npm i valtio makes proxy-state simple. valtio turns the object you pass it into a self-aware proxy. you can make changes to it in the same way you would to a normal js-object. create a local snapshot that catches changes. rule of thumb: read from snapshots, mutate the source. the component will only re-render when the parts of the state you access have changed, it is render-optimized. if you are new to this, it's highly recommended to use eslint-plugin-valtio. you can access state outside of your components and subscribe to changes. you can also subscribe to a portion of state. to subscribe to a primitive value of state, consider subscribekey in utils. there is another util watch which might be convenient in some cases. valtio supports react-suspense and will throw promises that you access within a components render function. this eliminates all the async back-and-forth, you can access your data directly while the parent is responsible for fallback state and error handling. this may be useful if you have large, nested objects with accessors that you don't want to proxy. ref allows you to keep these objects inside the state model. see #61 and #178 for more information. you can
