1. Overall shape

- This repository is a hybrid farming app: a mostly static frontend in frontend/ plus a Node.js backend in backend/.

- The frontend delivers the product experience directly in the browser, while the backend mainly supports account/auth-related server functions and persistence.

2. Frontend presentation layer

- frontend/ is organized as multiple standalone HTML pages rather than a single SPA.

- Key pages include index.html, weather.html, market-price.html, crop-planner.html, education.html, ploughing-services.html, store.html, my-areastore.html, loan-calculator.html, comparison.html, and auth pages like login.html, register.html, forgot-password.html, reset-password.html, profile.html.

- style.css acts as the shared design system across the pages.

3. Frontend client-side logic

- frontend/api.js is the shared browser-side API client for talking to backend endpoints.

- frontend/auth.js handles user auth flows in the browser.

- frontend/nav.js centralizes navigation behavior, and frontend/i18n.js suggests language/localization support.

- This implies a page-driven UI where shared JS modules coordinate cross-page behavior.

4. Browser-only feature set

- Several parts of the app are meant to work without the backend, using browser APIs and local state.

- The README describes weather data, mandi prices, store/forum data, and other utilities that can run with external APIs or localStorage.

- This creates a split architecture: some features are server-backed, while others are client-only or can degrade gracefully offline.

5. Backend service boundary

- backend/server.js is the application entry point and likely mounts the Express app, middleware, and routes.

- backend/routes/authRoutes.js and backend/controllers/authController.js define the authentication boundary.

- Based on the file tree, the backend snapshot is focused on auth and user-account functionality rather than the full marketplace/forum feature set described in the README.

6. Data model layer

- backend/models/User.js is the primary account model.

- backend/models/Notification.js suggests server-side notification records.

- backend/models/PloughingService.js indicates a domain model for service listings.

- These models form the persistence boundary for backend-managed entities.

7. Persistence

- The repository includes db/kisan_sathi.db plus SQLite WAL files (.db-shm, .db-wal), which indicates the current snapshot uses a local SQLite database.

- This is an important architectural detail because it differs from the README’s MongoDB/Mongoose description.

- For diagrams, the durable store should be shown as a local database file under db/, not as a remote database service.

8. Email and notification flow

- backend/utils/sendEmail.js handles outgoing email, likely for password reset or account-related notifications.

- The auth controller and notification model together imply a flow where user actions on the frontend can trigger backend-side email and notification side effects.

9. Uploads and file handling

- backend/uploads/avatars/ is the visible upload area in the repo, suggesting profile-image storage on disk.

- The README also mentions other upload folders, but only avatars are present in the tree.

- This means the backend has a filesystem-based asset boundary in addition to database persistence.

10. Domain features surfaced in the UI

- The frontend pages map to user-facing product areas: weather intelligence, market prices, crop planning, education, community, store browsing, local agricultural services, comparison tools, and loan calculation.

- Some of these are likely self-contained visual/educational tools; others rely on backend data or browser storage.

- For an architecture diagram, these should be shown as separate frontend feature areas with only some connected to the backend.

11. External integrations

- The README explicitly references OpenWeatherMap and data.gov.in for weather and mandi prices.

- These are external API dependencies from the frontend, not from the backend tree shown here.

- They matter because they bypass the application server for key live-data features.

12. Repository caveat

- The README describes a broader full-stack system with forum, store, and order APIs, but the checked-in backend tree does not include those route/controller files.

- So the safest architecture read is: a frontend-heavy app, a focused auth backend, SQLite persistence, disk-based uploads, and direct browser calls to third-party data providers.
