Angular vs. Blazor: Choosing the Right Framework

Exciting Web Development Duel: Angular vs. Blazor! The choice of proper framework impacts development, performance, and user experience. Join us on a journey to explore two dynamic frameworks, Angular and Blazor.


The front-end framework chosen for a project significantly impacts its development process, performance, and scalability, as well as code maintainability. It streamlines development workflows and contributes to a seamless user experience. In other words, the proper framework is the foundation of a successful digital product.

Today, we will take a closer look at two frameworks – Angular and Blazor. They both provide robust solutions to modern front-end challenges. We will also try to compare Angular and Blazor and their ability to meet specific project requirements and long-term goals.


Angular and Blazor: Short Overview

Angular is an open-source TypeScript-based framework developed and maintained by Google. In general, it is known for its comprehensive features and a structured and scalable approach to creating dynamic web applications. With its Model-View-Controller (MVC) architecture, Angular provides developers with a clear division of labor and encourages modular code.

Blazor is an innovative framework developed by Microsoft that allows developers to create interactive web applications using C# and .NET instead of traditional JavaScript. A unique characteristic of Blazor is its ability to enable both server-side and client-side rendering. All of this combined allows developers to bridge the gap between client-side and server-side rendering.


Comparing Angular and Blazor

We will consider some of the most important points to compare both Angular and Blazor app development.


Development experience

Development experience is one of the key considerations when choosing a front-end framework. It covers various factors, including coding languages, tools, learning curve, etc. Let’s take a look at how Angular and Blazor differ in terms of development experience.


TypeScript brings enhanced code organization, improved tooling support, and better IDE integration. Its static typing allows developers to catch errors during the development phase, reducing runtime issues.

Component-driven architecture
Angular’s development revolves around creating reusable components that encapsulate UI and logic. This modular approach promotes code reusability, simplifies maintenance, and fosters team collaboration.

Dependency injection
Angular’s built-in dependency injection system simplifies the management of components and services. It facilitates better separation of concerns and ensures independent development of different app components.

CLI and tooling
Angular’s Command Line Interface (CLI) streamlines project setup, generation of components, and deployment. The CLI’s robust tooling ecosystem accelerates development, making it easier to focus on building features rather than configuring the environment.

Angular’s learning curve
For developers experienced in TypeScript and the concepts of component-based architectures, Angular’s learning curve is relatively smooth.


Razor syntax and familiar language
Blazor utilizes Razor syntax, a blend of HTML and C#, for defining components and rendering UI. This familiar syntax aids developers in quickly transitioning to Blazor.

Moreover, for developers well-versed in C# and .NET, Blazor provides a comfortable environment that allows them to use their existing knowledge for front-end development. It is built on a common set of languages and tools that are easy to use and stable.

Component-based development
Like Angular, Blazor also embraces a component-based architecture. Components in Blazor are defined using Razor syntax, allowing for the creation of reusable UI elements.

Shared code
Blazor’s server-side and WebAssembly-based client-side options enable developers to share code between the front end and back end, reducing duplication and ensuring consistent logic throughout the application.

Rich tooling and libraries
Microsoft Blazor allows developers to leverage the existing .NET ecosystem of .NET libraries.

Blazor’s learning curve
Developers proficient in C# and .NET will find Blazor’s learning curve pretty smooth, as they can leverage their existing skills. Those new to C# might face a steeper curve, but the framework’s familiarity with Razor syntax can facilitate the transition.

What to choose?

Angular uses TypeScript, a statically typed superset of JavaScript that improves code quality and reduces runtime errors.  

Blazor, on the other hand, extends C# to the front end, providing a cohesive environment for full .NET development. It aims to unify front-end and back-end development using C# and .NET, improving web development workload. Developers moving from .NET may find Blazor’s approach more intuitive, while those familiar with TypeScript may move toward Angular. 

In the case of Blazor, the key advantage may be the choice of Blazor hosting models. It offers different options – Blazor Server, WebAssembly, and Hydrid. Blazor Server benefits from the responsiveness of pages rendered on the server, while Blazor WebAssembly provides a fully client-side experience. The hybrid, in turn, blends desktop and mobile native client frameworks, running Razor components natively on the device. 


Performance and rendering

The way a front-end framework handles rendering and updates can significantly impact the user experience. Let’s take a look at the performance characteristics of both Angular and Blazor and explore how they tackle the challenge of rendering web applications.

Angular’s Rendering and Performance Approach

Two-way data binding
This mechanism facilitates real-time synchronization between the application’s data model and its presentation layer. It automatically updates both the UI and the underlying data model whenever either change.

It allows developers to update the UI without manual DOM manipulation, but this, in turn, can sometimes lead to unnecessary re-renders and performance bottlenecks in complex applications.

Change detection strategy
The Angular framework utilizes change detection to track and propagate changes across the component tree. This strategy ensures that the UI remains in sync with the data model. However, indiscriminate change detection can lead to over-usage of resources and slower performance.

Blazor’s Rendering and Performance Approach

Reactive UI
In contrast, Blazor embraces a reactive UI approach that aims to optimize rendering and updates. It emphasizes updating the DOM only when necessary.

It minimizes DOM manipulations and enhances performance, particularly in applications with frequent updates.

Virtual DOM
Blazor WebAssembly app employs a virtual DOM concept similar to popular JavaScript frameworks like React. Changes are first applied to a virtual representation of the DOM, and then the actual DOM is updated in an optimized manner.

This reduces the number of render tree direct manipulations, which can be resource-intensive. Virtual DOM and asynchronous rendering ensure efficient updates while maintaining a seamless user experience.

Angular’s two-way data binding simplifies coding but requires careful management to avoid performance issues. Overuse of data binding and change detection can result in unnecessary rendering, affecting the application’s responsiveness.

Blazor’s reactive UI and virtual DOM approach contribute to smoother user interactions and faster rendering. It minimizes the performance overhead often associated with dynamic web applications by updating what is necessary only and optimizing DOM manipulation.


What to choose?

When considering performance, it’s important to assess the nature of your application and the frequency of updates. Angular’s two-way data binding can be advantageous for simpler applications with fewer dynamic components. However, in cases where performance is a top priority and the application requires regular updates, Blazor’s reactive UI and virtual DOM can offer a more efficient rendering strategy.
