How to render to a stream (allow web users to stream rendering video)

I am using Adobe After Effects CC and ExtendScript to create dynamic videos and then let the user watch those videos.

I looked at this tutorial (don't need to read this tutorial to understand the context of this discussion): https://www.themarketingtechnologist.co/creating-dynamic-videos-using-javascript-and-after -effects-the-basics/

Basically, the tutorial goes through how to create dynamic videos with After Effects and render them.

Right now, I can use extend script to create dynamic videos to the user's preferences and render them.

However, when I render the video, I have to wait till rendering is completely done before the user can start watching the video at 0:00 (via a HTML5 player).

Is there a way to allow the user to stream the video as soon as the first frame or block of frames is rendered?

In other words, is there a way to allow the user to stream a video before that video has fully rendered.

Should I directly render the video on After Effects or Adobe Media Encoder?

Thank you!
