# express-fileupload Examples
## Basic File Upload
**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>
```
## Multi-File Upload
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);
});
```
