Debugging Node.js
Hiya folks,
I have a node.js project in Netbeans and would like to debug it. When I launch via the debug button, I get the following message on the console, and then a few seconds later, I get the following error.
Console:
"/bin/bash" "-lc" "\"/usr/local/bin/node\" \"--debug-brk=9292\" \"/Users/jryan/JDev/SVN/trunk/Node/CollaborationServer/src/server.js\""
Done.
(node:977) [DEP0062] DeprecationWarning: `node --debug` and `node --debug-brk` are invalid. Please use `node --inspect` or `node --inspect-brk` instead.
Then the following message in a dialog:
Cannot run debugger. Reason:
java.net <http://java.net/>.ConnectException: Connection refused (Connection refused)
It seems like Netbeans needs to update its debug command for current versions of node.js?
Can anyone point me toward how I can update my local copy of Netbeans (I’ve built from from the 10.0 source) to fix this issue, that’d be swell!
-Jess

Bummer. Thanks for looking in to it, though!

Hopefully, some kind person will volunteer to write a v8-inspector debugger module for NB in the future, or add a temporary workaround such as starting node with --inspect and launching Chrome on the DevTools page.

Unfortunately, it seems that --inspect uses a different protocol
(v8-inspector) the --debug (the v8-debugger protocol supported by
Netbeans). Hopefully, some kind person will volunteer to write a
v8-inspector debugger module for NB in the future, or add a temporary
workaround such as starting node with --inspect and launching Chrome on the
DevTools page.
Sorry to be the bearer of bad news :(

I tried! But failed. Thanks for the quick responses.. I tried modifying the hardcoded values in NodeExecutable.java, rebuilt, and, well, things are different, but still it’s a no go. I get the following expected output (which is what you get when running node --inspect src/mystuff.js):
Debugger listening on ws://127.0.0.1:9292/e6fc8a3c-6088-4df0-8a64-dbee7285d9c6
For help, see: https://nodejs.org/en/docs/inspector <https://nodejs.org/en/docs/inspector>
But then the executable stops immediately… so, not sure where that’s going..

Hi Jessica,
I believe it is:
webcommon/javascript.nodejs/src/org/netbeans/modules/javascript/nodejs/exec/NodeExecutable.java
There are a couple of constants near the top of the file: DEBUG_BRK_COMMAND
& DEBUG_COMMAND
If you want to be super-awesome and submit a pull request, the existing
issue in NB's Jira is here:
https://issues.apache.org/jira/browse/NETBEANS-1320

Hi Jess,
And welcome! Yes, someone else reported the same. On GitHub you’ll find the
relevant code in the webcommon folder, or someone else will point you to
the right spot, or I will in a few hours when I get back to my laptop.
