vueuse
A comprehensive collection of essential Vue 3 Composition API utilities for building reactive applications.
What is vueuse?
VueUse is a collection of essential Vue Composition API utilities designed for Vue 3. It provides reusable functions for handling reactivity, browser APIs, state persistence, and more, enabling developers to build complex applications with less boilerplate code. The library is fully tree-shakeable, type-safe, and works seamlessly with server-side rendering.
Vue 3 developers building reactive web applications who want to reduce repetitive code and leverage a comprehensive set of pre-built Composition API utilities. It's especially valuable for teams prioritizing type safety, performance, and modular architecture.
Developers choose VueUse for its extensive, well-documented utility set that integrates perfectly with Vue 3's Composition API. Its tree-shakeable design ensures minimal bundle impact, while TypeScript support and SSR compatibility make it a robust choice for modern Vue development.
Overview
Collection of essential Vue Composition Utilities for Vue 3
Use Cases
Best For
- Adding reactive browser API hooks like useMouse or usePreferredDark to Vue apps
- Managing client-side state persistence with utilities like useLocalStorage
- Reducing boilerplate code for common Vue 3 reactive patterns
- Building SSR-friendly Vue applications with composable utilities
- Prototyping quickly with CDN usage without a bundler
- Integrating advanced features via add-ons like Firebase or Router utilities
Not Ideal For
- Vue 2 applications that are not planning to upgrade to Vue 3, as support was dropped in v12.0.
- Projects using other frameworks like React or Angular, since VueUse is tightly coupled with Vue's Composition API.
- Extremely lightweight Vue apps where only one or two custom hooks are needed, and adding a library adds unnecessary overhead.
- Teams with strict zero-dependency policies who prefer hand-rolled utilities for maximum control and minimal bundle size.
Pros & Cons
Pros
Live demos and comprehensive docs at vueuse.org allow developers to test utilities in real-time, speeding up learning and implementation.
Fully tree-shakeable imports ensure minimal bundle size impact, as evidenced by export size tracking on the official site.
Built with full TypeScript support and TS Docs, providing robust type safety and autocompletion in IDEs.
Designed to be SSR-friendly and usable via CDN without a bundler, making it versatile for prototyping and production.
Cons
Requires Vue 3.5+ from v14.0, which can complicate upgrades for projects stuck on older Vue versions, as noted in the install section.
With over 200 utilities, the extensive API surface can overwhelm developers, leading to decision fatigue or misuse in simpler scenarios.
Optional add-ons for Router or Firebase introduce extra dependencies and setup steps, potentially increasing project complexity and maintenance.
