You can make use of BSON (Binary JSON) to store files in MongoDB collections. However, BSON has a limit of 16MB. If you are planning to store files bigger than that, consider GridFS

You can write files to MongoDB like so in Node.js:

var Binary = require(‘mongodb’).Binary;
//Read the file that you want to store
var file_data = fs.readFileSync(file_path);
var db_doc = {};
db_doc.file_data= Binary(file_data);

var my_collection = db.collection(‘files’);
my_collection.insert(db_doc, function(err, result){
//more code..
....
