VistasHow to display image in angular(image uploded in server side uploads folder and angularjs is working in different server)?
I uploaded image using multer,node.js,mongodb.
I uploaded the image in upload folder and I stored the path in MongoDB.
this is my folder structure
server is running
http://localhost:3000/images/590051dcc90cf702e452b9c1
based on document id I am retriving document
// To get the single image/File using id from the MongoDB
app.get('/images/:id', function(req, res) {
//calling the function from index.js class using routes object..
routes.getImageById(req.params.id, function(err, genres) {
if (err) {
throw err;
}
//res.download(genres.path);
res.send(genres)
});
});
I got response like this
{"_id":"590051dcc90cf702e452b9c1","path":"uploads\login.jpg","name":"asdf","email":"asdf@gmail.com","originalname":"login.jpg","__v":0}

On Node JS server convert the get api method to fetch the image path from Mongo Db and return the byte array of the image.
// To get the single image/File using id from the MongoDB
app.get('/images/:id', function(req, res) {
//calling the function from index.js class using routes object..
routes.getImageById(req.params.id, function(err, genres) {
if (err) {
throw err;
}
//res.download(genres.path);
var fs = require('fs');
// read binary data
var bitmap = fs.readFileSync(genres.path);
// convert binary data to base64 encoded string
//res.send(new Buffer(bitmap).toString('base64'));
genres.path = new Buffer(bitmap).toString('base64');
res.send(genres)
});
});
Bind this byte array to your tag.
<img ng-src="{{'data:image/png;charset=utf-8;base64,' + response.data.path}}">

Just assign the path to image using ng-src
Assume this is the response json
$scope.response = {"_id":"590051dcc90cf702e452b9c1","path":"uploads\login.jpg","name":"asdf","email":"asdf@gmail.com","originalname":"login.jpg","__v":0}
in the image tag.
<img ng-src"{{response.path}}">
0
You can use <img ng-src="{{response.path}}"/>
