Are you starting a new app development project and couldn't decide which framework to use for the project? Well, you are not alone. The majority of developers, freelancers, and even experienced programmers find it very difficult each time they start a new project. If you are confused between React vs Angular Frameworks, this post is for you.
If you think that you will get an answer to your dilemma of whether to choose to React or Angular for your project, this post does not do that. It is not possible to give a black or white answer to this question. What I have done is I have compared both the frameworks to give a clear idea as to which framework is suitable for your project. Believe me, by the end of the article, you will be able to decide which framework is best suitable for your current project.
Before we start the comparison between React and Angular, let's discuss both of these frameworks in brief.
Angular is written in typescript and has been one of the most used frameworks for single-page applications. Angular without “JS” refers to Angular 2 and the above versions. Whereas AngularJS refers to Angular 1.x versions. The latest version of Angular is 10, released on June 24, 2020. However, Google still supports AngularJS. Some of the applications were built with Angular Upwork, Google, Nike, and Forbes.
Technology Features: Angular vs ReactJS
As far as Angular vs React is concerned, there are significant differences between both the technologies, but comparing their features would not be fair. Having said that, Angular is a full-blown, feature-rich framework while React is a UI component library. It allows devs to figure out how their app will look and also used for building native-rendered web apps as well as mobile apps.
On the other side, Angular offers a full-fledged toolkit that consists of everything needed to develop large-scale apps. So, let us check out the exclusive features of Angular and React individually;
Dependency Injection (DI): Used in the design for enhancing efficiency and modularity of Angular applications;
Templates: Angular HTML templates represent a view of an Angular application;
Components: It defines a class containing application data and logic and works as a building block to control HTML views to be displayed in the targeted environment.
Routing, provided by @angular/router: Offers a service to define a navigation path among the various states and view hierarchies in your app.
@angular/forms for building forms: Allow applications to handle user input data in two different approaches: reactive and template-driven;
Component CSS encapsulation: To encapsulate component CSS styles into a component’s view without affecting the rest of the application;
XSS protection: The Cross-site scripting attacks inject malicious code into web pages and steal the user data. Angular’s XSS protection automatically escapes values and prevents XSS vulnerabilities on the server.
Code splitting and lazy loading: In complex web apps, large JS files delay app interactivity. Code Splitting allows you to divide such files without compromising app features. Whereas a design pattern, lazy loading keeps initial bundle sizes smaller that helps decrease load times.
Test runner, framework, and utilities for unit-testing: Angular offers a lot of efficient tools for testing Angular applications.
State management using setState and hooks: State is an object that can store and manage multiple properties of components. The setState() method is used to update the State object in response to event handlers, prop changes, or server responses. Hooks allow you to use the state object without writing a class.
XSS protection: Everything is converted into a string before being delivered that helps prevent cross-site scripting-XSS attacks.
Code-Splitting and Lazy Load: React apps have their files merged into a bundle using Webpack, Rollup, or Browserify like tools. When the app scales up, the bundle will grow, too, so you can use the code-splitting feature supported by bundler tools.
It splits your bundle into multiple that can be dynamically loaded at runtime. The practice enables lazy-loading things needed by users on runtime and improves overall performance without reducing code amount.
Error handling boundaries: Such boundaries are React components that catch JS errors during rendering, in lifecycle methods, and constructors of the whole component tree below them.
Utilities for unit-testing components: React open-source ecosystem offers a few tools and libraries to test React applications.
After an overview of popular features for React vs Angular, now, let's dive into the advantages of React and Angular in a specific manner.
Superior user experience
When it comes to user experience, React uses Virtual DOM, which is the abstract of the real DOM. It makes it very easy for developers to incorporate and update changes made by the users in the application without disturbing other parts of the app interface. It offers an excellent user experience due to a very dynamic UI.
With React development, the components are completely isolated. Developers can use code components at any given time, making it easy for developers to make any updates or changes. Here, changes made in one will not affect others. It makes the whole app development process quicker, more comfortable, and efficient too.
One of React’s most alluring characteristics is that developers can use existing code again, and it makes development fast and quick. Not just that, it also improves overall app performance.
Testing is quick and efficient
If you are using React, the testing will be as smooth sailing as you don't need to store and manage large-sized component states with dynamic elements. Hence, when you test the app, you don't need to involve child components as you can add an application state in each component of the single object. In the end, the testing of the app is simple, flawless, and quicker.
Benefits of Angular front end development framework
Clear, cleaner, and conscious code
Angular mobile applications perform better than other frameworks as it has a hierarchical dependency injection that ensures that classes are not dependent on each other. It improves the performance of the app to a great extent by turning classes to external sources.
A material design like interface
One of the most useful angular development qualities is that it has prebuilt material design components for almost every element, such as navigation, form controls, layouts, pop-ups, and data tables. It improves the interface of the product and makes it more user-friendly and scalable.
Better error handling
Also, one of the most critical aspects of Angular is that it has a better error handling process, such as an upgraded error handling process for output.
The Main Comparison between Angular and React
Before you can go more confused between React and Angular, let's discuss various parameters to find the difference between Angular and react by comparing both the frameworks.
If we have to believe Google search results, React has been searched more than Angular. However, Angular has its popularity that is increasing with each passing day due to the superior performance and security it offers to the applications. When it comes to popularity, both the frameworks win here.
If you want to make an app with Angular, you need to be a master of the craft. You not only have to learn just AngularJS, but also other programming languages, concepts, templates, pipes, dependency injection, and other crucial elements and concepts such as Typescript. In addition to that, it also has a complicated and complex component management system. Another fact is that the framework is continuously evolving with time, and developers have to check updates in the new version continually and hone their skills and expertise accordingly.
Development Speed and Productivity
Developers love to develop apps with Angular, thanks to the CLI, that allows developers to create components and services with one command line and make it easy for them to develop applications effortlessly. In addition to that, Typescript allows no coding issues and provides error-free and clean coding.
Unfortunately, it is not the case with React. Due to the presence of third-party libraries, speed and performance are affected hugely. Also, the toolkit for React will change from project to project, and when handover within the organization happens, it might create issues.
In the comparison for speed and performance between React Vs Angular, Angular wins.
When you start a new app development project, you must have the freedom and flexibility to choose the tools, libraries, and other aspects such as architecture. React allows such freedom to the developers. It is not the case with angular as it offers a limited amount of flexibility to the developers to choose from. Even the latest Angular 7 version does not allow you to use components other than Angular.
Document Object Model
One of the drawbacks of Angular is that it uses real DOM in which a single change or update on the version will change the whole tree data structure. On the other hand, virtual DOM allows developers to change a particular part of the app version without disturbing other parts of the tree.
The ionic framework offered by Angular has a Cordova container that does not provide a native UI experience to the users as it makes users feel a browser-type feeling.
When to Choose to React?
Your project needs a specific, customized app solution.
If your development process involves components with different and variable states, such as active/inactive navigation items, user login, as well as access permissions, dynamic inputs, enabled/disabled buttons, etc.
When to Choose Angular?
When you are well-versed with Java, C#, and former versions of Angular.
Your app complexity extends from Low to Medium level.
You like to embrace ready-to-use solutions and require higher productivity.
If your app requires to regulate the app size, as performance budgets in Angular CLI monitor and ensure parts of your application don’t exceed the pre-decided boundaries.
You are required to develop a large-scale and feature-rich application.
