# Spanglish — Language Exchange Event Platform

A full-stack web app for organizing and managing language exchange events (Asunción, Paraguay).

## Features

- **Public site**: events, booking, contact, community, legal pages, bilingual (EN/ES)
- **User dashboard**: profile, tickets, payments, sessions/security
- **Admin** (`/admin`): events, tickets/check-in, users/roles, payments, email templates, media uploads
- **API**: Swagger UI at `/api-docs`, OpenAPI JSON at `/openapi.json`, health check at `/health`

## Tech stack

- **Backend**: Node.js + TypeScript, Hono, Drizzle ORM, SQLite (default) or PostgreSQL
- **Auth**: JWT (via `jose`), **Argon2id** password hashing (with legacy bcrypt verification for older hashes)
- **Email**: `nodemailer` (SMTP) with optional provider config
- **Frontend**: Next.js 14 (App Router), Tailwind CSS, SWR, Heroicons

## Local development

### Prerequisites

- Node.js 18+
- npm

### Setup

```bash
npm install
cp backend/.env.example backend/.env
cp frontend/.env.example frontend/.env
```

### Initialize database (SQLite by default)

```bash
npm run db:migrate
```

### Run

```bash
npm run dev
```

Default URLs:

- Frontend: `http://localhost:3002`
- Backend API: `http://localhost:3001`
- API docs: `http://localhost:3001/api-docs`

### First user becomes admin

The first user to register becomes the **admin**. Register at `/register`.

## Useful scripts (workspace)

Run these from the repo root:

```bash
npm run dev
npm run build
npm run start
npm run db:generate
npm run db:migrate
npm run db:studio
```

You can also run per workspace:

```bash
npm run dev --workspace=backend
npm run dev --workspace=frontend
```

## Environment variables

### Backend (`backend/.env`)

Key settings (see `backend/.env.example` for the full list):

- **DB**: `DB_TYPE=sqlite|postgres`, `DATABASE_URL=./data/spanglish.db` (or Postgres URL)
- **Auth**: `JWT_SECRET` (change in production)
- **URLs/ports**: `PORT`, `API_URL`, `FRONTEND_URL`
- **Email**: `EMAIL_PROVIDER` (`console|smtp|resend`) and corresponding credentials
- **Payments (optional)**: Stripe/MercadoPago/LNbits configuration

### Frontend (`frontend/.env`)

Key settings (see `frontend/.env.example`):

- **Server port**: `PORT=3002`
- **API base URL**: `NEXT_PUBLIC_API_URL` (optional)
  - Leave empty to use same-origin `/api` (recommended when running behind nginx)
  - In local dev, Next.js rewrites `/api/*` and `/uploads/*` to the backend
- **Social links (optional)**: `NEXT_PUBLIC_WHATSAPP`, `NEXT_PUBLIC_INSTAGRAM`, etc.

## Database

### SQLite (default)

- DB file defaults to `backend/data/spanglish.db` (via `DATABASE_URL=./data/spanglish.db`)
- Run migrations with `npm run db:migrate`

### PostgreSQL

Set in `backend/.env`:

```env
DB_TYPE=postgres
DATABASE_URL=postgresql://user:password@localhost:5432/spanglish
```

Then run:

```bash
npm run db:migrate
```

## Production deployment (nginx + systemd)

This repo includes example configs in `deploy/`:

- **systemd**: `deploy/spanglish-backend.service`, `deploy/spanglish-frontend.service`
  - Backend runs on **3018**, frontend on **3019** by default (see the unit files)
  - Backend needs write access to `backend/data` and `backend/uploads`
- **nginx**:
  - `deploy/spanglish_upstreams.conf` defines upstreams for ports 3018/3019
  - `deploy/front-end_nginx.conf` proxies `/api` and `/uploads` to the backend and everything else to the frontend
  - `deploy/back-end_nginx.conf` is a dedicated API vhost example with CORS handling

Typical production flow:

```bash
npm ci
npm run build
npm run db:migrate
```

Then install/enable the systemd services and nginx configs for your server.
