Почему мультер не определен?

Question

Почему multer после отправки формы всегда возвращает значение - не определено?

app.js

app.use('/post', routePost);

Контроллер:

var storage = multer.diskStorage({
destination: function (req, file, cb) {
    cb(null, './pubic/uploads')
},
filename: function (req, file, cb) {
    cb(null, file.fieldname + '-' + Date.now())
}

router.post('/create', upload.single('cover'), (req, res) => {
    console.log(req.file)
})

HTML:

<form action="/post/create" method="POST" enctype="multipart/form-data">
    <input id="cover" name="cover" type="file"  />
    <button type="submit">Save</button>
</form>

Answer 1

var storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './pubic/uploads')
},
filename: function (req, file, cb) {
cb(null, file.fieldname + '-' + Date.now())
}

const upload = multer({storage, limits: {fileSize: '2mb'},

router.post('/create', upload.single('cover'), (req, res) => {
console.log(req.file)
})
