Overview
Real-time dashboards display live data updates using WebSocket or SSE. This guide covers architecture, data streaming, and React implementation patterns for building dashboards that update in real-time without page refreshes.
Why This Matters
- User Experience: Real-time updates provide immediate feedback
- Decision Making: Live data enables faster decision making
- Engagement: Dynamic dashboards increase user engagement
- Performance: Efficient data streaming reduces server load
Core Concepts & Rules
1. Core Principles
- Follow established patterns and conventions
- Maintain consistency across codebase
- Document decisions and trade-offs
2. Implementation Guidelines
- Start with the simplest viable solution
- Iterate based on feedback and requirements
- Test thoroughly before deployment
Inputs / Outputs / Contracts
- Inputs:
- Dashboard ID or configuration
- Data source connections (database, APIs)
- Update interval or trigger conditions
- Chart configurations and thresholds
- Entry Conditions:
- WebSocket server running
- Data sources configured
- Chart library selected
- State management set up
- Outputs:
- Real-time data updates
- Live chart visualizations
- Connection status indicators
- Alert notifications
- Artifacts Required (Deliverables):
- Dashboard socket service
- Metrics streaming service
- Live chart components
- State management store
- Acceptance Evidence:
- Dashboard updates in real-time
- Charts render correctly
- Connection status accurate
- Alerts trigger appropriately
- Success Criteria:
- Update latency < 200ms
- Chart render time < 100ms
- Support 100+ concurrent connections
- Reconnection within 5 seconds

Quick Start / Implementation Example
- Review requirements and constraints
- Set up development environment
- Implement core functionality following patterns
- Write tests for critical paths
- Run tests and fix issues

# Example implementation following best practices
def example_function():
# Your implementation here
pass

Technical Guardrails & Security Threat Model
1. Security & Privacy (Threat Model)
- Top Threats: Injection attacks, authentication bypass, data exposure
2. Performance & Resources
3. Architecture & Scalability
4. Observability & Reliability
Agent Directives & Error Recovery
(ข้อกำหนดสำหรับ AI Agent ในการคิดและแก้ปัญหาเมื่อเกิดข้อผิดพลาด)
- Thinking Process: Analyze root cause before fixing. Do not brute-force.
- Fallback Strategy: Stop after 3 failed test attempts. Output root cause and ask for human intervention/clarification.
- Self-Review: Check against Guardrails & Anti-patterns before finalizing.
- Output Constraints: Output ONLY the modified code block. Do not explain unless asked.
Definition of Done (DoD) Checklist
Anti-patterns / Pitfalls
- ⛔ Don't: Log PII, catch-all exception, N+1 queries
- ⚠️ Watch out for: Common symptoms and quick fixes
- 💡 Instead: Use proper error handling, pagination, and logging
Reference Links & Examples
- Internal documentation and examples
- Official documentation and best practices
- Community resources and discussions
