The DevTools in an Electron browser window can only debug JavaScript that’s executed in that window (i.e. the web pages). To debug JavaScript that’s executed in the main process you will need to use an external debugger and launch Electron with the --inspect
or --inspect-brk
switch.
Use one of the following command line switches to enable debugging of the main process:
--inspect=[port]
Electron will listen for V8 inspector protocol messages on the specified port
, an external debugger will need to connect on this port. The default port
is 5858
.
electron --inspect=5858 your/app
--inspect-brk=[port]
Like --inspector
but pauses execution on the first line of JavaScript.
You will need to use a debugger that supports the V8 inspector protocol.
chrome://inspect
and selecting to inspect the launched Electron app present there.
