Hi, I'm writing a custom node plugin and I would like to display in the HTML form page some data that's available in the node.js side of the script. I can't really understand how to do that and I can't find any documentation, could someone point me in the right direction please?
To give some context, I'm generating a setup code and I need to display it on the Node-RED ui to allow the user to use it.
The core serial node has a simple example. For more complex examples, you can wade through the uibuilder code. All of the web processing in uibuilder starts from the UibWeb class in libs/web.js.
Should work I think. if you manually set the url in the browser to http://127.0.0.1:1880/my-path/abc, does that work?
You probably want to use RED.httpAdmin.get rather than use, just so it is clear you only ever want to use a GET on that endpoint.
I always use query arguments on GET REST API's. If I need something more complex, I'll use POST with a body containing JSON. You should always use POST if needing to send anything sensitive (and use HTTPS of course). I have a helper function that puts all parameters no matter what form they come in into a standard object.
