React Hooks vs Vue Composables: Complete Comparison for 2026

React Hooks are functions prefixed with use that let React components manage state, side effects, and lifecycle behavior without classes. Vue Composables are functions that leverage Vue's Composition API to encapsulate and reuse reactive logic across components. Both solve the same fundamental problem -- sharing stateful logic -- but they do so with different reactivity models, execution semantics, and ecosystem conventions.

Why This Comparison Matters

Developers moving between React and Vue frequently search for equivalent patterns. Vue's ecosystem has VueUse, a collection of 200+ composables that has become the gold standard for reusable logic. React developers looking for the same breadth of utility hooks now have ReactUse, a library of 100+ hooks directly inspired by VueUse's design philosophy.

Side-by-Side Comparison

Aspect	React Hooks	Vue Composables
Reactivity model	Re-renders the entire component on state change	Fine-grained reactivity via proxied refs
Execution	Runs on every render	Runs once during setup()
State primitive	useState returns value + setter	ref() / reactive() returns a proxy
Side effects	useEffect with dependency array	watchEffect with automatic tracking
Lifecycle	useEffect cleanup pattern	onMounted, onUnmounted, etc.
Rules	Must follow Rules of Hooks (no conditionals)	No ordering constraints
SSR	Requires manual typeof window guards	Built-in onServerPrefetch
Memoization	Explicit (useMemo, useCallback)	Automatic via computed()
Leading utility library	ReactUse (100+ hooks)	VueUse (200+ composables)

How Reactivity Differs Under the Hood

React hooks re-execute on every render. When you call useState, React stores the value in an internal fiber and returns it fresh each time your component function runs. Derived values require useMemo with an explicit dependency array, and skipping a dependency is a common source of bugs.

Vue composables run once inside setup(). Refs and reactive objects are JavaScript proxies that track which effects depend on them. When a ref changes, only the specific effects that read it are re-triggered -- not the entire component. computed() automatically tracks its dependencies with no manual array required.

Code Comparison: useLocalStorage

React with ReactUse:

import { useLocalStorage } from "@reactuses/core";

function Settings() {
  const [theme, setTheme] = useLocalStorage("theme", "light");
  return (
    <button onClick={() => setTheme(theme === "light" ? "dark" : "light")}>
      Current: {theme}
    </button>
  );
}

Vue with VueUse:

<script setup>
import { useLocalStorage } from "@vueuse/core";

const theme = useLocalStorage("theme", "light");

function toggle() {
  theme.value = theme.value === "light" ? "dark" : "light";
}
</script>

<template>
  <button @click="toggle">Current: {{ theme }}</button>
</template>

The API surface is nearly identical. ReactUse returns a [value, setter] tuple that mirrors useState. VueUse returns a reactive ref that you mutate directly.

Code Comparison: useWindowSize

React with ReactUse:

import { useWindowSize } from "@reactuses/core";

function Layout() {
  const { width, height } = useWindowSize();
  return <p>Window: {width} x {height}</p>;
}

Vue with VueUse:

<script setup>
import { useWindowSize } from "@vueuse/core";
const { width, height } = useWindowSize();
</script>

<template>
  <p>Window: {{ width }} x {{ height }}</p>
</template>

Code Comparison: useDark

React with ReactUse:

import { useDarkMode } from "@reactuses/core";

function ThemeToggle() {
  const [isDark, toggle] = useDarkMode({ classNameDark: "dark", classNameLight: "light" });
  return <button onClick={toggle}>{isDark ? "Light" : "Dark"}</button>;
}

Vue with VueUse:

<script setup>
import { useDark, useToggle } from "@vueuse/core";

const isDark = useDark();
const toggle = useToggle(isDark);
</script>

<template>
  <button @click="toggle">{{ isDark ? 'Light' : 'Dark' }}</button>
</template>

Key Differences

Execution model. React hooks run on every render, which means every variable inside a hook is recreated each time the component updates. Vue composables run once, and reactivity is handled through proxies. This is the single largest architectural difference.

Dependency tracking. React requires you to declare dependencies explicitly in arrays (useEffect, useMemo, useCallback). Vue tracks dependencies automatically at runtime. Manual dependency arrays are a frequent source of bugs in React.

SSR approach. Both frameworks support server-side rendering, but the guard patterns differ. React hooks typically check typeof window !== "undefined" before accessing browser APIs. Vue provides lifecycle hooks like onServerPrefetch.

Ecosystem maturity. VueUse has been the dominant utility library in the Vue ecosystem since 2020 and provides over 200 composables. ReactUse is newer but growing quickly, with 100+ hooks that cover the same categories.

ReactUse vs VueUse: The React Equivalent

ReactUse was built explicitly as the React equivalent of VueUse. The two libraries share naming conventions, category organization, and API design principles.

Capability	ReactUse	VueUse
Hook/composable count	100+	200+
TypeScript	First-class	First-class
Tree-shakable	Yes	Yes
SSR-safe	Yes	Yes
Interactive docs	Yes	Yes

For React developers who admire VueUse's breadth and ergonomics, ReactUse is the closest equivalent available today.

FAQ

Are React Hooks the same as Vue Composables?

They serve the same purpose -- encapsulating reusable stateful logic -- but they work differently. React hooks re-execute on every render and require explicit dependency arrays. Vue composables execute once and rely on fine-grained proxy-based reactivity.

Can I use VueUse in React?

No. VueUse depends on Vue's reactivity system. However, ReactUse provides equivalent hooks for React that follow the same naming conventions.

What is the React equivalent of VueUse?

ReactUse (@reactuses/core) is the most direct equivalent. It provides 100+ hooks inspired by VueUse, with TypeScript-first APIs and SSR compatibility. Install it with npm i @reactuses/core.

---

React Hooks and Vue Composables are two answers to the same question: how do you share stateful logic between components? Both approaches work well in production, and both have mature utility libraries -- VueUse for Vue and ReactUse for React.

If you are a React developer looking for the breadth and polish that VueUse brings to Vue, ReactUse is built for you.
