Simple Usage example

from webpet.application import ASGIApplication
from webpet.conf import Configuration
from webpet.response import HTTPResponse
from webpet.routers import HTTPRouter, URL
from webpet.views import View, LongPoolView, TemplateView

import asyncio
import json
import random
import os

BASE_DIR = os.getcwd() + '/'

class Index(TemplateView):
    template_name = 'index.html'


class Aboba(View):

    async def get(self):
        raise ValueError()


class TestLong(LongPoolView):

    async def get(self):
        await self.open(status_code=200, headers=[(b'Content-type', b'application/json')])
        data = []
        ticks = 0
        while True:
            ticks += 1
            number = random.randint(0, 1000)
            data.append(number)
            if number >= 500:
                await self.send(HTTPResponse(
                    json.dumps({
                        'data': data,
                        'ticks': ticks
                    })
                ))
                break
            else:
                await asyncio.sleep(1)


router = HTTPRouter(routes=[
    URL('/', Index),
    URL('/aboba', Aboba),
    URL('/longpool', TestLong)
])

configuration = Configuration()
configuration.router = router
configuration.templates_dir = BASE_DIR + 'templates/'

app = ASGIApplication()

To run with daphne use

pip install daphne
daphne <application_name>:<ASGIApplication instance>
