I have a function
function fileFilter(req, file, cb) {
if (file.mimetype !== 'image/png' && file.mimetype !== 'image/jpg' && file.mimetype !== 'image/gif' ) {
console.log('Wrong format!');
return cb(null, false);
}
if ( file.size > 10000 ){
console.log('Image is too big!');
return cb(null, false);
}
cb(null, true);
}
var upload = multer({ storage: storage, fileFilter: fileFilter });
This function works when I am making post request.
router.post('/changeAvatar', upload.single('avatar'), function(req, res) {
var id = req.user._id;
res.redirect('/user/'+id);
});
How can I put flash (connect-flash) instead off my console.log's?
Connect-flash is already installed, with cookies and sessions. I tried different ways, but I can't understand philosophy of flash messages...
first in your entry script you should use the connect flash middleware:
var express = require('express');
var session = require('express-session');
var cookieParser = require('cookie-parser');
var flash = require('connect-flash');
var app = express();
app.use(cookieParser('secret'));
app.use(session({cookie: { maxAge: 60000 }}));
app.use(flash());
then your function should look like :
function fileFilter(req, file, cb) {
if (file.mimetype !== 'image/png' && file.mimetype !== 'image/jpg' && file.mimetype !== 'image/gif' ) {
req.flash('error', 'Wrong format!');
return cb(null, false);
}
if ( file.size > 10000 ){
req.flash('error', 'Image is too big!');
return cb(null, false);
}
cb(null, true);
}
finally in '/user/'+id view you can get data from flash with :
JSON.stringify(req.flash('error'));
