By the end of this article, you'll have enough knowledge to make an informed decision about whether to choose React or Vue for your next project. So let's dive in!
What Is Vue?
Vue, also known as Vue.js, is a web development technology commonly used to develop interactive and complex user interfaces in single page web applications. According to its website, Vue is “the progressive JavaScript framework for building web user interfaces.”
The framework uses a model-view-viewmodel (MVVM) architectural pattern, which separates the graphical user interface from the business logic of your application.
Vue is free and open-source, developed by Evan You, an ex-Google employee, in 2013. The idea for Vue came after Evan worked with Angular.js and shared his thoughts about it: "I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight without all the extra concepts involved.”
Today, Vue has become one of the most widely used frontend frameworks in web development, rivaling popular tools such as React.js and Angular.js. It is known for its simplicity, easy-to-understand underlying concepts, and short learning curve for beginners. Vue offers a strong basis for creating complex and performant apps that match your unique demands, regardless of your level of experience as a developer or where you are in the learning process.
Features of Vue
Vue's popularity stems from its array of features that make it simple, flexible, and easy to use for developers at different levels of experience. Vue offers a wide range of tools for creating dynamic, responsive, and complex web applications. In this section, we'll explore some of the exciting features that give Vue its acclaimed superpowers.
Component-Based Architecture
Vue uses a component-based architecture that divides the user interface into independent and isolated entities. This approach enables developers to reuse code components throughout the entire application. Components are a fundamental building block of many Vue applications. They allow for the separation of concerns and provide a straightforward way to manage large and complex applications seamlessly.
For example, here is how you would typically write a component in Vue:
< script >
export default {
name: 'Hello-World'
} <
/script>
<
template >
<
div >
Hello world!
<
/div> <
/template>Reactivity and Two-Way Data Binding
Reactivity is one of the key features of Vue that makes it popular among developers. Essentially, reactivity is a programming paradigm that allows developers to adjust to changes in a declarative manner. In Vue, you can update the Document Object Model (DOM) as you modify your application state, which is essentially just JavaScript objects. Reactive and dynamic user interfaces are important parts of modern web app development, and Vue handles them very well.
In Vue, two-way data binding means that data is automatically synchronized between the model and the view layers. Put simply, when the data in the model changes, it automatically updates the view, and when the data in the view changes, it automatically updates the model. A good example of this is the v-model directive, which is commonly used to sync data between an input field and a state object in order to create interactive forms in Vue applications.
Integration with Other Tools
By default, Vue provides some basic but powerful functionalities for creating interactive and dynamic single-page applications. Additionally, it can be used with any other JavaScript library if you want additional capabilities. Some examples of these libraries include:
Vue Router - A JavaScript library for implementing navigation in a single-page application.
Vite - A build tool that provides a faster and improved developer experience for creating Vue projects.
Vuetify - A material design component framework for Vue. It provides a set of UI components and styles that can be used to build beautiful and responsive user interfaces with little or no configuration.
Vuex - A state management library in Vue that serves as a centralized store of data for all the components in your application.
Free and Open-source
Vue is a powerful and flexible framework for building web applications that offers a wide range of features that make it simple, flexible, and easy to use for developers at different levels of experience. One of the key advantages of Vue is that it is free and open-source, which means that its source code is available for anyone to use, modify, or research. This not only makes Vue accessible to developers of all skill levels, but it also enables collaboration from the diverse community of Vue users who contribute to the project and make it sustainable.
The open-source nature of Vue also means that developers can modify the framework to suit their specific needs, which gives them greater control over their application's functionality and design. This level of customization is particularly useful for developers who are building complex web applications that require a high degree of flexibility and scalability.
In addition to being free and open-source, Vue is also known for its simplicity, easy-to-understand underlying concepts, and short learning curve for beginners. This makes it an ideal choice for developers who are just starting out in web development, as well as those who are looking for a more streamlined and intuitive approach to building web applications.
Overall, Vue's free and open-source nature is one of its key advantages, as it not only makes the framework accessible to developers of all skill levels, but it also enables greater collaboration and customization, which can help developers create truly unique and powerful web applications that meet their specific needs and requirements.
Templates
Templates in Vue use an HTML-based syntax for writing application markup using different methods, such as text interpolation, raw HTML, or JavaScript expressions. These templates can be compiled and rendered to the DOM, allowing you to build complex and dynamic user interfaces with ease.
For instance, Vue templates can help you render data from an array or object of remote data, handle user input events, and conditionally render content based on the component's state.
Most of the time, you'll find yourself using templates in Vue. The structure of a component's view is defined by a template, which is essentially a string of HTML that may include placeholders for dynamic data and application logic.
Virtual DOM
Vue's rendering system is based on a programming concept called virtual DOM (VDOM), which is an abstract representation of the real DOM. The virtual DOM is a memory-resident UI representation that is kept in sync with the real DOM. Since modern JavaScript applications tend to be highly interactive, there's a need to keep the user experience smooth without sacrificing performance.
Here's how the virtual DOM works in Vue. When the application data or state of a component changes, Vue automatically updates the in-memory virtual DOM of the component's HTML markup. The virtual DOM then calculates the difference between the previous state of the component's markup and the new state and determines the minimum set of changes required to update the actual DOM. This approach only updates the real DOM with the necessary UI changes instead of updating the entire DOM tree, which can be slow and inefficient.
The VDOM in Vue is a technique borrowed from React.js and is used by frontend frameworks such as Elm.
The main idea behind the VDOM is to provide a faster and declarative approach to manipulate, create, or update UI structures while leaving the rather slow and expensive direct manipulation of the DOM to the renderer.
Multipurpose
Vue is a flexible and compatible technology for many web development use cases. It provides a powerful set of tools for building dynamic and reactive user interfaces, making it a great choice for single-page applications, such as e-commerce sites.
In addition, Vue can be used for Server Side Rendering (SSR) to render the initial state of an application on the server, improving performance and SEO. For Static Site Generation (SSG), Vue can generate static HTML pages that can be served directly to users without the need for a backend server, making it a great fit for JAMStack.
Vue can also be used for desktop app development with tools like Electron, or mobile app development using a framework like Ionic Vue. All in all, Vue offers a flexible and powerful toolset for web development that can be adapted to a wide range of use cases and requirements.
What Is React?
React.js, commonly referred to as React, is a JavaScript frontend library used to create performant and interactive user interfaces for web applications. Developed at Facebook, React was first released to the public in 2013 and has since become one of the most powerful and widely-used libraries for building web applications.
Facebook originally created React for a couple of reasons. The main reason was to manage the bottlenecks that arose from creating complex software, such as the Facebook Ad platform. Another reason was to improve the performance and maintainability of their own web applications. The web was evolving, with interactive and complex user interfaces becoming more common, and Facebook didn’t want to fall behind in this development, especially since they were building an application at the forefront of this evolution - namely, Facebook.
Features of React
So, what are the features of React that make it so popular and a leading choice in web development? In this section, we will go through some of the most important features of React that put it at the forefront of web development.
Virtual DOM
The virtual DOM is one of the most powerful features of React and is responsible for its performance in complex web applications. According to the React documentation, "The virtual DOM (VDOM) is a programming concept where an ideal, or 'virtual', representation of a UI is kept in memory and synced with the 'real' DOM by a library such as ReactDOM. This process is called reconciliation."
The virtual DOM makes working with React declarative. This means that you describe what you want your application to look like, rather than how to make it look that way. React also uses the virtual DOM to create a virtual representation of your app's UI, which it then renders to the actual DOM. Because React takes care of rendering the UI, you don't need to worry about low-level details like updating the actual DOM manually, which can be complicated and slow down your application's performance.
Component-Based Architecture
React's component-based architecture is a key feature of the framework. This architecture is a framework for building software based on modular and reusable components.
Components in React are pieces of React code that are encapsulated into a single file, which represents a part of the app UI. Although components are often independent, they can share their state or data with other components through properties and events. This separation of concerns makes it easy to build complex UIs from small, reusable components, rather than having to write all the application code in a single file.
Another benefit of the component-based architecture is that it makes it easier to work across your codebase. By breaking down your application into smaller, modular components, you can focus on one piece of functionality at a time and avoid getting overwhelmed by the complexity of the entire application.
For example, here's how to create a functional component in React that increments a counter when a button is clicked:
import React, {
useState
} from 'react';
function Counter() {
const [count, setCount] = useState(0);
function handleClick() {
setCount(count + 1);
}
return ( <
div >
<
p > Count: {
count
} < /p> <
button onClick = {
handleClick
} > Increment < /button> <
/div>
);
}JSX
JSX is a syntax extension to JavaScript that React uses to describe the appearance of your UI. Essentially, it allows you to write HTML-like code within your JavaScript, making it easier to create complex UIs with dynamic content.
While not strictly necessary in React, JSX enables you to write readable, declarative, and easily comprehensible code, particularly when working with React components.
For instance, consider the following example of React code written in JSX:
const element = ( <
h1 className = "greeting" >
Hello, world!
<
/h1>
);Compared with the same code written without JSX:
const element = React.createElement(
'h1', {
className: 'greeting'
},
'Hello, world!'
);In essence, JSX enables you to write composable, maintainable, and easy-to-understand React code.
One-Way Data Binding
One-way data binding, also known as unidirectional data flow, is a model where data flows in a single direction: from the parent component to its children. The main idea behind this approach is to help developers build scalable and maintainable applications that are easy to write and debug.
With this approach, only the parent component can pass data down to its children as props. The children components cannot modify the data directly. Instead, if a child component needs to update the data, it sends a message to the parent component. The parent then updates the data and passes it back down to the children.
Large and Growing Ecosystem
Since its release in 2013, React has gained an enormous following and a thriving ecosystem of developers, tools, and resources. Its free and open-source nature has made React one of the go-to choices for building modern web applications.
Moreover, React-based libraries and tools cover a wide range of features, including state management, routing, animation, styling, and testing. This allows you to create virtually anything you can imagine without going through the hassle of building from scratch.
Multipurpose
React's flexibility is one of its most exciting features, contributing to its widespread popularity. It can be utilized to build single-page applications, statically generated sites, or server-side rendered sites.
Furthermore, React is a versatile tool that can be applied to a variety of use cases beyond web development. Examples include building mobile apps with React Native, desktop applications with Electron, or creating desktop applications for macOS, Windows, and Linux.
Vue vs. React: Head-to-Head Comparison
As previously discussed, Vue and React are two popular JavaScript technologies used for building modern web applications. While they share some similarities, there are also key differences between the two that can influence your decision on which to use for your project. In this section, we will explore the similarities and differences between Vue and React, as well as their unique use cases, advantages, and disadvantages.
Similarities Between Vue and React
JavaScript-Based - React and Vue are both built on JavaScript, which partly contributes to the rivalry between them.
Virtual DOM - React and Vue both use a virtual representation of the actual DOM, called virtual DOM, under the hood. This method of rendering the UI eliminates performance bottlenecks and abstracts away manual DOM manipulation that can be slow and expensive.
Component-Based Architecture - Both Vue and React follow a component-based architecture, enabling developers to build complex UIs by breaking them down into smaller, reusable components that can be shared and reused across an entire application.
Lifecycle Hooks - React has "lifecycle methods" which are now known as hooks, allowing code to be executed at set points during a component's lifetime. Vue has its own system of reactive properties and lifecycle hooks that achieve similar functionality to React's hooks.
Integration with Other Tools - Both technologies support Typescript and Redux, a popular state management library for JavaScript.
Versatility - React and Vue offer a wide range of use cases, including mobile and desktop application development. Additionally, they can also be used for building Progressive Web Applications (PWAs). For instance, React has Next.js, a popular React framework for building scalable web applications, and Gatsby for building statically generated sites.
Differences Between Vue and React
Framework vs. Library - Vue is a complete JavaScript framework, while React is a JavaScript UI library. Vue includes many features for building a complete app by default, whereas React focuses solely on the UI part of an application and requires a few additional libraries to create a complete app.
Code Syntax - Developers familiar with HTML will find Vue's template-based syntax simpler to grasp and understand. React, on the other hand, uses JSX, which combines HTML and JavaScript into a single file.
Creator - Vue was created by Evan You, a former Google employee and lone software engineer who became frustrated after using Angular. React, on the other hand, was created by Jordan Walke, a software engineer at Meta (formerly Facebook).
Size - Powerful but lightweight, Vue applications tend to be generally smaller compared to React applications with the same feature sets.
Learning Curve - React can be complex and has a steep learning curve for beginners. It requires advanced knowledge of application development and JavaScript. Vue, on the other hand, is simpler and easier to understand for beginners, thanks to its intuitive approach to code writing and solid documentation.
Popularity and Acceptance - According to the 2022 State of JS survey, 81.8% of respondents use React in their tech stack, compared to 46.2% using Vue. Additionally, 50.7% of people showed interest in picking up Vue, while 47.2% expressed interest in React.
When to Use Vue over React?
Vue is a framework and, unlike React, it has some superior capabilities that are lacking in a library such as React. Most of the required functionalities in a fully-fledged application are often built in and abstracted away by a framework like Vue. Vue is best suited for novice developers or anyone looking to build an application as quickly as possible.
There are no limits to the kinds of applications that can be developed with Vue, from e-commerce sites to social networking apps and user dashboards.
