# VOLT — padel & squash template

> VOLT, a free open-source multi-club padel and squash booking website template built on the Storefront API — Next.js 15, a live hall map and court grid per club, crew-and-kit checkout, match-ticket confirmations, coach-led training, passwordless accounts.

## VOLT goes multi-club: a live hall map, a crew-and-kit checkout and match tickets

VOLT now models a **network of clubs**: four locations (Madrid, Barcelona,
Valencia, Málaga), each with its own padel doubles, padel singles and squash
courts. The **VOLT Padel & Squash** dataset seeds the whole network.

* **Club-first booking, full screen.** `/book` starts from one club: the linked one, the one the browser remembers, or "Near me" from the club coordinates. New visitors pick from photo cards with each club's soonest free court.
* **Hall map.** Every court from above, doubles wide and singles narrow, lit for one start time (free, free within the hour, free later, taken). Drag a time bar over the free-courts pulse; "Book 19:30" takes the best free court.
* **Grid view.** Courts × half hours, now per club, with the same duration popover.
* **One request per club.** A server route reads each court's merged availability once (no per-day or per-cell calls), caches it for 60 seconds and invalidates it on booking, cancel or reschedule; the browser computes the map, grid and "free from" locally.
* **Game flow checkout.** Numbered steps with a sticky match card: court (any or exact) → crew (names, email invites as appointment guests, price per player) → kit (add-ons) → details → payment. Trainings use the same flow with level, club, coach, day and places.
* **Match-ticket confirmation.** The court from above with a spot per player, a countdown, calendar file, directions, "Same time next week?".
* **My games.** Stats, the next game as a ticket, past games with "Book again", crew invites, change time and cancel.
* `/preview/[screen]` renders every confirmation and account state from fixtures.

## VOLT — open-source padel & squash club booking template

The fourth open-source Opencals template is live, and the first one built
around **staffless resources** instead of staff-led appointments. **VOLT** is a
padel & squash club booking website: the same
[Storefront API](https://opencals.com/docs/api-reference/introduction.md) and typed
[TypeScript SDK](https://opencals.com/docs/guides/storefront-sdk.md) as
[Haar](https://opencals.com/docs/changelog/haar-template.md), [Frisor](https://opencals.com/docs/changelog/frisor-template.md) and
[Clear Care](https://opencals.com/docs/changelog/clarity-template.md), with a dark technical design and a
different booking shape.

Two booking surfaces over one store: an in-page court grid for rentals, and a
classic coach-led flow for lessons and group classes. Every screen is built
with the public API.

* **Multi-court booking grid** — every court and every open slot for a day in one view, with a padel/squash toggle
* **Custom durations** — 30-minute steps to two hours, composed from consecutive free slots and priced live
* **Staffless resources** — courts use the `Self` rule with `maxAttendees: 1`, so each court is an independent, exclusively-booked unit
* **Coach-led training** — filter by sport, level and format; "Any coach — next available" leads the picker; group classes show live "N left" capacity
* Add-ons and custom checkout questions, Stripe payments with deposit support
* Passwordless customer accounts — 6-digit email login with password fallback, auto-login after checkout, one-time email links via `/link/[token]`
* `SportsActivityLocation` structured data, Open Graph, `robots.txt` and `sitemap.xml` configured
* Stack: Next.js 15, TypeScript, Tailwind v4, Framer Motion, `@opencals/storefront-sdk` v0.3.14
* MIT licensed — clone, rebrand, deploy. One-click Vercel deploy.

If you are booking courts, bays, lanes, studios or rooms rather than people,
VOLT is the closest starting point of the four.
