String ports

This page will explain how to create an input and output port of the type 'String'


Click this link to see an example of all port types and code examples

JavaScript strings are used for storing and manipulating text
A string is zero or more characters written inside quotes

The following code snippet will create one input and output port of the type String

The input string will be passed out of the output port

//strict mode allows us to write cleaner code
"use strict";

//Create a input port of the type String
const inString  = op.inString("String in");
//Create a output port of the type String
const outString = op.outString("String out");

//when input port changes call the function 'update'
inString.onChange = update;

//this function runs every time the input port changes
function update()
    //if the input type is not a String then output a string instead
    //else set the output to the input string
    else outString.set(inString.get());
