Architecture and Performance

Now let‘s compare React and Vue‘s underlying architectures and rendering pipelines to see how they impact performance.

Virtual DOM Implementations

Both React and Vue use a virtual DOM (VDOM) to efficiently update the UI by minimizing direct manipulation of the actual DOM. However, they have some differences in how they implement this.

React‘s VDOM is a lightweight representation of the actual DOM. When a component‘s state changes, React creates a new VDOM tree and compares it to the previous one (a process called "diffing") to determine what needs to be updated in the real DOM.

Vue, on the other hand, uses a template-based VDOM. It compiles templates into render functions that return a VDOM tree. Vue then caches these render functions and only re-renders when necessary. Compared to React, Vue has a slightly lighter-weight VDOM implementation.

Rendering and Reactivity

In React, rendering is always triggered by a state change. When a component‘s state updates, React re-renders the component and its children. React components can also have side effects that run after each render, using the useEffect hook.

Vue automatically tracks dependencies between state and the DOM. When a reactive state changes, Vue figures out the minimal components to re-render. This is similar to React, but Vue‘s reactivity system has some additional optimizations.

For example, Vue caches the template‘s render function and only generates a new one if the template changes. Vue also uses a flat VDOM tree format optimized for traversal. These help make Vue‘s rendering slightly faster than React‘s.

Performance Benchmarks

To quantify the performance differences between React and Vue, let‘s look at some benchmarks. One popular benchmark is js-framework-benchmark, which measures metrics like startup time, memory usage, and update duration.

Here are the results (averaged over 20 runs) for the latest versions of React (18.2.0) and Vue (3.2.47) on a MacBook Pro with an M1 Pro chip and 32GB RAM:

Metric	React	Vue
Startup time	61.3ms	50.9ms
Memory usage	7.1MB	5.0MB
Update duration	59.3ms	47.6ms

Source: js-framework-benchmark (keyed results)

In this benchmark, Vue slightly outperforms React across the board – with faster startup, lower memory usage, and quicker updates. However, the differences are relatively minor overall.

It‘s worth noting that benchmarks like this have limitations and may not reflect real-world performance. Factors like the complexity and size of an app, the use of third-party libraries, and the structure of the components can all impact performance.

In practice, both React and Vue are capable of excellent performance when used optimally. Techniques like lazy loading, code splitting, memoization, and virtualized lists can help minimize bundle sizes and improve the user experience.

Ecosystem and Tooling

A framework‘s ecosystem – including its libraries, tools, and community resources – is an important factor in its overall developer experience. Let‘s compare React and Vue‘s ecosystems.

State Management

For large applications with complex states, both React and Vue benefit from using a centralized state management solution. The main options are:

• React: Redux, MobX, Recoil
• Vue: Vuex, Pinia

Redux is the most popular state management library for React, known for its strict unidirectional data flow and immutable state. MobX takes a more flexible, mutable approach, while Recoil aims for minimal boilerplate.

For Vue, Vuex has been the go-to for state management, but the newer Pinia is gaining traction as a more lightweight and modular alternative.

Routing

For multi-page applications, both React and Vue offer official routing libraries:

• React: React Router
• Vue: Vue Router

React Router and Vue Router provide declarative APIs for mapping routes to components, with support for features like nested routes, route guards, lazy loading, and scroll restoration.

Component Libraries

React and Vue both have a wide variety of component libraries available, offering pre-built, customizable UI elements. Some popular options:

• React: Material UI, Ant Design, Chakra UI, React Bootstrap
• Vue: Vuetify, Element Plus, Quasar, Buefy

These libraries provide components for common UI patterns like forms, buttons, modals, and more, helping speed up development and maintain visual consistency.

Full-Stack Frameworks

For full-stack applications with server-side rendering (SSR) or static site generation (SSG), there are frameworks built on top of React and Vue:

• React: Next.js, Gatsby
• Vue: Nuxt.js, Gridsome

These frameworks handle aspects like routing, data fetching, and code splitting, abstracting away the complexity of configuring SSR or SSG manually. They also offer features like automatic code splitting, prefetching, and more.

Testing

Both React and Vue have well-established testing solutions, with frameworks like Jest, Mocha, and Chai commonly used for unit and integration tests.

For React, libraries like Enzyme and React Testing Library provide utilities for shallow rendering, querying, and interacting with components in tests.

Vue offers an official Test Utils library for testing Single File Components, as well as integrations with testing frameworks. Vue Test Utils provides functions for mounting, mocking, and asserting Vue components.

Use Cases and Case Studies

To understand how companies are using React and Vue in production, let‘s look at some prominent examples.
