Custom conponent - yes/no operator

[bro-xuan]

How do I write a component that acts as a "yes" or "no" operator, that if text input is "True", then pass the value to next component, if "FALSE" then end

Hey @bro-xuan! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's tackle this together!

To create a custom component that acts as a "yes" or "no" operator, passing the value to the next component if the input is "True" and ending the process if the input is "False", you can use the following code as a reference:

from langflow.custom import Component
from langflow.io import BoolInput, MessageTextInput, Output
from langflow.schema.message import Message

class YesNoOperatorComponent(Component):
    display_name = "Yes/No Operator"
    description = "Passes the value if the input is True, ends the process if the input is False."
    icon = "toggle-on"

    inputs = [
        BoolInput(
            name="input_value",
            display_name="Input Value",
            info="Boolean input to evaluate.",
        ),
        MessageTextInput(
            name="value_to_pass",
            display_name="Value to Pass",
            info="The value to pass if the input is True.",
        ),
    ]

    outputs = [
        Output(display_name="Passed Output", name="passed_output", method="pass_through"),
    ]

    def pass_through(self) -> Message:
        input_value = self.input_value
        value_to_pass = self.value_to_pass

        if input_value:
            self.status = value_to_pass
            return Message(text=value_to_pass)
        else:
            self.stop()
            return Message()

This component evaluates the boolean input value. If the input is True, it passes the specified value; otherwise, it stops the process ^{[1][2][3][4][5]}.
