# ASGI middleware is ASGI v3 compliant. It can integrate with any
# ASGIv3-compliant applications.
# This example demonstrates Rollbar integration with the Starlette app.
#
# NOTE: Rollbar provides dedicated framework integrations that are more
# feature-rich. Currently available: Starlette and FastAPI.
#
# This example uses Uvicorn package that must be installed. However, it can be
# replaced with any other ASGI-compliant server.
#
# Optional asynchronous reporting requires HTTPX package to be installed.
#
# Run: python app.py
