Update Sentry now includes built-in support for ASGI. (Based on this implementation.)

Please see the documentation at https://docs.sentry.io/platforms/python/asgi/

Or the source code implementation at https://github.com/getsentry/sentry-python/blob/master/sentry_sdk/integrations/asgi.py

As a result, this repository has now been placed in an "archived" state.

sentry-asgi

Sentry integration for ASGI frameworks.

Installation:

pip install sentry-asgi

Usage:

from sentry_asgi import SentryMiddleware
import sentry_sdk


sentry_sdk.init(dsn=...)

app = ...
app = SentryMiddleware(app)

Here's a more complete example, using Starlette:

import sentry_sdk
from sentry_asgi import SentryMiddleware

sentry_sdk.init(dsn=...)

app = Starlette()

@app.route("/")
def homepage(request):
    raise ValueError("nope")

app.add_middleware(SentryMiddleware)

Notes

Python version support

The Sentry SDK requires Python 3.7's contextvars support in order to properly tie messages and logging back to the request context that is added SentryMiddleware.

On 3.6 and below the SentryMiddleware will capture and log application exceptions just fine, but will not properly tie in logging, messages, or breadcrumbs for any code that runs within a threadpool executor or subtask.

ASGI frameworks should ensure that any thread pool executors preserve the contextvar context.

Endpoint information

It is recommended that frameworks populate an "endpoint" key in the ASGI scope, to indicate which view function or class should be logged by the middleware.
