Store images in a MongoDB database

Please see the GridFS docs for details on storing such binary data.

Support for your specific language should be linked to at the bottom of the screen.

"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.

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();
});

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.

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.

Can you store files in MongoDB?

Yes.

Should you store files in MongoDB?

No.

MongoDB is NOT a good place for storing files. If you want to store files, you should use storages like Amazon S3 or Google Could Storage.

The good practice is to store the files in a storage and then to just save the URL of the uploaded image in the MongoDB.
