Text & Output Nodes

Nodes for providing text, formatting output, and logging.


Text Input

Provides a static text value as output. This is the simplest starting point for most workflows — enter text in the configuration panel and it flows to the next node.

Category: Text & Output

Configuration

Parameter Type Required Description
defaultValue String No The text value to output

Input Ports

Port Type Description
data Mixed Optional dynamic input that overrides the default value

Output Ports

Port Type Description
text String The text value

Usage

Use Text Input as a starting node when you want to provide a fixed text value. The value set in the configuration panel is used unless data arrives through the data input port, which overrides it.


Text Output

Outputs text with optional length limits and format selection.

Category: Text & Output

Input Ports

Port Type Required Description
text String Yes The text to output

Configuration

Parameter Type Default Description
maxLength Number (none) Maximum character length — text will be truncated if exceeded
format String plain Output format: plain, html, or markdown

Output Ports

Port Type Description
text String The processed text
length Number Character count of the output text

Prompt Template

Renders a text template with variable substitution using Twig syntax. The most common usage is {{ variable_name }} for simple substitution, but the full Twig template language is supported (filters, conditionals, loops, etc.).

Category: Text & Output

Configuration

Parameter Type Required Description
template String Yes Twig template text with {{ variable }} placeholders

Input Ports

Port Type Description
variables Mixed Dynamic variables that replace template placeholders

Each {{ variable_name }} in the template creates a corresponding input port. Connect data to these ports to substitute values at runtime.

Output Ports

Port Type Description
prompt String The rendered template with all variables replaced
template String The original template string
variables Mixed The variable values that were substituted

Example

Template: Hello {{ name }}, you have {{ count }} new messages.

If name = "Alice" and count = "3", the output is: Hello Alice, you have 3 new messages.

Since this uses Twig, you can also use filters and logic:

  • {{ name|upper }} — Converts to uppercase
  • {{ count + 1 }} — Arithmetic expressions
  • {% if count > 0 %}You have mail{% endif %} — Conditionals

Chat Input

Accepts chat messages for interactive workflows in the Playground. Provides the user's message along with conversation history.

Category: Text & Output

Output Ports

Port Type Description
message String The user's message text
history Array Previous messages in the conversation
sessionId Number The session identifier
messageId Number The message identifier
