starlette context

Middleware for Starlette that allows you to store and access the context data of a request. Can be used with logging so logs automatically use request headers such as x-request-id or x-correlation-id.

Example


.. code:: python

   import uvicorn

   from starlette.applications import Starlette
   from starlette.middleware import Middleware
   from starlette.requests import Request
   from starlette.responses import JSONResponse

   from starlette_context import context, plugins
   from starlette_context.middleware import RawContextMiddleware

   middleware = [
       Middleware(
           RawContextMiddleware,
           plugins=(
               plugins.RequestIdPlugin(),
               plugins.CorrelationIdPlugin()
           )
       )
   ]

   app = Starlette(middleware=middleware)


   @app.route("/")
   async def index(request: Request):
       return JSONResponse(context.data)


   uvicorn.run(app, host="0.0.0.0")

In this example the response contains a json with

.. code:: json

   {
     "X-Correlation-ID":"5ca2f0b43115461bad07ccae5976a990",
     "X-Request-ID":"21f8d52208ec44948d152dc49a713fdd"
   }

Context can be updated and accessed at anytime if it’s created in the
middleware.
