I was continueing my exploration of React server components when I stumbled upon on this article about progressive JSON. Dan Abramov describes a technique for streaming JSON from a server to a client in chunks, allowing the client to start rendering parts of the data before the entire payload has been received. This can significantly improve perceived performance, especially for large datasets. So, I started wondering how much of an effort it would be to implement something like that. It turned out a fun exercise, and I ended up with a small (200loc) library called Streamson. So, this post is about how I built it.

I'm working on a year old application written in node. There is twitter streaming API implemented and it worked before a couple of months. These days we moved the site on another server and I found that it is not working anymore.
