Asynchronous framework

Primary LanguageJavaScriptOtherNOASSERTION

License PyPI version

Introduction.

This asynchronous framework with a modular structure like Django. But with mongodb, jinja2, websocket out of the box, and more than a simple barrier to entry.

Built on the basis of asyncio and aiohttp. In the framework, have batteries. The prototype of the game framework as a component.

###Requirements

Python >= 3.5.1
aiohttp
aiohttp_jinja2
aiohttp_session
aiohttp_debugtoolbar
aiomcache
pymongo

###Installation Python 3.5 for old version ubuntu

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.5 python3.5-dev 

###Installation dependencies

apt install gcc python3.5-dev build-essential libssl-dev libffi-dev libjpeg-dev libxslt1-dev libxml2-dev  python-pip

#Framework Installation

$ pip install tao1

##Getting Started

Create a project anywhere:

   utils.py -p name

Create an application in the folder of the project apps:

   utils.py -a name

Run server:

   python3 index.py

##License

It's MIT licensed and freely available.

##Deploy When you develop enough to run the file python3 index.py. For production to run index.py, is better to use the supervisor and nginx. Settings supervisor in /etc:

   [program:name]
   command=python3 index.py
   directory=/path/to/your/project
   user=nobody
   autorestart=true
   redirect_stderr=true

Settings nginx in /etc together with proxy websocket::

server {
        server_name        aio.dev;
         location / {
                 proxy_pass http://127.0.0.1:8080;
         }
        location /ws {
              proxy_pass http://127.0.0.1:8080;
              proxy_http_version 1.1;
              proxy_set_header Upgrade $http_upgrade;
              proxy_set_header Connection "upgrade";
       }
}

###Routes

Example route in file routes.py::

   from libs.game.game import  *
   from core.union import route
   
   route('GET', '/ws',  ws,	'ws' )

###Templates

In framework integrated jinja2. Templates are always in the templ folder.

To call the template function templ and pass it the template name. If the template is in some sort of module, the call looks like this libs.modul_name.templ_name.

If the template is in the root of the project in the templ folder, then simply write his name.

Example:

   def page(request):
       return templ('index', request, {'key':'val'} )

###Websockets

The websocket to create games and chat very easy to use.

The first is the need to call route with the template to draw the route and chat with the handler for chat:

   route('GET', '/ws',   ws,    'ws' )
   route('GET', '/wsh',  ws_handler, 'ws_handler' )

These routes work you can see an example.

The second is the functions themselves. Function for render chat page:

   async def ws(request):
       return templ('libs.app:chat', request, {} )

Function handler chat:

   async def ws_handler(request):
      ws = web.WebSocketResponse()
      await ws.prepare(request)
      async for msg in ws:
          if msg.tp == aiohttp.MsgType.text:
              if msg.data == 'close':
                  await ws.close()
              else:
                  ws.send_str(msg.data + '/answer')
          elif msg.tp == aiohttp.MsgType.error:
              print('ws connection closed with exception %s' % ws.exception())
      print('websocket connection closed')
      return ws

###Database

To write the database query you need to request.db and then as usual.

    async def test_db(request):
	    # save doc
	    request.db.doc.save({"_id":"test", "status":"success"})
	    # find doc
	    val = request.db.doc.find_one({"_id":"test"})
	    return templ('apps.app:db_test', request, {'key':val})

###Static files

Static files it is better to entrust nginx but tao1 able return files.

All files must be located in the folder static.

If they are the root of the project then the path will be like this /static/file_name.pg. If the files are in a certain module, then the path like this /static/module_name/file_name.jpg.

###Caching

Create cache for function 5 second, the first parameter - name::

   @cache("main_page", expire=5)
   async def page(request):
       return templ('index', request, {'key':'val'} )

#Game In this case, the game framework is a battery, the basic framework. The game is a 3D multiplayer shooting. Prototype game framework have multiplayer mode, the mini-map, rooms, bot, several typical models of tanks. The client side is written in the framework WEBGL babylon.js. ###Game start Game start is located on the route /pregame.
