Node JS AWS S3 file upload. How to get public URL response

Question

I'm uploading a file to Amazon S3 using the Node SDK.

The file uploads are working fine, but I want to get the public url of the file to send back to the client.

At the moment the response I get is:

Successfully uploaded data { ETag: '"957cd1a335adf5b4000a5101ec1f52bf"' } 

Here is my code. I'm using a Node Express server, and Multer to handle uploads.

app.use(multer({ // https://github.com/expressjs/multer       dest: './public/uploads/',        limits : { fileSize:100000 },       rename: function (fieldname, filename) {         var time = new Date().getTime();         return filename.replace(/\W+/g, '-').toLowerCase() + time;       },       onFileUploadData: function (file, data, req, res) {         // file : { fieldname, originalname, name, encoding, mimetype, path, extension, size, truncated, buffer }         var params = {           Bucket: creds.awsBucket,           Key: file.name,           Body: data,           ACL: 'public-read'         };          var s3 = new aws.S3()         s3.putObject(params, function (perr, pres) {           if (perr) {             console.log("Error uploading data: ", perr);           } else {             console.log("Successfully uploaded data", pres);           }         });       }     }));      app.post('/upload-image', function(req, res){         if(req.files.file === undefined){             res.send("error, no file chosen");         }     });

Use upload instead of putObject. It will return public url in Location key
