# Loader

### **Overview**

The **Loader Node** in UPTIQ Workbench is designed to **enhance user experience** by displaying a **processing message** when a workflow involves a **time-consuming operation**.

When workflows require **retrieving external data, running computations, or executing multi-step processes**, the **Loader Node** ensures that users are **aware of ongoing activity** rather than experiencing delays with no feedback.

This helps to **reduce user frustration, improve engagement, and create a smoother conversational flow** by keeping users informed during system processing.

### **Configurations**

| Field    | Description                                                                                                                                                                     |
| -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Text** | The message displayed to the user while the process is ongoing. It should be **concise, clear, and informative** to ensure the user understands the system is actively working. |

#### **Best Practices for Loader Messages:**

✅ Keep messages **short and direct** to avoid unnecessary user confusion.\
✅ Use **clear phrasing** to indicate that the process is **in progress** and will complete soon.\
✅ Avoid vague terms like *“Processing…”*—instead, provide context such as *“Retrieving loan details, please wait…”*

### **Example Use-Cases**

#### **1. Indicating Data Retrieval from an External API**

A financial assistant workflow fetches **credit score details** from an external API. Since this **might take a few seconds**, the Loader Node is used to **notify the user** while waiting for the API response.

* **Configuration:**
  * **Text:** `"Fetching your credit score, please wait..."`
* **Outcome:**
  * The message **displays to the user** while the API retrieves the data.
  * Once the API call is completed, the workflow proceeds to display the credit score.

#### **2. Handling a Long Computation for Risk Assessment**

A workflow in a **loan approval system** performs **a complex risk analysis**, which involves checking multiple financial parameters.

* **Configuration:**
  * **Text:** `"Analyzing financial data, this may take a moment..."`
* **Outcome:**
  * The user remains informed that the system is **processing their risk assessment**.
  * The workflow seamlessly continues once computation completes.

### **Key Takeaways for Developers**

✅ **Improves User Experience** – Prevents confusion by clearly informing users that their request is being processed.

By incorporating the **Loader Node**, developers can **manage user expectations, enhance workflow responsiveness, and create AI-driven interactions that feel fluid and natural**. 🚀
