insomnia-plugin-xdebug

Little Insomnia plugin that easily allows you to enable Xdebug debugging by adding an XDEBUG_SESSION cookie to the request.

To enable, simply check the Xdebug checkbox...
Uncheck to disable.

Sreenshot Xdebug plugin

The XDEBUG_SESSION's value has been set to Insomnia... This can easily be edited in ./src/plugin.js.
Most modern IDEs will accept any incoming connection on port 9000 (or another if configured otherwise) regardless of the value of the XDEBUG_SESSION.
