Your node.js code:
```javascript
const express = require('express');
const fileUpload = require('express-fileupload');
const app = express();
// default options
app.use(fileUpload());
app.post('/upload', function(req, res) {
let sampleFile;
let uploadPath;
if (!req.files || Object.keys(req.files).length === 0) {
return res.status(400).send('No files were uploaded.');
}
// The name of the input field (i.e. "sampleFile") is used to retrieve the uploaded file
sampleFile = req.files.sampleFile;
uploadPath = __dirname + '/somewhere/on/your/server/' + sampleFile.name;
// Use the mv() method to place the file somewhere on your server
sampleFile.mv(uploadPath, function(err) {
if (err)
return res.status(500).send(err);
res.send('File uploaded!');
});
});
```
Your HTML file upload form:html <html> <body> <form ref='uploadForm' id='uploadForm' action='http://localhost:8000/upload' method='post' encType="multipart/form-data"> <input type="file" name="sampleFile" /> <input type='submit' value='Upload!' /> </form> </body> </html>
express-fileupload supports multiple file uploads at the same time.
Let's say you have three files in your form, each of the inputs with the name my_profile_pic, my_pet, and my_cover_photo:html <input type="file" name="my_profile_pic" /> <input type="file" name="my_pet" /> <input type="file" name="my_cover_photo" />
These uploaded files would be accessible like so:javascript app.post('/upload', function(req, res) { // Uploaded files: console.log(req.files.my_profile_pic.name); console.log(req.files.my_pet.name); console.log(req.files.my_cover_photo.name); });
