Commands
| Command | Description |
|---|---|
/creo image-generation generate |
Generate all images using DALL-E 3 |
/creo image-generation generate --seo-only |
Generate only SEO/OG images |
/creo image-generation generate --optimize-only |
Optimize existing images (resize, compress) |
/creo image-generation estimate |
Show cost estimation without generating |
/creo image-generation optimize |
Optimize all images in output directory |
/creo image-generation comfyui |
Generate images using local ComfyUI (SDXL) |
/creo image-generation comfyui landing |
Generate only landing page images via ComfyUI |
How It Works
DALL-E 3 (Cloud)
- Reads image configuration from
paths.js(or uses defaults) - Loads prompts from a
prompts.jsfile (set viaPROMPTS_FILEenv var) - Generates images via the OpenAI DALL-E 3 API
- Skips images that already exist on disk
- Optionally generates SEO overlay images
- Optimizes all images (resize, compress with sharp)
ComfyUI (Local)
- Requires a running ComfyUI instance (see
comfyui/SETUP.md) - Sends workflows to ComfyUI via its REST/WebSocket API
- Uses Stable Diffusion XL models for photorealistic output
- Supports batch generation by category
Environment Variables
| Variable | Required | Description |
|---|---|---|
OPENAI_API_KEY |
Yes (DALL-E) | OpenAI API key for DALL-E 3 generation |
IMAGE_CONFIG_DIR |
No | Directory containing paths.js config |
IMAGE_OUTPUT_DIR |
No | Output directory for generated images |
PROMPTS_FILE |
No | Path to prompts.js with generation prompts |
APP_NAME |
No | Application name for SEO image overlays |
COMFYUI_URL |
No | ComfyUI server URL (default: http://127.0.0.1:8000) |
Cost Reference (DALL-E 3)
| Quality | Size | Cost per Image |
|---|---|---|
| Standard | 1024x1024 | $0.040 |
| HD | 1792x1024 | $0.080 |
Always run --estimate first to review costs before generating.
Library Reference
The extension code lives in the lib/ directory:
lib/ImageGenerator.js-- Main generator class. Handles DALL-E 3 API calls, SEO image generation, and optimization.lib/PathManager.js-- Manages image path generation from configuration. Supports dynamic config parsing.lib/ConfigParser.js-- Parses TypeScript image configuration files to extract categories and image types.lib/utils.js-- Utility functions: file existence checks, cost calculation, file stats, sleep.comfyui/generate-batch.js-- ComfyUI batch generator. Sends workflows via WebSocket, supports category filtering.
Usage Examples
Generate with cost estimate first
# Check cost
node index.js generate --estimate
# Generate all
OPENAI_API_KEY=sk-... node index.js generate
# Generate HD quality
OPENAI_API_KEY=sk-... node index.js generate --quality=hd
ComfyUI local generation
# Start ComfyUI first, then:
node comfyui/generate-batch.js
node comfyui/generate-batch.js landing
node comfyui/generate-batch.js features audio
Optimize existing images
node index.js generate --optimize-only
