How can i put my Codeplayer online safely

Hi Campers!

been a while, I haven’t been coding for a couple of months now, some personal things were more important.
Now I’m starting up again and started updating my portfolio page.
I wanted to add my Codeplayer to my list, but i’ve heard that it can be dangerous if you don’t secure it against the bad guys. Something about them being able to code their way in your computer via the Codeplayer.

Does any of you know how to make it safe? I would love to add it to my site.

thanks for the help!

I thought that’s what is called, since they called it that way in the course I did.:grin:

It’s the same as codepen or something like it. A way to type your code online and see direct result.

Sorry for being so vague, I can’t find anything on it myself.

It was in the course : the complete web developers course 2.0.

He said it in the course while making it, to watch out when putting it online 'cause hackers could potentially do harm trough it, I don’t know how.
It’s just 3 input fields in which you can type HTML5, CSS and JS. And then an iframe in which you see your result.

I don’t want to be the guy to destroy the internet 'cause I didn’t listen.

That’s probably best, thought there might be an easy answer. Just want to make sure it’s safe before putting it on my site. Don’t want to ruïn it.
Thanks for your time :blush:
