Display image as response from Express with Node.js API to Angularjs

I tried to save the image on server directory and saved it's path in mongodb. When client (Angularjs) request details , Express has to send an array of objects in which one object property will send the image and rest of the object properties are data. First i got the image path from mongodb, and read the image from server directory and appended it to the rest of the data and send the response. But the image is sent as buffer array and my html page is not able to display the image buffer array.

Here's code

Express code

var fs = require('fs');
//To view the cars
app.route('/cars/view')
   .get(function(req,res){

        rentalcars.find().toArray(function(err,docs){
            if(err){
                res.send([{found:false}]);
            }else{
                var data = [];
                data.push({found:true});
                for(var i=0;i<docs.length;i++){
                    docs[i].imagePath = fs.readFileSync('./assets/images/'+docs[i].imagePath);
                    data.push(docs[i]);
                }

                res.send(data);
            }
        });
});

Client Code

 <table>
  <tbody ng-repeat="car in home.cars">
    <tr>
      <img ng-src="data:image/JPEG;base64,{{car.imagePath.data}}">
      <td>{{car.carName}}<br/>Segment : {{car.segment}}<br/>Rent : ${{car.rentCost}} /day</td>
    </tr>
  </tbody>

</table>

Response i get through Express API call is as below

    [
  {
    "found": true
  },
  {
    "_id": "58564aacbd224fdd2b7ad527",
    "carName": "sai",
    "segment": "suv",
    "rentCost": "1000",
    "imagePath": {
      "type": "Buffer",
      "data": [
        255,
        216,
        255,........]
     }
   }
]

Where data is array of huge data, i didn't paste it completely. How to send the images from Express with Node.js API to Client.

Below is the code that saves the images to the server directory and saves it's path in mongodb.

var filepath ='';
    var storage = multer.diskStorage({ //multers disk storage settings
            destination: function (req, file, cb) {
                cb(null, './assets/images/');
            },
            filename: function (req, file, cb) {
                var datetimestamp = Date.now();
                filepath = file.fieldname + '-' + datetimestamp + '.' + file.originalname.split('.')[file.originalname.split('.').length -1];
                cb(null, filepath);

            }
        });

    var upload = multer({ //multer settings
                        storage: storage
                    }).single('file');

    //To add new cars
    app.route('/cars/add')
       .post(function(req,res){
        //upload images to server/assets/images/
        upload(req,res,function(err){
            if(err){
                 res.json({error_code:1,err_desc:err});
            }
            var doc = {
                carName : req.body.carname,
                segment : req.body.segment,
                rentCost : req.body.rentcost,
                imagePath : filepath
            }

            rentalcars.insert(doc,function(err,result){
                if(err){
                    res.json({error_code:1,err_desc:err});
                }else{
                    res.json({error_code:0,err_desc:null});
                }
            });
        });

    });
