Valtio State Management
Valtio is a tiny proxy-state library for React, derived from Immer and React.useState.
#What is Valtio?
Valtio is a state management library for React applications that emphasizes simplicity and flexibility. It is designed to make it easy to manage and share state between components, without requiring a lot of boilerplate or configuration. Valtio is lightweight, and has a small API surface area, making it easy to learn and use.
#Valtio Key Features
Most recognizable Valtio features include:
- Minimal API: Valtio has a very small API surface area, making it easy to learn and use.
- Reactivity: Valtio makes use of React’s built-in state and effect hooks to ensure that state changes are automatically propagated to all components that depend on that state.
- Immutability: Valtio uses immutable data structures to ensure that changes to state are always explicit and predictable.
- No global state: Valtio doesn’t rely on a global state store, making it easy to manage state locally within individual components.
- Easy to test: Valtio’s lightweight and simple API makes it easy to write tests for components that use it.
- TypeScript support: Valtio has first-class TypeScript support, making it easy to work with typed state and to catch errors at compile time.
- Valtio can be used in a variety of different contexts, including:
Some of the Valtio use-cases are:
- Small to medium-sized applications: Valtio’s lightweight API and lack of global state make it well-suited to small to medium-sized applications.
- Single-page applications: Valtio can be used to manage state in single-page applications that make heavy use of React.
- Applications with complex state: Valtio’s immutability and reactivity make it a good choice for applications with complex state that needs to be shared between multiple components.
- Applications with real-time updates: Valtio’s reactivity makes it a good choice for applications that need to respond to real-time updates or events.
- TypeScript projects: Valtio has first-class TypeScript support, making it a good choice for projects that use TypeScript.
- Testing: Valtio’s simplicity and lightweight API make it easy to write tests for components that use it.
