Exploring Vue.js: A React Engineer’s Perspective
Introduction
As a seasoned React engineer with five years of experience, my journey into the world of UI frameworks has been predominantly through React. I have a deep appreciation for React and have found it to be an excellent tool for building user interfaces. However, the dynamic landscape of front-end development led me to explore other contenders in the field, and one framework that caught my attention is Vue.js.
In this comprehensive exploration, we will delve into various aspects of Vue.js, comparing it with React and highlighting key differences. From philosophical distinctions to practical features, this deep dive aims to provide insights into how Vue.js operates and, more importantly, how it can enhance the life of a UI engineer.
Different Philosophies
The foundational disparity between Vue.js and React lies in their self-descriptions and marketing approaches. React positions itself as “a JavaScript library for building user interfaces,” while Vue.js identifies as a “progressive JavaScript framework.” This seemingly subtle distinction sets the tone for the fundamental differences in how each framework approaches UI development.
Understanding this contrast is crucial as it lays the groundwork for the subsequent exploration of their respective features and functionalities. React, being a library, follows a leaner approach, focusing on specific tasks and excelling in them, while Vue.js, as a framework, offers a more comprehensive and exhaustive set of tools.
Single File Components
Components are the building blocks of both Vue.js and React, yet their implementation differs. Vue.js introduces the concept of “Single File Components,” providing an integrated approach to handling UI (HTML), behavior (JavaScript), and appearance (CSS) in a single file. The simplicity of Vue.js’ Single File Components is evident in its concise structure:
html
<template>
<p>{{ greeting }} World!</p>
</template>
module.exports = {
data() {
return {
greeting: ‘Hello’,
};
},
};
</script>
p {
font-size: 2em;
text-align: center;
}
</style>
React, on the other hand, separates UI and behavior by default, requiring additional libraries like Emotion or Styled Components for styling. While React’s community offers rich solutions, Vue.js provides built-in support for styling, simplifying the development process.
Officially Supported Related Libraries
Large UI applications often demand additional functionalities, such as routing and state management. Vue.js addresses these needs with officially supported libraries—Vue Router for routing and Vuex for state management. The explicit mention and integration of these libraries within the Vue.js ecosystem provide a structured approach for engineers, instilling confidence in the longevity and reliability of these solutions.
In contrast, React’s community-driven ecosystem offers various solutions, but the absence of officially supported libraries may pose challenges for newcomers in choosing the right tools. Vue.js’ approach exemplifies a strategic commitment to providing robust solutions that align seamlessly with the core framework.
Style Guide
Vue.js distinguishes itself with a comprehensive style guide that not only answers common questions but also establishes best practices and guidelines for writing maintainable and approachable applications. Maintained and supported by Vue.js itself, this style guide serves as a valuable resource for developers, streamlining the development process and fostering consistency across projects.
The absence of an officially supported style guide in the React ecosystem is notable. Integrating such a guide could enhance the development experience for React engineers, offering a centralized reference for best practices and community-vetted patterns.
Class and Style Bindings
Vue.js elevates the developer experience by seamlessly integrating styling into its components. The built-in support for class bindings and inline styles simplifies the handling of styles within Vue.js templates. React, while versatile, requires external libraries like classNames for similar functionality. Vue.js’ approach, directly from the documentation, demonstrates the elegance of incorporating styles:
html
<div
class="static"
:class="{ active: isActive, 'text-danger': hasError }"
></div>
This inherent support for styling in Vue.js showcases the advantages of a framework that controls its template syntax.
Slots
Vue.js introduces the concept of slots to handle the rendering of multiple arbitrary children within a component. This approach provides clarity and flexibility, allowing developers to denote where content should be placed inside a component. Vue.js’ use of slots, inspired by the Web Components spec draft, simplifies the structuring of components and offers a cleaner API:
html
<base-layout>
<template #header>
<h1>Here might be a page title</h1>
</template>
<p>A paragraph for the main content.</p>
<p>And another one.</p>
</template>
<p>Here’s some contact info</p>
</template>
</base-layout>
This approach contrasts with React’s reliance on props for rendering children, demonstrating Vue.js’ commitment to providing shorthand for common tasks.
Directive Modifiers
Vue.js introduces Directive Modifiers, a feature that enhances the flexibility and readability of directives within templates. Directives, identified by the v- prefix, gain additional functionality through modifiers, simplifying common tasks associated with reactive DOM manipulations. For instance, Vue.js offers modifiers for event handlers, providing a concise syntax:
html
<a @click.stop="doThis"></a>
React, in contrast, would typically require the use of helper functions or custom components to achieve similar functionality. Vue.js’ directive modifiers offer a clean and developer-friendly way to handle common tasks associated with directives.
Form Input Bindings
The v-model directive in Vue.js introduces a noteworthy characteristic when binding data to form input elements. Vue.js internally manages different properties and events for various input elements, abstracting away the intricacies of data synchronization. A comparison between React and Vue.js in handling form input bindings reveals the simplicity of Vue.js:
html
<input type="input" value={message} onChange={onChange} />
<input type=“input” v-model=“message” />
Vue.js’ approach simplifies the code, allowing developers to focus on the logic rather than the nuances of data synchronization.
Custom Directives
Vue.js empowers developers with the ability to create custom directives, offering a level of abstraction beyond components. While components remain the primary form of code reuse and abstraction, custom directives, such as Vue.js’ v-focus directive for auto-focusing an input element on mount, showcase the flexibility of Vue.js:
javascript
const app = Vue.createApp({})
app.directive('focus', {
mounted(el) {
el.focus()
}
})
<input v-focus />
In contrast, React might require a custom component for a similar task, showcasing Vue.js’ ability to provide lightweight solutions for specific use cases.
Written in TypeScript
A notable aspect of Vue.js is its recent rewrite in TypeScript, making TypeScript support a first-class feature within the framework. While the choice of the underlying language might not drastically impact a developer’s experience, having a framework written in TypeScript can enhance the overall TypeScript support and integration.

Closing Thoughts
While this exploration sheds light on the strengths of Vue.js and its potential influence on React, it is essential to emphasize that the goal is not to abandon React but to recognize and appreciate the unique features of Vue.js. As a React enthusiast, I find the library-centric nature of React enjoyable and efficient.
However, there is room for improvement and inspiration. React could benefit from adopting certain aspects of Vue.js, such as the implementation of an officially supported style guide. This exploration aims to broaden perspectives, sparking conversations within the developer community and fostering continuous improvement in UI frameworks.
In conclusion, Vue.js has certainly introduced me to intriguing approaches and features that enhance the development experience. As the world of front-end development continues to evolve, cross-pollination of ideas between frameworks is a positive catalyst for innovation and improvement.
