The issue with pinia computed not updating could be due to a few reasons. Let’s explore them in detail:
1. Reactive Dependencies
Pinia uses Vue 3’s reactivity system, which means that computed properties are updated when their dependencies change. Make sure that the properties used in the computed function are reactive and properly tracked by Vue’s reactivity system. For example:
// Define reactive properties
const state = reactive({
count: 0,
});
// Define computed property
const doubleCount = computed(() => state.count * 2);
// Update the reactive property
state.count++;
console.log(doubleCount.value); // Output: 2
2. Proper Usage of Computed
Ensure that you are using the computed property correctly. Computed properties in Pinia are defined using the `computed` / `defineStore` API. Here’s an example of using computed properties in a Pinia store:
import { defineStore } from 'pinia';
export const useCounterStore = defineStore('counter', {
state: () => ({
count: 0,
}),
getters: {
doubleCount: (state) => state.count * 2,
},
});
// Usage
const counterStore = useCounterStore();
console.log(counterStore.doubleCount); // Output: 0
counterStore.count++;
console.log(counterStore.doubleCount); // Output: 2
3. Reactive Adjustments
If the computed value depends on async operations or external data, ensure that you are handling those dependencies correctly. You might need to use techniques like async/await or promises to handle asynchronous data fetching and update the computed value accordingly.
By addressing these points, you should be able to ensure that your pinia computed properties update correctly.

Note: This example assumes that you already have the necessary CSS styles applied to the `div` element for proper rendering. You may need to adjust the CSS styles according to your requirements.
