creating-dashboards

Use Tremor for pre-built KPI cards, metrics, and charts with minimal code, or compose custom widgets with a grid layout. Wrap the dashboard in a filter context so date ranges and categories update all widgets together.

Tremor provides pre-styled dashboard components for quick analytics interfaces, while react-grid-layout provides drag-and-drop, resizable widget grids for user-customizable layouts. They can be combined: Tremor for widget content, react-grid-layout for positioning.

Use Server-Sent Events for unidirectional server-to-dashboard updates, WebSockets when the dashboard must send commands back, or smart polling as a fallback. Smart polling should pause when document.hidden is true to avoid wasted requests.

Create a global filter context holding date range, categories, and regions, then have every widget read filters from that context and refetch when they change. Debounce filter updates and cache results per filter combination to avoid excessive requests.

Common causes are sequential data fetching, missing lazy loading, and refetching identical data. Fetch widget data in parallel with Promise.all, lazy-load off-screen widgets with skeleton placeholders, and cache widget data with a TTL.

Yes. With react-grid-layout, capture the layout in onLayoutChange and persist it to localStorage, then reload it on mount. The Skill's customizable dashboard example demonstrates save, restore, and reset behavior.
