starlettecontext 0.3.6

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.

Dependencies

starlette

Example
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
{
"X-Correlation-ID":"5ca2f0b43115461bad07ccae5976a990",
"X-Request-ID":"21f8d52208ec44948d152dc49a713fdd"
}
Context can be updated and accessed at anytime if it’s created in the
middleware.
