node-red-contrib-diode/diode.js

A simple node to isolate the output of a node or function to that further processing cannot affect the original.

module.exports = function(RED) {
    function diodeNode(config) {
        RED.nodes.createNode(this,config);
        var node = this;
        node.on('input', function(msg) {

            var newMsg = RED.util.cloneMessage(msg);
            node.send(newMsg);
        });
    }
    RED.nodes.registerType("diode",diodeNode);
}
