uvloop is a fast, drop-in replacement of the built-in asyncio event loop. uvloop is implemented in Cython and uses libuv under the hood.

The project documentation can be found here.

Installation

uvloop requires Python 3.5 and is available on PyPI. Use pip to install it:

$ pip install uvloop

Using uvloop

To make asyncio use uvloop, you can install the uvloop event loop policy:

import asyncio
import uvloop
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())

Or, alternatively, you can create an instance of the loop manually, using:

loop = uvloop.new_event_loop()
asyncio.set_event_loop(loop)

Development of uvloop

To build uvloop, you'll need Cython and Python 3.5. The best way is to create a virtual env, so that you'll have cython and python commands pointing to the correct tools.

1. git clone --recursive [email protected]:MagicStack/uvloop.git
2. cd uvloop
3. make
4. make test
