⚙️ App Functions Configuration

App Functions enable you to create custom reusable functions that can be called within workflows to perform specific logic or calculations.

---

Configuration Fields

• Name Enter a unique name for your function to identify it within your workflow system.

---

Params

Define the input parameters that your function accepts:

Field	Description
Parameter Name	Name of the parameter (e.g., "Initial Node")
Type	Data type of the parameter (e.g., string, number, boolean)
Initial Value	Default value assigned to the parameter
Expression	(Optional) Use expressions or formulas to compute the value dynamically

Use the + button to add more parameters or the trash icon to remove existing ones.

---

Return Types

Specify the data types and values your function returns:

Field	Description
Return Name	Name for the return value (e.g., "Initial Node")
Type	Data type of the return value
Initial Value	Default return value
Expression	(Optional) Expression to dynamically determine the return value

Add or remove return values similarly with + and trash buttons.

---

Example Use Cases

• Calculating derived data or metrics.
• Transforming input values for other workflow steps.
• Performing conditional logic within a reusable function.

---

Example: Function Definition

function calculateDiscount(price, discountRate) {
  // Parameters
  // price: Number - original price
  // discountRate: Number - discount percentage (0-100)

  const discount = (price * discountRate) / 100;
  const finalPrice = price - discount;

  // Return result as an object
  return {
    discountAmount: discount,
    finalPrice: finalPrice,
  };
}

Best Practices

• Clearly name parameters and return types for easier reuse.
• Use expressions to make your function dynamic and flexible.
• Keep functions focused on a single logical task.

This feature empowers you to modularize complex logic and reuse it across multiple workflows, improving maintainability and reducing redundancy.
