socketify.py

socketify.py brings:

• WebSocket with pub/sub support
• Fast and realiable Http/Https
• Support for Windows, Linux and macOS Silicon & x64
• Support for PyPy3 and CPython

This project aims to bring high performance PyPy3 web development and will bring:

• Fetch like API powered by libuv
• Async file IO powered by libuv
• Full asyncio integration with libuv
• Full Http3 support
• HPy integration to better support CPython, PyPy and GraalPython

We created and adapt the full C API from uNetworking/uWebSockets and will integrate libuv powered fetch and file IO, this same C API is used by Bun

socketify is experimental software at the moment, but quickly heading towards its first release. Join Github Discussions for help and have a look at things that don’t work yet.

socketify.py vs japronto

People really want to compare with japronto, but this projects are not really comparable. Socketify is an active project and will be maintained over time with security updates and new features, japronto don't get any github updates since 2020 and don't get any src update since 2018, japronto don't support SSL, WebSockets, PyPy3, Windows or macOS Silicon, socketify will support Http3 and a lot more features.

And yes, we can be faster than japronto when all our features and goals are achieved, and we are probably faster than any current maintained solution out there.

uvloop

We don't use uvloop, because uvloop don't support Windows and PyPy3 at this moment, this can change in the future, but right now we want to implement our own libuv + asyncio solution, and a lot more.

CFFI vs Cython vs HPy

Cython performs really well on Python3 but really bad on PyPy3, CFFI are choosen for better support PyPy3 until we got our hands on an stable HPy integration.

Benchmarks

HTTP requests per second (Linux x64)

Runtime versions: PyPy3 7.3.9 and Python 3.10.7
Framework versions: gunicorn 20.1.0 + uvicorn 0.19.0, socketify alpha, gunicorn 20.1.0 + falcon 3.1.0, robyn 0.18.3
Tested with oha -c 40 -z 5s http://localhost:8000/ (1 run for warmup and 3 runs average for testing)
Source code in bench
Machine OS: Debian GNU/Linux bookworm/sid x86_64 Kernel: 6.0.0-2-amd64 CPU: Intel i7-7700HQ (8) @ 3.800GHz Memory: 32066MiB

Today socketify have about 30% performance hit due to workarounds between asyncio + libuv, so we will got even faster! See more info in this issue, Python3 and PyPy3 performance will improve when we migrate to HPy. In TechEmPower benchmarks we are faster than japronto in plaintext (about 1,300k req/s using PyPy3 without workaround and about 770k req/s with the current state vs 582k from japronto you can follow details in this discussion

Examples

Hello world app

from socketify import App

app = App()
app.get("/", lambda res, req: res.end("Hello World socketify from Python!"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

SSL version sample

from socketify import App, AppOptions

app = App(AppOptions(key_file_name="./misc/key.pem", cert_file_name="./misc/cert.pem", passphrase="1234"))
app.get("/", lambda res, req: res.end("Hello World socketify from Python!"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % config.port))
app.run()

WebSockets

from socketify import App, AppOptions, OpCode, CompressOptions

def ws_open(ws):
    print('A WebSocket got connected!')
    ws.send("Hello World!", OpCode.TEXT)

def ws_message(ws, message, opcode):
    #Ok is false if backpressure was built up, wait for drain
    ok = ws.send(message, opcode)
    
app = App()    
app.ws("/*", {
    'compression': CompressOptions.SHARED_COMPRESSOR,
    'max_payload_length': 16 * 1024 * 1024,
    'idle_timeout': 12,
    'open': ws_open,
    'message': ws_message,
    'drain': lambda ws: print('WebSocket backpressure: %i' % ws.get_buffered_amount()),
    'close': lambda ws, code, message: print('WebSocket closed')
})
app.any("/", lambda res,req: res.end("Nothing to see here!'"))
app.listen(3000, lambda config: print("Listening on port http://localhost:%d now\n" % (config.port)))
app.run()
