express-formparse

An Express middleware that uses Formidable to parse incoming multi-part forms.

What are Express, Formidable, and this?

Express is a fast, unopinionated, minimalist web framework for Node.js.

Formidable is a Node.js module for parsing form data, especially file uploads.

So, express-formparse is something like a bridge between them, specifically an Express middleware implementation of Formidable.

Install

npm install express-formparse

How

var express = require('express');
var formparse = require('express-formparse');
 
var app = express();
 
app.use(formparse.parse({
    encoding: 'utf8',
    uploadDir: 'tmp_upload',
    keepExtensions: true,
    hash: 'md5',
    multiples: true,
    matching: [
        /^(?:\/api\/.+)/,
        '/user/profile/picture'
    ]
}));
 
app.post('/upload', function (req, res) {
  // req.body will contain the parsed form
});

formparse.parse([options])

The keys and values in options will be directly passed to the formidable IncomingForm. (See node-formidable API for reference) Options may also contain one key 'matching' which is an array with either Strings or RegExps that has to match the incoming forms request path.

Only requests having a multipart/form-data content-type will be parsed.
