Azure's Application insights for Starlette

This is a small module to use Azure's Application insights on a Starlette application.

How to use:

from starlette.applications import Starlette
from starlette.middleware.base import BaseHTTPMiddleware

app = Starlette()

from .appinsight import AppInsights
insights = AppInsights('<instrumentation_key>')

app.add_exception_handler(Exception, insights.exception_handler)

app.add_middleware(BaseHTTPMiddleware, dispatch=insights.request_middleware)
app.add_middleware(BaseHTTPMiddleware, dispatch=insights.flush_middleware)

# or any variation of how you log in your app
logging.getLogger(__name__).addHandler(insights.log_handler)


@app.route('/')
async def homepage(request):
    return JSONResponse({'hello': 'world'})

if __name__ == '__main__':
    uvicorn.run(app, host='0.0.0.0', port=8000)

At this point, any request, log message or exception will be pushed to Azure's application insights.
