Development Workflow

Development processes, code quality standards, testing protocols, and deployment procedures

Development Philosophy

Core Principles

Plan → Code: Implementation roadmaps before development
API-First: Headless architecture with clean separation
Quality First: Code review and testing requirements
Documentation Driven: Comprehensive technical documentation
Incremental Delivery: Small, iterative improvements

Technical Standards

TypeScript Strict: No `any` types, comprehensive typing
Modern Stack: Latest stable versions of all dependencies
Performance Focus: Sub-400ms response time targets
Security by Design: Security considerations in every feature
Open Architecture: No vendor lock-in, interoperable design

Development Process

1
Planning & Requirements

Implementation Roadmaps

• Objective Definition: Clear feature goals and success criteria
• Acceptance Criteria: Specific, testable requirements
• Risk Assessment: Technical and business risk identification
• Test Hooks: Testing strategy and verification methods
• Timeline Planning: Development phases and milestones

docs/progress/[feature]-roadmap.md

Architecture Decisions

• ADR Documentation: Architecture Decision Records
• Technical Proposals: Design review and approval
• Integration Planning: System interaction design
• Performance Considerations: Scalability and optimization
• Security Review: Threat modeling and mitigation

2
Development & Implementation

Code Standards

• TypeScript Strict: Comprehensive type safety
• ESLint Configuration: Automated code quality checks
• Prettier Formatting: Consistent code formatting
• Component Architecture: Reusable, focused components
• API Integration: Clean service layer separation

Development Tools

• Next.js 14: Modern React framework with App Router
• TailwindCSS: Utility-first CSS framework
• SWR: Data fetching and caching library
• Task Master: Development task management
• Memex AI: AI-assisted development and review

3
Testing & Quality Assurance

Testing Strategy

• Unit Testing: Component and function-level tests
• Integration Testing: API and service integration verification
• End-to-End Testing: Complete user workflow testing
• Performance Testing: Load and response time validation
• Security Testing: Vulnerability scanning and assessment

Quality Metrics

• Code Coverage: Minimum 80% test coverage
• Performance Budget: Core Web Vitals compliance
• TypeScript Coverage: 100% type safety
• Accessibility: WCAG 2.1 AA compliance
• Browser Compatibility: Modern browser support

4
Deployment & Monitoring

Deployment Process

• Pre-deployment Checks: GCP project verification
• Build Optimization: Asset optimization and compression
• Zero-downtime Deploy: Blue/green deployment strategy
• Health Monitoring: Post-deployment verification
• Rollback Capability: Immediate rollback on issues

Monitoring & Alerts

• Performance Monitoring: Real-time response time tracking
• Error Tracking: Automated error detection and reporting
• Uptime Monitoring: 24/7 availability tracking
• User Experience: Core Web Vitals monitoring
• Security Alerts: Threat detection and response

Git Workflow & Version Control

Branching Strategy

main

Production-ready code, deployed to live environment

develop

Integration branch for feature development

feature/*

Individual feature development branches

hotfix/*

Emergency fixes for production issues

Commit Standards

Conventional Commits

Code Quality Standards

TypeScript Configuration

Strict Mode Settings

• strict: true - Maximum type checking
• noImplicitAny: true - Explicit typing required
• noImplicitReturns: true - All code paths return
• noUnusedLocals: true - No unused variables
• exactOptionalPropertyTypes: true - Precise optional types

Type Safety Benefits

• Runtime Safety: Catch errors before deployment
• Developer Experience: Better IDE support and autocompletion
• Refactoring Confidence: Safe large-scale changes
• Documentation: Types serve as inline documentation
• Team Collaboration: Clear interfaces and contracts

Linting and Formatting

ESLint Configuration

• Next.js Rules: Framework-specific best practices
• TypeScript Rules: Type-specific linting
• React Hooks Rules: Hook usage validation
• Accessibility Rules: A11y compliance checking
• Security Rules: Common vulnerability detection

Prettier Formatting

• Consistent Style: Automatic code formatting
• Team Alignment: No style debates or inconsistencies
• Git Cleanliness: Fewer style-only changes
• Editor Integration: Format on save capability
• Pre-commit Hooks: Enforced formatting standards

Performance Standards

Core Web Vitals

• LCP (Largest Contentful Paint): <2.5 seconds
• FID (First Input Delay): <100 milliseconds
• CLS (Cumulative Layout Shift): <0.1
• FCP (First Contentful Paint): <1.8 seconds
• TTI (Time to Interactive): <3.8 seconds

Optimization Techniques

• Code Splitting: Dynamic imports for large components
• Image Optimization: Next.js Image component with WebP
• API Caching: SWR for intelligent data caching
• Bundle Optimization: Tree shaking and minification
• CDN Delivery: Global asset distribution
