How to Store Temporary Variables as Global Variables?

[rmqrmqrmq]

Sometimes, such as when using LLM for intent classification, the LLM output is maybe just a classification value and the user's original query might be lost. It is necessary to store certain variables as global variables so they can be used in subsequent processes. How can this be achieved? (I tried using combine text to solve this, but it didn’t work because it caused all conditions to be executed simultaneously.)

Hey there, @rmqrmqrmq! I'm here to help you out. If you have any bugs, questions, or want to become a contributor, feel free to ask me.

To store temporary variables as global variables and retain LLM output for intent classification, you can use the useGlobalVariablesStore in Langflow. This allows you to manage global variables effectively. Here's how you can do it:

1. Set Global Variables: Use the setGlobalVariables method to store the LLM output as global variables. This ensures the variables are available for subsequent processes.

   useGlobalVariablesStore.getState().setGlobalVariables({
     intentOutput: { id: 'someId', type: 'someType' }
   });

2. Add a Global Variable: If you need to add a new variable, use the addGlobalVariable method. This lets you add a variable with a specific name, id, and type.

   useGlobalVariablesStore.getState().addGlobalVariable('newIntent', 'newId', 'newType');

3. Retrieve a Variable ID: To get the ID of a specific variable, use the getVariableId method.

   const variableId = useGlobalVariablesStore.getState().getVariableId('intentOutput');

4. Remove a Global Variable: If you need to remove a variable, use the removeGlobalVariable method to ensure unnecessary variables do not persist.

   useGlobalVariablesStore.getState().removeGlobalVariable('intentOutput');

These methods help manage global variables without causing all conditions to execute simultaneously, as each method call updates the store independently ^[1][2].
