express fileupload package problem with the path

Question

I'm encountering a problem when I want to upload a file to 'public' folder. This problem occurs when I don't use './'. if I use '../' or '/' files do not upload to the public folder.

**controllers.js**
files.forEach(file => {
        file.mv('../public/' + file.name, err => {
            if (err) {
                log({ err });
                return res.redirect('/')
            }

            log('file uploaded');

        })
    })

Error: Error: ENOENT: no such file or directory, open 'D:\Users\Antonio\Desktop\public\image4.jpg'

And also this error: Express-file-upload: Request is not eligible for file upload!

This happens when I'm inside controllers/controllers.js. If I write this code inside app.js, I do not face any issues.

Answer 1

The file.mv() method works relative to the cwd current working directory path.

To let it work, you need to write like:

const path = require('path')

const fileName = path.join(__dirname, '../public/', file.name)

file.mv(fileName)

By doing so, the path will be relative to the controller.js file (and not relative to the cwd)
