Plack::...reaming(3)

💖 NAME 💖

Plack::Middleware::BufferedStreaming — bestie, this is the middleware that turns on buffering for servers that are not streaming aware ✨

(also hi, you're reading the User Contributed Perl Documentation version of this page, and it's giving very much "helpful friend energy" 🫶)

---

🌈 SYNOPSIS 🌈

enable "BufferedStreaming";

that's it. that's the whole vibe check. one line, no notes 💅

---

🦋 DESCRIPTION 🦋

okay so picture this: Plack::Middleware::BufferedStreaming is a PSGI middleware component and what it does is wrap your application — specifically an app that wants to use the psgi.streaming interface — and make it run on servers that do not support that interface 😭

how?? by buffering the writer output to a temporary buffer. that's the whole trick. iconic behavior honestly 🌸

but here's the thing, and it's important, so listen up: this middleware doesn't do anything and just bypasses the application entirely if the server does support the psgi.streaming interface — like, it minds its own business, it's not gonna insert itself into a situation that's already handled 🙈

...unless you set the force option (see below 👀). then it's got main character energy and shows up anyway.

---

✨ OPTIONS ✨

• force — force enable this middleware, but only if the container supports psgi.streaming. yeah, that's the whole option, and yeah, it's a specific little situation. no cap 🎀
