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.
