philiprehberger-api-timer

Drop-in ASGI/WSGI middleware for endpoint timing with Server-Timing headers.

Installation

pip install philiprehberger-api-timer

Usage

ASGI (FastAPI, Starlette)

from fastapi import FastAPI
from philiprehberger_api_timer import ASGITimerMiddleware

app = FastAPI()
app.add_middleware(ASGITimerMiddleware, slow_threshold_ms=500)

WSGI (Flask, Django)

from flask import Flask
from philiprehberger_api_timer import WSGITimerMiddleware

app = Flask(__name__)
app.wsgi_app = WSGITimerMiddleware(app.wsgi_app, slow_threshold_ms=500)

What It Does

• Adds Server-Timing header to every response (e.g., Server-Timing: total;dur=42.5)
• Logs a WARNING for requests exceeding the slow threshold
• Zero configuration required — just add the middleware
