Eli5 how to use console to debug a custom node

[io_io]

Describe the issue/error/question

Disclaimer - I am not a dev but have some python experience, mostly with pycharm ide and i believe it impacts my ability to understand ts\js debugging process in vscode. Also this is first time i attempt a js project.

I am making a custom node to wrap an existing js api wrapper and it works out well since i build it over existing codebase and I can debug my queries right in the node, more or less.

However i got stuck trying to implement a method to get list of folders and feed them to resourceLocator.
I need a tool to see what exactly happens when resourceLocator cqlls my method and what happens inside it.

I did my best to parse this forum and find something i can adopt, Tried to implement this env but no luck there.

Debugging custom modules/nodes/credentials

Sharing My Findings Here is how I set up a VSCode environment for developing and debugging n8n and a custom nodes package. Many of it is based on the post https://community.n8n.io/t/how-to-run-n8n-in-debug-mode-with-vscode/, but with a lot of things that I had figured out, partially for not being a skilled Typescript programmer. There are 2 different parts: the n8n itself, and a custom module that I will call n8n-nodes-custom (from here). So, I created a folder to keep everything in, and ins…

It seems like I miss some basic node knowlege and\or project evolves faster then manuals.

tldr>
I am trying to debug method I call with resourceLocator and I do not understand how to do it.

macos, VSCode,
n8n workflow based on GitHub - n8n-io/n8n-nodes-starter: Example starter module for custom n8n nodes.

Information on your n8n setup

Hey @io_io,

Welcome to the community

I don’t think there is currently a solid way to debug a custom node outside of just adding a bunch of console.log() lines to your project then checking the n8n output.

What I do though when I make mine is I will make a new local branch of the n8n project, Make my node in packages/nodes-base then I can just run n8n from source and test my node then once I am happy with everything it is a quick copy / paste into a copy of the n8n node template, give it one more test like that and all is good.
