# Bookra Backend
Go + Gin API for Bookra, designed for Railway deployment with Neon Auth, Neon Postgres, and Paddle billing.
## Commands
```bash
go run ./cmd/api
go build ./...
npm run db:generate
npm run db:migrate:status
npm run db:migrate:up
```
## Environment
- `BOOKRA_FRONTEND_URL` allowed browser origin
- `BOOKRA_DATABASE_URL` Neon pooled connection
- `BOOKRA_DATABASE_DIRECT_URL` Neon direct connection for migrations/admin tasks
- `BOOKRA_NEON_AUTH_URL` Neon Auth base URL used for JWKS verification
- `BOOKRA_AUTH_JWT_SECRET` optional local JWT fallback when not using Neon Auth
- `BOOKRA_JOB_RUNNER_KEY` shared secret for remote reminder dispatch calls
- `BOOKRA_EMAIL_FROM` sender identity for email reminders
- `BOOKRA_PADDLE_ENV` billing environment: `sandbox` or `live`
- `BOOKRA_PADDLE_API_KEY` Paddle API key
- `BOOKRA_PADDLE_WEBHOOK_SECRET` Paddle notification destination secret
- `BOOKRA_PADDLE_{STARTER,PRO,BUSINESS}_{CZK,USD}_PRICE_ID` Paddle price IDs
- `BOOKRA_UMAMI_API_URL` and `BOOKRA_UMAMI_API_KEY` optional analytics integration
## Notes
- Auth verification is isolated in `internal/auth`.
- OpenAPI lives in `openapi/bookra.openapi.yaml`.
- SQL migrations live in `migrations/`.
- `sqlc.yaml` is wired through `npm run db:generate`.
- Goose migrations are wired through `npm run db:migrate:*` and use the Neon direct connection URL.
- Reminder dispatch now runs through `POST /v1/internal/jobs/reminders/dispatch` with `X-Bookra-Job-Key`.
## Production Auth
Bookra production auth should use Neon Auth directly:
- frontend uses `VITE_NEON_AUTH_URL`
- backend verifies Neon JWTs with `BOOKRA_NEON_AUTH_URL`
- auth-service may stay deployed for standalone auth/admin workflows, but backend billing and app APIs do not depend on it
Trusted redirect domains in Neon Auth should include your frontend origin such as `https://bookra.eu`, plus local dev origins when needed.
## Paddle Setup
Get these values from Paddle dashboard:
- `BOOKRA_PADDLE_ENV`: `sandbox` for testing, `live` for production
- `BOOKRA_PADDLE_API_KEY`: Developer tools -> Authentication
- `BOOKRA_PADDLE_WEBHOOK_SECRET`: Notification settings -> destination secret key
- `BOOKRA_PADDLE_*_PRICE_ID`: Catalog -> each SaaS plan recurring price ID
Create one recurring price per plan/currency you support:
- `starter` `czk`
- `starter` `usd`
- `pro` `czk`
- `pro` `usd`
- `business` `czk`
- `business` `usd`
Set your webhook destination to:
```text
POST /v1/webhooks/paddle
POST /api/paddle_webhook
```
Use Paddle webhook simulator for event testing.
