## Development Workflow
### 1. Create a Feature Branch
```bash
git checkout -b feature/my-feature
```
### 2. Make Changes
- Write code following TypeScript strict mode
- Add tests for new functionality
- Update documentation if needed
### 3. Run Tests Locally
```bash
# All tests
pnpm test
# Specific service
pnpm --filter @goodgo/iam-service test
```
### 4. Lint and Format
```bash
pnpm lint
pnpm format
```
### 5. Create Pull Request
- Push your branch
- Create PR targeting `develop`
- CI/CD will run automatically
## Adding a New Service
1. Use the template:
```bash
./scripts/utils/create-service.sh my-new-service
```
2. Update service configuration
3. Implement business logic
4. Add tests
5. Update documentation
## Adding a New Package
1. Create package in `packages/new-package`
2. Add to workspace in `pnpm-workspace.yaml`
3. Export from `index.ts`
4. Add tests
5. Document usage
## Database Migrations
## Database Migrations
```bash
# Create migration (dev)
./scripts/db/migrate.sh iam-service dev
# Apply migrations (production)
./scripts/db/migrate.sh iam-service deploy
```
## Kubernetes Deployment
### Local Kubernetes (Docker Desktop)
```bash
# Enable Kubernetes in Docker Desktop
# Settings → Kubernetes → Enable Kubernetes
# Deploy service
cd deployments/local/kubernetes
./deploy.sh
# Verify deployment
kubectl get pods -n iam-local
kubectl logs -f -n iam-local -l app=iam-service
# Port forward for testing
kubectl port-forward svc/iam-service 5002:80 -n iam-local
curl http://localhost:5002/health/live
```
**See detailed guide**: [Kubernetes Local Deployment Guide](./kubernetes-local.md)
## Debugging
- Use logger from `@goodgo/logger`
- Check Traefik logs: `docker logs traefik-local`
- Check service logs: `./scripts/dev/logs.sh iam-service`
