🧠 Prompt: “Develop the Nexus UI (Pilot)”

Browse files

Context:
We have built the backend for our internal analytics tool “Nexus” using FastAPI, SQLAlchemy, and Alembic (Python).
The backend currently runs locally on http://127.0.0.1:8000 and exposes a working REST API with OpenAPI docs.

Here is what is already working:
• CSV ingestion endpoint: /api/ingest
→ validates, normalizes, and optionally persists workforce CSV files
• Audit log endpoint: /api/audit
→ lists all ingestion events (success/failure, timestamp, file, etc.)
• Runs endpoint: /api/runs
→ shows all persisted ingestion runs
• Database: SQLite at /data/nexus.db
→ Tables: ingestion_runs, audit_log, alembic_version
• Backend path: C:\Users\Chris\nexus-core\backend
• API modules:
• api/ingest.py → main ingestion logic
• api/audit.py → audit log
• api/runs.py → ingestion run listing
• Frontend goal: a simple, modern dashboard-style UI to interact with the existing API.



🎯 Objective

Develop a minimal but professional frontend (pilot) for Nexus, focusing on data ingestion and audit visibility.
It should serve as a proof-of-concept dashboard to validate the backend and user experience.



🧩 Tech Stack (recommended)

You can choose, but preferred options are:
• React + Vite (TypeScript)
• TailwindCSS or Material UI for design
• Axios for API calls
• Optional: React Query for data fetching & caching



🖥️ Required UI Pages / Components
1. Home / Dashboard
• Header with “EbX Nexus” logo and simple navigation bar
• 2 main sections:
• Upload & Validate CSV
• Upload button (POST /api/ingest?persist=true)
• Display file validation summary and preview table
• Recent Uploads / Audit Log
• Table fetching from /api/audit
• Columns: Date, Event Type, Entity, Description
• Optional filter/search by file or date
2. Runs Page
• Fetch /api/runs
• Display persisted ingestion runs with columns: ID, Filename, Rows, Status, Date
• Link each run to a detail modal (future enhancement)
3. System Health
• Simple check of /health endpoint with green/red indicator



⚙️ Features to Implement
• File upload → POST to /api/ingest
• Table rendering → Audit logs and ingestion runs
• Status messages (success/error)
• Minimal responsive layout
• Local config (API base URL = http://127.0.0.1:8000)
• Optional: Dark/light mode toggle



🧭 Next Steps after UI Pilot

Once the pilot UI is complete and functional:
1. Add JWT login for admin/viewer roles
2. Add insights dashboard page calling /api/insights (once available)
3. Bundle everything into Docker Compose for full-stack deployment



🪄 Prompt Goal

Please:
• Generate the project scaffolding (e.g., npx create-vite nexus-ui --template react-ts)
• Create the main components (Upload, AuditTable, RunsTable, HealthIndicator)
• Show example code for API integration and page routing
• Style it cleanly using Tailwind or MUI
• Include mock data fallback for testing without the backend



✅ Deliverables
• Folder structure proposal
• Example React component code
• API integration examples
• Styling setup (Tailwind config or MUI theme)
• Instructions to run locally (npm run dev
