Debounced setState a bad idea? #406

Closed jaunt closed 3 years ago

My app quite heavily writes to vuex at times, and since setState is calling json.stringify and writing to localstorage, is there any harm debouncing the final write until things settle?

Here's an example of what I mean:


      setState: (key, state, storage) => {
        // debounce storing state
        if (persistTimer != null) {
          clearTimeout(persistTimer);
        }
        persistTimer = setTimeout(() => {
          storage.setItem(key, JSON.stringify(state));
          persistTimer = null;
        }, 100);
      },

If writing to LocalStorage becomes a performance bottleneck, I would suggest revisiting your application architecture. I would definitely not recommend doing async writes to prevent state mismatch issues.
