.Net 8 and Blazor Render Modes Changes


With the release of .Net 8, Blazor got some great updates. Blzoar is now a full-featured development system.  With the latest Blazor, you can build websites, web applications, desktop applications, Progressive Web Applications, tablet applications, and even mobile applications.  That is a long list of things you can build with Blazor and C#.


Render Modes

.Net 8 has added new render mores and has made great improvements to the old render modes.  These changes have really pushed Blazor to new heights of building great applications.

The old render modes are server and web assembly.  

Server mode 

This mode would use SingleR to open web sockets to the server.  In this mode, everything is compiled on the server and sends just the changes to the client.  It allows you to isolate your code to the server and keep your code secure.  The downside is that it can get expensive to scale to handle a large amount of users.


Web Assembly

This mode allows everything to be executed on the client. On the bright side, you use fewer server resources and can scale infinitely.  The downside is that all your code is downloaded to the client before it can begin to be executed. Also, since the code is on the client, it is not secured.  


New render modes

Not only are the old render methods supported, but there are also three new ones, Server Side Rendering, Streaming, and Hybrid


Server Side Rendering (SSR)

Positive of this render Method:

1. Everything is processed on the server

2. Very quick to load

3. Direct access to server resources

4. Code is secure


The downside of this Render Method:

1. There are no client intersections


This is a great render method to use when building static websites.  Adds very little overhead for static websites.


Streaming Rendering

This render method adds a new way to add user interactivity to Blazor pages and components.  Can code your page or even a component that when using SSR can add user interactions.  

This is great to use if you have a static website with small sections that could require user input such as a feedback form or a contact us form.


Hybrid Render Mode (Auto)

The best new render mode is a hybrid, a mixture of all the render modes.  This allows your application to take advantage of the fast load of server mode but allows you to download application code to the client in the background and then take advantage of processing on the client.  If your web assembly client needs secure code executed you can code it so that the component runs on the server where the code is secure


How to set/change the render mode

Not only can you set the render mode for the entire application, but it allows you to change and set it at the page and even the component level.  This is a powerful change,

You set the render mode with attributes and by injecting the render mode.


Summary

You can tailor your application for performance, security, scalability, and usability with so many render modes.

With this new customization, you need to do more design on how and when to use rendering methods in your applications.

Yes, Blazor Server can scale!

Image
From the very beginning of the release of Blazor Server naysayers have incorrectly stated that Blazor Server can not scale.  They usually state that the limit is 5,000 concurrent users. There are several misconceptions and wrong assumptions about their statement.  Let's break it down and get a better understanding of Blazor server-side scaling. What is the "limit" for users When Microsoft talks about the need to scale an application, what they are saying is that when a normal response for any concurrent user is taking longer than 200 ms, the system is not performant and needs to scale. We will accept that definition: If any normal user response is taking longer than 200 ms, the system needs to scale for concurrent users. By a normal response, we are referring to a page get, a post, etc.  Large database access requests would not be included in this measurement. What is scaling There are 2 common ways to scale, scale, out horizontally, and scale-up, up vertically. In our di...

Blazor new and improved Search Box

 Back in March, I posted a new Blazor data grid with a search box ( see post ).  Since then I have found a new and improved search box that I wanted to implement.  The search part is implemented the same.  What I added was the ability for the user to narrow down the search by selecting which field they wanted to search on.  This will help the user find what they are looking for and in a large collection, the search will end up being faster. The goal of making the change was to make the search box a new component and have it handle the UI functionality part. Prep Work Here is the prep work I did before adding the search box: Started with the source code from the post listed above. Upgraded the project to .Net 5 Upgraded the Nuget packages that were out of date. Ensured every build and run. Change to a Component I wanted to create a component for the search box so I could use it in other applications.   1. Create a Folder under UIControls called "SearchB...

Blazor - Displaying an Image

I wanted to be able to display an image file within a Blazor page.  During my research I realized that there is very little difference between displaying an image in Blazor as compared to displaying it in a HTML page.  So, I decided to add a couple of other features to my application.   The features I have added are:   1. Get a list of files on the server   2. Display at list in a Blazor page   3. Provide a UI effect to zoom in on the image   I will be using the Blazor Server configuration for this application.  We can do this with the Client-side configuration, but you need an API to access the server files.  I have created a folder under WWWROOT called DsiplayImages where I have placed several images I will be working with.  I have created a service that will access the image files from the server.  In addition, I have created a model for the file properties I a need.   ...
