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
