# CLAUDE.md — KMountain Flower Radio Station

## Project overview

A three-tier web app for a community radio station: Angular 21 frontend, FastAPI backend, PostgreSQL database. Renders a hero page, about page, broadcast schedule, donation tiers, upcoming events, and a contact form — styled with a warm mountain/nature color palette (blue primary + orange accent on cream).

## Code style

- **Components:** Standalone only (no NgModules). Every component is a single file with `@Component` decorator, `imports` array, and four standard files (`.ts`, `.html`, `.scss`, component).
- **Data patterns:** Page content (programs, events, tiers) is stored in PostgreSQL and served via the FastAPI backend. The frontend uses HTTP services ([src/app/services/](src/app/services/)) to fetch data at runtime. To add or modify content, interact with the API or run `seed.py` — never hardcode content in components.
- **SCSS:** All design tokens go in [src/styles/_variables.scss](src/styles/_variables.scss). Mixins in [_mixins.scss](src/styles/_mixins.scss). CSS custom properties exposed in [_themes.scss](src/styles/_themes.scss). Components import via `@use 'variables'` (no relative path needed).
- **Routes:** Defined in [src/app/app.routes.ts](src/app/app.routes.ts) using `loadComponent()` lazy loading. Add new pages here after creating the component.
- **TypeScript:** Strict mode enabled. Use `readonly` for constants (config, URLs). Keep data shapes close to their components where used only once.

## Architecture

See [README.md](README.md) for a full architecture map. Key files:

- `src/app/app.routes.ts` — all frontend routing
- `src/environments/environment.ts` — dev API URL (`http://localhost:8000`)
- `src/environments/environment.prod.ts` — prod API URL (`''`, proxied through Nginx)
- `src/styles/_variables.scss` — color palette, spacing, breakpoints (change these to re-skin)
- `src/styles/_mixins.scss` — card-style, button-style, responsive, gradient-text, flowery-border, fade-in
- `src/styles/_themes.scss` — SCSS → CSS custom property mapping
- `docker-compose.dev.yml` — dev-sidecar compose for VS Code dev container
- `backend/app/main.py` — FastAPI entry point (CORS, router registration)
- `backend/app/models.py` — SQLAlchemy ORM (Program, Event, DonationTier)

## Common tasks

- **Re-skin:** Edit colors in `_variables.scss` only.
- **Add a page:** Create component folder → add route in `app.routes.ts` → add nav link (if needed).
- **Update content (dev):** Run the API, then use Swagger UI at [http://localhost:8000/docs](http://localhost:8000/docs) to create/update content.
- **Update content (seed):** Edit [backend/seed.py](backend/seed.py) and restart the API (autoseed runs on empty DB), or hit `curl -X POST http://localhost:8000/api/admin/reset` to re-seed.
- **Run the app (dev):** From the `backend/` directory, set `KMTN_DATABASE_URL=sqlite+aiosqlite:///./kmountain.db`, then `uvicorn app.main:app --reload` + `ng serve` in parallel. Autoseed populates data on first run.
- **Run the app (dev container):** Reopen in Container via VS Code.
- **Build:** `ng build` → `dist/`.
