Is there a way to integrate our app + code in wordpress?

I saw some syntax highlighters working nicely.

But I'd like to know about the app itself. Indeed, we can include applets in posts, but imagine to include one applet per post on the homepage showing the latest 10 posts, the website visitor cpu would burnt :-/

There is the option to not show all the post but an excerpt only, but it is not really attractive except if you put a picture snapshot of the app.

So I just wanted to know what you were using. I probably missed THE way you all use here.

Any leads would be appreciated.

best,
