Sanic: app.websocket decorator doesn't exist

[Julien00859]

I've got a weird error:

$ cat tmp.py 
from sanic import Sanic
import websockets

app = Sanic()

@app.websocket("/ws")
async def ws(req, ws):
    while True:
        data = await ws.recv()
        print(data)
        await ws.send(data)

app.run(host="localhost", port=8080)

$ python3.6 tmp.py 
Traceback (most recent call last):
  File "tmp.py", line 6, in <module>
    @app.websocket("/ws")
AttributeError: 'Sanic' object has no attribute 'websocket'

I've looked at the doc and in the source code, I don't understand why it doesn't work. I'm using version 0.4.1. Are websockets available on a newer version not yet on PyPi ?

Correct - there is no websocket release yet. Look at the latest tag when browsing.

https://github.com/channelcat/sanic/tree/0.4.1

[d0ugal]

Or read the stable docs. http://sanic.readthedocs.io/en/stable/

i think the websocket feature will be available at version 0.5.0
https://github.com/channelcat/sanic/milestone/6?closed=1

but you can still use the latest version by installing from github.

pip install git+https://github.com/channelcat/sanic.git

Thanks !

[d0ugal]

but, of course, you should prefer the stable release I think :smile:

[d0ugal]

Does anyone happen to know the timeline for 0.5? I've been trying out the websockets in master and it has been excellent so far.

Waiting for #472

oh, thanks - I didn't think to check for milestones. Sorry for the extra noise.
