A simple Node-RED node with an example
@optyne/node-red-contrib-2j4y7k4 A simple Node-RED node that converts input text to uppercase, with an included example flow.
Overview This package provides a custom Node-RED node called my-example. The node takes an input message, converts the msg.payload to uppercase, and passes it along the flow. It also includes an example flow to demonstrate its usage.
Installation Prerequisites Node-RED must be installed and running on your system. Node.js and npm should be installed. Install via Node-RED Palette Open your Node-RED editor (e.g., http://localhost:1880). Go to the menu (top-right) and select Manage Palette. In the Install tab, search for @optyne/node-red-contrib-2j4y7k4. Click Install and wait for the process to complete. Restart Node-RED if prompted. Install via Command Line Navigate to your Node-RED user directory (default is ~/.node-red on Unix-like systems or %userprofile%.node-red on Windows). bash

Connect it to an input node (e.g., inject) and an output node (e.g., debug). Deploy your flow. Send a message through the node, and it will convert the msg.payload to uppercase. Node Properties Name: (Optional) Set a custom name for the node in the editor. Input msg.payload: The input value to be converted to uppercase (must be a string or convertible to a string). Output msg.payload: The uppercase version of the input string. Example Flow This package includes an example flow that demonstrates how to use the my-example node. To import it:
In the Node-RED editor, go to the menu (top-right) and select Import > Examples. Find @optyne/node-red-contrib-2j4y7k4 in the list and select the example flow. Import and deploy the flow. The example flow includes:
An inject node sending the string "hello". The my-example node converting it to "HELLO". A debug node displaying the result. Here is the JSON for the example flow:
