OnePageParty: A privacy-first, no-login party toolkit. Built with Next.js App Router & Supabase

[lauraliang618]

Hi everyone! 👋

I wanted to share a project I've been working on as an indie developer: OnePageParty.

🤔 The Problem

Every time I organized a party, I was frustrated by the "bloat" in the current ecosystem.

• Recipe blogs are impossible to read (too many ads/stories just to find a quantity).
• Design tools (like Canva) force you to sign up/login just to print a simple "Happy Birthday" banner.

🛠 The Solution

I built a suite of "single-purpose" tools that require no login and no user data collection.

• Banner Maker: A canvas-based editor that generates print-ready PDFs entirely client-side.
• Party Calculators: Interactive logic to estimate Pizza/Taco/Cake quantities for crowds.

💻 The Tech Stack

I treated this project as an experiment in "Engineering as Marketing".

• 🛠️ Framework: Next.js 14 (App Router)
• 🎨 Styling: Tailwind CSS + shadcn/ui (for accessible, clean components)
• 💾 Backend: Supabase (for handling dynamic content where needed)
• 🚀 Deployment: Vercel

🚀 Performance

Since the goal was to be "lightweight," I focused heavily on Core Web Vitals. The site uses extensive static generation (SSG) for the landing pages to ensure near-instant loads.

I’d love to get your feedback on the UX or the implementation!

(P.S. If anyone is planning a Super Bowl party soon, the Pizza Calculator might actually save you some budget! 🍕)
