'Array getting converted to ArrayBuffer and giving different behaviour for Blob creation
This is the result object returned for saving an image file in mongodb using mongoose
Case 1
The result.img.data object has a String attribute type and an Array attribute data and that is exactly what I get on the client side if I io.emit(event, result) using socket.io
Case 2
But if I io.emit(event, result.img) then on the client side the object img.data becomes an ArrayBuffer
Why is this happening?
In Case 1 if I create a Blob using new Blob(new Uint8Array(result.img.data.data)) I get a different Blob object and the image file is unviewable
But in Case 2 if I create a Blob using new Blob([img.data]) then a different Blob object is created and the file is viewable
Why is this behaviour happening?
How can I create a viewable image Blob with the Array instead of the ArrayBuffer?
