# Understanding Conditional Branching
|
||
|
|
|
||
|
|
Learn how to create workflows that take different paths based on data conditions, making your workflows more intelligent and adaptive.
|
||
|
|
|
||
|
|
## What is Conditional Branching?
|
||
|
|
|
||
|
|
Conditional branching allows workflows to:
|
||
|
|
|
||
|
|
- **Make decisions**: Choose different processing paths based on data
|
||
|
|
- **Handle variations**: Process different content types differently
|
||
|
|
- **Optimize performance**: Skip unnecessary steps for certain inputs
|
||
|
|
- **Customize behavior**: Provide different experiences based on conditions
|
||
|
|
|
||
|
|
## Real-World Example
|
||
|
|
|
||
|
|
Imagine a content processing workflow that:
|
||
|
|
|
||
|
|
- **Short content** (< 50 words): Gets quick processing
|
||
|
|
- **Medium content** (50-200 words): Gets standard processing
|
||
|
|
- **Long content** (> 200 words): Gets detailed processing with extra analysis
|
||
|
|
|
||
|
|
## Basic Branching Syntax
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
.branch([
|
||
|
|
[condition1, step1],
|
||
|
|
[condition2, step2],
|
||
|
|
[condition3, step3]
|
||
|
|
])
|
||
|
|
```
|
||
|
|
|
||
|
|
Where:
|
||
|
|
|
||
|
|
- **condition**: An async function that returns `true` or `false`
|
||
|
|
- **step**: The step to execute if the condition is `true`
|
||
|
|
|
||
|
|
## Condition Functions
|
||
|
|
|
||
|
|
Conditions are functions that examine the input data:
|
||
|
|
|
||
|
|
```typescript
|
||
|
|
// Example condition function
|
||
|
|
async ({ inputData }) => {
|
||
|
|
return inputData.wordCount < 50;
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
## Multiple Paths
|
||
|
|
|
||
|
|
- If multiple conditions are `true`, **all matching steps run in parallel**
|
||
|
|
- If no conditions are `true`, the workflow continues without executing any branch steps
|
||
|
|
- Conditions are evaluated in order, but matching steps run simultaneously
|
||
|
|
|
||
|
|
## Benefits
|
||
|
|
|
||
|
|
- **Smart routing**: Send data down the most appropriate path
|
||
|
|
- **Performance**: Skip expensive operations when not needed
|
||
|
|
- **Flexibility**: Handle different scenarios in one workflow
|
||
|
|
- **Maintainability**: Clear logic for different processing paths
|
||
|
|
|
||
|
|
Next, you'll create a workflow with conditional branches!
