​
Set

The Set node allows you to create and assign values to variables within a spell. Variables can store data that you want to use later in the spell or pass between different nodes.

​
Inputs

  • flow (required): The flow from the previous node in the spell.

​
Outputs

  • flow: The flow continues to the next node in the spell, with the variables set.

​
Configuration

  • variableNames: An array of variable names to create. Enter the desired variable names here.

​
Usage

  1. Add the Set node to your spell.
  2. In the node configuration, enter the names of the variables you want to create in the variableNames array.
  3. Connect the input flow from the previous node to the Set node’s flow input.
  4. Connect the Set node’s flow output to the next node in your spell.
  5. The variables will now be available to use in subsequent nodes within the spell.

​
Example

Let’s say you want to create two variables, userName and userAge, to store information about a user. Here’s how you would use the Set node to accomplish this:
  1. Add the Set node to your spell.
  2. In the variableNames configuration, enter ["userName", "userAge"].
  3. Connect the input flow to the Set node.
  4. In a later node, such as an HTTP Request node, you can reference these variables using {{userName}} and {{userAge}} in the URL or body.

​
Best Practices

  • Give your variables descriptive names that reflect their purpose to keep your spell organized and maintainable.
  • If you need to create many variables, consider using multiple Set nodes to group related variables together logically.

​
Common Issues

  • Forgetting to connect the input flow to the Set node will result in the variables not being created and available in the spell.
  • If you try to reference a variable that hasn’t been created with the Set node, you’ll get an error when running the spell.
