How to receive base64 data from Nodejs and display using jquery

I am using images or other times of files in my database as a blob. Once I retrieve that blob I put that in a buffer and convert to base64 like this:

file = Buffer.from(blob,'binary').toString('base64');
res.send(file)

Now, in my jquery :

On success after the post route is fired I want to receive the file:

 success: function(data){
        console.log(data)
        console.log('image uploaded and form submitted');     
      }

But the console.log shows that the entire file is just this: W29iamVjdCBPYmplY3Rd

From my understanding of buffer it is just a small memory allocation used to transfer large sets of data one at a time. So I think I am only getting the first buffer? How do I get the entire buffer?

W29iamVjdCBPYmplY3Rd is the base64 for [object Object]

You must check what the blob is actually, its not a string of data, its a javascript object, contains the whole row of the database, or something else.

The objects.toString() is called when passed into buffer.from

I would suggest using console.log(blob) and you will be happy.
