Real-time meetups with shared maps, live ETAs, and a built-in group chat—no logins required.
MapWise is a cross-platform coordination tool for friend groups and teams who need to meet in the real world. One person creates a “room,” picks a destination, and shares a link. Everyone who joins is placed on a shared map with live routing, arrival transparency, and contextual chat so there is never another “I’m five minutes away” mystery.
- Live shared map built with MapLibre and Expo—watch every participant move toward the meetup spot in real time.
- Automatic routing + ETA tracking powered by the public OSRM API and Prisma-backed persistence.
- Integrated chat so the logistics conversation stays inside the map view.
- Zero-login join links: anyone with the URL can hop in from web or mobile with a name and location permission.
- Presence-aware rooms: socket-powered status indicators show who’s online and when someone disconnects.
The repo is organized as a Turborepo monorepo with dedicated apps for every audience and shared packages for types, state, and hooks.

- Web (
apps/web) – Marketing site + lightweight desktop join/create flow driven by Next.js 15, Tailwind, and interactive hero sections with demo video. - Mobile (
apps/mobile) – Expo Router app using MapLibre for rendering multi-user polylines, NativeWind for styling, and shared hooks/state for session management. - Server (
apps/server) – Express API plus Socket.io gateway. Prisma persists rooms, users, live location, and messages in PostgreSQL while route data is cached as JSON blobs. - Shared packages –
@repo/types(TypeScript contracts for sockets, Prisma DTOs),@repo/store(Redux Toolkit slices + providers),@repo/hooks(session/socket hooks reused on web + mobile), and tooling packages (eslint-config,typescript-config).
- Frontend: Next.js 15, React 19, Tailwind CSS, Expo Router, MapLibre GL, NativeWind.
- Backend: Node 20+, Express 5, Socket.io 4, Prisma 6, PostgreSQL, OSRM routing API.
- Tooling: Turborepo, pnpm workspaces, TypeScript everywhere, Zod, Redux Toolkit, PM2/Nginx-ready docker assets.
- Node 18+ and pnpm 9 (
corepack enablerecommended) - PostgreSQL instance (Docker works great)
- Expo Go or a dev client for running the mobile app
pnpm installCreate apps/server/.env:
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/mapwise
PORT=4000
Run Prisma migrations to set up the schema:
cd apps/server
pnpm prisma migrate deploypnpm dev --filter=serverThe server exposes REST at http://localhost:4000/api/* and Socket.io on the same origin.
pnpm dev --filter=webVisit http://localhost:3000 to create/share rooms from the browser.
pnpm dev --filter=mobileUse the Expo CLI output to open on iOS, Android, or web. The app consumes the same API + sockets; set EXPO_PUBLIC_API_URL if you point at a remote backend.
POST /api/room/create-room– Create a room, persist destination, create the host user, and prefetch OSRM route data.POST /api/room/join/:roomId– Join an existing room and backfill the route from the user’s position to the destination.GET /api/users/:roomId– Fetch everyone currently assigned to a room (used for reconnections).GET /api/messages/:roomId– Room history hydrator for chat transcripts.
Realtime events (Socket.io):
joinRoom/disconnect– Track room membership, online status, and last-known position.update-location→location-update– Broadcast latitude/longitude deltas to everyone else.send-message→new-message– Persist chat entries before fan-out to the room.currentUsers,current-messages,newUser,user-disconnected– Bootstrap payloads the moment a socket connects.
