Journi is a web application for journaling and visualizing travel experiences. Users log trips by country, pinning cities, dates, transport modes, and photos. Then user can explore their journey on an interactive world map, timeline view or can play short animations overviewing his trips.

How It Works

Sign in with a Google account.
Select your home country — it is automatically marked as visited on the map.
Add journal entries:
- Step 0 — Click on country in map you visited or click add trip in timeline.
- Step 1 — Choose country, cities, arrival date, days stayed, trip type (solo/friends/family), and transport (flight/train/bus/car/ship/walk).
- Step 2 — Upload photos (stored in Firebase Storage).
- Step 3 — Answer three random reflective questions about the trip (e.g., "What was the most unexpected thing that happened?").
Edit entries through the same form, pre-filled with existing data.
View your journey on a D3-powered world map where visited countries are highlighted and animated flight paths connect entries in chronological order.
Browse a timeline sorted by date, country, or recency.
Share a generated summary card to show off your stats.

Backend — Firebase

Journi uses Firebase as its backend. Users sign in with Google through Firebase Authentication, and their data is linked to their user ID.

Firestore stores user profiles in users/{uid} and journal entries in users/{uid}/entries/{id}. Firebase Storage stores uploaded trip photos.

Firebase Security Rules protect the data, so authenticated users can only read and write their own profiles, entries, and photos.
