Angular vs React: How to Choose the Right Technology
Angular vs React? The never-ending battle between these two leading front-end frameworks has been vicious for years. So which is the right choice for your next project?
The Angular vs React dilemma arises every time front-end development is required. The answer depends on many factors, as even front-end developers themselves have been debating the question for many years.
This article will provide you with a detailed overview of React vs Angular 2019. We address their history, key differences, core languages, and features to help you make the Angular vs React decision more quickly and simply.
Angular and React: The Most Popular Front-End Frameworks
Angular and React are two of the most popular technologies on the market. They made it into the top three front-end frameworks developers chose in 2018. Despite their differences, they serve the same purpose – the creation of websites and web applications. The primary purpose of utilizing Angular or React is to enable developers to reuse, refactor, and maintain code by dividing it into small components – the so-called component-based architecture.
React vs. Angular: The Brief History
Six years later in 2016, Angular had a total makeover. Google completely rewrote the Angular framework with TypeScript, a relatively new programming language.
Both technologies have been evolving side by side and finding their way into various projects, which we will talk about later on in the article.
Angular vs React: What is the Difference?
When defining what the difference between Angular and React is, we first need to take their architectures into account. Below you will find out the difference between a framework and a library.
React vs Angular: Factors to Consider
While considering Angular or React, remember that while they have much in common, their differences cannot be ignored. Before making any final decisions, you need to answer the question, “which tool better suits the needs of my project?”
Below you will find the main factors to consider when deliberating over the Angular vs React question.
The Pros and Cons of Angular Framework
Let’s start with the Angular framework. As we’ve already mentioned, it comes with many features right out of the box. You don’t have to spend time combining various technologies and libraries, which allows you to start developing a web application right away.
Here are the main benefits for you to consider:
Two-way data binding defines how easily developers can change UI elements. In the case of the Angular framework, every change in a UI element is automatically reflected in the corresponding change in model state.
RxJS, a library for asynchronous programming, is responsible for the handling of asynchronous operations and events, thus reducing the resources needed for these operations. A web application can simultaneously handle events independently. RxJS is compatible with many frameworks; however, knowledge of the library is essential for those who want to utilize the features Angular framework offers to the utmost.
Angular CLI is a command-line interface that serves as a tool for the fast generation and running of a project with a few commands. It reduces the time needed to create apps, add files, make tests, debug, and deploy. With Angular CLI, the update of an app to the latest Angular version is simple and can be fully automated. This is one of the most important factors to take into account when thinking about Angular vs React.
Angular Universal is the technology that enables the rendering of Angular applications on the server side. It is fully compatible with Angular CLI and supports some Node.js frameworks. It is an ideal solution for mobile devices that may lack processing power for client-side rendering.
Ivy render is a relatively new addition to the Angular framework. This new Angular rendering engine increases performance by compiling one file at a time. When generating the output, Ivy render takes into consideration only a component and its template, while ignoring dependencies.

- Testing is possible with a single tool. You can use Jasmine, Karma, and Protractor solutions for the thorough testing of an Angular app in browser.
Below you will find the main drawback to consider.
- Regular DOM is the main feature to consider. Unlike its counterpart, Angular opted to use Regular DOM instead of Virtual DOM, which may affect the performance of an app when dealing with a lot of data requests. For example, let’s say that you want to update a user’s data, like birth date. Instead of changing just that bit of information, Regular DOM updates the entire tree structure of HTML tables until it reaches the needed data - in our case, the birth date information. However, the Angular vs React performance depends heavily on code optimization.
React Library: Benefits & Downsides
ReactJS can show its full potential only when integrated with other tools and solutions. Some front-end developers name it a disadvantage, while others see it as the main feature of React library, which makes it highly flexible. The success of a project depends on the team behind it and their ability to choose the right technology stack.
Here are the benefits React offers:
Virtual DOM is considered to be faster, as compared to regular DOM, due to the ability to change parts of data without changing other parts of the HTML tree. This helps app development teams to make and track changes easily. This factor sometimes becomes determinative in an Angular vs React comparison.
Next.js is a framework for the server-side rendering of React applications. React applications can be rendered both on the client side and server side, freeing additional processing power for Virtual DOM.
Below you will find the main disadvantages of React you should consider before starting to develop a new application:
The one-way data binding that React utilizes prevents developers from easily making changes in the UI elements. This can be done only after the corresponding model state is changed. However, it is not a drawback; as a project grows, React offers a better data overview which results in hassle-free debugging.
Below you can see a table that summarizes all the information above:
|DOM||Real DOM||Virtual DOM|
|Rendering||Client/server side||Client/server side|
|App size (KB)||~ 500||~ 80|
|Types of Apps||SPA
Angular vs React: Which is Best for App Development?
So, what should you pay attention to when considering Angular vs React?
Angular often looks more attractive for software development teams in the Angular vs React overview since it offers the whole package of advantages that any full-fledged framework possesses. If the development timeline is the decisive factor for your project and you don’t have time to find technologies to combine, Angular is your go-to choice.
Choose Angular in the following situations:
- If your team is familiar with Java and C#, since these languages have much in common with TypeScript
- A project needs to be highly productive
- Development team prefers to use out-of-the-box solutions
- The application you intend to build is large-scale with a lot of features
React does not lag behind its main competitor and offers higher flexibility. While Angular is delivered with a set toolbox, React can be aligned to the needs of a specific project by adding additional tools and libraries. Here is why on should use React:
- You need to create a unique application with a high level of customization
- You don’t need to rush and can include research and selection of tools prior to starting the development process
- Your app will have a lot of dynamic, data-intensive, and constantly changing content
As the tech world has stepped into the era of microservices and microapps, picking the most suitable technology is vital for such projects. You should always consider the Angular vs React choice. TypeScript makes Angular a go-to solution for SPA (single page application) development. React offers more flexibility which is ideal for microapp and microservice development. Your decision in favor of Angular or React depends entirely on the type of project you have in mind.
