Installation

~~~~~~~~~~~~

Python ~3.7.0

.. code-block:: console

   $ pip install starlette-context==0.3.5

Python ^3.8

.. code-block:: console

   $ pip install starlette-context>=0.3.6

Dependencies

~~~~~~~~~~~~

-  ``starlette``

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.
