Debug node modules in nwjs

问题

We're developing an application based on node webkit (nwjs) that is a mix of node modules and angular code. A lot of business logic has been moved to the node modules and I haven't found a way to debug that code in the running application.

Debugging with devtools doesn't seem to work, and that's a known limitation or bug (Debugging with devtools). I even tried to require node-monkey from one of the scripts, hoping to be able to open some sort of backdoor ;) - didn't work unfortunately.

So is there any other way or trick to (remote) debug the code?

I'm using the Chrome Debugger Extension to debug my node modules in my nwjs app.

Here's the config in launch.json:

{
    "name": "Launch nwjs",
    "type": "chrome",
    "request": "launch",
    "webRoot": "${workspaceRoot}/src", //where you put your .js files
    "runtimeExecutable": "nw"
    "runtimeArgs": [
        "${workspaceRoot}",
        "--chrome-remote-port=9222"
    ],
    "sourceMaps": false,
    "diagnosticLogging": true,
    "port": 9222
},

I had to change some files from VS Code since the editor ignores URL's that starts with chrome-extension:// by default and the Nwjs runs your app under this protocol...

This Issue on GitHub helped me alot.

Have a look at node-inspector

You should be able to start your application with node-debug instead of node and it will open chrome devtools looking inside your app.

You can also use this to debug a remote server.

You can then add breakpoints, watch variables, etc as you would if you were debugging a web application.
