ANU Tennis Club court booking

One page where an ANU Tennis Club (ANUTC) member books a court and sees, before they book, what their membership and Booking Package make free and what the rest will cost. Today that path crosses systems that don’t know about each other: membership and the package live in the ANU Sport UniOne account, which has no bookings; court booking lives in a separate portal, which shows no membership or package; and the club’s own site holds neither. This app puts the member, the rules and the timetable in one place.

It is a model, not a replacement. The members are invented demo people, and nothing here talks to ANU Sport.

What it does

• Pick a member, a court and a day, then tick the hours. Courts open 06:00–22:00 in one-hour slots; a booking is one unbroken run of slots on one court. Hours someone else holds are greyed out before you pick them, and update live on every open page when anyone books.
• The member’s status is on the page: ANUTC membership, Booking Package, whether that day’s free hours are still there, and when lights start.
• Confirmation is immediate, with the free hours, hire and lights itemised. After booking through the portal, the author waited about a day for a confirmation email.
• Played bookings stay listed, marked completed. The portal’s My Bookings says “Bookings will disappear from this list after they have completed.”
• The server re-checks every booking against the database when it’s submitted, because two people can be looking at the same free hour. A refusal says which rule stopped it.

The rules, and where each comes from

• Free hours: a current Booking Package gives the first two hours of one booking a day free, dark or not. A second booking that day pays full hire. The club’s words: “up to two consecutive hours of complimentary ANU Tennis Court hire per day, on the same court”.
• Hire: beyond the free hours, or without a current package, $15 an hour for students and $20 for the general public, from ANU Sport’s facility price list.
• Lights: $8 an hour for every hour after dark, on top of hire, whether that hour’s hire is free or paid. Daylight ends at 17:00, or 19:00 during daylight saving (from 4 October 2026).
• Notice: at least 30 minutes, and at most 14 days ahead, as the booking portal enforces.
• Package: expires 1 March the following year, so it covers bookings up to 28 February. It “is only available to those with a current ANUTC Membership”, which the club says is valid “until the end of February the following year”. Without a current membership the package gives no free hours, but the court can still be booked at the price-list rate.

Where this departs from what the club publishes

• The $8. The club’s page says court use beyond the two free hours “or occurring outside of daylight hours will be charged at the applicable rate of $8.00 per hour”, a single flat rate. This app instead charges hire at the price-list rate and adds $8 an hour for lights, because that is how the author has actually been billed. The two readings give different totals, and the app follows the bill.
• Which expiry. UniOne shows membership expiring on 31 December; the club says the end of February. The app uses the club’s date.
• Notice. The club advises booking at least 24 hours ahead; the portal allows 30 minutes. The app uses the portal’s 30 minutes, since it confirms at submission.

What it doesn’t do

• No login. You pick a demo member from a list: a student with a package, one with none, one whose package expired, two general-public members, and a non-member. Anyone can book as any of them.
• No payment. It says what is owed; nothing is charged.
• No cancellations.

What’s checked

pnpm check builds the app and runs spec/ against the built server: booking-rules.test.ts holds the rules above as a contract on the one function the server prices with, and booking-flow.test.ts drives the running app over HTTP: a booking survives a reload, refusals store nothing, lights change at the daylight-saving boundary, and a played booking stays listed as completed. Whether the page is clear to a member who has never seen it is a judgement no test makes.
