Download a file from NodeJS Server using Express

Question

How can I download a file that is in my server to my machine accessing a page in a nodeJS server?

I\'m using the ExpressJS and I\'ve been trying this:

Answer 1

Use res.download()

It transfers the file at path as an “attachment”. For instance:

var express = require('express');
var router = express.Router();

// ...

router.get('/:id/download', function (req, res, next) {
    var filePath = "/my/file/path/..."; // Or format the path using the `id` rest param
    var fileName = "report.pdf"; // The default name the browser will use

    res.download(filePath, fileName);    
});
