Vue 3 for React Developers: Side-by-Side Comparison with Demos

Master Vue 3 by leveraging your React knowledge. Compare code patterns side-by-side with practical examples you can run and modify.

Why React Developers Choose Vue 3

If you know React and want to learn Vue 3, you're in luck. These frameworks share many conceptual roots--both are component-based, use virtual DOM, and emphasize reactive UI updates. But their approaches differ in important ways that affect how you write code.

This guide provides side-by-side code comparisons so you can see exactly how the same functionality looks in each framework, with practical demos you can run and modify.

The Conceptual Bridge

Both Vue and React embrace the component-based architecture that has dominated modern frontend development. They share fundamental concepts:

  • Component-based architecture for building reusable UI pieces
  • Virtual DOM for efficient rendering updates
  • Reactive data binding for automatic UI synchronization
  • Props for passing data between components
  • Lifecycle management for side effects and cleanup

Understanding these shared foundations makes the transition smoother, even as the implementation details differ.

What Makes Vue 3 Different

Vue 3 introduces the Composition API as a flexible alternative to the Options API, bringing it closer to React's hook-based patterns while maintaining Vue's distinctive reactivity system. Our web development team regularly works with both frameworks to deliver optimal solutions for client projects.

Component Structure: Side-by-Side Comparison

The most visible difference between Vue 3 and React is how components define their UI. React uses JSX (JavaScript), while Vue 3 uses HTML-like templates with special directives.

Template vs JSX

// React functional component
function Counter({ initialCount }) {
 const [count, setCount] = React.useState(initialCount);

 return (
 <div className="counter">
 <h2>Count: {count}</h2>
 <button onClick={() => setCount(count + 1)}>
 Increment
 </button>
 </div>
 );
}
<!-- Vue 3 component with Composition API -->
<script setup>
import { ref } from 'vue';

const props = defineProps({
 initialCount: {
 type: Number,
 default: 0
 }
});

const count = ref(props.initialCount);

function increment() {
 count.value++;
}
</script>

<template>
 <div class="counter">
 <h2>Count: {{ count }}</h2>
 <button @click="increment">Increment</button>
 </div>
</template>

State Management: ref vs useState

State management in Vue 3 and React follows different mental models, though they achieve similar outcomes.

React: Direct State Values

In React, useState returns the current state value and a setter function. State updates trigger re-renders automatically.

// React - direct value access
import { useState } from 'react';

function UserProfile() {
 const [user, setUser] = useState({ name: '', email: '' });
 const [isLoading, setIsLoading] = useState(false);

 async function updateUser(name) {
 setIsLoading(true);
 // State updates are async and batched
 const updated = await fetchUserUpdate(name);
 setUser(updated);
 setIsLoading(false);
 }

 return (
 <div>
 <p>{user.name}</p>
 {isLoading && <span>Loading...</span>}
 </div>
 );
}

Vue 3: Reactive References

Vue 3 uses ref() to create reactive values. Access the underlying value with .value in script, but not in templates.

<script setup>
import { ref } from 'vue';

const user = ref({ name: '', email: '' });
const isLoading = ref(false);

async function updateUser(name) {
 isLoading.value = true;
 // Await works naturally with refs
 const updated = await fetchUserUpdate(name);
 user.value = updated;
 isLoading.value = false;
}
</script>

<template>
 <div>
 <p>{{ user.name }}</p>
 <span v-if="isLoading">Loading...</span>
 </div>
</template>

Understanding the .value Pattern

The .value requirement in Vue 3 serves an important purpose: it makes the distinction between reactive and non-reactive code explicit. In template expressions, Vue automatically unwraps refs, but in JavaScript code, you must access the value property.

This design prevents a common React pitfall where developers accidentally modify state without using the setter function. In Vue, the .value makes mutation intentional.

The Composition API: Vue's Answer to Hooks

Vue 3's Composition API and React Hooks represent convergent evolution in how these frameworks handle logic reuse and stateful components.

React Hooks Pattern

React Hooks allow you to extract and reuse stateful logic across components.

import { useState, useEffect, useCallback } from 'react';

function useWindowSize() {
 const [size, setSize] = useState({ width: 0, height: 0 });

 useEffect(() => {
 function handleResize() {
 setSize({
 width: window.innerWidth,
 height: window.innerHeight
 });
 }

 window.addEventListener('resize', handleResize);
 handleResize();

 return () => window.removeEventListener('resize', handleResize);
 }, []);

 return size;
}

function useLocalStorage(key, initialValue) {
 const [value, setValue] = useState(() => {
 const stored = localStorage.getItem(key);
 return stored ? JSON.parse(stored) : initialValue;
 });

 useEffect(() => {
 localStorage.setItem(key, JSON.stringify(value));
 }, [key, value]);

 return [value, setValue];
}

Vue 3 Composables Pattern

Vue 3 uses composables--functions that leverage the Composition API--to achieve similar reuse.

// composables/useWindowSize.js
import { ref, onMounted, onUnmounted } from 'vue';

export function useWindowSize() {
 const size = ref({ width: 0, height: 0 });

 function handleResize() {
 size.value.width = window.innerWidth;
 size.value.height = window.innerHeight;
 }

 onMounted(() => {
 window.addEventListener('resize', handleResize);
 handleResize();
 });

 onUnmounted(() => {
 window.removeEventListener('resize', handleResize);
 });

 return size;
}

// composables/useLocalStorage.js
import { ref, watch } from 'vue';

export function useLocalStorage(key, initialValue) {
 const stored = localStorage.getItem(key);
 const value = ref(stored ? JSON.parse(stored) : initialValue);

 watch(value, (newValue) => {
 localStorage.setItem(key, JSON.stringify(newValue));
 });

 return value;
}

Key Architectural Differences

Execution Model:

  • React Hooks: Called on every render, must follow Rules of Hooks
  • Vue Composables: Can use lifecycle functions, more flexible composition

Dependencies:

  • React: useEffect/useMemo deps arrays are mandatory
  • Vue: watch/watchEffect automatically track dependencies

Cleanup:

  • React: Return cleanup function from useEffect
  • Vue: Use onUnmounted lifecycle hook or watch cleanup
Hooks vs Composables

Execution

React Hooks run on every render; composables use lifecycle functions

Dependencies

React requires explicit deps arrays; Vue auto-tracks dependencies

Cleanup

React returns cleanup from useEffect; Vue uses onUnmounted hook

Flexibility

Vue composables offer more flexible composition patterns

Reactivity Systems: How Updates Flow

The reactivity model affects how you think about performance and code organization.

Vue 3's Reactivity System

Vue 3 uses a proxy-based reactivity system. When you wrap data in ref() or reactive(), Vue creates reactive proxies that automatically track dependencies.

import { ref, reactive, watch, computed } from 'vue';

const count = ref(0);
const user = reactive({ name: 'John' });

// Computed automatically tracks dependencies
const doubleCount = computed(() => count.value * 2);

// Watch reacts to specific changes
watch(count, (newVal, oldVal) => {
 console.log(`Count changed from ${oldVal} to ${newVal}`);
});

// Vue's reactivity graph handles updates automatically
count.value++; // Triggers all dependent reactions

React's Rendering Model

React uses explicit state updates. When state changes, you must trigger a re-render, and React determines what changed through its reconciliation algorithm.

import { useState, useEffect, useMemo, useCallback } from 'react';

function Counter() {
 const [count, setCount] = useState(0);
 const [user, setUser] = useState({ name: 'John' });

 // Manual dependency tracking through useMemo
 const doubleCount = useMemo(() => count * 2, [count]);

 // Explicit effect with dependency array
 useEffect(() => {
 console.log(`Count changed`);
 }, [count]);

 // Manual optimization through useCallback
 const increment = useCallback(() => {
 setCount(c => c + 1);
 }, []);

 return <button onClick={increment}>{doubleCount}</button>;
}

Performance Implications

The reactivity model affects how you think about performance:

  • Vue: Fine-grained reactivity means only the exact parts of the DOM that need updating change. However, creating too many reactive objects can add overhead.
  • React: React's scheduler and reconciliation determine updates. Proper use of useMemo and useCallback prevents unnecessary re-renders.

For large applications, Vue's reactivity system can reduce boilerplate around optimization, while React gives you more control over exactly when things re-render.

Computed Values and Derived State

Vue 3 Computed Properties

Vue 3's computed() creates lazily-evaluated, cached values that automatically update when their dependencies change.

<script setup>
import { ref, computed } from 'vue';

const items = ref([1, 2, 3, 4, 5]);
const filter = ref('');

const filteredItems = computed(() => {
 return items.value.filter(item =>
 item.toString().includes(filter.value)
 );
});

const total = computed(() =>
 filteredItems.value.reduce((sum, item) => sum + item, 0)
);

// Computed is read-only by default
// To create a writable computed, provide getter and setter:
const doubleTotal = computed({
 get() {
 return total.value * 2;
 },
 set(newValue) {
 // Handle the update
 console.log('Setting doubleTotal to:', newValue);
 }
});
</script>

React's useMemo and useCallback

React requires explicit memoization to achieve similar caching behavior.

import { useState, useMemo, useCallback } from 'react';

function ItemList() {
 const [items, setItems] = useState([1, 2, 3, 4, 5]);
 const [filter, setFilter] = useState('');

 const filteredItems = useMemo(() =>
 items.filter(item => item.toString().includes(filter)),
 [items, filter]
 );

 const total = useMemo(() =>
 filteredItems.reduce((sum, item) => sum + item, 0),
 [filteredItems]
 );

 // Callback memoization prevents child re-renders
 const addItem = useCallback(() => {
 setItems(prev => [...prev, prev.length + 1]);
 }, []);

 return (
 <>
 <input
 value={filter}
 onChange={e => setFilter(e.target.value)}
 />
 <List items={filteredItems} total={total} />
 <button onClick={addItem}>Add Item</button>
 </>
 );
}

Key Differences

  • Vue's computed values are cached and only recalculate when dependencies change
  • React's useMemo requires explicit dependency arrays
  • Vue computed properties are read-only by default (can be made writable)
  • React's useCallback memoizes functions to prevent unnecessary child re-renders

Conditional Rendering: Directives vs Expressions

Vue 3 Conditional Directives

Vue provides purpose-built directives for conditional rendering:

<template>
 <!-- v-if - removes from DOM entirely -->
 <div v-if="isLoggedIn">
 Welcome back, {{ user.name }}
 </div>

 <!-- v-else-if and v-else chains -->
 <div v-else-if="isRegistering">
 Create your account
 </div>
 <div v-else>
 <button @click="login">Log In</button>
 </div>

 <!-- v-show - toggles CSS display (always in DOM) -->
 <div v-show="showNotification">
 This notification uses v-show
 </div>

 <!-- v-if with template for multiple elements -->
 <template v-if="showDetails">
 <span>Detail 1</span>
 <span>Detail 2</span>
 <span>Detail 3</span>
 </template>
</template>

React Conditional Expressions

React uses JavaScript expressions for conditional rendering:

function UserComponent({ isLoggedIn, isRegistering, user, showNotification, showDetails }) {
 return (
 <>
 {/* v-if equivalent */}
 {isLoggedIn && (
 <div>Welcome back, {user.name}</div>
 )}

 {/* v-else-if/v-else equivalent */}
 {isRegistering ? (
 <div>Create your account</div>
 ) : (
 <button onClick={login}>Log In</button>
 )}

 {/* v-show equivalent - use CSS */}
 <div style={{ display: showNotification ? 'block' : 'none' }}>
 This notification uses CSS display
 </div>

 {/* Fragment for multiple elements */}
 {showDetails && (
 <>
 <span>Detail 1</span>
 <span>Detail 2</span>
 <span>Detail 3</span>
 </>
 )}
 </>
 );
}

Choosing Between Approaches

  • Vue v-if vs React &&: Both conditionally render, but React's && can't render 0 (falsy). Vue handles this better.
  • v-show vs CSS display: Use v-show for frequently toggled elements to avoid DOM manipulation costs.
  • Template syntax: Vue's directives are more declarative for template readers; React's expressions are more flexible.

List Rendering: v-for vs map

Vue 3 v-for Directive

<template>
 <!-- Basic v-for with index -->
 <ul>
 <li v-for="(item, index) in items" :key="item.id">
 {{ index + 1 }}. {{ item.name }}
 </li>
 </ul>

 <!-- v-for with object -->
 <div v-for="(value, key, index) in user" :key="key">
 {{ index }}: {{ key }} = {{ value }}
 </div>

 <!-- v-for on template for multiple elements -->
 <template v-for="item in items" :key="item.id">
 <div class="item">{{ item.name }}</div>
 <hr class="divider" />
 </template>
</template>

React map Method

function ListComponent({ items, user }) {
 return (
 <>
 {/* Basic map */}
 <ul>
 {items.map((item, index) => (
 <li key={item.id}>
 {index + 1}. {item.name}
 </li>
 ))}
 </ul>

 {/* Object iteration */}
 {Object.entries(user).map(([key, value], index) => (
 <div key={key}>
 {index}: {key} = {value}
 </div>
 ))}

 {/* Array from for range */}
 {[...Array(5)].map((_, n) => (
 <span key={n}>{n + 1} </span>
 ))}
 </>
 );
}

Key Differences

  • Vue's v-for includes index, key, and value parameters
  • React's map is a standard JavaScript array method
  • Both require unique :key or key prop for proper diffing
  • Vue's template v-for handles multiple elements elegantly

Lifecycle and Side Effects

Vue 3 Lifecycle Hooks

<script setup>
import { onMounted, onUpdated, onUnmounted, onBeforeMount } from 'vue';

onBeforeMount(() => {
 // Before component is mounted to DOM
 console.log('Component about to mount');
});

onMounted(() => {
 // After component is mounted - safe for DOM operations
 console.log('Component mounted');
 const element = document.getElementById('my-element');
});

onUpdated(() => {
 // After component updates (re-renders)
 console.log('Component updated');
});

onUnmounted(() => {
 // Cleanup before component is destroyed
 console.log('Component unmounted');
});

// Composition API-specific hooks
import { onRenderTracked, onRenderTriggered } from 'vue';

// Debug reactivity tracking (development only)
onRenderTracked(({ target, key, type }) => {
 console.log('tracked:', target, key, type);
});

onRenderTriggered(({ target, key, type }) => {
 console.log('triggered:', target, key, type);
});
</script>

React useEffect Hook

import { useEffect, useRef } from 'react';

function Component() {
 const ref = useRef(null);

 useEffect(() => {
 // Runs after mount and after every render by default
 console.log('Effect runs');

 // Optional cleanup function (runs before unmount and before re-run)
 return () => {
 console.log('Cleanup before next effect or unmount');
 };
 }); // Empty deps = runs once on mount, cleanup on unmount

 useEffect(() => {
 // Runs when count changes
 console.log(`Count is: ${count}`);
 }, [count]); // Dependency array controls when effect runs

 useEffect(() => {
 // Safe DOM access after render
 if (ref.current) {
 ref.current.focus();
 }
 }, []);

 return <div ref={ref}>Content</div>;
}

Form Handling and Two-Way Binding

Vue 3 v-model

Vue's v-model creates two-way binding with form inputs:

<template>
 <!-- Text input -->
 <input v-model="message" placeholder="Type something" />
 <p>You typed: {{ message }}</p>

 <!-- Checkbox -->
 <input type="checkbox" v-model="checked" id="checkbox" />
 <label for="checkbox">{{ checked ? 'Checked' : 'Unchecked' }}</label>

 <!-- Multiple checkboxes bound to array -->
 <div>
 <input type="checkbox" value="A" v-model="selected" id="a" />
 <label for="a">A</label>
 <input type="checkbox" value="B" v-model="selected" id="b" />
 <label for="b">B</label>
 <input type="checkbox" value="C" v-model="selected" id="c" />
 <label for="c">C</label>
 </div>
 <p>Selected: {{ selected }}</p>

 <!-- Select -->
 <select v-model="selectedOption">
 <option value="">Choose an option</option>
 <option value="a">Option A</option>
 <option value="b">Option B</option>
 </select>

 <!-- v-model modifiers -->
 <input v-model.lazy="lazyInput" /> <!-- Updates on change, not input -->
 <input v-model.number="numberInput" /> <!-- Automatically parses numbers -->
 <input v-model.trim="trimmedInput" /> <!-- Trims whitespace -->
</template>

<script setup>
import { ref } from 'vue';

const message = ref('');
const checked = ref(false);
const selected = ref([]);
const selectedOption = ref('');
const lazyInput = ref('');
const numberInput = ref('');
const trimmedInput = ref('');
</script>

React Controlled Components

React requires explicitly controlled components:

import { useState } from 'react';

function FormComponent() {
 const [message, setMessage] = useState('');
 const [checked, setChecked] = useState(false);
 const [selected, setSelected] = useState([]);
 const [selectedOption, setSelectedOption] = useState('');
 const [lazyInput, setLazyInput] = useState('');
 const [numberInput, setNumberInput] = useState('');
 const [trimmedInput, setTrimmedInput] = useState('');

 const handleCheckbox = (e) => {
 setChecked(e.target.checked);
 };

 const handleMultiSelect = (value) => {
 setSelected(prev =>
 prev.includes(value)
 ? prev.filter(v => v !== value)
 : [...prev, value]
 );
 };

 const handleSubmit = (e) => {
 e.preventDefault();
 console.log({ message, checked, selected, selectedOption });
 };

 return (
 <form onSubmit={handleSubmit}>
 <input
 value={message}
 onChange={e => setMessage(e.target.value)}
 placeholder="Type something"
 />
 <p>You typed: {message}</p>

 <input
 type="checkbox"
 checked={checked}
 onChange={handleCheckbox}
 id="checkbox"
 />
 <label htmlFor="checkbox">
 {checked ? 'Checked' : 'Unchecked'}
 </label>

 <div>
 {['A', 'B', 'C'].map(value => (
 <label key={value}>
 <input
 type="checkbox"
 checked={selected.includes(value)}
 onChange={() => handleMultiSelect(value)}
 />
 {value}
 </label>
 ))}
 </div>

 <select
 value={selectedOption}
 onChange={e => setSelectedOption(e.target.value)}
 >
 <option value="">Choose an option</option>
 <option value="a">Option A</option>
 <option value="b">Option B</option>
 </select>

 <input
 value={lazyInput}
 onChange={e => setLazyInput(e.target.value)}
 onBlur={() => console.log('Blur event for lazy behavior')}
 />

 <input
 type="number"
 value={numberInput}
 onChange={e => setNumberInput(Number(e.target.value))}
 />

 <input
 value={trimmedInput}
 onChange={e => setTrimmedInput(e.target.value.trim())}
 />

 <button type="submit">Submit</button>
 </form>
 );
}

Comparison Summary

Vue's v-model reduces boilerplate for form handling, while React's controlled components give you explicit control over every input value.

Component Communication: Props and Events

Vue 3 Props and Emits

<!-- ChildComponent.vue -->
<script setup>
// Define props
defineProps({
 title: {
 type: String,
 required: true,
 default: 'Default Title'
 },
 count: {
 type: Number,
 default: 0
 },
 items: {
 type: Array,
 default: () => []
 }
});

// Define emits (for parent-to-parent communication)
const emit = defineEmits(['update', 'delete', 'custom-event']);

function handleUpdate() {
 emit('update', { id: 1, action: 'updated' });
}

function handleDelete(id) {
 emit('delete', id);
}
</script>

<template>
 <div>
 <h2>{{ title }}</h2>
 <p>Count: {count}</p>
 <button @click="handleUpdate">Update</button>
 <button @click="$emit('custom-event', 'data')">
 Emit Custom
 </button>
 </div>
</template>

<!-- ParentComponent.vue -->
<script setup>
import { ref } from 'vue';
import ChildComponent from './ChildComponent.vue';

const message = ref('Hello from parent');

function handleUpdate(data) {
 console.log('Update received:', data);
}

function handleDelete(id) {
 console.log('Delete item:', id);
}
</script>

<template>
 <ChildComponent
 title="My Component"
 :count="5"
 :items="['a', 'b', 'c']"
 @update="handleUpdate"
 @delete="handleDelete"
 />
</template>

React Props and Callbacks

// ChildComponent.jsx
function ChildComponent({ title, count, items, onUpdate, onDelete, onCustom }) {
 return (
 <div>
 <h2>{title}</h2>
 <p>Count: {count}</p>
 <button onClick={() => onUpdate({ id: 1, action: 'updated' })}>
 Update
 </button>
 <button onClick={() => onDelete(1)}>
 Delete
 </button>
 <button onClick={() => onCustom('data')}>
 Emit Custom
 </button>
 </div>
 );
}

// ParentComponent.jsx
import { useState } from 'react';
import ChildComponent from './ChildComponent';

function ParentComponent() {
 const [message] = useState('Hello from parent');

 function handleUpdate(data) {
 console.log('Update received:', data);
 }

 function handleDelete(id) {
 console.log('Delete item:', id);
 }

 return (
 <ChildComponent
 title="My Component"
 count={5}
 items={['a', 'b', 'c']}
 onUpdate={handleUpdate}
 onDelete={handleDelete}
 />
 );
}

Key Differences

  • Vue uses defineProps macro for type-safe props
  • Vue uses defineEmits for custom events
  • React passes functions as props for parent communication
  • Both support props validation and default values

Best Practices for React Developers Learning Vue 3

Mindset Shifts

  1. Templates are not JSX: While JSX blends logic and markup, Vue templates are declarative HTML with special directives. Embrace the template syntax rather than fighting it.

  2. Reactivity is automatic: Unlike React's useEffect dependency arrays, Vue's reactivity system automatically tracks dependencies. Trust the system, but understand its boundaries.

  3. Composition groups related logic: Instead of hooks like useEffect scattered through a component, use composables to group related functionality.

Common Mistakes to Avoid

<!-- Mistake: Mutating props -->
<script setup>
const props = defineProps(['initialCount']);

// Wrong - props are read-only
// props.initialCount = 5;

// Correct - copy to local ref
import { ref, watch } from 'vue';
const count = ref(props.initialCount);
watch(() => props.initialCount, (newVal) => {
 count.value = newVal;
});
</script>

<!-- Mistake: Forgetting .value in script -->
<script setup>
import { ref } from 'vue';
const message = ref('Hello');

// Wrong - this won't update
// message = 'New message';

// Correct
message.value = 'New message';
</script>

<!-- Mistake: Using v-for without :key -->
<template>
 <!-- Wrong - Vue needs unique keys for proper diffing -->
 <!-- <div v-for="item in items">{{ item.name }}</div> -->

 <!-- Correct -->
 <div :key="item.id" v-for="item in items">{{ item.name }}</div>
</template>

Performance Best Practices

  • Use shallowRef for large objects that don't need deep reactivity
  • Memoize expensive computed values
  • Use v-show for frequently toggled elements
  • Lazy load routes and components with defineAsyncComponent

Tooling and Ecosystem Differences

Vue 3 Tooling

ToolPurpose
ViteNext-generation build tool, incredibly fast
Vue DevToolsBrowser extension for debugging
Vue Language Features (Volar)Official VS Code extension
PiniaRecommended state management
Vue RouterOfficial routing solution

React Tooling

ToolPurpose
ViteAlso supports React with excellent performance
React DevToolsBrowser extension for component debugging
Redux ToolkitRecommended state management
React RouterDominant routing solution

Both ecosystems have mature tooling with similar capabilities. The choice often depends on team familiarity and specific project requirements.

Performance Comparison Considerations

Bundle Size

Vue 3's tree-shakeable core means you only pay for what you use. React similarly benefits from tree shaking, though the core React package has a baseline size.

Runtime Performance

Both frameworks perform comparably for typical applications. Vue's fine-grained reactivity can be more efficient for fine updates, while React's concurrent features offer sophisticated scheduling.

Optimization Strategies

Vue 3 optimizations:

  • Use shallowRef for objects that don't need deep reactivity
  • Use computed with proper dependencies
  • Lazy load components with defineAsyncComponent
  • Use v-memo for template memoization

React optimizations:

  • useMemo for expensive computations
  • useCallback for stable callback references
  • React.memo for component memoization
  • useDeferredValue and useTransition for non-blocking updates

Making the Choice: When to Use Which

Choose Vue 3 If:

  • Your team prefers template-based syntax
  • You want excellent TypeScript support out of the box
  • Fine-grained reactivity appeals to your mental model
  • You value single-file component organization
  • You want gentle learning curve for junior developers

Choose React If:

  • Your team is already familiar with React patterns
  • You need the largest ecosystem and job market
  • JSX-based logic-in-templates is your preference
  • You want maximum flexibility in component patterns
  • Integration with React Native is a priority

Both Are Valid Choices

Both Vue 3 and React are mature, performant frameworks capable of building excellent applications. The best choice depends on your team's experience, project requirements, and personal preferences.
