Body is supposed to be any of Buffer, Typed Array, Blob, String, ReadableStream. It is not supposed to be the filename

    Are you starting out with a PDF file already? If not, then you'll have to use a library to generate a PDF. It's not as simple as just converting a BLOB.
