| 13 | + |
| 14 | +Node.js CLI runs your Scratch project directly in Node.js environment using scratch-vm. This is intended for server-side execution, automated testing, or batch processing tasks. |
| 15 | + |
| 16 | +Advantages: |
| 17 | + |
| 18 | +- Small file size (~20-30MB vs ~100MB for Electron) |
| 19 | +- Fast startup (no browser overhead) |
| 20 | +- Direct event monitoring |
| 21 | +Command Line Arguments: |
| 22 | + |
| 23 | +You can pass arguments to your application like this: |
| 24 | + |
| 25 | +`app.exe your-project.sb3 --arg1 value1 --arg2 value2 --flag` |
| 26 | + |
| 27 | +CLI API Available: |
| 28 | + |
| 29 | +In CLI mode, you can use the following JavaScript functions in your Scratch project: |
| 30 | + |
| 31 | +- You can use a `say` block to output text to the console |
| 32 | + |
| 33 | +- cli.log(message) - Output text to console |
| 34 | +- cli.error(message) - Output error to console |
| 35 | +- cli.warn(message) - Output warning to console |
| 36 | +- cli.info(message) - Output info to console |
| 37 | +- cli.exit(code) - Exit the application (0 = success, non-zero = error) |
| 38 | +- cli.getArgs() - Get all command line arguments as an object |
| 39 | +- cli.getArg(key) - Get a specific command line argument by key |
| 40 | +Example Usage: |
| 41 | +```javascript |
| 42 | +// Get command line arguments |
| 43 | +const args = cli.getArgs(); |
| 44 | +cli.log('Arguments:', args); |
| 45 | + |
| 46 | +// Get specific argument |
| 47 | +const mode = cli.getArg('mode'); |
| 48 | +if (mode === 'test') { |
| 49 | + cli.log('Running in test mode'); |
| 50 | +} |
| 51 | + |
| 52 | +// Exit with success code |
| 53 | +cli.exit(0); |
| 54 | +Packaging Instructions: |
| 55 | +``` |
| 56 | +After downloading the package: |
| 57 | + |
| 58 | +Extract the ZIP file to a folder |
| 59 | + |
| 60 | +Install Node.js (version 18 or higher) |
| 61 | + |
| 62 | +Open a terminal/command prompt in the extracted folder |
| 63 | + |
| 64 | +Run `npm install` to install dependencies |
| 65 | + |
| 66 | +Run `npm run build` to create the executable |
| 67 | + |
| 68 | +The executable will be created in the same folder |
| 69 | + |
| 70 | +Simply run the executable - no external SB3 file needed! |
| 71 | + |
| 72 | +Important: Node.js CLI mode: |
| 73 | + |
| 74 | +No graphical output - project runs in headless mode |
| 75 | + |
| 76 | +Mouse and keyboard interactions will not work |
| 77 | + |
| 78 | +Audio playback may be limited |
| 79 | + |
| 80 | +Some extensions may not be compatible |
| 81 | + |
| 82 | +Perfect for automated testing, server-side execution, or background tasks |
