Web UI Development for CrawlLama

[arn-c0de]

Description

Design and implement a modern web-based chat interface for CrawlLama, complementing the existing CLI. The UI should use the existing REST API and deliver an intuitive, accessible, and responsive chat experience.

Current State

• Done: FastAPI backend with /query, /memory, /health endpoints
• Done: Session management and memory store
• Done: CLI interface (Rich terminal UI)
• Missing: graphical frontend
• Missing: chat UI components

Tasks

Planning & Design

• Research chat UI best practices (Intercom, ChatGPT, Discord)
• Create wireframes for desktop and mobile
• Design high-fidelity mockups (Figma):
  • Chat conversation view
  • Message bubbles (user/agent)
  • Input composer with OSINT operators
  • Settings panel
  • Memory Store viewer
  • Health dashboard integration
• Define component architecture (React / Vue / Svelte)

Implementation

• Set up frontend framework (React + Tailwind/Chakra recommended)
• Develop reusable components:
  • <ChatMessage> - user/agent message bubble
  • <MessageComposer> - input field with OSINT suggestions
  • <ConversationList> - chat history
  • <MemoryPanel> - display stored OSINT data
  • <SettingsPanel> - live configuration editing
  • <StatusBar> - context and token usage tracker
• Integrate with existing API:
  • POST /query - send messages
  • GET /memory - display memory data
  • GET /context/status - track token/context usage
  • Optional: WebSocket support for streaming responses
• Implement responsive design (mobile / tablet / desktop)
• Add accessibility features (WCAG 2.1):
  • Keyboard navigation
  • Screen reader support
  • High contrast mode

Testing & Deployment

• Component tests (Jest / Vitest)
• Integration tests with API
• Performance optimization (lazy loading, virtualization)
• Create Docker container for web UI
• Write deployment documentation

Acceptance Criteria

• Interactive web UI accessible via browser (e.g., http://localhost:3000)
• Full integration with existing CrawlLama API endpoints
• Responsive design across all major devices
• WCAG 2.1 AA accessibility compliance
• Dockerfile and deployment guide provided
• User documentation with annotated screenshots

Technical Stack Suggestion

Category	Recommendation
Frontend Framework	React (Next.js optional for SSR) + TypeScript
UI Framework	Tailwind CSS + Headless UI / Radix UI
State Management	Zustand (lightweight) or Redux Toolkit (complex flows)
API Client	Axios (with interceptors) or native Fetch wrapper
Build Tool	Vite (fast dev builds) or Next.js (if SSR needed)
Testing	Vitest + React Testing Library
Real-Time	WebSocket or Server-Sent Events (for streaming responses)
Containerization	Docker (multi-stage build for lightweight image)
