Nebula Angular Dashboard is a free, open-source Angular 18 admin and dashboard template built with Bootstrap 5, designed for real-time data visualization and enterprise-grade admin interfaces.
What is Nebula Angular Dashboard?
Nebula Angular Dashboard is an enterprise-grade Angular dashboard template inspired by Monster Angular Lite. It takes raw data from WebSocket streams, mock APIs, or static JSON and produces interactive dashboards with charts, data tables, kanban boards, notification centers, and weather widgets. Built on Angular 18 with Bootstrap 5 and optimized for TypeScript strict mode, it's published under the MIT License by SyedaFizaFatima0 on GitHub.
Key Features
- Real-Time Data Engine — Includes a pre-built WebSocket integration layer (
DataStreamService) that updates charts, tables, and widgets without page reloads, with automatic reconnection, buffering, and throttling. - Modular Component Architecture — Every UI element is a standalone Angular module; the tree-shaking friendly pattern reduces bundle size by up to 40% compared to monolithic admin templates.
- Polyglot Interface — Full i18n support with JSON translation files for English, Spanish, French, German, Japanese, and Arabic (RTL), plus a
TranslationGuardthat prefetches language packs on route change. - Adaptive Charting System — Integrates Chart.js 4 with a custom wrapper that adjusts chart resolution to viewport and device pixel ratio; bar charts collapse to donut variants on mobile.
- Enterprise-Grade Authentication — Mock authentication flow with JWT token simulation, role-based access control (Admin, Editor, Viewer), and route guards;
AuthStateServiceuses Angular's signal API for reactive permission checks. - Component Showcase — DataTable (5 variants with column virtualization for 10K+ rows), Kanban Board (3 variants with drag-and-drop), Notification Center (toast, banner, dropdown), Weather Widget (2 variants with GeoIP auto-detection), and Calendar (month, week, agenda).
- ThemeSwitcher — Supports 8 color schemes (Light, Dark, Sepia, High Contrast, Ocean, Forest, Sunset, Midnight) with smooth CSS custom property transitions.
- Performance Budgets — OnPush change detection, virtual scrolling for lists over 100 items, lazy-loaded feature modules, and preconnect hints for CDN resources.
Who is it for?
- Angular developers who need a production-ready dashboard shell without building UI components from scratch; they can import only the modules they need.
- Teams building SaaS backends looking for role-based authentication, a mock JWT flow, and lazy-loaded routing to scaffold an admin panel quickly.
- Data-driven product teams that want to visualize server metrics, financial flows, or user engagement in real time using the included WebSocket data stream and Chart.js wrappers.
What can you do with Nebula Angular Dashboard?
- Build an analytics dashboard: connect a WebSocket feed to the DataStreamService and render live charts, tables, and KPI widgets without page reloads.
- Create a multi-language admin panel: enable i18n across six languages including RTL Arabic, with prefetched translation packs on route changes.
- Prototype a role-based SaaS backend: use the mock JWT authentication, Admin/Editor/Viewer roles, and route guards to demo permissions.
- Customize the visual identity: override 300+ Sass design tokens in
_nebula-theme.scss, swap between 8 color schemes, and adjust border radius, transitions, and accent colors.
How does Nebula Angular Dashboard work?
The template uses Angular's modern features: state management relies on Angular signals plus a lightweight store pattern (RxJS BehaviorSubject), routing uses child routes with lazy loading while the shell layout (sidebar + navbar) is preloaded. To add a new page, create a component in src/app/features/, register the route in app.routes.ts with loadComponent for lazy loading, and add a navigation link in the sidebar's navigation file. Charts are plugin-based: drop a new implementation in src/app/shared/charts/, register it in ChartRegistryService, and use it via the nebula-chart directive.
