Server-side pre-rendering for faster initial loading

One of the key differences between Blazer vs Angular lies in their approach to rendering web pages. Wh uses client-sidile Blazore rendering, Angular leverages server-side pre-rendering, which has its own set of advantages. Server-side pre-rendering allows for faster initial loading times, as the server sends a fully rendered HTML page to the browser instead of waiting for the JavaScript files to load and render on the client’s side. This is especially beneficial for users with slower internet connections or devices with limited processing power, ensuring a smooth and efficient browsing experience.

Virtualization for improved performance and scalability

Another notable difference between Blazer vs Angular is their handling of large datasets. With Blazor, all data is loaded onto the client-side, which can result in slower page loading times and decreased performance with larger datasets. On the other hand, Angular utilizes virtualization techniques to efficiently handle large amounts of data by only rendering what is currently visible on the screen. This not only improves performance but also enhances scalability as the application can handle growing datasets without compromising on user experience.

Lazy loading for optimized page loading times

Lazy loading is a technique used to improve page loading times by only loading the necessary components and modules when they are required. This can significantly reduce initial load times and optimize performance, especially for larger applications with multiple pages and components. While Angular has built-in support for lazy loading, Blazor currently does not have this feature but plans to introduce it in future updates.

Communication with gRPC-Web

gRPC-Web, an open-source framework for remote procedure calls, is gaining popularity as a communication protocol between client and server. While Angular has built-in support for gRPC-Web, Blazor currently does not have native support but can be integrated with the help of third-party libraries. This allows developers to leverage the benefits of gRPC-Web in their applications while using either framework.

Razor class libraries for code sharing

Razor class libraries (RCLs) are powerful and flexible reusable components that can be conveniently shared between different projects within the Blazor framework. This remarkable feature enables developers to effortlessly share common functionality and user interface elements across multiple applications, resulting in enhanced code reusability and significant reduction in development time. In contrast, Angular lacks an equivalent feature, making it comparatively more challenging to efficiently share code between projects, thereby impeding productivity and hindering code maintainability.

Full stack testing with Blazor

Blazor’s server-side hosting model and integration with ASP.NET Core enable developers to perform end-to-end testing of both client and server-side components in a single environment. This facilitates comprehensive full-stack testing, allowing developers to test the entire application’s functionality without having to set up separate environments for front-end and back-end testing. In contrast, Angular requires separate setups for front-end and back-end testing, which can be time-consuming and cumbersome.
