Why is HMR not preserving my local component state?
HMR state preservation comes with a number of gotchas! It has been disabled by default in both svelte-hmr
and @sveltejs/vite-plugin-svelte
due to its often surprising behavior. You can read the details here.
If you have state that's important to retain within a component, consider creating an external store which would not be replaced by HMR.
// store.ts
// An extremely simple external store
import { writable } from 'svelte/store';
export default writable(0);
