How do I store binary data from post to MongoDB

Question

I have small images I want to store as a bin data item. The form is posted but I do not know what to do in the controller so that if I so this, the data is stored. I am using Sails.js and the form is passing data as "image" with the form having a file input type.

var image = new Images;
image.data = ????
image.save();

Answer 1

If the images are smaller than 16Mb, you can save them directly using MongoDB's bindata type. You can always convert the binary stream to a Base64 string, and store it as a string file, but that will reduce the allowed image size.

If the image is larger than 16Mb, you have no choice but to use GridFS.
