I was studying the Vue framework today and I put together this little sample app to demonstrate the basics of Vue components and Pinia state management.  Pinia is kinda like Redux for Vue. 

Pinia is a state management system for Vue.js applications. It provides a modern and ergonomic way to manage application state in Vue applications, and it is designed to work seamlessly with the Vue ecosystem. Pinia takes inspiration from concepts in modern state management libraries while focusing on simplicity, performance, and ease of use.

Key features and concepts of Pinia include:

Stores: Pinia introduces the concept of "stores," which are modules that encapsulate a specific piece of application state and its related actions (mutations and actions). Each store represents a distinct area of your application's data and logic.

Reactivity: Pinia leverages Vue's reactivity system, ensuring that changes to store state are automatically reflected in the UI components that depend on that state. This allows you to build reactive and responsive user interfaces.

Composition API: Pinia encourages the use of Vue's Composition API, which provides a more flexible and expressive way to structure component logic. This allows you to create stores using the Composition API's setup function.

Typescript Support: Pinia is designed with TypeScript support in mind. It provides strong typing for stores and their methods, helping you catch type-related errors during development.

Separation of Concerns: Pinia encourages a clear separation of concerns by grouping related state and logic within individual stores. This promotes a modular and maintainable codebase.

Devtools Integration: Pinia integrates with Vue Devtools, making it easier to inspect and debug your store's state and actions.

Plugin System: Pinia supports plugins that can extend its functionality, allowing you to add features or integrations to your stores.

Performance: Pinia aims to be highly efficient and optimized for performance. It utilizes modern JavaScript features and follows best practices to ensure minimal overhead.

Pinia is a standalone state management solution for Vue applications and can be used alongside or as an alternative to other state management libraries such as Vuex. It is particularly well-suited for developers who are familiar with the Composition API and TypeScript and who prefer a more modular approach to managing application state.
