Are you coder looking for a project to contribute to python/asyncio libraries? This is the project for you!
$ pip install aiohttp_debugtoolbar
In order to plug in aiohttp_debugtoolbar, call
aiohttp_debugtoolbar.setup on your app.
import aiohttp_debugtoolbar
app = web.Application(loop=loop)
aiohttp_debugtoolbar.setup(app)import asyncio
import jinja2
import aiohttp_debugtoolbar
import aiohttp_jinja2
from aiohttp import web
@aiohttp_jinja2.template('index.html')
async def basic_handler(request):
return {'title': 'example aiohttp_debugtoolbar!',
'text': 'Hello aiohttp_debugtoolbar!',
'app': request.app}
async def exception_handler(request):
raise NotImplementedError
async def init(loop):
# add aiohttp_debugtoolbar middleware to you application
app = web.Application(loop=loop)
# install aiohttp_debugtoolbar
aiohttp_debugtoolbar.setup(app)
template = """

<head>
<title>{{ title }}</title>
</head>
<body>

<p>
<a href="{{ app.router['exc_example'].url() }}">

</p>
</body>
</html>
"""
# install jinja2 templates
loader = jinja2.DictLoader({'index.html': template})
aiohttp_jinja2.setup(app, loader=loader)
# init routes for index page, and page with error
app.router.add_route('GET', '/', basic_handler, name='index')
app.router.add_route('GET', '/exc', exception_handler,
name='exc_example')
return app
