React Vs Vue: Which One To Choose In 2021?

React vs Vue

These days web applications are ruling the development landscape and will continue in the future too. When it comes to choosing Javascript frameworks and libraries, developers came up with many options including React and Vue. The challenging part is deciding to use Vue or react for use  in your tech stack. Both use a Virtual DOM and possess a reactive and component-based structure. Here we will compare two very popular web app frameworks React and Vue on the basis of various parameters such as, user-experience, performance, testability, security, developer availability and so on. Before digging to the comparison, let us see each one in detail.


React.js is an open-source javascript library used to build web apps with rich user interfaces. It offers flexibility to create reusable custom components that encourage rapid development processes. Also, it is user friendly due to its ability to allow quick rendering of a web page. This library promotes the development of light-weight and complex business applications.

One can create not only web apps with React.js, but also media sites, video streaming platforms, software as a service tools, mobile apps, desktop apps, progressive web apps, JAMstack sites etc. Paypal, BBC, Facebook, Netflix, Twitter are some of the examples of popular apps created with React.


It is a lightweight and flexible JavaScript-based framework that provides advanced web tools to develop modernistic SPAs and front-end web apps. Vue is also considered a versatile and progressive JavaScript framework because it allows change creation in an application code without influencing any core feature built and this provides an opportunity to create progressive UI. With decoupling, Vue also offers opportunities to extend functionalities of web app with customized modules and visual components.

One can create single-page apps, progressive web apps, small project apps, large scale enterprise apps, existing app design extension, existing app functionality extension with Vue. Behance, Gitlab, adobe portfolio, laravel spark, grammarly are some of the apps created with Vue.

React Vs Vue- A Comparison

1. Learning Curve-


React adopts the JSX format, where HTML is written in JavaScript. Though JSX is inline with functional programming, developers are saddled with the responsibility of figuring out this new approach. React heavily depends on other third party components for effective use. This can be an issue for developers since they news to grasp a lot of information just to get things done. React has a good documentation.


Vue is easy to learn as compared to React. It separates concerns so that web developers are already used to, decoupling HTML, CSS and JavaScript. Vue allows the use of JSX for those who want to adopt that style. It is easy to get accustomed with Vue because it picked out the good parts of React and Angular. So it is easy for developers from either of the two backgrounds to fit in perfectly. Vue has a well detailed documentation.

2. Performance-


React app’s performance is faster, a lightweight performance in user experience with individual components working in a fine functional way. It’s component based architecture helps to build more robust single page apps, reusability removes code clutter and reduced DOM manipulation speeds up the page loading. This reflects seamless app performance and pleasing user experience. Library works on updating the necessary changes to the webpage without reloading the entire page. Hence it eliminates the unnecessary loading of page and rather refreshes the data. To build react apps by setting some programming practice, you can use minimal approach.


When each new feature added or extension of a component, Vue app becomes more uncertain that makes it hard for the app to load faster. Whereas, this framework has a virtual DOM, that serves as the default tool which helps in app’s performance optimization. Lazy loading feature of Vue helps to improve load time. Vue deals with third-party library in an asynchronous way by automatically handling the critical dependencies by isolating the libraries into the ones that need to be included in the main application bundle and the ones that can be left in routes away from the core bundle. 

3. Architecture-


It doesn’t have a built-in architecture pattern. React caters to the view layer of app which is made with components. React components work as functions that render the underlying user interface as data changes. Continuous interaction between the users’ actions and state of app components makes internal architecture of Recat.js. The state of the React component is excellent when you need to build applications with limited functionality and scope. React is dependent on external libraries such as Flux, MobX, Reflux, Redux for building real-world applications.


It follows the ViewModel approach and supports the pattern on MVVM in case of developing large-scale apps. View part and Model part are connected in two-way binding.

Model- Functions like Model object of JavaScript. When the data object enters the Model part, the data instance is transformed into reactive elements to create appropriate storage layers discretely.

View- There is a management of DOM instances in the View part of Vue. It makes use of DOM-based templating to successfully creating root elements and correspond with required DOM components.

Viewmodel- It handles the synching necessity between Model and View part of code. This Object is the primary part to interact developers with code.

Architecture of Vue and its DOM structures are abstracted into parts- Filters and Directives. Vue is not a full-blown framework so it follows a View layer pattern, handling of app development is made simple and flexible.

4. Scalability-


React apps are made up of pure javascript so developers can depend on traditional easy to organize the code to make projects more scalable. This is a good framework for building scalable UIs pertaining to the concept of virtual DOM and component reusability.


Vue is preferred for developing small-time apps and not scalable apps regardless of its ability to extend app with its flexible tools. Scalability can be made possible by forking a vue app by breaking it into multiple multiple repositories to separate the app for convenient scaling as per requirement. As the architecture is little dynamic, scalability is achieved by using web packs and Mixin elements offered by Vue to override the code extending limitations.

5. Application Size-


It is a library and not a fully featured frontend framework like Angular. React’s app sizes are bigger as compared to other. Latest react versions have reduced bundle size by reducing app size by 30% to previous version.

It is a lightweight framework and so its app size might not be heavy like other frameworks. A simple Vue app has a size of between 50kB to 100kB. Vue CLI might make the app size appear large when it loads the code for first time due, but implementing lazy loading components, codes can be broken into smaller parts and improve load time. Tools such as NuxtJS, Vuex, Bit, Vue-router eliminate the need of code writing from scratch with effective state management that predicts unnecessary functions, codes and eliminates them.

6. Code Maintenance-


We know that react has component based architecture and it concentrates on building UI components, custom functionalities in user interface and optimally using logic to build functionalities. While developing app with React, you are developing functional and individual code snippets. Those snippets are reusable to other apps and various modules of the app. Dividing app into specific parts helps to manage app efficiently. 


Vue is ever-growing technology and is rising in pace against most frameworks that have existed for a long time. So maintaining a Vue app is not that much hard. Vue lacks good support, creating conventional coding practices help to overcome limitations and obstacles. Vue is future-proof considering its effortless integration abilities and code grafting continuity onto existing DOM and HTML mark-up with zero prerequisites.

When To Choose REACT?

  • You can choose react when you want to play around with many libraries, tools or ecosystems.
  • Prefer React to develop scalable apps without any hassle for testing and debugging.
  • Go with React to build complex app with better time-to-market.
  • You can build video streaming platforms and media sites effectively with React.

When To Choose VUE?

  • You can prefer Vue to build progressive web apps and single page apps.
  • Also, if you want to extend the functionality of existing apps, go with Vue.
