Learn Pinia in 30 MINUTES! (Vue JS 3)

Step-by-Step Tutorial: Learn Pinia in 30 MINUTES! (Vue JS 3)

1. Install Node.js and Create a Vue Project with Pinia:

• Visit the Vue.js documentation site and click on "install."
• Install Node.js if you haven't already.
• Create a Vue project with Pinia using the command provided in the documentation.
• Choose to add Pinia to your app during project setup.

2. Set Up the Basic Structure of Your App:

• Remove unnecessary code from the Home and About views.
• Create a simple counter app with buttons for increasing and decreasing the count.
• Style the buttons and the counter display.

3. Integrate Pinia State Management:

• Understand the structure of a Pinia store: state, actions, and getters.
• Move the counter data, methods for increasing and decreasing the count, and computed properties into the Pinia store.
• Access the store in your components by importing it and assigning it to a constant.

4. Implement Actions for Modifying State:

• Define actions in the Pinia store for increasing and decreasing the count.
• Access the state properties within an action using this.
• Trigger the actions in your components using the store instance.

5. Utilize Getters for Computed Properties:

• Create getters in the Pinia store to modify or generate data based on state properties.
• Access the state properties in a getter function by passing state as a parameter.
• Use the getters in your components to display computed values.

6. Enable Two-Way Data Binding:

• Add an input field to modify the count value.
• Bind the input field to the state property in the Pinia store using v-model.

7. Share Data Between Components:

• Create a child component for the counter display.
• Import the child component into the parent component.
• Utilize the Pinia store directly in the child component without the need for props or custom events.

8. Further Learning and Resources:

• Explore advanced Pinia features like adding parameters to actions and getters.
• Consider enrolling in a comprehensive Vue JS 3 Composition API course to deepen your understanding of Pinia and state management.

By following these steps, you can quickly grasp the essentials of Pinia for state management in Vue JS 3 applications. Experiment with the concepts and continue exploring to enhance your Vue development skills.
