Title: Node-RED Contrib Simple Array Key and Value

Description: Simple Array Key and Value is a custom Node-RED node that allows you to dynamically add key-value pairs to an existing array in msg.payload. This node is ideal for building data structures flexibly during flow processing.

Features:

• Dynamically Add Items: Add key-value pairs to the array in msg.payload configured directly via the node’s interface.
• Field Validation: Ensures that all required fields (key and value) are correctly filled before processing.
• Array Management: Initializes arrays in msg.payload if they do not exist, preventing errors during the flow.

Installation: To install this node, you can use NPM directly in your Node-RED directory: Command: npm install node-red-contrib-simple-array-key-value Or, to install globally: Command: npm install -g node-red-contrib-simple-array-key-value

How to Use:

1. Drag the "Simple Array Key and Value" node into your Node-RED flow.
2. Configure the key-value pairs you want to add to the array in msg.payload.
3. Connect the node to your flows to start dynamically adding data.

Inputs:

• msg.payload: An array where the configured key-value pairs will be added. If it's not an array, the node will initialize it as an empty array.

Outputs:

• msg.payload: Returns the array with the key-value pairs added as configured.
