I've built an express application which people can upload images to server (files are parsing by multer module). I want to send an alert that says "Files are successfully uploaded" when the files are uploaded. I don't want to redirect user and then show the alert.
I couldn't find any solution for that.
var express = require("express");
var bodyParser = require("body-parser");
var multer = require('multer');
var app = express();
app.use(bodyParser.json());
var storage = multer.diskStorage({
destination: function (req, file, callback) {
callback(null, './images');
},
filename: function (req, file, callback) {
callback(null, file.fieldname + '-' + Date.now() + ".jpg");
}
});
var upload = multer({ storage: storage }).array('userPhoto', 5);
app.get('/', function (req, res) {
res.sendFile(__dirname + "/index.html");
});
app.post('/api/photo', function (req, res) {
upload(req, res, function (err) {
console.log(req.files)
});
});
app.listen(3000, function () {
console.log("Working on port 3000");
});<html>
