### π Getting Started
|
|
|
|
1. **Add Components**: Drag items from the left sidebar onto the canvas
|
|
2. **Connect Nodes**: Drag from the blue circle on the right of a node to the left circle of another
|
|
3. **Edit Properties**: Click any node to see its editable properties on the right panel
|
|
4. **Organize**: Drag nodes around to create a clean workflow layout
|
|
5. **Delete**: Use the β button on nodes or click the red circle on connections
|
|
|
|
### π― Component Types
|
|
|
|
- **π₯ Inputs**: Text fields, file uploads, number inputs
|
|

### Events
|
|
|
|
| name | description |
|
|
|:-----|:------------|
|
|
| `change` | Triggered when the value of the WorkflowBuilder changes either because of user input (e.g. a user types in a textbox) OR because of a function update (e.g. an image receives a value from the output of an event trigger). See `.input()` for a listener that is only triggered by user input. |
|
|
| `input` | This listener is triggered when the user changes the value of the WorkflowBuilder. |
|
|
|
|
|
|
|
|
### User function
|
|
|
|
The impact on the users predict function varies depending on whether the component is used as an input or output for an event (or both).
|
|
|
|
- When used as an Input, the component only impacts the input signature of the user function.
|
|
- When used as an output, the component only impacts the return signature of the user function.
|
|
|
|
The code snippet below is accurate in cases where the component is used as both an input and an output.
|
|
|
|
|
|
|
|
```python
|
|
def predict(
|
|
value: typing.Dict[str, typing.Any][str, typing.Any]
|
|
) -> typing.Dict[str, typing.Any][str, typing.Any]:
|
|
return value
|
|
```
