🐥 TIL: Resetting the state in a Pinia store

In Option Stores, you can reset the state to its initial value by calling the $reset() method on the store:

const store = useStore()

store.$reset()

Internally, this calls the state() function to create a new state object and replaces the current state with it.

In Setup Stores, you need to create your own $reset() method:

export const useCounterStore = defineStore('counter', () => {
  const count = ref(0)

  function $reset() {
    count.value = 0
  }

  return { count, $reset }
})
