What are the best practices for using Pinia and Vuex in my Vue.js application?

When using Pinia and Vuex, it's important to keep your state management organized. Here are some best practices:

1. Modularize your stores: Break down your stores into modules for better maintainability.
2. Use actions for asynchronous operations: Keep your state mutations synchronous and handle async logic in actions.
3. Leverage getters: Use getters to compute derived state and keep your components clean.

Can you explain why modularizing stores is important?

Modularizing stores helps in managing large applications by separating concerns. Each module can handle its own state, actions, and mutations, making it easier to maintain and scale your application.

What are some common pitfalls to avoid when using these state management libraries?

Common pitfalls include:

1. Overusing global state: Only store what is necessary in the global state to avoid complexity.
2. Not using actions for async calls: This can lead to unpredictable state changes.
3. Neglecting to use getters: This can result in duplicated logic across components.

How do I decide whether to use Pinia or Vuex?

If you're starting a new project, Pinia is recommended for its simplicity and better TypeScript support. Vuex is still a solid choice for existing projects or if you need more advanced features.
