What Are We Wearing?

Hosts set a dress code, inspo photos and color rules for an event; guests open it with an invite code (no account needed), post what they plan to wear, vote on each other's "can't decide" polls and steer clear of clashes. Built with Next.js (App Router) and Supabase, hosted on Vercel. A guest mobile app lives in mobile/.

Sharing an event:

• Invite links get a preview image with the event's name, date, dress code, colors and first inspo photo (app/event/[code]/opengraph-image.tsx).
• Hosts can print a 5×7 invite card with a QR code from the event page (/event/<CODE>/card).

For hosts:

• Pinned updates. A note at the top of the event ("Ceremony moved outdoors, bring flats") that guests see live.
• Events with parts. A wedding weekend can have welcome drinks, the ceremony and brunch under it, each with its own code, dress code and outfits. Guests with the weekend's code see all of them; a part's code only opens that part. Add one from the parent event's page (/create-event?part_of=<CODE>).
• After the event, its page becomes "What everyone wore": guests can still add photos, but new polls are closed.
• Co-hosts. On the edit page, the host makes a private co-host link (/cohost/<token>) and sends it. Whoever opens it logs in or signs up and joins. Co-hosts can edit the event, pin updates and remove posts; only the owner can delete the event, add parts or manage the link. Making a new link or turning it off stops the old one working.

Linking guests to an event

Other platforms (invite and RSVP tools) can send guests straight to an event:

https://what-are-we-wearing-nu.vercel.app/event/<INVITE_CODE>?name=<Guest Name>#post

• name (optional) prefills the guest's name in the post form (URL-encode it, max 100 characters). It's only a suggestion that the guest can change. If they've already used a name for this event on that device, that name is kept instead. The parameter is removed from the address bar once read.
• #post (optional) scrolls straight to "Post Your Outfit".

Guests don't need an account. Names are remembered per event, with the last name used offered as the default for new events.

Linking hosts to create an event

Platforms can also send a host to a create page that's already filled in:

https://what-are-we-wearing-nu.vercel.app/create-event?name=Maya's%2030th&date=2026-11-14&location=Brooklyn&type=party&dress=Cocktail&host=Maya

All parameters are optional and URL-encoded. The host reviews everything before saving.

Param	Fills in	Notes
name	Event name	max 200 chars
date	Date	YYYY-MM-DD or a full ISO timestamp; invalid dates are left blank
location	Location	max 200 chars
type	Event type	wedding, dinner, party, other; common types like birthday or brunch are mapped, anything else becomes other
dress	Dress code	max 200 chars
host	Host's display name	max 100 chars

Hosts who aren't logged in are sent to log in or sign up first, then brought back to the filled-in page.

Running the tests

There's no local Supabase, so tests run against the real project as a dedicated test host account (a normal account used only for tests). Each run creates its own events named "WAWW automated test" and deletes them afterwards. Leftovers from a crashed run are swept up on the next run.

Add the test account to .env.local, next to the Supabase keys:

TEST_HOST_EMAIL=...
TEST_HOST_PASSWORD=...

The co-host tests also need a second account to join as a co-host: TEST_COHOST_EMAIL and TEST_COHOST_PASSWORD. Without them those tests are skipped.

• npm test runs the database tests (tests/db): guest posts, edits and deletes, likes, polls (hidden results, voting, deadlines, auto-close), host notes, events with parts, co-hosts and permissions.
• npm run test:e2e runs the browser tests (e2e) with Playwright. It reuses the dev server on port 3000 if one is running. First time only: npx playwright install chromium.

GitHub Actions (.github/workflows/ci.yml) runs lint, both test suites and a production build on every pull request and push to main. It needs these repository secrets: NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, TEST_HOST_EMAIL, TEST_HOST_PASSWORD.

Mobile app

mobile/ is an Expo app for guests, on the same Supabase backend. See mobile/README.md.

Development

npm install
npm run dev

Then open http://localhost:3000. .env.local needs NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY (plus the test account above to run the tests). Database changes go in supabase/migrations and are applied with npx supabase db push.
