# Formidable
|
||||
|
||||
[](http://travis-ci.org/felixge/node-formidable)
|
||||
|
||||
## Purpose
|
||||
|
||||
A node.js module for parsing form data, especially file uploads.
|
||||
|
||||
## Current status
|
||||
|
||||
This module was developed for [Transloadit](http://transloadit.com/), a service focused on uploading
|
||||
and encoding images and videos. It has been battle-tested against hundreds of GB of file uploads from
|
||||
a large variety of clients and is considered production-ready.
|
||||
|
||||
## Features
|
||||
|
||||
* Fast (~500mb/sec), non-buffering multipart parser
|
||||
* Automatically writing file uploads to disk
|
||||
* Low memory footprint
|
||||
* Graceful error handling
|
||||
* Very high test coverage
|
||||
|
||||
## Changelog
|
||||
|
||||
### v1.0.9
|
||||
|
||||
* Emit progress when content length header parsed (Tim Koschützki)
|
||||
* Fix Readme syntax due to GitHub changes (goob)
|
||||
* Replace references to old 'sys' module in Readme with 'util' (Peter Sugihara)
|
||||
|
||||
### v1.0.8
|
||||
|
||||
* Strip potentially unsafe characters when using `keepExtensions: true`.
|
||||
* Switch to utest / urun for testing
|
||||
* Add travis build
|
||||
|
||||
### v1.0.7
|
||||
|
||||
* Remove file from package that was causing problems when installing on windows. (#102)
|
||||
* Fix typos in Readme (Jason Davies).
|
||||
|
||||
### v1.0.6
|
||||
|
||||
* Do not default to the default to the field name for file uploads where
|
||||
filename="".
|

### v1.0.5
|
||||
|
||||
* Support filename="" in multipart parts
|
||||
* Explain unexpected end() errors in parser better
|
||||
|
||||
**Note:** Starting with this version, formidable emits 'file' events for empty

file input fields. Previously those were incorrectly emitted as regular file
|
||||
input fields with value = "".
|
||||

several architectural improvements.
|
||||
|
||||
[See Commits](https://github.com/felixge/node-formidable/compare/v0.9.11...v1.0.0)
|
||||
|
||||
### v0.9.11
|
||||
|
||||
* Emit `'progress'` event when receiving data, regardless of parsing it. (Tim Koschützki)
|
||||
* Use [W3C FileAPI Draft](http://dev.w3.org/2006/webapi/FileAPI/) properties for File class
|
||||
|
||||
**Important:** The old property names of the File class will be removed in a
|
||||
future release.

|
||||
## Installation
|
||||
|
||||
Via [npm](http://github.com/isaacs/npm):
|
||||
|
||||
npm install formidable@latest
|
||||
|
||||
Manually:
|
||||
|
||||
git clone git://github.com/felixge/node-formidable.git formidable
|
||||
vim my.js
|
||||
# var formidable = require('./formidable');
|
||||
|
||||
Note: Formidable requires [gently](http://github.com/felixge/node-gently) to run the unit tests, but you won't need it for just using the library.
|
||||
|
||||
## Example
|
||||
|
||||
Parse an incoming file upload.
|
||||
|
||||
var formidable = require('formidable'),
|
||||
http = require('http'),
|
||||
|
||||
util = require('util');
|
||||
|
||||
http.createServer(function(req, res) {
|
||||
if (req.url == '/upload' && req.method.toLowerCase() == 'post') {
|
||||
// parse a file upload
|
||||
var form = new formidable.IncomingForm();
|
||||
form.parse(req, function(err, fields, files) {
|
||||
res.writeHead(200, {'content-type': 'text/plain'});
|
||||
res.write('received upload:\n\n');
|
||||
res.end(util.inspect({fields: fields, files: files}));
|
||||
});
|
||||
return;
|
||||
}
|
||||
|
||||
// show a file upload form
|
||||
res.writeHead(200, {'content-type': 'text/html'});
|
||||
res.end(
|
||||
'<form action="/upload" enctype="multipart/form-data" method="post">'+
|
||||
'<input type="text" name="title"><br>'+
|
||||
'<input type="file" name="upload" multiple="multiple"><br>'+
|
||||
'<input type="submit" value="Upload">'+
|
||||
'</form>'
|
||||
);
|
||||
}).listen(80);
|
||||
|
||||
## API
|
||||
|
||||
### formidable.IncomingForm
|
||||
|
||||
__new formidable.IncomingForm()__
|
||||
|
||||
Creates a new incoming form.
|
||||
|
||||
__incomingForm.encoding = 'utf-8'__
|
||||
|
||||
The encoding to use for incoming form fields.
|
||||
|
||||
__incomingForm.uploadDir = process.env.TMP || '/tmp' || process.cwd()__
|
||||
|
||||
The directory for placing file uploads in. You can move them later on using
|
||||
`fs.rename()`. The default directory is picked at module load time depending on
|
||||
the first existing directory from those listed above.
|
||||
|
||||
__incomingForm.keepExtensions = false__
|
||||
|
||||
If you want the files written to `incomingForm.uploadDir` to include the extensions of the original files, set this property to `true`.
|
||||
|
||||
__incomingForm.type__
|
||||
|
||||
Either 'multipart' or 'urlencoded' depending on the incoming request.
|
||||
|
||||
__incomingForm.maxFieldsSize = 2 * 1024 * 1024__
|
||||
|
||||
Limits the amount of memory a field (not file) can allocate in bytes.
|
||||
If this value is exceeded, an `'error'` event is emitted. The default
|
||||
size is 2MB.
|
||||
|
||||
__incomingForm.hash = false__
|
||||
|
||||
If you want checksums calculated for incoming files, set this to either `'sha1'` or `'md5'`.
|
||||
|
||||
__incomingForm.bytesReceived__
|
||||
|
||||
The amount of bytes received for this form so far.
|
||||
|
||||
__incomingForm.bytesExpected__
|
||||
|
||||
The expected number of bytes in this form.
|
||||
|
||||
__incomingForm.parse(request, [cb])__
|
||||
|
||||
Parses an incoming node.js `request` containing form data. If `cb` is provided, all fields an files are collected and passed to the callback:
|
||||
|
||||
incomingForm.parse(req, function(err, fields, files) {
|
||||
// ...
|
||||
});
|
||||
|
||||
__incomingForm.onPart(part)__
|
||||
|
||||
You may overwrite this method if you are interested in directly accessing the multipart stream. Doing so will disable any `'field'` / `'file'` events processing which would occur otherwise, making you fully responsible for handling the processing.
|
||||
|
||||
incomingForm.onPart = function(part) {
|
||||
part.addListener('data', function() {
|
||||
// ...
|
||||
});
|
||||
}
|
||||
|
||||
If you want to use formidable to only handle certain parts for you, you can do so:
|
||||
|
||||
incomingForm.onPart = function(part) {
|
||||
if (!part.filename) {
|
||||
// let formidable handle all non-file parts
|
||||
incomingForm.handlePart(part);
|
||||
}
|
||||
}
|
||||
|
||||
Check the code in this method for further inspiration.
|
||||
|
||||
__Event: 'progress' (bytesReceived, bytesExpected)__
|
||||
|
||||
Emitted after each incoming chunk of data that has been parsed. Can be used to roll your own progress bar.
|
||||
|
||||
__Event: 'field' (name, value)__
|
||||
|
||||
Emitted whenever a field / value pair has been received.
|
||||
|
||||
__Event: 'fileBegin' (name, file)__
|
||||
|
||||
Emitted whenever a new file is detected in the upload stream. Use this even if
|
||||
you want to stream the file to somewhere else while buffering the upload on
|
||||
the file system.
|
||||
|
||||
__Event: 'file' (name, file)__
|
||||
|
||||
Emitted whenever a field / file pair has been received. `file` is an instance of `File`.
|
||||
|
||||
__Event: 'error' (err)__
|
||||
|
||||
Emitted when there is an error processing the incoming form. A request that experiences an error is automatically paused, you will have to manually call `request.resume()` if you want the request to continue firing `'data'` events.
|
||||
|
||||
__Event: 'aborted'__
|
||||
|
||||
Emitted when the request was aborted by the user. Right now this can be due to a 'timeout' or 'close' event on the socket. In the future there will be a separate 'timeout' event (needs a change in the node core).
|
||||
|
||||
__Event: 'end' ()__
|
||||
|
||||
Emitted when the entire request has been received, and all contained files have finished flushing to disk. This is a great place for you to send your response.
|
||||
|
||||
### formidable.File
|
||||
|
||||
__file.size = 0__
|
||||
|
||||
The size of the uploaded file in bytes. If the file is still being uploaded (see `'fileBegin'` event), this property says how many bytes of the file have been written to disk yet.
|
||||
|
||||
__file.path = null__
|
||||
|
||||
The path this file is being written to. You can modify this in the `'fileBegin'` event in
|
||||
case you are unhappy with the way formidable generates a temporary path for your files.
|
||||
|
||||
__file.name = null__
|
||||
|
||||
The name this file had according to the uploading client.
|
||||
|
||||
__file.type = null__
|
||||
|
||||
The mime type of this file, according to the uploading client.
|
||||
|
||||
__file.lastModifiedDate = null__
|
||||
|
||||
A date object (or `null`) containing the time this file was last written to. Mostly
|
||||
here for compatibility with the [W3C File API Draft](http://dev.w3.org/2006/webapi/FileAPI/).
|
||||
|
||||
__file.hash = null__
|
||||
|
||||
If hash calculation was set, you can read the hex digest out of this var.
