Chai Theory — Indian Café

Five scenes, one scroll, one continuous pour

A cinematic café site whose hero is a five-scene film driven entirely by scroll position. A single ScrollTrigger produces one progress value and every layer — the floating kulhad, the pour, the letter-by-letter title, the chai surface expanding into the screen — is a pure function of that number, written straight to the DOM with no React state, so the whole sequence runs at 60fps with zero re-renders. The 520vh stage is deliberate: the scrollable range is height minus one viewport, so a shorter section would resolve the entire film in about a second of scrolling. Every beat is re-timed from one constants file, and appending ?p=0.45 freezes the hero at any point for tuning.

How to run this

Works the same on Windows, macOS and Linux. No prior setup beyond Node.js, and nothing to configure — the pack runs as-is.

Built with: Next.js 16
Requires: Node.js 20 or newer
Opens at: http://localhost:3000

✦ Or let an AI agent set it up for you

Already using Claude Code, Antigravity, Cursor or Windsurf? Unzip the pack, open the folder as a project, and just ask:

Install the dependencies and run this project, then give me the URL

It reads the README included in the pack, runs the right commands for this project, and sorts out anything that trips along the way. You still need Node.js installed (step 1 below) — everything after that it can handle.

Or run it yourself

1
Install Node.js, if you don't have it
Download the LTS build from nodejs.org and run the installer — on Windows and Mac it handles everything. Mac users with Homebrew can run brew install node instead.
To check it worked, run node --version. It should print a number like v22.11.0.
2
Unzip the pack, then open a terminal inside the folder
Windows: open the unzipped folder in File Explorer, click the address bar, type powershell and press Enter.
Mac: press Cmd+Space, type terminal, press Enter. Then type cd (with a trailing space) and drag the unzipped folder onto the terminal window — it fills in the path for you. Press Enter.
3
Install the dependencies
Run npm install
One-time, and takes roughly 30–60 seconds. It creates a node_modules folder — that's expected, and it's why the zip doesn't ship one.
4
Start it
Run npm run dev
Then open http://localhost:3000 in your browser. Leave the terminal open while you use it — closing it stops the site. Press Ctrl+C in the terminal to stop.
5
Optional — build for production
When you're ready to deploy, npm run build produces the optimised output. The pack deploys to Vercel, Netlify or any Node host with no changes.

+ If something goes wrong

“npm is not recognised” / “command not found: npm”: Node.js isn’t installed, or the terminal was open before you installed it. Close the terminal, open a new one, and try again.
“Port 3000 is already in use”: Something else is running there — often a previous copy of this site. Close the other terminal, or stop it with Ctrl+C.
The page loads but images or video are missing: Make sure you ran the command from inside the unzipped Chai Theory — Indian Café folder itself, not the folder containing it.
npm install shows warnings: Warnings (as opposed to errors) are normal and safe to ignore. Only a message starting with ERR! needs attention.
