express-formidable-reacteur v1.0.2

express-formidable-reacteur

An Express middleware of Formidable that just works.

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, including multipart/form-data file upload.

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

It aims to just work.

Install

npm install express-formidable-reacteur

How to use

const express = require("express");
const formidableMiddleware = require("express-formidable-reacteur");

var app = express();

app.use(formidableMiddleware());

app.post("/upload", (req, res) => {
  req.fields; // contains non-file fields
  req.files; // contains files
});

And that's it.

express-formidable can basically parse form types Formidable can handle, including application/x-www-form-urlencoded, application/json, and multipart/form-data.

Option

app.use(formidableMiddleware(opts));

opts are options which can be set to form in Formidable. For example:

app.use(formidableMiddleware({
  encoding: 'utf-8',
  uploadDir: '/my/dir',
  multiples: true, // req.files to be arrays of files
});

For the detail, please refer to the Formidable API.

Events

app.use(formidableMiddleware(opts, events));

events is an array of json with two field:

For example:

const events = [
  {
    event: "fileBegin",
    action: function (req, res, next, name, file) {
      /* your callback */
    },
  },
  {
    event: "field",
    action: function (req, res, next, name, value) {
      /* your callback */
    },
  },
];

Error event

Unless an error event are provided by the events array parameter, it will handle by the standard next(error).
