I built the VELOZITY_assignment repository as a production‑grade, full‑stack real‑time client project dashboard for agency environments. It uses a TypeScript codebase and runs on Node v20+ with Express, PostgreSQL, Prisma, Socket.IO and node‑cron on the backend, while the frontend is powered by React 18, Vite, React Router v6, Tailwind CSS and Axios with an interceptor for HttpOnly JWT refreshes.
Repository language is TypeScript.
Repository created in 2026‑09 and last updated in 2026‑09.
Backend runtime is Node.js v20+ with TypeScript.
Backend framework is Express.js, chosen for lean, maintainable, predictable middleware pipelines and minimal bundle overhead.
Database is PostgreSQL with foreign keys, composite indexes and strict cascade/restrict rules.
ORM is Prisma ORM for type‑safe query construction and automated client generation.
Real‑time layer uses Socket.IO for authenticated WebSocket connections with presence tracking and role‑scoped rooms.
Background jobs are handled by node‑cron for in‑process cron scheduling of overdue task checks.
Security and validation libraries include jsonwebtoken, bcryptjs, cookie-parser and zod.
Frontend framework is React 18 with TypeScript.
Bundler is Vite for fast hot‑module replacement and optimized production chunks.
Routing uses React Router v6 for nested layout and authenticated route protection.
Styling is done with Tailwind CSS for a clean, responsive UI.
HTTP client is Axios, configured with credentials and an interceptor that automatically refreshes HttpOnly JWT refresh tokens on 401 responses.
Icons are provided by the lucide‑react library.
