DEV Question. Local Server , how to debug a custom node w/o restarting server.

[Maelstrom2014]

Hello, Everyone!
I'm new here. If i write in wrong tree, please point me were to ask dev questions, thanx.

So, I'm make a custom node and making constant changes to script.

Is it any way to re-run just edited (.py) custom script, W/O restarting server?

It take too much time even locally.

I tried to delete pychon cache, but no luck.
Refreshing a page, not helps.

I would also like to know the answer from some of the senior developers :)

For me restarting the server is pretty fast, because after the first run all python files stay cached in the RAM by the OS, so just a few seconds, most of the time it is like 5-6 seconds to restart, but it would be nice to have a faster way of doing it anyway.

Btw, I use linux ubuntu, I don't know if other OS works in that same way regarding file caching, for me even the safetensor is cached by the OS and load fast after the restart.

Sorry to necro an old thread, but in case anyone else comes across this thread, here is a decent guide on getting debugging running. Method 1 with a portable comfyui works well and restarts quickly, especially if you add the restart button to the menu in the second link.

Debugging python works well, I haven't figured out JavaScript debugging however.
