Phelia transforms React components into Slack messages by use of a custom React reconciler. Components (with their internal state and props) are serialized into a custom storage. When a user interacts with a posted message Phelia retrieves the component, re-hydrates it’s state and props, and performs any actions which may result in a new state.

It’s crazy interesting to me how many of these “Use React for X” projects keep popping up. People are making CLIs with React, games with React, desktop apps with React. What else?
