A few years ago we released a couple of Node.js prototype applications that allowed you to add WHIP and WHEP support to Janus. We recently turned those applications to Node.js libraries that you can use in your own application, and since those libraries use Janode too, they’ll be even easier to integrate if you use it already. If you want to learn more, I wrote a detailed blog post that also presents a few practical examples.
Should you need help with those libraries, we created a brand new category you can refer to.
