Just checked what's there for libs implementing local state management + server-side sync in vanilla JS. The best options I found were `@tanstack/query-core`[1] and `@signaldb/core`[2]. The former packs no dependencies, with a total size of 89.18 kB if you were to put all the module JS code together, unminified, on a single file. Which could be even smaller with an optimising bundler that tree-shakes and minifies the build.
