# HOA LedgerIQ - Scripts

Standalone scripts for data fetching, maintenance, and automation tasks.

## CD Rate Fetcher

Scrapes the top 25 CD rates from [Bankrate.com](https://www.bankrate.com/banking/cds/cd-rates/) and stores them in the `shared.cd_rates` PostgreSQL table.

**Note:** Bankrate renders rate data dynamically via JavaScript, so this script uses Puppeteer (headless Chrome) to fully render the page before extracting data.

### Prerequisites

- Node.js 20+
- PostgreSQL with the `shared.cd_rates` table (created by `db/init/00-init.sql` or `db/migrations/005-cd-rates.sql`)
- A `.env` file at the project root with `DATABASE_URL`

### Manual Execution

```bash
cd scripts
npm install
npx tsx fetch-cd-rates.ts
```

### Cron Setup

To run daily at 6:00 AM:

```bash
# Edit crontab
crontab -e

# Add this line (adjust path to your project directory):
0 6 * * * cd /path/to/HOA_Financial_Platform/scripts && /usr/local/bin/npx tsx fetch-cd-rates.ts >> /var/log/hoa-cd-rates.log 2>&1
```

For Docker-based deployments, you can use a host cron job that executes into the container:

```bash
0 6 * * * docker exec hoa-backend sh -c "cd /app/scripts && npx tsx fetch-cd-rates.ts" >> /var/log/hoa-cd-rates.log 2>&1
```

### Troubleshooting

- **0 rates extracted**: Bankrate likely changed their page structure. Inspect the page DOM in a browser and update the CSS selectors in `fetch-cd-rates.ts`.
- **Database connection error**: Verify `DATABASE_URL` in `.env` points to the correct PostgreSQL instance. For local development (outside Docker), use `localhost:5432` instead of `postgres:5432`.
- **Puppeteer launch error**: Ensure Chromium dependencies are installed. On Ubuntu: `apt-get install -y libnss3 libatk1.0-0 libatk-bridge2.0-0 libcups2 libdrm2 libxkbcommon0 libxcomposite1 libxdamage1 libxrandr2 libgbm1 libpango-1.0-0 libasound2`
