# meal-order-manager

Automates weekly meal ordering from [Redefine Meals](https://www.redefinemeals.com) for Sea Haven Industries employees. Scrapes the menu, generates an order form, collects individual orders, and produces payroll deduction reports.

## Weekly Flow

| When | What | How |
|------|------|-----|
| Monday 6:55am ET | Sync employee roster from Slack channel membership | EventBridge → Lambda → DynamoDB |
| Monday 7am ET | Email previous week's payroll deductions to `payroll@` | EventBridge → Lambda → SES |
| Monday 8am ET | Scrape menu, generate form, upload to S3, post link to Slack | GitHub Actions cron |
| Mon–Thu | Employees visit `orders.seahaven.com` and submit orders | S3 static form → API Gateway → Lambda → DynamoDB |
| Thursday 10am ET | DM employees who haven't ordered yet | EventBridge → Lambda → Slack DM |
| Thursday 6pm ET | Close form, aggregate orders, post Redefine order summary to Slack | EventBridge → Lambda chain |

## AWS Resources

Stack name: `meal-order-manager` (us-east-1)

- **S3** — `meal-order-manager-form-*` (static form hosting), `meal-order-manager-reports-*` (CSV reports)
- **CloudFront** — HTTPS distribution with custom domain `orders.seahaven.com`
- **DynamoDB** — `meal-order-manager-orders` (orders, menu, roster, config)
- **API Gateway** — HttpApi for order submission
- **Lambda** — 6 functions: submit-order, close-form, aggregate-orders, slack-notifier, sync-roster, email-report
- **EventBridge** — scheduled rules (dual EST/EDT) for close, reminders, payroll email
- **Secrets Manager** — Slack bot token, form API key
- **SES** — payroll deduction emails

## Setup

### Local development

```bash
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
playwright install chromium
```

### Deploy to AWS

```bash
cp samconfig.toml.example samconfig.toml
# Edit samconfig.toml with your certificate ARN, etc.
sam build
sam deploy
```

### Post-deploy

1. Create the Slack bot token secret: `aws secretsmanager create-secret --name meal-order-manager/slack-bot-token --secret-string "xoxb-..."`
2. Create the form API key secret: `aws secretsmanager create-secret --name meal-order-manager/form-api-key --secret-string "$(openssl rand -hex 32)"`
3. Update the Slack channel SSM parameter: `aws ssm put-parameter --name /meal-order-manager/slack-channel-id --value "C0XXXXXXX" --overwrite`
4. Verify SES sender identity for `adam@seahavenind.com`
5. Set up DNS: CNAME `orders.seahaven.com` → CloudFront distribution domain
6. Roster syncs automatically from Slack channel members (runs Monday 6:55am ET), or seed manually: `python3 scripts/seed_roster.py`

## Local Workflow (no AWS)

The scraper, form generator, Flask server, and aggregator still work locally:

```bash
python3 src/scraper/scrape_menu.py        # scrape menu
python3 src/server/generate_form.py       # generate form (local mode)
python3 src/server/app.py                 # serve on localhost:5050
python3 src/aggregator/aggregate.py       # generate CSV reports
```

## Configuration

`config.json` (local dev):
- `menu_url` — Redefine Meals menu URL
- `order_deadline` — displayed on the form
- `roster` — employee list (name, email, slack_user_id)
- `output_dir` / `orders_dir` — local output paths
