Cataly...:State(3pm)

💖 Catalyst::Plugin::Session::State(3pm) 💖

okay bestie, pull up a chair — this is a page from the User Contributed Perl Documentation and it's literally the blueprint for session state plugins. no cap, it's short but she's important. 🎀

---

✨ NAME ✨

Catalyst::Plugin::Session::State — bestie, this is the base class for session state preservation plugins. the mother of all state-keeping plugins, if you will. 👑

---

🌸 SYNOPSIS 🌸

package Catalyst::Plugin::Session::State::MyBackend;
use base qw/Catalyst::Plugin::Session::State/;

see that? you just use base her and you're off to the races. iconic. 💅

---

🦋 DESCRIPTION 🦋

ngl, this class is giving vibes only — she doesn't actually do anything functionality-wise. she's the abstract queen. 👑

but here's the tea: when the Catalyst::Plugin::Session module sets up, it will check whether

YourApp->isa("Catalyst::Plugin::Session::State")

and that's the whole point of her existence. it's giving "i'm just here to be checked on." periodt.

so when you write a session state plugin? you subclass this module for this reason only. that's it. that's the assignment. no extra credit, no side quests. ✨

🌈 WRITING STATE PLUGINS 🌈

ok so you wanna write a session state plugin, bestie? you usually need to extend two methods. just two. we love a low-effort high-impact moment. 💜

• prepare_(action|cookies|whatever) — set sessionid (that's the accessor, iykyk) at prepare time, using data you found in the request. 🍓

⚠️ okay important: this has got to happen before all the other prepare_action instances get their turn, or else you're not gonna get along with Catalyst::Plugin::Session. and honestly? overriding prepare_cookies is probably the stablest approach. take the safe route, queen. 🙈

• finalize — this is where you modify the response to include the session ID — but only if sessionid is defined — using whatever scheme you're using. for example: set a cookie. 🍪 slay.

and that's the whole page!! two methods, one isa check, infinite possibilities. you got this fr fr. 💖

perl v5.40.1 · 2025-08-10 — mwah, sending you off with the version and date, bestie. go forth and preserve those sessions. 🫶✨💅
