I'll enhance the README with more detailed documentation, configuration options, and better examples:

FireCMS Data Export Plugin

This plugin enables exporting Firestore collections to CSV or JSON formats directly from your FireCMS interface. It adds an export button to collection views, providing a simple way to back up data or share it with others.

Installation

npm install @firecms/data_export
# or
yarn add @firecms/data_export

Features

• Export collection data to CSV or JSON formats
• Configure export permissions based on collection size or custom logic
• Integration with FireCMS analytics events
• Custom UI for unsupported export scenarios

Basic Usage

import React from "react";
import { FireCMS } from "@firecms/core";
import { useExportPlugin } from "@firecms/data_export";


export default function App() {

    // Basic setup with default options
    const exportPlugin = useExportPlugin();
    
    const plugins = [exportPlugin];
    
    const navigationController = useBuildNavigationController({
        // ... rest of your config
        plugins
    }); 
    
    return <FireCMS
        name={"My Online Shop"}
        navigationController={navigationController}
        authentication={myAuthenticator}
        collections={myCollections}
        firebaseConfig={firebaseConfig}
    />;
}

Advanced Configuration

You can customize the export behavior with these options:

const exportPlugin = useExportPlugin({
    // Control when exports are allowed
    exportAllowed: ({ collectionEntitiesCount, path, collection }) => {
        // Prevent export of large collections
        if (collectionEntitiesCount > 5000) return false;
        
        // Only allow export for specific collections
        return ["products", "orders"].includes(path);
    },
    
    // Custom view when export is not allowed
    notAllowedView: <div>Export is not available for this collection</div>,
    
    // Track export events
    onAnalyticsEvent: (event, params) => {
        console.log("Export event:", event, params);
    }
});

Configuration Options

Where ExportAllowedParams includes:

• collectionEntitiesCount: Number of entities in the collection
• path: Path of the collection
• collection: Collection configuration object

Additional Notes

• Exports are performed client-side and may be limited by browser capabilities for very large collections
• CSV exports maintain data types where possible but complex objects may be simplified
• JSON exports preserve the complete data structure
