How to upload a file using filesystem I/O in Mean app? - angularjs

Question

I am using fs for uploading a file in my web app but the console shows that the file has been saved to the desired location which I have entered but the file doesn't show up there.
The code is here:-
var fs = require('fs-extra');
var path = require('path');
module.exports.updatePhoto = function(req,res) {
var file = req.files.file;
var userId = req.body.userId;
console.log("User "+ userId +" is submitting ", file);
var uploadDate = new Date();
var tempPath = file.path;
var targetPath = path.join(__dirname, "../../uploads/" + userId + uploadDate +file.name);
var savePath = "/uploads/" + userId + uploadDate + file.name;
fs.rename(tempPath, targetPath,function(err){
if(err) {
console.log(err);
}
else {
User.findById(userId, function(err, userData){
var user = userData;
user.image = savePath;
user.save(function(err){
if(err) {
console.log("failed")
res.json({status: 500})
}
else {
console.log("saved");
res.json({status: 200})
}
})
})
}
})
};

Are you using connect-multiparty to get the file from Express? https://github.com/expressjs/connect-multiparty
I ended up loading the files to AWS. So the best I can offer is the code to do that. It is basically free for my usage and I use docker to rebuild my site so this make it more flexible.
My File.Js:
'use strict';
module.exports = function (app) {
/**
* Module dependencies.
*/
var auth = require('../config/auth'),
api = {},
multiparty = require('connect-multiparty'),
multipartyMiddleware = multiparty(),
path = require('path'),
uuid = require('node-uuid'),
fs = require('fs'),
S3FS = require('s3fs');
var s3fsImpl = new S3FS('FOLDER_NAME_ENTER_HERE', {
accessKeyId: process.env.AWS_ACCESS_KEY_ID,
secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY
});
/**
* Saves the logo file to the server
*/
api.uploadImage = function(req, res) {
// We are able to access req.files.file thanks to the multiparty middleware
var folder = req.params.folder;
var file = req.files.file;
var filename = uuid.v4() + path.extname(file.name);
var stream = fs.createReadStream(file.path);
s3fsImpl.writeFile(folder + '/' + filename, stream).then(function () {
fs.unlink(file.path, function (err) {
if (err) {
console.error(err);
}
});
return res.status(200).json({'fileName': filename, 'url': 'https://s3-us-west-2.amazonaws.com/AWS_FOLDER_ENTER_HERE' + folder + '/' + filename});
});
};
/**
* Routes
*/
app.route('/api/files/:folder/uploadImage')
.post(auth.jwtCheck, multipartyMiddleware, api.uploadImage);
};
