What is Dash Prism?

Dash Prism provides a unified workspace where multiple Dash layouts coexist as tabs within resizable, splittable panels. Users arrange their workspace via drag-and-drop while developers focus on building content.

The Problem

Building dashboards with Plotly Dash typically means:

• Fragmented applications - Each dashboard lives in isolation, requiring users to switch between browser tabs or navigate complex menus.
• Repetitive UI work - Developers spend time on layout scaffolding, content management, and styling instead of business logic.
• One-size-fits-all layouts - Users get a fixed arrangement that may not match their workflow.
• No personalization - Workspaces reset on every visit; users cannot save their preferred view.

The Solution

Dash Prism addresses these issues by providing:

• Unified workspace - Register any number of layouts; users open them as tabs in a single interface.
• User-driven design - Drag tabs to split panels, resize areas, and rearrange freely. Developers define content; users define structure.
• Persistence - Workspace state saves to localStorage, sessionStorage, or memory so users return to exactly where they left off.
• Minimal boilerplate - A decorator-based API keeps layout registration concise and readable.

Features

• User-Driven Layout - Users style tabs with colors and icons, reorder them freely, and drag to panel edges to split the view. You create the content; they make the dashboard.
• Favorites & Search - Find layouts instantly with the integrated search bar. Mark frequently-used ones as favorites to pin them at the top.
• On-Demand Loading - Tab content loads dynamically when selected, keeping initial page load fast even with many registered layouts.
• Parameterized Layouts - Capture user options before loading a layout, minimizing server round-trips and delivering exactly what the user wants.
• Custom Actions - Add status bar buttons that trigger Dash callbacks for saving workspaces, exporting data, or any custom functionality.
• Persistence & Workspace State - State saves to localStorage, sessionStorage, or memory. Use readWorkspace and updateWorkspace for programmatic backup, restore, or team sharing.
• Context Menus - Right-click tabs to rename, duplicate, lock, style, or generate a shareable link to send a specific tab to someone else.
• Keyboard Shortcuts - Full keyboard navigation: new tab, close, rename, undo close, switch tabs, and more.
• Error Resilience - Errors are captured at the tab level, guarding against crashes that would otherwise take down the workspace.

Light and Dark Mode

Dash Prism supports both light and dark themes, so the workspace adapts to your style.
