Crochet: Use Twisted Anywhere!¶
Crochet is an MIT-licensed library that makes it easier for blocking and threaded applications like Flask or Django to use the Twisted networking framework.
Here’s an example of a program using Crochet:
#!/usr/bin/python """ Download a web page in a blocking manner. """ from __future__ import print_function import sys from twisted.web.client import getPage from crochet import setup, wait_for_reactor setup() @wait_for_reactor def download_page(url): return getPage(url) # download_page() now behaves like a normal blocking function: print(download_page(sys.argv))
Run on the command line:
$ python blockingdownload.py http://google.com <!doctype html><html itemscope="itemscope" ... etc. ...
Notice that you get a completely blocking interface to Twisted and do not need to run the Twisted reactor, the event loop, yourself.
