Variable

Variable gives a value a name so later nodes on the path can reuse it. Use it for a setting, a message, or a useful part of an earlier result.

Try it step by step#

1. Add name with the value Builder in one Variable node.
2. Connect a second Variable and add greeting with the value Hello, {{name}}!.
3. Run and inspect the second output. Change Builder to another name and compare the next run.

What to expect#

The second node emits {"greeting":"Hello, Builder!"}. Its output contains the variables it creates, while earlier values remain available through expressions on that path.

Things to check#

• Use an exact expression to keep a number, object, or array in its original form. Embedding an expression in a sentence produces text.
• Use separate nodes when one new variable depends on another new variable. Parameters are resolved before a node executes.
• Use State when a value must survive into the next run.
