Primary Sides of Comparison React.js vs Vue.js

React.js was created by Meta (ex-Facebook) as a tool to solve the problem with performance and organization of code in complex user interfaces. The main goal of developing React was to simplify the UI update and improve the responsiveness of the interface.
On the other hand, Vue.js was created by Evan You when he worked at Google. The framework appeared as a reaction to the existing Angular complexity. He sought to create a more flexible and intuitively understandable tool that could meet the needs of small teams and start-up cases.
We formed 5 criteria for two technologies comparison, on which development team can decide, what is the difference between React and Vue.
Structure and Architecture
React: React is built on components that allow the interface to break into independent, repurposed parts and uses Virtual DOM. React also supports JSX syntax, allowing you to mix different technologies such as HTML and JavaScript, making the development more declarative and user-friendly. One of the features of React is its one-way data flow, which makes state management in large applications more predictable.
Vue: Vue also uses a component approach, but allows the use of templates, which makes it easier for developers who are used to HTML to understand the code structure. Vue supports two-way data binding "out of the box", which simplifies the synchronization of data between model and presentation, especially in forms. It is designed for simplicity and supports a softer entry threshold for new users.
In Vue vs React comparison, React is therefore focused on functionality and versatility, while Vue is focused on simplicity and speed.
Syntax Peculiarities and State Management
React: In React, components are defined as functions or classes that use JSX for markup. State management can be implemented with built-in hooks such as useState and useReducer, which are suitable for small applications. However, for more complex projects, the Context API or third-party libraries such as Redux and Zustand are often used. As far as state management is concerned, Redux allows for centralized management of the state of all React-based applications, making it suitable for large, high-load applications. The main advantage of this approach is the predictability and simplicity of tracking changes in status.
Vue: In Vue, the syntax is more familiar to those who are skilled in the classical markup language. The markup is in <template>, data is stored in <data> and methods are stored in <methods>. This allows the experienced developers to quickly understand where logic, data and layout are located. The Vue state is managed by the Vuex library, which is built on the principles of Flux and is similar to Redux. This library supports modules, which allowing structure the app state and divide it into logical parts, which is especially usable in large applications.
Vue syntax is more user-friendly for beginners, whereas React allows you to use powerful JavaScript capabilities thanks to JSX. Redux provides more control over the state but requires additional configuration, whereas Vuex is better integrated into Vue and is easier to learn. For large applications with high requirements the state of Redux may be preferred, but for medium and small projects Vuex is a great choice.
Routing System
React: React does not initially include a built-in routing system, so developers often use React Router - a library that supports routing and allows easy adding of pages to SPA. React Router provides flexible options for configuring dynamic routes, transitions, lazy boot and other features needed to build complex user interfaces. This approach offers agility but requires extra effort for customization.
Vue: Vue Router is the official routing library for Vue.js, which integrates with Vue "out of the box". Vue Router supports two-way binding, so page navigation and routing is as easy as possible for developers. It also allows you to use such functions as nested routes and lazy loading. Vue Router is designed specifically for Vue, which makes it more easy-to-use.
React Router is powerful and flexible, but requires additional configuration, whereas Vue Router integrates with Vue and is easier to use, which reduces the number of code and errors during configuration.
Vue vs React Performance
React: React uses Virtual DOM, which allows for efficient user interface update. When the component state changes, React creates a virtual version of the DOM, calculates the changes and adds them to the real DOM. This process, although efficient, can become complex in a large application with many components. RJS also supports optimization through mechanisms like shouldComponentUpdate and memorization for more efficient rendering.
Vue: Vue also uses Virtual DOM, which makes its performance comparable to React. However, Vue offers built-in two-way binding, which simplifies the management of the state and reduces the amount of manual code. This approach reduces the load on the processor and allows faster updating of data in the interface.
Vue vs React performance shows similar for most standard tasks. React provides more opportunities for manual optimization, which can be useful for high-load projects, whereas Vue is automation oriented and requires less code to improve performance.
Ecosystem & Community Support
React: React.js vs Vue.js has a huge ecosystem, as it is widely used by large companies. His popularity has led to the building of many tools and libraries that help in development - for example, React Native for mobile applications, Next.js for server rendering and static site creation, as well as many third-party libraries for data handling, animation and routing. React Community is actively maintained and developed, providing stable documentation as well as a variety of courses and training materials.
Vue: Vue also has an active community, but the fame of Vue vs React popularity is quite less. The main libraries, such as Vuex and Vue Router, are developed and maintained by the Vue team. The Vue community is actively developing plugins and packages that make the Vue ecosystem very flexible and extensive.
The React ecosystem is more extensive and rich in tools and libraries, making it more suitable for large corporate projects. Vue, in turn, offers a less-burdened ecosystem with strong support that is particularly convenient for startups and small teams.
