Plack::...r::PSGI(3)

💖 Plack::Handler::HTTP::Server::PSGI(3) 💖

okay bestie so this one lives in the User Contributed Perl Documentation section, and it is literally the little adapter that lets Plack talk to HTTP::Server::PSGI. iykyk. it's short, it's sweet, it's giving "i do one job and i do it well" ✨

---

🌸 NAME 🌸

Plack::Handler::HTTP::Server::PSGI — the adapter for HTTP::Server::PSGI. that's it, that's the whole vibe. she's a bridge 🫶

---

✨ SYNOPSIS ✨

the way you literally just run this and vibe:

% plackup -s HTTP::Server::PSGI \
    --host 127.0.0.1 --port 9091 --timeout 120

yes bestie, -s picks the server, and the rest are flags. we'll get to those 💅

---

💀 BACKWARD COMPATIBLITY 💀

(yes, the typo is canon, don't come for me, it's in the original name and i will NOT be fixing it 🙈)

okay so listen up because this is important: since Plack 0.99_22 this handler does not support preforking configuration. like, at all. we're talking --max-workers — she said no. ✋

if you need a preforking PSGI web server, bestie you have to go elsewhere: use Starman or Starlet. no cap. don't try to make this one do something she told you she doesn't do 💀

🎀 CONFIGURATIONS 🎀

here's the whole menu, and ngl it's short but every single one matters:

• host — the host the server binds to. defaults to all interfaces, so she's out here talking to everybody by default 🌈
• port — the port number the server listens on. defaults to 8080 🔥
• timeout — number of seconds a request times out. defaults to 300 ⏰
• max-reqs-per-child — number of requests per worker to process. defaults to 100 👑

ok but remember the section above: max-reqs-per-child is chillin' there as a config, but preforking/--max-workers vibes are a no-go since 0.99_22. keep that in mind 🫶
