A server for multi-user real-time webapps, using Python and Tornado.
Tornado is a python webserver for high-speed asynchronous networking.
In this talk we will primarily be making use of:
-
the basic tornado web framework, tornado.web: http://www.tornadoweb.org/en/stable/web.html
-
websockets! tornado.websocket: http://www.tornadoweb.org/en/stable/websocket.html
-
the main tornado IO loop, tornado.ioloop: http://www.tornadoweb.org/en/stable/ioloop.html
You can install tornado from PyPI using "pip"
pip install tornado
or for Python 3:
pip3 install tornado
Alternatively your package management system may have it, for example in Ubuntu 16.04 it can be installed via "apt":
sudo apt install python-tornado (Python 2)
sudo apt install python3-tornado (Python 3)
The client-side part of our code will be mostly written using HTML5, CSS, and Javascript.
Full client code is provided for each step, so knowledge of these languages is not necessary for this talk.
Full example code for each stage of the talk is given in numbered directories, "0", "1", "2", etc.
Each directory contains:
- server.py - the main python webserver
- client/index.html - the browser-based client
- client/* - any other resources used by the client
The webapp can be run by starting server.py.
It will listen on port 8888 by default,
but this can easily be changed.
Once the server is running,
connect to localhost:8888 using your favourite web browser.
In order for websockets to work when testing on your local machine, some browser security features may need to be disabled.
To connect to someone else's app on your local network, some operating system security features may need to be disabled.
