Waffle Board

A JSON schema-based dashboard renderer for React. Build complex, draggable grid layouts simply by defining a JSON configuration.

Features

• JSON-Driven: Define your entire dashboard layout and widget configuration in a simple JSON object.
• Drag & Drop: Built-in support for resizing and rearranging widgets (powered by react-grid-layout).
• Theme System: 4 distinct themes (Ocean, Forest, Sunset, Default) with dark mode support.
• Waffle Charts Integration: Showcases the full power of the Waffle Charts library.
• Modern UI: Clean aesthetics using Tailwind CSS and Lucide icons.

Tech Stack

• Framework: React + Vite
• Language: TypeScript
• Styling: Tailwind CSS
• Charts: Waffle Charts (Visx-based)
• Grid: react-grid-layout

Installation (As a Library)

waffle-board can now be installed as an NPM package to power your own dashboards.

npm install waffle-board

Basic Usage

import { Dashboard } from 'waffle-board';
import { BarChart } from '@waffle-charts/components/waffle/BarChart';
import { LineChart } from '@waffle-charts/components/waffle/LineChart'; // Your chart components
import 'waffle-board/dist-lib/style.css'; // Import styles

const registry = {
  'my-bar-chart': BarChart,
  'my-line-chart': LineChart
};

function MyDashboard() {
  return (
    <Dashboard 
      config={myConfig} 
      registry={registry}
      isEditable={true} 
    />
  );
}

Note: The Vite config in this repo defines an alias @waffle-charts that points to the local source of the waffle-charts library. This lets you import chart components directly from their file paths.

Supported Charts

Directly import these components from @waffle-charts/components/waffle/:

• BarChart - Supports stacked and grouped variants
• LineChart - Supports multi-series and legends
• AreaChart
• PieChart
• CandlestickChart - Financial OHLC data
• ScatterChart
• RadarChart
• HeatmapChart
• TreemapChart
• SankeyChart
• ChordChart

Registry Explanation

The registry object maps the string type found in your JSON configuration (e.g., "type": "my-bar-chart") to the actual React component. This allows the JSON schema to remain serializable and agnostic of implementation details.

Data Integration (Dynamic Loading)

Widgets can fetch their own data by defining a dataSource in the JSON config. You provide the fetcher implementation.

<Dashboard
  // ...
  fetcher={async (dataSource) => {
    // Implement your data fetching logic here
    if (dataSource.type === 'api') {
      const response = await fetch(dataSource.endpoint);
      return response.json();
    }
    return null;
  }}
/>

Running the Project

Demo App

To run the included demo application:

npm run dev

Building the Library

To build the distributable library bundle (dist-lib/):

npm run build:lib

Theme Customization

Themes are defined in src/index.css using CSS variables. To add a new theme:

1. Add a new .theme-name class in index.css.
2. Define the color palette (background, foreground, primary, etc.).
3. Add the theme to the themes array in src/App.tsx.

Troubleshooting

• Module not found: Verify the @waffle-charts alias exists in vite.config.ts.
• TypeScript errors: Run npm run build:lib to generate the compiled type definitions.
