VueUse - The library that makes Vue 3 worth the upgrade

VueUse - The library that makes Vue 3 worth the upgrade

Composition API promotes a much better paradigm of sharing code between components. Explicit dependencies and namespacing by design enable us to share code even between different projects. This is the main idea behind VueUse.

VueUse is a collection of 200+ essential utility functions for interacting with various APIs like browser, state, network, animation, time and more.

A small sample of these utilities enables you to:

• use the clipboard API (demo below)
• reactive time ago (demo below)
• watch debounced or throttled
• create virtual lists with ease
• create fancy favicons or page titles
• track window size and focus
• track the visibility of an element within the viewport
• create a zone where files can be dropped (demo below)
• make elements draggable
• create reactive LocalStorage/SessionStorage

and so many more!

Extensible with add-ons

The core package aims to be lightweight and dependence free. Integration with popular packages is supported using add-ons. This ensures a consistent API style.

Some existing add-ons currently are:

• Electron
• Firebase
• Motion
• RxJS
• Sound

Conclusion

We only touched the surface, but hopefully, you got the idea of how awesome this library is. There are hundreds of utilities to explore (currently 274!), and the number is constantly rising. Of course, you can contribute your own If you find something’s missing.

Libraries like VueUse are leading the way to make Vue awesome again. They promote code reusability and improve the overall developer experience.

Dive into the awesome documentation, spread the word and maybe give the author a credit (or buy him a coffee ☕️).
