Change log
2.0.0 (2021-06-21)
As of this release, Safir is a helper library for FastAPI applications instead of aiohttp applications. Much of the library has changed. Authors of software that uses Safir should read the documentation again as part of the upgrade to FastAPI.
Included in this release is:
A FastAPI dependency to provide a structlog logger as configured by the safir.logging package, replacing the aiohttp middleware.
A FastAPI dependency to provide a global httpx.AsyncClient, replacing the middleware that provided an aiohttp client.
Starlette (FastAPI) middleware to parse X-Forwarded-* headers and update request information accordingly.
safir.metadata.get_metadata now returns a Pydantic model.
As of this release, Safir only supports Python 3.8 or later.
1.0.0 (2021-06-18)
Safir v1 will be the major release supporting aiohttp. Starting with Safir v2, Safir will become a support library for FastAPI applications.
This release has no significant difference from 0.2.0. The version bump is to indicate that the aiohttp support is stable.
0.2.0 (2021-06-10)
configure_logging now supports an optional add_timestamp parameter (false by default) that adds a timestamp to each log message.
Update dependencies.
0.1.1 (2021-01-14)
Fix duplicated log output when logging is configured multiple times.
Update dependencies.
0.1.0 (2020-02-26)
The first release of Safir featuring:
safir.http for adding an aiohttp.ClientSession to your application.
safir.logging for configuring structlog loggers.
safir.metadata helps your gather and structure metadata about your application for publishing on metadata endpoints.
safir.middleware includes a logging middleware that adds a logger with bound context about the request to your Request object.
Documentation about these features and a tutorial for starting a new application with the roundtable_aiohttp_bot template.
