You can use the bin data type if you are using any scripting language to store files/images in MongoDB. Bin data is developed to store small size of files.
Refer to your scripting language driver. For PHP, click here.
You can try this one:
String newFileName = "my-image";
File imageFile = new File("/users/victor/images/image.png");
GridFS gfsPhoto = new GridFS(db, "photo");
GridFSInputFile gfsFile = gfsPhoto.createFile(imageFile);
gfsFile.setFilename(newFileName);
gfsFile.save();

There is a Mongoose plugin available on NPM called mongoose-file. It lets you add a file field to a Mongoose Schema for file upload. I have never used it but it might prove useful. If the images are very small you could Base64 encode them and save the string to the database.
Storing some small (under 1MB) files with MongoDB in NodeJS WITHOUT GridFS
install below libraries
var express = require(‘express’);
var fs = require(‘fs’);
var mongoose = require(‘mongoose’);
var Schema = mongoose.Schema;
var multer = require('multer');
connect ur mongo db :
mongoose.connect(‘url_here’);
Define database Schema
var Item = new ItemSchema({
img: {
data: Buffer,
contentType: String
}
}
);
var Item = mongoose.model('Clothes',ItemSchema);
using the middleware Multer to upload the photo on the server side.
app.use(multer({ dest: ‘./uploads/’,
rename: function (fieldname, filename) {
return filename;
},
}));
post req to our db
app.post(‘/api/photo’,function(req,res){
var newItem = new Item();
newItem.img.data = fs.readFileSync(req.files.userPhoto.path)
newItem.img.contentType = ‘image/png’;
newItem.save();
});
var upload = multer({dest: "./uploads"});
var mongo = require('mongodb');
var Grid = require("gridfs-stream");
Grid.mongo = mongo;
router.post('/:id', upload.array('photos', 200), function(req, res, next){
gfs = Grid(db);
var ss = req.files;
for(var j=0; j<ss.length; j++){
var originalName = ss[j].originalname;
var filename = ss[j].filename;
var writestream = gfs.createWriteStream({
filename: originalName
});
fs.createReadStream("./uploads/" + filename).pipe(writestream);
}
});
In your view:
<form action="/" method="post" enctype="multipart/form-data">
<input type="file" name="photos">
With this code you can add single as well as multiple images in MongoDB.
"You should always use GridFS for storing files larger than 16MB" - When should I use GridFS?
MongoDB BSON documents are capped at 16 MB. So if the total size of your array of files is less than that, you may store them directly in your document using the BinData data type.
Videos, images, PDFs, spreadsheets, etc. - it doesn't matter, they are all treated the same. It's up to your application to return an appropriate content type header to display them.
Check out the GridFS documentation for more details.
