streaming_form_data provides a Python parser for parsing multipart/form-data input chunks (the encoding used when submitting data over HTTP through HTML forms).

Testimonials

"this speeds up file uploads to my Flask app by more than factor 10"

"Thanks a lot for your fix with streaming-form-data. I can finally upload gigabyte sized files at good speed and without memory filling up!"

Installation

$ pip install streaming-form-data

In case you prefer cloning the Github repository and installing manually, please note that master is the development branch, so stable is what you should be working with.

Usage

>>> from streaming_form_data import StreamingFormDataParser
>>> from streaming_form_data.targets import ValueTarget, FileTarget, NullTarget
>>>
>>> headers = {'Content-Type': 'multipart/form-data; boundary=boundary'}
>>>
>>> parser = StreamingFormDataParser(headers=headers)
>>>
>>> parser.register('name', ValueTarget())
>>> parser.register('file', FileTarget('/tmp/file.txt'))
>>> parser.register('discard-me', NullTarget())
>>>
>>> for chunk in request.body:
...     parser.data_received(chunk)
...
>>>

Documentation

Development

Please make sure you have Python 3.6+ and pip-tools installed.

Since this package includes a C extension, please make sure you have a working C compiler available. On Debian-based distros this usually means installing the build-essentials package.

  1. Git clone the repository: git clone https://github.com/siddhantgoel/streaming-form-data

  2. Install the packages required for development: make pip-sync

  3. That's basically it. You should now be able to run the test suite: make test.
