🔎 Upcoming Features

• In-Memory Cache Tools
• Fetch like API powered by libuv

📦 Installation

For macOS x64 & Silicon, Linux x64, Windows

pip install socketify
#or specify PyPy3
pypy3 -m pip install socketify
#or in editable mode
pypy3 -m pip install -e socketify

Using install via requirements.txt

socketify

pip install -r ./requirements.txt 
#or specify PyPy3
pypy3 -m pip install -r ./requirements.txt 

If you are using linux or macOS, you may need to install libuv and zlib in your system

macOS

brew install libuv
brew install zlib

Linux (Ubuntu/Debian)

apt install libuv1 zlib1g

Linux (RHEL/OEL)

yum install cmake zlib-devel libuv-devel

🤔 Usage

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, 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(f'WebSocket backpressure: {ws.get_buffered_amount()}'),
    'close': lambda ws, code, message: print('WebSocket closed'),
    'subscription': lambda ws, topic, subscriptions, subscriptions_before: print(f'subscribe/unsubscribe on topic {topic} {subscriptions} {subscriptions_before}'),
})
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()

❔ 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 chosen for better support PyPy3 until we got our hands on a stable HPy integration.
