Development Setup

Local Development

Gitpod-based workflow (dogfooding)
Component-based independent development
Leeway build system for dependency management
Containerized development mirroring production

Build Process

Approach	Description	Common Commands
In-tree (Local Dev)	• Direct in workspace • Language-specific tools	TypeScript: `yarn build` - Compile `yarn test` - Run tests `yarn lint` - Check style `yarn watch` - Auto-rebuild Go: `go build ./...` - Build packages `go test ./...` - Run tests `go run main.go` - Build and run
Leeway (CI/CD)	• Out-of-tree builds • Manages dependencies • Generates artifacts	`leeway build components/name:app` `leeway build -D components/name:app` `leeway exec --package components/name:app -- cmd`
Packaging	• Docker images via `leeway.Dockerfile` • Helm charts for K8s deployment

Testing Strategy

Unit tests: Component-level function/class testing
Integration tests: Cross-component interaction testing
End-to-end tests: Complete workflow validation
Preview environments: Dedicated feature testing

Technical Constraints

Category	Requirements
Performance	• Workspace startup < 10s when prebuilt • Low-latency IDE over internet • Efficient resource utilization
Security	• Strong workspace isolation • Least privilege component operation • Secure user code/credential handling • Controlled network access
Scalability	• Horizontal scaling for all components • Multi-cluster workspace distribution • Enforced workspace resource limits
Compliance	• GDPR: User data handling • SOC2: Security and availability • Data residency: Region-specific storage
