Variable Assigner

The Variable Assigner node serves as a hub for collecting branch outputs within the workflow, ensuring that regardless of which branch is taken, the output can be referenced by a single variable. The output can subsequently be manipulated by nodes downstream.

In the example below, a branch is created to produce different LLM responses based on different user questions: A knowledge base is used in one branch, but not the other. The output variables from both branches are squashed by a Variable Assigner node into a single output based on the branch taken. This has a few benefits:

1. Avoids having to create duplicate downstream logic for each branch

2. When modifying the name of an output variable, you don't need to locate everywhere it is referenced downstream and update the variable name.

Variable Assigner supports multiple types of output variables including String,Number, Object, and Array. Given the specified output type, you may add input variables from the dropdown list of variables to the node. The list of variables is derived from previous branch outputs and autofiltered based on the specified type.

Variable Assigner gives a single output variable of the specified type for downstream use.
