Pinia Usage

How do I use Pinia to manage state in a Vue application?

Pinia is a state management library for Vue applications. To use Pinia, you need to install it via npm or yarn:

<code class="sh">npm install pinia</code>

or

<code class="sh">yarn add pinia</code>

Next, you need to create a Pinia store. A store is just a JavaScript object that contains the state and methods for manipulating that state. You can create a store using the defineStore function:defineStore function:

<code class="javascript">import { defineStore } from 'pinia'

export const useCounterStore = defineStore('counter', {
  state: () => {
    return {
      count: 0
    }
  },
  actions: {
    increment() {
      this.count++
    },
    decrement() {
      this.count--
    }
  }
})</code>

Once you have created a store, you can access it from any Vue component using the useStore function:

<code class="javascript">import { useStore } from 'pinia'

export default {
  setup() {
    const counterStore = useStore('counter')

    return {
      count: counterStore.count,
      increment: counterStore.increment,
      decrement: counterStore.decrement
    }
  }
}</code>

What are the different ways to access and modify the Pinia store?

You can access the Pinia store using the useStore function. This function takes a string as an argument, which is the name of the store you want to access.

Once you have accessed the store, you can read its state using the state property. You can also modify the store's state by calling the actions defined on the store.

How can I persist the Pinia store to local storage or another data source?

You can persist the Pinia store to local storage or another data source using the persist

<code class="sh">npm install pinia-plugin-persist</code>

<code class="sh">yarn add pinia-plugin-persist</code>

What are the different ways to access and modify the Pinia store?
