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) { 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 let sampleFile = req.files.sampleFile; // Use the mv() method to place the file somewhere on your server sampleFile.mv('/somewhere/on/your/server/filename.jpg', 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); });
