1. Repository shape

- The repo is split into two top-level application areas:

- chaptered-web: the actual working client application

- chaptered-api: a backend package that currently looks like a scaffold/placeholder

- The root README.md describes the product vision and planned stack, but the implemented code is still early-stage.

2. Current runtime model

- The frontend is a React + TypeScript + Vite app running in the browser.

- The backend is a Node.js/TypeScript package, but from the tree alone it appears to have only a minimal entry file and no visible feature modules yet.

- So the current architecture is mostly client-side, with persistence likely happening locally rather than through an API.

3. Frontend composition

- chaptered-web/src/main.tsx is the browser entry point.

- App.tsx is the top-level application shell.

- The app is organized into pages:

- pages/Landing.tsx for the public marketing/entry experience

- pages/Library.tsx for the core reading/library workspace

- The presence of separate CSS files (landing.css, library.css, plus global styles) suggests page-scoped UI concerns rather than a large shared component system yet.

4. State and data ownership

- src/store/useLibraryStore.ts indicates the frontend uses Zustand for client state.

- This store is the likely source of truth for reading-library data in the current implementation.

- Because there is also a src/lib/storage.ts, the store likely persists or hydrates data from browser storage instead of calling a remote backend.

5. Domain logic boundary

- src/lib/bookUtils.ts suggests shared book-related transformation or formatting logic lives outside the UI layer.

- That file is the likely boundary for normalizing book data, computing derived values, or adapting external book records into the app’s internal shape.

- storage.ts is the other important non-UI boundary: it likely encapsulates browser persistence concerns so pages and stores don’t talk directly to storage APIs.

6. UI/data flow in the frontend

- User interaction starts in the page components.

- Page components read/write state through the Zustand store.

- The store likely uses bookUtils for derived book logic and storage.ts for persistence.

- The rendered output is therefore driven by a simple flow: user action → store update → persisted local state → UI re-render.

7. Backend status and boundary

- chaptered-api/src/index.ts exists, but the tree does not show routes, controllers, services, database models, or realtime modules.

- This means the backend boundary is present as a separate package, but its architecture has not been built out yet.

- For an architecture diagram, it should be shown as a planned service layer rather than a live dependency of the frontend right now.

8. Planned external integrations from the README

- The README names the future backend ecosystem:

- Google Books API for search

- MongoDB/Mongoose for persistence

- JWT for authentication

- Socket.io for realtime club chat

- None of those integrations are visible in the current file tree, so they should be treated as roadmap components, not current runtime dependencies.

9. Product boundaries implied by the codebase

- The current codebase only exposes the early reading/library side of the product.

- The larger Chaptered vision in the README includes clubs, chat, voting, analytics, and authentication, but those are not yet represented in the repository structure.

- In other words, the repo currently reflects a single-user library tracker shell, not the full social platform.

10. Infrastructure and tooling

- Frontend build tooling is Vite, with TypeScript config split for app and node environments.

- Both packages use npm lockfiles, so npm is the package manager in practice.

- ESLint is configured in the web app, indicating code-quality enforcement is already part of the frontend workflow.

11. How to draw the architecture accurately

- Show the browser app as the primary implemented system.

- Inside it, place:

- top-level app shell

- landing page

- library page

- Zustand library store

- helper modules for storage and book logic

- Show the backend as a separate but mostly empty service boundary.

- Show external services from the README as future integrations connected to the backend, not to the current frontend directly.

12. Bottom line

- This repository is at an early stage: the frontend prototype exists, the backend is just a scaffold, and the core architecture is local-state-driven UI with browser persistence.

- The key design boundary today is between presentation/pages and shared state + persistence helpers in the web app.
