express-parse-multipart v1.1.2

Description

Middleware parses request body with multipart/form-data content type and prepares an array of objects which represent every file which is sent in request. On the server side you will be able to get that array from req.formData property (see an example below). Every array item will contain data property which is a Buffer.

Using

1. Make a simple Express.js server in index.js file:

   const app = require('express')();
   const parseMp = require('express-parse-multipart');
   
   app.post('/upload', parseMp, (req, res) => {
     console.log(req.formData);  // here is the target array of objects
     return res.send('Yay!');
   });
   
   app.listen(3000, () => console.log('Started on: http://localhost:3000'));

2. Run it:

   node index.js

3. Make a POST request using any tool you want and send any file (-s) on http://localhost:3000/upload route. Check console to see the parsed result.
