Plack::...::JSONP(3)

💖 Plack::Middleware::JSONP — bestie's guide to wrapping JSON in JSONP 💖

okay so real talk: this is Plack::Middleware::JSONP(3), straight out of the User Contributed Perl Documentation, and it's literally the glow-up your JSON API has been begging for. Wraps JSON response in JSONP if callback parameter is specified. That's the whole vibe. 🎀

✨ NAME ✨

Plack::Middleware::JSONP — wraps a JSON response in JSONP when the callback parameter shows up. no cap, that's it, that's the girl 🌸

---

🦋 SYNOPSIS 🦋

enable "JSONP", callback_key => 'jsonp';

one line. she's minimal, she's iconic, she ate 💅

🌈 DESCRIPTION 🌈

So here's the tea, bestie: Plack::Middleware::JSONP grabs a JSON response — and by "JSON response" we mean one whose Content-Type value is either text/javascript or application/json — and wraps it up as a JSONP response instead. Which one does it become? The one that's specified with the callback query parameter. ✨

And the way that you get to name that parameter yourself? You set it while enabling the middleware. Your middleware, your rules, your main character energy 👑

One (1) very important caveat though, and I need you to hear me on this: this middleware only works with a non-streaming response. Streaming? Not it. And other than that whole wrapping situation, it doesn't touch the response otherwise — it minds its own business, fr fr. 🫶
