airbnb/react-sketchapp

react-sketchapp is an open source library from Airbnb that lets you write React components and then render them as documents inside Sketch, the popular design app on macOS. The README describes it as tailor-made for design systems, the collection of buttons, type styles, color palettes, and other building blocks that a large team shares across many products. The reason it exists, according to the README, is that managing design system assets directly in Sketch is complex, error prone, and time consuming. Sketch is scriptable, but its API changes often. By using React as a wrapper, the project lets JavaScript developers describe Sketch documents in a way that already feels familiar to them, instead of writing low-level Sketch plugin code. A short code sample in the README shows the idea: you import components like Artboard and Text from react-sketchapp, write a normal-looking React component, and then call render to draw it onto the current Sketch page. The README lists four things you can do with it: manage design systems the way Airbnb does internally, build designs as real reusable components, design with real data fetched from APIs instead of placeholder text, and build new custom design tools on top of Sketch as a drawing canvas. To try it you install Sketch version 50 or newer, clone the repo, go into the basic-setup example, run npm install, then npm run render. Documentation, more examples, and an API reference are linked from the README.
