Plack::...leLogger(3)

💖 Plack::Middleware::SimpleLogger 💖

okay so bestie, welcome to the Plack::...leLogger(3) page — it's from the User Contributed Perl Documentation collection, and it's literally about one million times shorter than it sounds. we're doing a vibes-only tour of a middleware that just... logs stuff. that's it. that's the whole girl. 🎀

✨ NAME ✨

Plack::Middleware::SimpleLogger — a SimpleLogger that prints to psgi.errors. no cap.

---

🌸 SYNOPSIS 🌸

look at her. one line. iconic behavior:

enable "SimpleLogger", level => "warn";

---

🦋 DESCRIPTION 🦋

so SimpleLogger is a middleware component — think of it like a lil accessory your app puts on before it goes out 💅 — and what it does is format the log message with extra info like the time and the PID 🕐🪪, and then it prints all of that to the psgi.errors stream.

and what is psgi.errors?? it's mostly STDERR, or the server's log output. so basically, wherever your server is already yelling into the void, that's where this goes. fr fr. 😌

---

💜 SEE ALSO 💜

• Plack::Middleware::LogErrors — which is, and I quote, essentially the opposite of this module. so if this one is the «we log it» girlie, that one is the «we turn it into errors» girlie. two sides of the same coin, we love a duality moment 🔥
