🍍State Management in Vue.js 3 with Pina and the composition API

Hello tech friend! Today, let's explore state management in Vue.js 3 with Pina.

Pina is a lightweight state management library that provides a simple and intuitive API for managing state in your Vue applications.

Let's dive in and see how Pina can make state management a breeze! 😄 To get started with Pina, we need to set up a new Vue project. If you haven't already, install Vue CLI by running the following command:

npm install -g @vue/cli

Once Vue CLI is installed, create a new project:

vue create my-vue-app

Now that we have our project set up, let's install Pina:

npm install pina

With Pina installed, we can start building our state management logic. Create a new file store.js in the src folder and add the following code:

import { defineStore } from 'pina'
export const useStore = defineStore({
  state: () => ({
    count: 0
  }),
  getters: {
    doubleCount: (state) => state.count * 2
  },
  actions: {
    increment() {
      this.count++
    }
  }
})

In this example, we define a store using the defineStore function from Pina. We specify the initial state with a count property set to 0.

We also define a getter called doubleCount that returns the double of the count value.

Finally, we have an action called increment that increments the count value.

To use the store in our Vue components, we can import the useStore function and use it in the setup function:

import { useStore } from './store'
export default {
  setup() {
    const store = useStore()
    return {
      count: store.count,
      doubleCount: store.doubleCount,
      increment: store.increment
    }
  }
}

In this example, we use the useStore function to create an instance of our store.

We then return the state properties, getter, and action from the setup function to make them accessible in our component.

That's it! With just a few lines of code, we have set up state management with Pina in our Vue application. Feel free to explore more features and capabilities of Pina in the official documentation.

Remember, Pina is a new state management library, so it's always a good idea to refer to the documentation for the latest updates and best practices.

Happy coding! 👩‍💻👨‍💻 Remember, every great developer was once a beginner who never gave up. Keep going! 💼🚀
