Extending preview command
If you specify a new run() function the command will run only the new one, otherwise, it wouldn't be possible to fully change a command (here more about extending commands)

I am trying to extend the preview command. I expected the code below to run the normal preview command along with console output, but only console statement runs. How can I preserve the original preview code?
editor.Commands.extend('preview', {
run() {
console.log("foo");
}
});
The below works for me until someone can enlighten where my thought process went wrong.
editor.Commands.add('preview-ext', {
run(e) {
e.runCommand('preview');
console.log("foo");
}
});

Hello Artf, oddly enough, i need the same thing he does.
So, the best way to do is doing the same way he does? Running the original preview command inside the extended preview?
Well...
Other thing i'm doing is extending the preview by running the command on event.:
editor.on("run:preview",()=>{console.log("run-preview")});
editor.on("stop:preview",()=>{console.log("stop-preview")});
Thanks for reporting this, @kerryj89. Great question about Extending preview command. The recommended approach with GrapesJS is to use the event-driven API.
