Modern Enterprise Admin Dashboard
High-Performance Real-Time Analytics
Angular 21 & Signals TypeScript 5.9 Tailwind CSS 4 Vitest (JSDOM) Chart.js (ng2-charts) Lucide Icons (Tree-shaken)
The Challenge
Enterprise dashboards often collapse under scale: "spaghetti code," slow real-time rendering, and brittle test suites that block delivery. The goal was to define a production-grade reference architecture that stays fast and maintainable as data volume and feature complexity grow.
The Solution
I built a modern Angular application using Signals to keep state changes predictable and UI updates fine-grained. A Tailwind CSS 4 design system supports dense data layouts without UI bloat, and Vitest enables fast, reliable feedback loops so teams can ship with confidence.
The architecture follows a strictly typed, feature-based modular structure using Angular 21 Standalone Components. We employed a hybrid state management strategy: Angular Signals for synchronous, fine-grained UI state (like filters and toggles) to ensure instant feedback, and RxJS for complex asynchronous data orchestration (WebSockets and API streams). This "Zoneless-ready" approach allows for sub-second updates without triggering global change detection cycles. Testing is handled exclusively via Vitest in JSDOM, providing instant feedback loops.
