No, no it makes exactly zero sense to have a "reconciliation engine" or React in a TUI. There's nothing to reconcile. You can just output a stream of characters as fast as they appear.

That’s not a TUI, that’s a CLI.

Any stateful UI needs a state management backend and a rendering frontend, React isn’t a bad choice for the former.

React is not, and has never been a "state management backend".

There are about a million other ways of doing state management than retrofitting it into both React and TUI.

Parent comment talks about using React for reconsilliation which is React-speak for "we take a diff between current state of UI and new state of UI, and apply that diff". Which is entirely unnecessary not just for TUIs, but for the vast majority of GUIs in general, especially for non-DOM-based ones.

As an example, in Claude Code this insanity leads to them spending 16ms "creating a scene" and rendering a couple of hundred of characters on screen: https://x.com/trq212/status/2014051501786931427

That post doesn't say that it takes 16ms to create a scene and have the terminal rasterize and try and present it. That's just the budget they have. It is the upper bound they have to work with.

For example Claude Code could emit a strange symbol and if the terminal has to go and load a font from disk to be able to rasterize something that can eat into the budget and prevent the terminal from having a smooth frame rate by causing a frame drop.

Never said what CC is doing is right. Using React for knowing what to render is good enough for state management for me, that they can’t or won’t figure out how to emit less escape sequences than they need to (which is a solved problem for 40 or 50 years now in windowing UIs) is a different thing.

For the record I can’t stand CC flickering and general slowness and ditched Claude subscription entirely.
