What is the best way to create new nodes and use it in Node-red app. Something like the class concepts in c#. My idea is to create a node to use as a template in different situations, like a form data enter to transfer data to PLC. It should be possible to define the connect communication and use it as a recipe.  
Thanks

You can easily use the javascript classes to define your nodes, for example:

```auto
module.exports = function(RED) {

  class flexdashCtrl {
    // config: name, fd_container
    constructor(config) {
      RED.nodes.createNode(this, config)

...

      this.on("input", msg => {

...

  }
}

```

But I'm not sure that's what you were asking about?

uibuilder makes extensive use of shared classes - specifically single-instance classes. It also uses at least 1 external package for a standardised event-handling class. Though it doesn't go as far as defining the node itself as a class but rather uses a restructured set of functions that makes defining more complex nodes a lot easier and enables easier parsing of the different elements. I've used those principals in a number of nodes now.
