Code that reads well from the back row
Highlight lines one click at a time, morph one version into the next with magic move, or run the code on the slide in a Monaco editor.
Use cases / Conference talks
Slides for conference talks
Code that walks through itself line by line, notes that keep pace with your clicks, a countdown that tells you if you're running long, and questions from the room ranked by votes at the end.
Why it fits
What Kadal Deck gives you here
A presenter view built for timing
A countdown with a pacing badge for each slide, notes split at your clicks, and the next step, on your laptop while the projector shows only slides.
No Wi-Fi needed
kadal-deck dev and a static build run offline. If the venue's network works, the published link adds the room.
Questions from the room
People scan a QR code, ask and upvote from their phones, and the presenter view lists the questions with the most votes first.
The deck
A real one, ready to copy
The talk's opening, a code slide with four steps, and a closing slide with a QR code and the room's questions. It passes kadal-deck check as it stands.

## The deploy, one step at a time
```ts {1|3-6|8|all}
const build = await run("bun run build");
if (!build.ok) {
await notify("on-call", build.log);
process.exit(1);
}
await deploy({ canary: 0.05 });
```
<Notes>Build first. [click] A failed build pages whoever is on call. [click] Then five per cent of traffic. [click] That's the whole script.</Notes>

From an empty folder to the room
-
Start from the snippet
Paste it into deck.mdx of a new deck, or into a new deck in the browser builder.
-
Rehearse
Press S for the presenter view and run the countdown. R reads your notes aloud and turns the pages, if you want to hear the pacing.
-
Publish the night before
One command gives you a link with a live room; the deck still works from your laptop if the venue's network doesn't.

Share the slides afterwards
The same link stays up. Export a PDF for the organisers if they ask for a file.
