Debugging Mermaid Diagrams 2 | 3 | This guide helps you diagnose and fix issues with Mermaid diagram rendering in the Crabwalk web visualizer. 4 | 5 | ## Common Error: "Cannot read properties of null (reading 'firstChild')" 6 | 7 | This error typically occurs when: 8 | 1. The Mermaid library cannot parse the diagram content 9 | 2. The DOM element for rendering isn't properly set up 10 | 3. There's a race condition in the rendering process 11 | 12 | ## How to Debug 13 | 14 | ### 1. Use the Test Page 15 | 16 | We've created a standalone test page to isolate and debug Mermaid rendering: 17 | 18 | ```bash 19 | # Run the Mermaid test page 20 | cd /Users/mritchie712/blackbird/yato-main/crabwalk/crabwalk-web 21 | ./scripts/debug_mermaid.sh 22 | ``` 23 | 24 | This will open a browser with a test page that: 25 | - Shows multiple test cases for Mermaid diagrams 26 | - Displays detailed error messages 27 | - Allows you to test both valid and invalid content 28 | 29 | ### 2. Check Your Diagram Content 30 | 31 | If you're seeing errors with a specific diagram: 32 | 33 | 1. Copy the problematic diagram content 34 | 2. Start the test page (as shown above) 35 | 3. Add a new test case with your content 36 | 4. Look for syntax errors in the Mermaid content 37 | 38 | ### 3. Fix Options 39 | 40 | The most reliable way to fix Mermaid rendering issues is to: 41 | 42 | 1. Import Mermaid directly rather than dynamically loading it 43 | 2. Use the render method with a unique ID 44 | 3. Directly use the returned SVG content 45 | 4. Add robust error handling 46 | 47 | ## Current Implementation 48 | 49 | The current implementation in `src/components/MermaidDiagram.tsx` has been updated to: 50 | 51 | 1. Use a proper render loop with state management 52 | 2. Properly handle errors and display them 53 | 3. Use unique IDs for each rendering 54 | 4. Show a loading state during processing 55 | 56 | ## Testing Your Own Diagrams 57 | 58 | To test your specific diagrams: 59 | 60 | 1. Edit `src/test/MermaidTest.tsx` 61 | 2. Add your diagram content to the `samples` array 62 | 3. Run the test script 63 | 4. Check the output and error messages 64 | 65 | ## Getting Additional Help 66 | 67 | If you continue to have issues: 68 | 69 | 1. Check Mermaid's official syntax guide: https://mermaid.js.org/intro/ 70 | 2. Look at Mermaid's live editor: https://mermaid.live/ 71 | 3. Try simplifying your diagram to identify problem areas 72 | 73 | ## Known Limitations 74 | 75 | - Very complex diagrams might be slow to render 76 | - Some advanced features may not be supported 77 | - Auto-generated connections work best with standard naming conventions -------------------------------------------------------------------------------- /crabwalk-web/README.md: -------------------------------------------------------------------------------- 1 | # Crabwalk Web 2 | 3 | A web interface for the Crabwalk SQL transformation orchestrator. 4 | 5 | ## Getting Started 6 | 7 | ```bash 8 | # Install dependencies 9 | npm install 10 | 11 | # Start development server 12 | npm run dev 13 | 14 | # Build for production 15 | npm run build 16 | 17 | # Start production server 18 | npm run start 19 | ``` 20 | 21 | ## Build and Run After Making Changes 22 | 23 | When you make changes to the codebase, follow these steps to build and run the application: 24 | 25 | ```bash 26 | # Compile TypeScript and build the application 27 | npm run build 28 | 29 | # Start the server with the updated build 30 | npm run server 31 | 32 | # Or, build and start in one command 33 | npm run start 34 | ``` 35 | 36 | The build process will: 37 | 1. Compile TypeScript (`tsc -b`) 38 | 2. Build the frontend with Vite (`vite build`) 39 | 3. Compile server TypeScript (`tsc -p tsconfig.server.json`) 40 | 41 | After building, the application will be available at http://localhost:3000 (or the configured port). 42 | 43 | ## Relationship with Cargo/Rust App 44 | 45 | This web interface is a companion to the main Crabwalk CLI tool, which is built with Rust/Cargo and located in the parent directory. To build and use both components: 46 | 47 | ### Building the Rust CLI 48 | 49 | Navigate to the parent directory and build the Rust application: 50 | 51 | ```bash 52 | # From the crabwalk-web directory 53 | cd .. 54 | 55 | # Build the Rust CLI 56 | cargo build --release 57 | 58 | # Run examples with the Rust CLI 59 | cargo run 60 | ``` 61 | 62 | ### Using Both Together 63 | 64 | The web application can visualize projects created by the Rust CLI. A typical workflow: 65 | 66 | 1. Use the Rust CLI to process SQL files and generate schema/lineage information: 67 | ```bash 68 | cargo run -- run ./path/to/sql/files 69 | ``` 70 | 71 | 2. Run the web application to visualize the output: 72 | ```bash 73 | npm run start 74 | ``` 75 | 76 | 3. Or use the CLI command to launch the web interface directly: 77 | ```bash 78 | cargo run -- app --open 79 | ``` 80 | 81 | ## Troubleshooting 82 | 83 | ### Perspective WebAssembly Setup 84 | 85 | The application uses Perspective.js for data visualization, which requires WebAssembly files. We've implemented a robust solution to ensure all WebAssembly files are correctly loaded: 86 | 87 | 1. **WebAssembly File Management**: 88 | - A script (`scripts/setup-wasm.js`) copies necessary WebAssembly files from node_modules to the `public/wasm` directory 89 | - The script also creates aliases for the WebAssembly files with alternative names that Perspective might look for 90 | - This includes specific handling for `perspective-client.wasm` which is required but not directly provided 91 | 92 | 2. **Path Configuration**: 93 | - We inject WebAssembly paths into the window object in the HTML files 94 | - This ensures Perspective can find the WebAssembly files even when using different naming conventions 95 | - We use `window.PERSPECTIVE_ASSETS` to specify exact paths for each WebAssembly file 96 | 97 | 3. **Testing Perspective**: 98 | - A dedicated test component (`/src/test/PerspectiveTest.tsx`) verifies WebAssembly loading 99 | - Run `npm run test:perspective` to check if Perspective is working correctly 100 | - This helps diagnose WebAssembly loading issues independently of the main application 101 | 102 | If you encounter errors like "Missing perspective-client.wasm": 103 | 104 | 1. Check that all WebAssembly files and aliases were created: 105 | ```bash 106 | npm run setup-wasm 107 | ls -la public/wasm 108 | ``` 109 | 110 | 2. Make sure your server has the correct CORS headers: 111 | ``` 112 | Cross-Origin-Opener-Policy: same-origin 113 | Cross-Origin-Embedder-Policy: require-corp 114 | ``` 115 | 116 | 3. Try clearing browser cache and storage: 117 | - Clear browser cache 118 | - Clear IndexedDB and WebAssembly storage 119 | - Restart your browser 120 | 121 | 4. Check for console errors about disallowed WebAssembly features: 122 | - Some browsers restrict WebAssembly features 123 | - Ensure SharedArrayBuffer is available and allowed 124 | 125 | ### DuckDB WebAssembly Implementation 126 | 127 | The application uses DuckDB-wasm to provide SQL database capabilities directly in the browser. Here's how it works: 128 | 129 | 1. **WebAssembly Loading**: DuckDB is compiled to WebAssembly, which runs in the browser with near-native performance. 130 | 131 | 2. **Web Worker**: DuckDB runs in a dedicated Web Worker thread to avoid freezing the UI during intensive operations. 132 | 133 | 3. **Blob URL Creation**: We use a Blob URL to create the worker, which resolves cross-origin issues and provides better compatibility across browsers. 134 | 135 | 4. **Memory Database**: By default, an in-memory database is created, and you can load external database files. 136 | 137 | If you encounter any issues: 138 | 139 | 1. **Clear Browser Cache**: Clear your browser cache and reload the application. 140 | 141 | 2. **Use a Modern Browser**: Ensure you're using a recent version of Chrome, Firefox, Edge, or Safari. 142 | 143 | 3. **Check Console Logs**: Open your browser developer tools (F12) to check for error messages. 144 | 145 | 4. **WebAssembly Support**: Your browser must support WebAssembly. All modern browsers support this feature. 146 | 147 | 5. **Cross-Origin Issues**: When running locally, use a proper web server (like the Vite dev server) rather than opening the HTML file directly. 148 | 149 | ### Using Example Files 150 | 151 | Example database files are available in the `examples` directory of the Crabwalk project. Try loading these files first to ensure the application is working correctly. -------------------------------------------------------------------------------- /crabwalk-web/bin/crabwalk-web.js: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env node 2 | 3 | // CLI entry point for crabwalk-web 4 | // This allows users to run 'crabwalk-web' from any directory 5 | // to visualize their Crabwalk project 6 | 7 | import { spawn } from 'child_process'; 8 | import path from 'path'; 9 | import { fileURLToPath } from 'url'; 10 | import fs from 'fs'; 11 | 12 | const __filename = fileURLToPath(import.meta.url); 13 | const __dirname = path.dirname(__filename); 14 | const rootDir = path.resolve(__dirname, '..'); 15 | 16 | console.log('🦀 Starting Crabwalk Web Visualizer...'); 17 | console.log('Scanning for project files in current directory...'); 18 | 19 | // Build the app if dist directory doesn't exist 20 | if (!fs.existsSync(path.join(rootDir, 'dist'))) { 21 | console.log('Building application (one-time process)...'); 22 | 23 | const buildProcess = spawn('npm', ['run', 'build'], { 24 | cwd: rootDir, 25 | stdio: 'inherit', 26 | }); 27 | 28 | buildProcess.on('close', (code) => { 29 | if (code !== 0) { 30 | console.error('Error building application.

-------------------------------------------------------------------------------- 1 | # Jaffle Shop Example for Crabwalk 2 | 3 | This is a Crabwalk implementation of the popular "Jaffle Shop" example, which demonstrates a simple ELT workflow processing customer orders for a fictional restaurant. 4 | 5 | ## Structure 6 | 7 | The example is organized in three layers: 8 | 9 | 1. **Sources** - Raw data loaded from CSV files: 10 | - `raw_customers.sql` - Customer information 11 | - `raw_orders.sql` - Order details 12 | - `raw_products.sql` - Product catalog 13 | - `raw_stores.sql` - Store locations 14 | - `raw_supplies.sql` - Supplies inventory 15 | - `raw_items.sql` - Order items 16 | 17 | 2. **Staging** - Lightly transformed data with renamed columns and improved types: 18 | - `stg_customers.sql` - Cleaned customer data 19 | - `stg_orders.sql` - Cleaned order data 20 | - `stg_products.sql` - Cleaned product data 21 | - `stg_locations.sql` - Cleaned store location data 22 | - `stg_supplies.sql` - Cleaned supplies data 23 | - `stg_order_items.sql` - Cleaned order items 24 | 25 | 3. **Marts** - Business-focused models combining multiple sources: 26 | - `customers.sql` - Customer profile with order history 27 | - `orders.sql` - Order details with customer information 28 | - `products.sql` - Product details 29 | - `locations.sql` - Store locations 30 | - `supplies.sql` - Supply inventory 31 | - `order_items.sql` - Order items with product details 32 | 33 | ## Running the Example 34 | 35 | To run the Jaffle Shop example: 36 | 37 | ```bash 38 | ./run-jaffle 39 | ``` 40 | 41 | This script will: 42 | 1. Create a fresh database 43 | 2. Process source files (loading from CSVs) 44 | 3. Process staging files (transforming raw data) 45 | 4. Process mart files (creating business models) 46 | 5. Display a summary of all created tables 47 | 48 | ## Exploring the Data 49 | 50 | After running the example, you can explore the data using DuckDB: 51 | 52 | ```bash 53 | duckdb crabwalk.db 54 | ``` 55 | 56 | Example queries: 57 | 58 | ```sql 59 | -- View all customers 60 | SELECT * FROM customers; 61 | 62 | -- View orders with customer details 63 | SELECT o.order_id, o.order_date, c.customer_name 64 | FROM orders o 65 | JOIN customers c ON o.customer_id = c.customer_id 66 | LIMIT 10; 67 | 68 | -- View order items with product details 69 | SELECT oi.order_id, oi.product_id, p.product_name, oi.quantity 70 | FROM order_items oi 71 | JOIN products p ON oi.product_id = p.product_id 72 | LIMIT 10; 73 | ``` 74 | 75 | ## Notes 76 | 77 | - This example includes some circular dependencies between models to demonstrate how to handle them in Crabwalk. 78 | - The lineage feature may show errors for file paths, but this doesn't affect the data processing. 79 | - All tables are created in the `crabwalk.db` DuckDB database. -------------------------------------------------------------------------------- /examples/jaffle_shop/config.json:
