# ComfyUI Simple Variables
|
|
|
|
A lightweight custom node pack for ComfyUI that provides **Set/Get variable nodes** for storing and retrieving any data by name across your workflow.
|
|
|
|
## Installation
|
|
|
|
```bash
|
|
cd ComfyUI/custom_nodes
|
|
git clone https://github.com/jessesep/ComfyUI-SimpleVariables.git
|
|
```
|
|
|
|
Restart ComfyUI and search for **"variable"** in the node menu.
|
|
|
|
## Nodes
|
|
|
|
| Node | Description | Category |
|
|
|------|-------------|----------|
|
|
| **Set Variable** | Store any data with a custom name | `variables` |
|
|
| **Get Variable** | Retrieve stored data by name | `variables` |
|
|
| **List Variables** | Show all stored variables | `variables` |
|
|
|
|
## Usage
|
|
|
|
### Basic Example
|
|
|
|
```
|
|
[Load Image] → [Set Variable] (name: "reference")
|
|
↓
|
|
(passes through)
|
|
|
|
... elsewhere in workflow ...
|
|
|
|
[Get Variable] (name: "reference") → [Any Node]
|
|
```
|
|
|
|
### How It Works
|
|
|
|
1. **Set Variable** stores any input data with your chosen variable name
|
|
2. Data passes through, so you can continue your workflow normally
|
|
3. **Get Variable** retrieves stored data anywhere by name
|
|
4. Works with ALL ComfyUI data types: Image, Mask, Latent, Model, CLIP, VAE, Conditioning, String, Int, Float, and custom types
|
|
|
|
### Tips
|
|
|
|
- Use descriptive names like `"upscaled_image"` or `"final_mask"`
|
|
- **List Variables** helps debug what's currently stored
|
|
- Variables persist for the ComfyUI session (cleared on restart)
|
|
- If a variable doesn't exist, you'll see available variable names in the error
|
|
|
|
## Why Use This?
|
|
|
|
- **Reduce wire clutter** - "Wireless" data transfer across your workflow
|
|
- **Reuse outputs** - Store once, use multiple times
|
|
- **Simplify complex workflows** - No more spaghetti connections
|
|
- **Universal** - One node handles all data types
|
|
|
|
## Deprecated Nodes
|
|
|
|
Type-specific nodes (Set Image Variable, Set Mask Variable, etc.) are available under `variables/deprecated` for backward compatibility, but **Set/Get Variable handles all types** so they're no longer needed.
