An overview of Angular

Angular is an open-source JavaScript-based framework that simplifies the process of building web apps.

With Angular, it is easy to create scalable apps due to its MVC–model view controller design pattern. Again, developers can separate the app components for easy development, testing, and maintaining a web app.

Many businesses prefer Angular because it comes with a ready-to-use framework that supports MVVM/MVC apps. Again, the faster loading speed algorithm of Angular makes it supreme when compared with Blazor.

Today, most developers will choose Angular because of the dynamic features that make the whole app development process seamless, the wide community support, and the ease of use. Again, these are the latest Angular versions with meaningful changes and improvements that make the whole development field easier. Therefore, as you propose to use Angular, always consider the latest version for better results.

Angular features

angular and blazor

The following Angular features will help you understand the difference between Angular and Blazor.

  • MVC Architecture

The MVC pattern in Angular enables developers to separate the app components into three: the model for data, the UI for view, and the controller for managing interactions between the view and the model.

  • Two-Way Data Binding

In Angular, there is no manual DOM manipulation. The two-way data binding harmonized data between the view and the model automatically. The captured changes are then reflected on the respective side automatically.

  • Modular Architecture

The modular architecture helps developers divide the bigger application into sub-components that can be reused. These small components are called modules. The module architecture makes it easy to reuse, organize, and maintain the code.

  • Directives

Angular uses HTML attribute directives or components with HTML functionality. This helps developers customize behavior patterns, manipulate the DOM, and bind data.

  • Extensibility

Angular, being a wide framework, has a solid ecosystem with many extensions, third-party integrations, and libraries. All these extensions enhance the Angular functionality and make the whole add development process seamless.

  • Dependency Injection

Dependency injection in Angular means the framework supports code reusability and modularity. This helps developers speed up the development process while cutting down on costs.

Benefits of Angular

So, why would a developer choose Angular and not Blazor? Below are some of the top benefits that make Angular stand out as the best framework.

  • Ease of use and improved productivity

Angular is among the flexible frameworks. Any developer can use it. Angular and customize the processes to align with the project’s requirements. What’s more, it is easy to use Angular compared with other frameworks. The ease of use and customization enriches developers with experience, thus enhancing productivity in all aspects of app development.

  • Better code management

Angular uses TypeScript, which enhances code maintainability and code management. What’s more, developers can easily scale the app with Angular because TypeScript code is more accurate, easy to predict, and quite clearer. This gives the developer the ultimate confidence in every step they take in the app development process.

Any developer looking for reliable information and resources in relation to Angular can find it on the Angular platform. Since the establishment of Angular, there has been an active platform with professional angular developers and engineers ready to answer and discuss any Angular queries. This makes it easy for an established developer to find immediate answers when looking for something. Upcoming developers can also get useful insights and tips as they learn and master Angular.

Disadvantages of Angular

Does Angular have any disadvantages? Sure. As much as it is a framework that does much in the app development field, it also has some disadvantages, as highlighted below:

  • Limited SEO

While Angular is perfect for creating solid SPAs, SEO limitations come in because SPA apps are rendered on the client side. Therefore, it becomes hard for web crawlers and search engines to review the relevant content and structures for such pages. In the end, it becomes impossible to list a website in the search engines for ranking. However, with the right tools and resources, the developers can put in extra effort and use Angular Universal to address SEO limitations in Angular apps.

  • Steep learning curve

Well, Angular is written in TypeScript. Therefore, it becomes hard for JavaScript programmers to learn and master Angular faster and more easily. The wide range of topics, including dependency injection and RxJS, requires developers to commit more time to them. However, the good part is that the same Angular has a wide supportive community to assist upcoming developers who want to learn and master Angular faster. Again, the supportive community makes it easy to find the best Angular developers for your next project.

  • Too many versions

As mentioned before, Angular has been releasing different versions since its inception. While it is advantageous in some ways, especially for expert developers, it is also tough for beginner developers.

Take this example: when a beginner has just finished learning and mastering one version, the release of another version is already up. It becomes hard for a developer who is just starting, especially when working on a new project. Therefore, the many versions suit expert developers since they have adequate knowledge and skills of how to integrate the latest versions in the ongoing project, contrary to beginner developers.

  • Lack of enough details in CLI documentation

Several developers have raised a major concern about CLI documentation. Even though it is quite useful in one way or another, the information isn’t detailed, forcing a developer to spend some more time researching answers to specific contexts.

  • Security concerns

Angular, being a front-end framework, depends heavily on the client side for data handling and rendering. Therefore, if no proper security measures are put in place, the app becomes vulnerable to threats like cross-site scripting. It is, therefore, the role of the developer to take extra precautions to ensure all security concerns are addressed.

When should you use Angular?

Finally, you are wondering when you need to use Angular and not Blazor. Check below

Use Angular when:

  • You are building complex web apps that are large-scale with solid community support
  • You want a client-side rendering for flexible user interfaces
  • Looking for a set of pre-built components and tools that ease front-end development

An Overview of Blazor

Developed by Microsoft, Blazor is an ASP.NET framework used in web apps for C# code. Blazor apps are created on CSS and HTML web technologies. However, instead of using JavaScript, the Blazor framework allows developers to use Razor and C#, which is a common template in the framework, hence the name Blazor.

When compared with Angular to some extent, Blazor outweighs Angular capabilities because developers can use it both on the client side and server side of web apps. The client-side app is effected through WebAssembly, while the server-side Blazor app is effected as HTML in the browser, making work easy for developers.

A developer with C# skills can use Blazor to create highly responsive and flexible web apps.

Again, since Blazor works perfectly with .NET libraries and frameworks, developers can easily reuse the code and create an extensive .NET ecosystem.

Features of Blazor

blazor vs angular

Among the features that make Razor to be unique in its way include the following:

  • Razor Syntax

Blazor utilizes Razor syntax, which is a combination of HTML and C# technologies. This syntax enables developers to readable and expressive code for interactive and dynamic user interfaces and

  • Event Handling

Blazo framework is powered with solid event-handling practices, which enables developers to trigger actions and manage user interactions. A developer can use C# when handling events or wire the events in the Blazor’s component markup.

  • Component-Based Architecture

Blazor uses component-based architecture, which assists developers in creating reusable UI elements.

  • Integration with .NET Ecosystem

Blazor framework works perfectly with the .NET ecosystem, which allows developers to explore already existing tools, frameworks, and libraries. This approach enhances code sharing and increases productivity.

  •  Routing

The routing system within Blazor enhances easy navigation in a Blazor app. A developer can easily explore routes, map the routes to components, and manage navigation for a responsive and seamless user experience.

  • Security

Blazor comes packed with in-built security components that protect Blazor apps from web threats. It combines with authorization and authentication systems to guarantee secure access to the Blazor app’s resources.

Advantages of Blazor

So, what makes Blazor a perfect framework? Below are some of the top reasons why a developer would prefer Blazor over Angular:

  • Offline availability

A user doesn’t have to be online throughout to use the Blazor’s app. Once they download the app, they can comfortably access the app while offline without experiencing performance and speed issues.

  • Cross-platform compatibility

With Blazor, a developer can create apps that run perfectly on varied platforms such as web browsers, mobile phones, and even desktops, among others.

  • Less complex

Unlike Angular, the Blazor framework doesn’t require complex tooling for front-end development. Developers, therefore, find it easy to write and maintain the code, thus enhancing its accuracy level.

  • Improved performance

Blazor runs on the client side; thus, there is no need for communication with the server. This creates a seamless user experience, and the page loading speed is faster, creating a highly interactive environment.

Disadvantages of Blazor

So, what could make one opt for Angular and not Blazor? Below are some notable disadvantages of Blazor

  • No offline support on the Blazor serve

The Blazor’s server must stay active throughout. The app, therefore, can fail to function when the internet connection is poor.

  • Must use ASP .NET Core

Blazor relies heavily on the ASP.NET Core server for smooth running. This means you must have ASP.NET Core to create any Blazor app. This limitation is what makes some developers opt for other frameworks.

  • Browser restrictions

Not all browsers support Web Assembly. This creates a limitation of the browser’s capabilities since Blazor can only work on browsers that support Web Assembly. Internet Explorer, for instance, won’t work well with Blazor.

  • Application weight

The performance of Blazor’s app can be affected heavily depending on the weight of the app.

When should you use Blazor?

Use Blazor when:

  • The project has a tight deadline
  • If you have C# skills and want to create an app faster

Blazor vs. Angular Difference

Having described both Angular and Blazor, below is a detailed comparison between the two powerful frameworks.

  • Language used

The angular framework uses TypeScript, which is a superset of JavaScript. It is a commonly used language when building server-side applications. It also enables front-end developers to use CSS, HTML, and TypeScript together to build apps. With TypeScript, developers can create progressive web apps, interactive UIs, and single-page applications.

Blazor, on the other hand, uses C# to build both client-side and server-side codes. Developers, therefore, can use one language to write code for the server and client sides. The Razor syntax helps developers create interactive and reusable user interfaces using web technologies like HTML and C#.

  • Community and support

Any web developer using Angular or Blazor framework can get support from the respective platform of the specific framework. This can be in the form of forums, blogs, documentation, guides, and tutorials.

Angular has a wide, supportive community with a large team of professional developers and engineers. It is, therefore, easy to get relevant questions about using Angular in app development.

Blazor, on the other hand, is relatively new, and the community is still growing. Nonetheless, you can always get those Blazor basics from the available community.

Therefore, on matters of community and support, Angular outweighs Blazor.

  • Performance

Angular has a steady performance compared to Blazor. The AOT compilation mechanism in Angular enhances the loading time of Angular apps and highly responsive apps, thus top-notch performance.

Blazor’s client side, on the other hand, has a slower loading time due to the Web Assembly file sizes. The Blazor’s server side, however, has a steady loading time but can still face interaction latency because of server round trips.

Again, in terms of performance, Angular takes the lead.

  • Coding Time

When compared with Angular, creating and troubleshooting code is faster in Blazor. Of course, the turnaround and troubleshooting are faster in Blazor and not in Angular. Therefore, on matters of coding time, Blazor takes the lead.

  • Architecture

Both Angular and Blazor follow component-based architecture. However, Angular uses components as building blocks of an app, while Blazor uses reusable components to build UI. Again, Blazor supports both the server-side and client-side of an app, contrary to Angular.

  • Ease of Learning

Angular is quite complex. While it has a wide community offering extensive support, there is a lot a developer has to learn to master Angular. Besides, the many versions make the learning curve become a bit complex. It requires time and dedication.

Blazor, on the other hand, doesn’t require much. With .NET and C# skills, you are good to go. However, you may need to learn and master some aspects of using Web Assembly for Blazor apps.

  • Security concerns

Both Angular and Blazor take security matters with strong approaches. Both frameworks have built-in security measures to protect the applications against possible vulnerabilities and threats.

Angular vs Blazor: which one should you choose?

From this blog, it is evident that both Angular and Blazor are solid frameworks that play key roles in shaping the app development industry. Again, they both play a big role in streamlining the front-end web development processes.

As a developer, depending on the nature and dynamics of the project you are handling, you can choose either Blazor or Angular. The goal is to have a seamless development process with faster and more accurate results.


As the app and web development industries continue to grow, new tools and resources keep growing. Blazor and Angular frameworks, for instance, help developers simplify complex processes into simple, manageable tasks.
