What are Pinia getters and how do I use them?

Pinia getters are functions that allow you to compute derived state based on your store's state. They are similar to computed properties in Vue.

Can you give me an example of a Pinia getter?

Sure! Here's a simple example: if you have a store with a state property 'items', a getter could be defined to return the count of items like this: count: (state) => state.items.length.

How do I access a getter in my component?

You can access a getter in your component by using the store instance. For example: const itemCount = store.count;.

Are getters reactive?

Yes, getters are reactive. If the state they depend on changes, the getter will automatically update.
