Code

Node type: code · Version: 1 · Category: Data Author Python, HTML, JavaScript, or CSS in a full editor. This node can change external state or produce an external side effect.

Configuration

Field	Type	Default	What it controls
`language`	string	`"javascript"`	Language used for highlighting, diagnostics, AI-assisted authoring, and optional execution. Values: `python`, `html`, `javascript`, `css`.
`sourceCode`	string	`"// Transform data or provide browser-side JavaScript\n"`	Complete source stored in the workflow. Open Edit code for the full editor and live Problems panel.
`executionMode`	string	`"source"`	Return the source unchanged, or execute supported script languages and wait for their result. Values: `source`, `run`.
`timeoutMs`	number	`30000`	Maximum time for this operation in milliseconds.

Edit code opens a dedicated editor for Python, HTML, JavaScript, and CSS with syntax highlighting, live syntax and basic type diagnostics, line and column locations, and AI-assisted code writing.

Source mode returns the complete file through code without executing it. HTML and CSS always use source mode.

Run mode is available for Python and JavaScript, requires command-execution approval, invokes the installed python or node executable, and waits for completion. Mapped input is available as JSON in SNDBOX_INPUT.
