Running Blazor in Production, Lessons Learned 

I already created a web application in Blazor, the best things, it works perfectly!!! and in production!!!

I'd take Blazor over any JS/TS/npm tech any time of day. It's so much easier to just use C# across the whole stack. I have backends in production, written in Java, communicating with Blazor Server apps through SignalR and it works like a charm.

I already use Blazor WASM to develop e-commerce application. Thanks for the exciting book about Blazor!

Mr. Jimmy. Thanks a million for thos beautiful useful introduction. I bought your brilliant book, it's amazing from zero to hero. Actually Blazor was my dream as a full stack developer using C#. All my new projects are on Blazor and working perfectly.

I'm working with Blazor, and I love it

Thanks a lot Mr. Jimmy for this awesome video, I really like the way you explain Blazor

We also use blazor wasm in our projects as mercantile exchange company. Thank you for sharing your knowledge.

My first computer was a ZX Spectrum 48K+, also did the coding loop. The fact you got a command prompt and could start coding when you switched it on was great...

Blazor is great!

im breaking into serious development and i am focused on maui with blazor hybrid.

I Just discovered this channel!!! I love your passion! I wish I was working with such a team! Maybe Blazor will save my dev career... I mean put me back on track!

At 9:25 when he started to explain the flow between the browser dom and the backend, I decided to keep watching. Explained very well.

För övrigt bra presentation! Täcker de mesta man skulle vilja veta. Visste inte att de var så stort bland större företag, har själv kört det i lite olika bolag som jag konsultat hos men de är inga top 10 ställen.

You’ve really explained well everything around Blazor. ❤

Love Blazor! Have a couple small sites running it, and also have production code at work. Server side, WASM, and looking forward to the hybrid model in .Net 8! I didn't mind vanilla JS but never wanted to learn a framework. Looked at Xamarin but never did WinForms and then Blazor saved my life!

I am learning Blazor now; well, that and C# and bootstrap at the same time.

I am really happy to hear that because today I work with PHP and React, and this is a daily pain for refactoring or adding features. I beleived strongly in Blazor since the beginning because the coding strucure is awesome and clean. I hope that more and coders and companies will move on Blazor since this a really game changer to my opinion.

Maybe it is time to start using Blazor for upcoming projects. Give it a try.

I recently started working with Blazor but I've been loving every second of it. For an old webforms dev it comes really naturally. I'm trying to do it with WASM from day one though.

Really cool stuff, very well explained

"Its not Highlander" - lol, perfect :)

I am currently designing and developing a application as a contractor that is Blazor WASM for the UI.

Regarding code behind. I usually start off with c# in razor pages when they might be a small component or whatever. If its a huge baseclass with lots of dependencies and methods I have it as codebehind and move it under another file structure just to make it easier to work with since those razor pages usually have a lot of code inside them anyways.

Blazor is so much cleaner then JS solutions and it's getting better all the time. Right now the thing that it needs the most is better interop with JavaScript. it would be really great if there was a way to interface with JavaScript API calls with little to no JavaScript. I hate working with JavaScript async, returning multiple values and having to serialize and deserialize data when it doesn't work.

No one is talking about this but the problem with blazor wasm is not the download size but the loading time esp on phones. prerendering solves the problem halfway as even with the page fully loaded, it remains unresponsive untill the wasm loads. during the loading time the user can neither navigate to a diferent page not click on any button

Is there a Contoso complete Example ?

Hi, could your viewers get a link to the source code?

The only caveat I see, it is the need of an extra runtime layer in the browser, in case of Blazor Webassembly, because blazor does not create a webassembly executable(binary) directly, I think it is dotnet which does it, I think Blazor Server Side could be more approachable to Csharp Devs in this regard, I don't know if in the new AOT compilation probably blazor creates webassembly binaries directly, probably a good question to ask you, and another is what version of Blazor tastes would you prefer, WebAssembly, or Server Side Rendering taste??

34:52 YES 1000 times, i have seen alot more performance by using html+css is unreal, syncfusion, telerik, radzen all crap, pure html and css is your friend to actually save performance and time when you need to customize, Build your reusable components

Here goes one of my subs

Great stuff man. However, the memory consumption is not just due to F5. Blazor just keeps adding up the memory on every page navigation, but not releasing the memory that was consumed before. When hundreds of people use the website and move around different pages, blazor is ballooned up with huge memory and eventually goes out of memory. Any suggestion??

Hi Jimmy, how do you deal with storing app-wide/persisted state in your production apps? Are you injecting your own statecontainer service or are you using any of the libs out there such as fluxor or blazor-state?

What blazor needs is a way to directly access browser / dom using c# and just bypass JavaScript. Blazor still clunky when it comes to working with dom. Also, they need a better way to create and work with API’s. They need something like like EF that will just create all the API for you.

Wait isn't the whole component updated when it changes? Not just the h1 with Rulez -> Rules?

What do you mean with adding a refresh button? Would you please explain (or show some code) of how to implement a refresh button.

the angular killer? lol way to set the bar high

Hello Young. I have a system developed entirely in Blazor and Oracle. The detail is that it hangs from time to time and I have to restart the server. You say that blazor supports millions of users, I don't have 50 concurrent users and it crashes. What should it be?

The problem with Blazor is that it is inherently inefficient. Either you have to have a persistent connection to the server, with associated latency. Or you have to download 1 mb of WASM data. It is just less efficient to translate between C# and JS than just running directly in JS. Now, that may be alright in many cases, but you have to be aware that you'll never be able to match Angular or React for download size. Now, .NET 8 may change with the ability to do server side rendering and sprinkle WASM where needed.

on the one hand Blazor is amazing, I can imagine things like: photoshop, protools, videogames, a ZX Spectrum emulator, etc. running in the browser, which is mind blowing. However in the other hand I understand the perspective of the person who told you: "never gonna be a thing"... because You can not generalize all web projects into a single way of working. I understand the power of Blazor for large projects BUT in light projects, the programmers like to be in control (including me), and not that there's a lot of "MAGIC" everywhere, because that implies that many things are going to happen behind the scenes, things that I don't see and can't debug, and that at some point are going to go wrong... Microsoft should have already learned that after the slow death of the web forms. I don't think the solution is to remove javascript or say you don't need it anymore... It's like to do a simple task (like a table CRUD) you need a spoon but Blazor is like carrying a big bulldozer... you don't need THAT much power for something so simple . I think that's what people at Microsoft can't see.

哈哈哈👍

M$ products often is no capable of killing other tools, but itself. History proves it.

It really does feel like cheating.

async void is blasphemy in dotnet world lol

47:29 “…Blazor has to be able to handle millions of users…but it can’t!” Everyone developing a website/app hopes to reach as many people as possible, not being able to handle huge amounts of users is not a good sales pitch! So basically, if expect to one day reach millions of users you’ll need to switch to a MEAN OR MERN stack, so you may just as well use either JS stacks from the get go?

Waay too much time on something other than production. U forgot ur target audience

I dont think anything can kill javacript ecossytem in the frontend environment.
