Nowadays, Angular and React are among the most commonly used tools among software developers, especially when it comes to building scalable, dynamic web apps. The goal of this article is to highlight the key differences between these two technologies to help web developers make an informed decision when choosing their preferred solution for a particular project.
So if you’re trying to figure out which one is best for your next project, keep on reading! We will take a look at how they stack up side-by-side in terms of concepts as well as functionality.
React.js vs Angular
When talking about angular, we will be talking about Angular 2 which is the newer version of AngularJS. This will also be the same for all other angular versions up till Angular 9.
Angular is an open-source framework that is used for creating web apps, hybrid apps and building single web pages. Angular is developed and maintained by Google itself and is essentially a tool kit that is developed on TypeScript. This kit has everything a developer needs to build large scale apps.
React on the other hand is maintained and developed by Facebook. It is a front end JS library that is used for creating UI (user interface). React uses declarative programming to create and declare UI states.
How Are Both Different
React has the advantage of real-time monitoring of apps while in development. Programmers can see how the app will look at the user end and how users will interact with the app. React is a reusable library which means it saves development time and has minimal chances of errors in coding.
React has two very pronounced features: The React virtual DOM and the JSX. More on these later.
Just like Angular, React is an open-source framework allowing anyone to download and modify the source code as per needs.
The libraries in React are very vast and cover-up for a brand range of programming needs. The libraries range from individual UI features to full-fledged templates that can help programmers to build user interfaces from scratch. No matter what kind of UI function a programmer is looking for, React is almost always likely to have it.
Angular however works very differently in terms of operation and functionality. This detailed comparison will show the key differences between Angular and React.
Angular Vs React: Technical comparison
Now we will compare Angular and React in terms of their features and performance.
DOM or Document Object Model allows programmers to access and change the layout of documents, their contents, as well as their structure. While both React and Angular are great for constructing robust front ends, they differ greatly in terms of how they operate.
The major difference between the two is that React uses a virtual DOM while Angular has a real DOM.
For instance, you want to update a user profile, and let’s say you want to change the email – React and Angular will take on the task in contrasting ways.
Angular will modify the whole tree structure of the HTML tables to update that one bit of information while React’s virtual DOM can update such minor changes without needing to rewrite the entire HTML code.
That is why rendering in React is much faster in React as compared to Angular. The way the real DOM works makes the apps slower especially when they have to deal with heavy data requests.
Data binding creates a relationship between the UI and logic. Angular uses both one way and two-way data binding while React only uses one-way data binding.
This largely changes the way data is represented in a tree. In React developers often have to nest the child components inside the parent components of the higher-order.
One-way data binding in React is much easier to debug and is more stable. However, Angular has both two ways and one-way data binding which makes it more flexible than React and is also much simpler to use.
The Ecosystem In React And Angular
Component Architecture In React
The way React builds user interfaces is by breaking them into different components. It is very simple to build UIs because you build piece by piece – it is almost similar to building Lego toys.
React allows building small components that have their own structure and state and then put them all together into a much more complex and functional application. While React will aid you with a major portion of your architecture, you are going to need multiple integrations and tools to get things done.
Here are some of them:
Redux is a popular state management library that makes building UIs simpler by maintaining the state in the memory that changes only in one direction. It also keeps track of actions that were previously dispatched, so it can handle possible data conflicts.
It has the following features: a single source of truth, debugger, preloaded with lots of dev tools, etc.
Redux is powerful and versatile, and is perfectly suited to building fast, scalable web applications. But like any new technology, it can be a little confusing until you get a hang of it.
Redux brings a certain amount of structure and complexity which can sometimes lead to frustration for developers who haven't had the opportunity to learn it yet.
Babel is a new all-in-one compiler. It helps you use the best technologies while taking away the pain of setting them up. It’s designed for everyone who uses web technologies.
Babel is the first enterprise-ready solution for engineering static and personalized React applications.
With this tool, developers can leverage the benefits of React.js to provide a better user experience (and reduce costs) with personalization, such as server-driven forms, inline validation, and a more fluid navigational experience. This JS library adds no build step to your code or workflow, making it an ideal solution for both cloud and on-premise products.
Webpack takes your code, through a plugin, and does all the things you need to do to get it ready to deploy (minify, compile, etc.)
It takes modules with dependencies and bundles them together into something smaller and more manageable.
This is useful and necessary for any serious application, as in bigger applications it's easy to have dozens (if not hundreds or more) of different modules inside your project.
It bundles your code and all of your dependencies into small packages to optimize load times and caching.
RxJS is an open-source, cross-platform Java library for working with JSON. This library is to be used in conjunction with JSON and provides several utilities for converting Java objects to JSON and vice versa.
Create React App
Create React App is a CLI tool that you can use to create new projects. It offers a standard configuration for your project, so you don’t have to worry about Webpack or Babel, and lets you focus on writing code.
The goal of the Create React App project is to lower the barrier to entry for React.js adoption and automate the setup process as much as possible. Instead of requiring that you configure Webpack yourself, Create React App does it for you with a single command.
React 360 is a useful and visually-appealing VR app building platform featuring everything you need to develop stunning VR experiences for PC and mobile web. This platform is the result of efforts from the React team, Google, Facebook, Microsoft, among others.
PropTypes is a nifty little package that makes it easier to manage prop validation for React components. PropTypes is a static type checker for JS properties. The ultimate goal is to give your application the same level of feedback as Flow or TypeScript.
Angular CLI is the command-line interface for Angular applications. Angular CLI provides application development lifecycle management build time tooling and a local development server.
Angular CLI (Command Line Interface) is the quickest way to start new Angular applications. It can serve as the foundation of your hybrid or mobile app by creating a solid starting point with minimal effort. It also allows you to create the scaffolding of your server-side rendered Angular application.
It is used for creating Angular applications, components, services, and other related files. Angular CLI can be installed on your local machine or within a NodeJS based project.
Angular Elements makes it easy to package Angular apps as reusable UI components that can be published to NPM, JSPM or CDNs. The core idea is that an Angular application can be divided into independent and reusable pieces called elements. These elements can then be packaged into a custom element module format and be reused in other applications.
It mixes and matches UI components from different Angular applications with a few lines of HTML and builds your application faster!
Augury is a highly extensible and easy to use plugin for AngularJS that generates visual dependency, component or route diagrams.
Augury is a debugging tool that can show component trees, allow you to inspect their properties, events, and even patch methods on the fly – all in a browser without leaving your page!
It helps you to discover and monitor data flowing in and out of your application. It is different from the console. Instead, Augury shows you much more than that—it shows you how your data changes over time.
Compodoc is a new open-source tool that allows you to easily add a docs directory to your Github repository. With Compodoc, you'll be able to host user manuals or developer guides for your projects without any setup on your user’s end. This means that by simply pointing the browser to a URL like http://compodoc.net/my-project , anyone will be able to read documentation right in their browser.
Ngx-admin is an Angular admin dashboard template with a collection of custom inputs, directives, and behaviours. It is focused on developing faster, easier, and a professional UI Kit for developers to create their admin panel or dashboard project.
It's built on top of Angular UI, Bootstrap 3 and Ionicons. You can use either jQuery or AngularJS for Ngx-admin development.
The smaller the bundle size the quicker the application is likely to load. Angular eliminates much of the bloating by not including the framework in the final app. It doesn’t include any development utilities and deletes any unused modules. This minification of applications makes them load faster.
In comparison, React uses the Webpack to split the code into multiple smaller chunks of code and imports it dynamically to reduce the overall bundle size. By dynamically importing the code, the application only loads that code that is necessary for the execution of a particular task.
React is fully backwards compatible. Developers can easily add different releases of libraries into older applications. For developers who are used to developing apps step by step, React may be the best possible choice as Angular doesn’t support backwards compatibility. You cannot directly jump from version 2 to version 9 and will have to install all the updates between the versions.
Both angular and React are great tools to develop web applications. Both of them have tons of advantages, but React does the job a bit better than Angular. It loads applications fast and is much easier to work with as compared to angular. React is preferred by many developers primarily because of its virtual DOM that is far better than Angular’s DOM.
Through React, you can debug your apps in isolation that is great for maintaining application stability. Furthermore, React is also component-based, and you can reuse those components to save time and costs.
It is also very easy to migrate between different versions of React as compared to Angular as you don’t have to install updates separately one at a time. In short, React speeds up development times because of myriad of tools that offer flexibility to the developers.
