Updating the store

[Jakobud]

Looking at the example

export const preferences = persisted('preferences', {
  theme: 'dark',
  pane: '50%',
  ...
})

How could I go about changing the theme value? What is the syntax?

let pref = get(preferences);
pref.theme = 'light';
preferences.set(preferences); // this doesn't seem right

Really just kinda not clear from your documentation examples. You just say preferences.set(...) // set value but what is that? What value am I setting? Where do I put in the key for the object I want to change?

Svelte's writable stores come with an update() function.

You can mutate state like this:

preferences.update(state => {
   return {...state, theme: 'light' } 
})

I think this should be added to the readme, it took me a while to figure it out

Thanks I didn't see the discussions

No worries! I set them up just now (forgot to turn them on before)
