Nanostores is a minimalistic and efficient state management library for JavaScript applications. It offers a simple and intuitive API for managing application state with minimal boilerplate code. Nanostores focuses on providing a lightweight solution for state management, making it ideal for small to medium-sized projects where a full-fledged state management library like Redux may be overkill.
Valtio is a minimal and standalone state management library for React applications. It provides a simple API for creating and managing reactive global state without the need for complex setup or boilerplate code. Valtio leverages ES6 Proxies to automatically track state changes and trigger re-renders in components that depend on the state.
Valtio has gained significant popularity in the React community since its release. Nanostores is relatively less popular but still has a decent user base. Both packages are actively used and maintained.
Size
Nanostores is known for its minimalist design and lightweight footprint, making it ideal for small projects or situations where performance is critical. Valtio is also lightweight but includes some additional features and functionality, which might result in a slightly larger bundle size.
Functionality
Nanostores provides a simple and predictable state management solution with a focus on performance. It allows you to create and manage small, independent stores that can be easily composed together. Valtio, on the other hand, offers a similar API but also includes features like deep proxies and automatic batching, which can simplify the development process for complex state management scenarios.
Integration with React
Both Nanostores and Valtio seamlessly integrate with React and can be used as a state management solution in React applications. They provide hooks and utilities that allow you to easily connect and consume state in your components.
Developer Experience
Nanostores follows a minimalist approach and has a very straightforward API, which can lead to a smooth and intuitive developer experience. Valtio, on the other hand, introduces additional concepts like proxies and automatic batching, which might have a steeper learning curve but can also provide more powerful and flexible state management capabilities.
Documentation
Both Nanostores and Valtio have well-documented APIs and provide examples and guides to help developers get started. Nanostores documentation is concise and focuses on the essentials, while Valtio's documentation goes into more detail regarding its advanced features and concepts.
