    Study Notes

    Web Development Frameworks

    • The primary purpose of a web development framework is to provide a structured approach to building web applications.

    Types of Frameworks

    • Frameworks that focus on user-facing elements of a web application are typically referred to as front-end frameworks.
    • Open Source web frameworks offer the benefit of being free and community-driven, allowing for faster development and lower costs.

    Blazor.NET

    • Blazor.NET primarily focuses on building web applications using C# and the .NET runtime, allowing for a full-stack development experience.

    WebAssembly

    • WebAssembly is used to enable web browsers to run code in web applications, providing better performance and security.
    • The main purpose of utilizing WebAssembly in web development is to enable fast and secure execution of code in web browsers.

    Blazor WebAssembly

    • Blazor WebAssembly updates the DOM by using a virtual DOM, which reduces the number of DOM mutations and improves performance.
    • A major disadvantage of Blazor WebAssembly applications is that they can be large in size, which can impact initial load times.
    • Blazor WebAssembly runs within a web browser instead of a server because it uses WebAssembly to execute .NET code directly in the browser.
    • Blazor WebAssembly enables faster screen updates compared to traditional server-side frameworks because it can update the UI directly without requiring a round trip to the server.
    • JavaScript interop is used in Blazor WebAssembly to enable communication between .NET code and JavaScript code in the browser.

    Blazor Hosting Models

    • Blazor runs client-side in the browser on a WebAssembly-based .NET runtime in the WebAssembly hosting model.
    • Blazor Server uses SignalR to communicate between the client and the server, enabling real-time updates and two-way communication.
    • The primary function of SignalR in a Blazor Server application is to enable real-time communication between the client and the server.
    • Blazor Server uses WebSockets as its default transport protocol for communication.
    • The WebAssembly hosting model generates HTML on the client-side, while the Server hosting model generates HTML on a web server as it is requested by web site visitors.
    • The primary difference between Blazor WebAssembly and Blazor Server hosting models is where the .NET code is executed: in the browser or on the server.
