"Including a profiler like pyinstrument in a production environment is dangerous, as it exposes infrastructure and poses significant risks to user data."
"The ProfileMiddleware class in FastHTML allows you to profile your application by using a GET parameter to trigger performance analysis with pyinstrument."
"To use the profiling middleware, simply add `?profile=1` to your request, and you'll receive an HTML report of your application's performance."
"FastHTML is built on Starlette, utilizing its middleware capabilities to enhance applications with profiling features."
FastHTML, built on Starlette, offers a ProfileMiddleware that profiles application performance using pyinstrument. This middleware can be invoked via a GET request parameter, `profile=1`, which triggers profiling and presents an HTML output. However, it is crucial to note that this middleware is strictly for development environments; using it in production is dangerous due to potential exposure of sensitive infrastructure details. Installation of the `pyinstrument` library is required prior to using the middleware, as it facilitates the performance tracking process.
