• Fix: default url param in app.start by @sansyrox in #160

Full Changelog: v0.12.0...v0.12.1

app.startup_handler(startup_handler)

@app.shutdown_handler
def shutdown_handler():
    logger.log(logging.INFO, "Shutting down")

v0.11.1 - Make Robyn work with docker containers

This is a minor release. An input statement was being used instead of a print statement. This will help with docker containers and also Tech-Empowered benchmarking.

What's Changed

• Use print instead of input after starting server by @klaa97 in #149

New Contributors

• @klaa97 made their first contribution in #149

Full Changelog: v0.11.0...v0.11.1

Special thanks to @klaa97 for identifying the bug and fixing it! 🥳

v0.11.0 - Add support for query params across EVERY HTTP method and dev server fix

What's Changed

• Add project-wide flake8 settings by @sansyrox in #143
• URL queries by @patchgamestudio in #146
• Fix dev server by @sansyrox in #148

New Contributors

• @patchgamestudio made their first contribution in #146

Full Changelog: v0.10.0...v0.11.0

Summary

You can make a request to http://localhost:5000/query?a=b and can access the params in the following way:

@app.get("/query")
async def query_get(request):
    query_data = request["queries"]
    return jsonify(query_data)

The hot reloading server is now fixed and works on Linux and OSX(i.e. on all important operating systems). Windows support for dev server is still WIP.

Special thanks to @patchgamestudio for their contribution with the query params 🥳

v0.10.0 - Async Functions now supported in Web Sockets

The latest version of Robyn supports async functions in WebSockets now!

Usage

@websocket.on("message")
async def connect():
    global i
    i+=1
    if i==0:
        return "Whaaat??"
    elif i==1:
        return "Whooo??"
    elif i==2:
        return "*chika* *chika* Slim Shady."
    elif i==3:
        i= -1
        return ""

@websocket.on("close")
async def close():
    return "Goodbye world, from ws"

@websocket.on("connect")
async def message():
    return "Hello world, from ws"

Important Note:

Async functions execute out of order. i.e. They do not block the actor in order to provide concurrent execution. However, if the order is essential for you while using async functions, try using sync functions for now or wait for a future release :D

Websocket Intergration

PR Links

• Web socket integration attempt 2 by @sansyrox in #109

Full Changelog: v0.8.0...v0.9.0

Robyn supports WebSockets now.

from robyn import Robyn, WS

app = Robyn(__file__)
websocket = WS(app, "/web_socket")
i = -1

@websocket.on("message")
def connect():
    global i
    i+=1
    if i==0:
        return "Whaaat??"
    elif i==1:
        return "Whooo??"
    elif i==2:
        i = -1
        return "*chika* *chika* Slim Shady."
        
@websocket.on("close")
def close():
    print("Hello world")
    return "Hello world, from ws"

@websocket.on("connect")
def message():
    print("Hello world")

"message", "close" and "connect" for responding to the message received, connection closed and connection initiated.

Conclusion

It saves around 27 seconds under high strain conditions. The default configs are at 1 worker and 1 process. You can config for whatever works best for you.
