Let’s plunge into the fundamentals of Blazor and Angular to gain valuable insights and decide which frameworks work great for your business.

What is Angular Framework?

Angular is one of the well-liked JavaScript frameworks which is developed by the popular technology company Google. Whether to develop a dynamic and complex web app or large applications, angular proves to be a powerful framework. 

  • Developed by: Google 
  • Development Year: 2010 
  • Programming language: TypeScript

What is the Blazor Framework?

Blazor is a contemporary open-source web framework developed by Microsoft that is used to develop interactive and robust web apps with rich UIs. These web apps built with Blazor WebAssembly and Blazor Server can offer great performance and flexibility, running seamlessly on either the client-side or the server-side depending on the hosting model used and the application’s requirements.

  • Developed by: Microsoft 
  • Development Year: 2018 
  • Programming language: C#, Razor syntax, HTML, and CSS

The name Blazor suggests a combination of browser and Razor. It consists of three development options:

S.NoBlazor TypesDescription
 1.Blazor PWA It helps to build progressive web apps. 
 2.Blazor Native It can be leveraged to build native apps for various mobile platforms. 
 3.Blazor Hybrid It can be utilized to create hybrid apps. 

Features of Blazor vs Angular

Both frameworks offer some of the intuitive features that make them come in the list of popular frameworks. Here are the incredible features of Blazor vs Angular: 

Blazor Features: 

  • Build interactive web UI utilizing a programming language such as C#. 
  • Blazor WebAssembly is still in the process of adding PWA support, while Blazor Server doesn’t support PWA development.
  • Blazor allows the building of reusable C# components.  
  • Developers can easily test the applications with fully enabled server-side debugging.  
  • Blazor Server provides server-side rendering, but Blazor WebAssembly does not.
  • Lazy loading which can overall improvise the speed of an application. 

Angular Features: 

  • Create PWA with angular to provide an app-like experience to the users.  
  • Angular keeps improvising its Component development kit. CDK provides quick refreshing and virtual scrolling.  
  • Easily create customized HTML tags with widgets.  
  • Angular CLI (command line interface) helps developers to explore readymade features in a seamless way. 
  • No need to write individual links on MVC layers.

Pros and Cons of Blazor vs Angular

These frameworks have their own Pros and Cons. Let’s explore them.

Blazor Pros and Cons

Blazor Pros 

  1. Simplified development 

While using the Blazor framework, the developers do not need to learn JavaScript or any specific web-based technology. It can enable developers to leverage C# and .NET to create immersive web applications, along with making the development process simple and easy. 

  1. Server-side rendering 

The Blazor framework has the capability to support server-side rendering. It can foster improved performance along with a quick loading time. This feature is extremely helpful in the case of large applications which need sustainable client-side processing power. 

  1. Cross-platform support 

Thanks to Blazor cross-platform development support, help in creating immersive web apps that can seamlessly work for different devices and operating systems.  

  1. Reusable components 

It has a component-based architecture that facilitates developers to utilize reusable components. This, in turn, can minimize the code written time and make the development process much faster.

Blazor Cons 

  1. Reduce scalability 

It creates problems in handling client connections which happen on the server side utilizing SignalR. Hence it requires some extra effort to expand the application. 

  1. Performance 

When client-side rendering is compared with server-side rendering, the client-side rendering is not as fast as the server-side in some kinds of applications. 

  1. Limited libraries and tools 

Being the newer framework, Blazor has limited libraries and tools compared to react or angular frameworks. Therefore, it becomes a tedious task to get the solutions for a dedicated problem.

Angular Pros and Cons

Angular Pros 

  1. Component-based architecture 

Angular is a popular framework that leverages component-based architecture allowing developers to create complex web UIs for large applications with reusable UI components.  

  1. Two-way data binding 

Due to this, Angular can allow seamless data flow between the data model and its components, which eases the development process. 

  1. Dependency injection 

It has a robust dependency injection system that helps to handle the dependency between the components and services effectively. 

  1. Testing support 

It has built-in testing support that helps developers quickly run the test to ensure the web application is bug-free.  

  1. Large ecosystem 

It has a huge set of resources, libraries, and tools that can help developers create immersive web apps along with seamless third-party integration.

Angular Cons 

  1. Steep learning curve 

It’s not easy to learn the Angular framework, especially for beginners, as it is a complex framework.  

  1. Performance issues 

It is loaded with many features and functionalities which can give performance issues. Let’s say the two-way binding feature can slow down the application due to its resource intensive.  

  1. Large file sizes 

As angular has large size of files and it can slow down the loading time and increase the bandwidth as several third-party libraries utilize it for application. 

  1. Limited SEO capabilities 

It is wonderful when it comes to developing single-page web applications. But when creating a complex app, it becomes difficult for crawlers to crawl the web content. It can be a good solution for server-side rendering, but one has to go the extra mile to fully leverage the capabilities of SEO with Angular.

Blazor vs Angular: Head-To-Head Comparison

Here are some of the head-to-head comparisons between Blazor WebAssembly and Angular: 

ParametersBlazor WebAssemblyAngular
Developed by Microsoft Google 
License Apache MIT 
Code reusability  High High 
Programming language C# TypeScript  
Rendering Client-sideClient-side
DOM Incremental Regular 
SEO compatibility SEO-friendly limited

GitHub stars 9K 143K 
Documentation Detailed Detailed 
Performance Microsoft making continual efforts to tune for performance. More tuned as it is a mature framework. 

Blazor WebAssembly and Angular are both client-side frameworks used to develop web applications. Blazor WebAssembly allows developers to build applications using C# and .NET in the client’s browser. It offers high code reusability and fast UI updates thanks to its incremental DOM rendering. Although it has limited SEO compatibility and PWA support is still being developed, it has a growing ecosystem and extensive support for .NET libraries.

Angular, on the other hand, is a mature framework that uses TypeScript to build web applications. It supports both SPA and PWA and has a vast library of resources. However, its learning curve can be steep, and its regular DOM rendering can result in slower UI updates. Overall, developers can choose between these frameworks based on their needs and preferences.
