Debugging the main process
The devtools of browser window can only debug the renderer process scripts.
(I.e. the web pages.) In order to provide a way to debug the scripts of
the main process, Electron has provided the --debug
and --debug-brk
switches.
Command line switches
--debug=[port]
When this switch is used Electron would listen for V8 debugger protocol
messages on port
, the port
is 5858
by default.
--debug-brk=[port]
Like --debug
but pauses the script on the first line.
Use node-inspector for debugging
Note: Electron uses node v0.11.13, which currently doesn't work very well
with node-inspector, and the main process would crash if you inspect the
process
object under node-inspector's console.
1. Start the node-inspector server
$ node-inspector
2. Enable debug mode for Electron
You can either start Electron with a debug flag like:
$ electron --debug=5858 your/app
or, to pause your script on the first line:
$ electron --debug-brk=5858 your/app
3. Load the debugger UI
Open http://127.0.0.1:8080/debug?port=5858 in the Chrome browser.
