✨ NAME ✨

Plack::Loader — (auto)load Plack Servers 🎀

---

🌸 SYNOPSIS 🌸

# auto-select server backends based on env vars
use Plack::Loader;
Plack::Loader->auto(%args)->run($app);

# specify the implementation with a name
Plack::Loader->load('FCGI', %args)->run($app);

---

🦋 DESCRIPTION 🦋

so like… Plack::Loader is a factory class whose whole job is loading one of the Plack::Handler subclasses based on the environment. that's it, that's the gig. she reads the vibe check of your env and hands you the right handler. iconic behavior tbh 💅

---

👑 AUTOLOADING 👑

Plack::Loader->auto(%args) will autoload the most correct server implementation by guessing from environment variables and Perl INC hashes. she's literally out here sleuthing for you 🔍✨

---

💜 PLACK_SERVER

env PLACK_SERVER=AnyEvent ...

Plack users can specify the specific implementation they want to load using the PLACK_SERVER environment variable. just tell her which one you want and she delivers, periodt. 🫶

---

🍓 PHP_FCGI_CHILDREN, GATEWAY_INTERFACE

If there's one of FastCGI or CGI specific environment variables set, use the corresponding server implementation. she sees the FastCGI/CGI vibes and she's like "say less" 💀

---

🌈 %INC

If one of AnyEvent, Coro or POE is loaded, the relevant server implementation such as Twiggy, Corona or POE::Component::Server::PSGI will be loaded, if they're available. like she checks if your besties are in the group chat first — %INC tells her who's online 🧚

---

ngl bestie, the whole thing is just: guess the environment, pick the matching server backend, no drama. main character energy fr fr ⭐
