Roact
A declarative UI library for Roblox Lua inspired by React
Roact is a declarative view management library for Roblox that is similar to Facebook’s React. You can use Roact to create dynamic graphical user interfaces in Roblox games. Combine with Rodux for optimal syncing with game data when creating GUIs.
Roact has many similarities with React: it exposes an API much like React’s, implements nearly identical semantics, and is made out of elements.
