getfromjsonasync blazor

Anytime we want to display profile details in any component we can bind to it The rest of your post is really obscurehowever, it seems as though you are the one who should spend some time practicing the asynchronous programming model and Blazor. I recommend setting a reasonable goal for the next release. But, unfortunately I can NOT use the GetJsonAsync() method here, as shown from the GitHub samples MessagePack is temporary solution, once we satisfy with .NET 6, we will move back to JSON. We have the exact same problem. Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. The common methods include: GetFromJsonAsync: Sends an HTTP GET request and parses the JSON response body to create an object. I didn't see much difference (Hardly 1 second) between STJ and MessagePack with HighPerformance power setting. 2022 Moderator Election Q&A Question Collection. If you are using the net5.0 you should look at the System.Net.Http.Json extensions. (Download time on localhost is about 20 ms.). The following GraphExample component uses an injected GraphServiceClient to obtain the user's AAD profile data and display their mobile phone number: This section uses the utility classes (GraphClientExtensions.cs) described earlier in this article. The benchmark containing the same code run on the desktop, shows the following for writing to gltf: It takes nearly 67x as long to run in web assembly. Or are you suggesting I move the app to Blazor 5.0.0 latest preview? Both Newtonsoft and STJ are slow. Also @szalapski on download perf you originally said: but with your latest test from StackFlow you said: It indeed takes 7-12 seconds to return 17000 items (about 1.6 MB) of WeatherForecast. Nothing significant on the CPU, this is my only focus when I am doing this. The following class and configuration are used in each of the following subsections of this article: After adding the Microsoft Graph API scopes in the AAD area of the Azure portal, provide the required scopes to the app's configured handler for Graph API. We have a couple of demos of interactive 3d geometry editing and display using Blazor wasm. This will create the database and seed the required data. My results are much better: < 100ms download and < 4 seconds for deserialize. When I attempt the same set of code in an automated integration test, it only takes 3 seconds or so (the download time). That is a serious problem for me FYI: I am using .NET 6 Preview 3 and System.Text.Json, I have had a similar journey recently moving through different serialisers and finally arriving at Messagepack which has been good enough in interpreted WASM for current users. This tells me there's no slowness in updating the DOM or rendering. For example, when I try to create an Excel file using EPPlus, ClosedXML, or similar APIs (I tried a bunch), it takes well over a minute for a 2MB file. the JSON file. I just did that comparison to ensure that the download speed is not relevant--regardless of whether the download is 20 ms or 20,000 ms, the deserialization is quite slow. Thanks, though. Connect and share knowledge within a single location that is structured and easy to search. Blazor is a free and open-source web framework that enables developers to create web apps using C# and HTML. It's just serialization and reading/writing bytes that seem to be a big issue. Some are in preview7 some are in later builds. The GetJsonAsync () method is an extension method for HttpClient, but it looks like what you are really trying to achieve here is one level of abstractiobn higher - i.e. In this crash course, we build an actual Blazor WebAssembly application based on .NET 5. Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. Does a creature have to see to be affected by the Fear spell initially since it is an illusion? See https://stackoverflow.com/q/63254162/. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. gRPC network usage is 70% smaller When the task completes, continue execution; that is, call UriHelper.NavigateTo('/Dashboard') synchronously. We will implement a simple data table and populate its data using an API call from the Blazor web application to an ASP.NET WebAPI . Running the Blazor code compiled using dotnet run -c release (non AOT) and viewing the console in Chrome shows: We found that AOT compilation (which takes nearly 15 minutes), increases the performance by 2x. I refactored to the code in the issue post just to narrow it down to slowness in deserialization. https://stackoverflow.com/questions/63254162, https://twitter.com/JamesNK/status/1310875638585204738, https://github.com/hypar-io/Elements/tree/wasm-perf/Elements.Wasm, https://github.com/hypar-io/Elements/tree/wasm-perf/Elements.Benchmarks, Can you share your hardware specs? (Download time on localhost is about 20 ms.) using the default code, await Http.GetFromJsonAsync<WeatherForecast []> ("WeatherForecast"); So this seems consistent with the timings on my slightly more complex case in the original question. In Program.cs, configure the MSAL authentication to use the custom user account factory: If the app uses a custom user account class that extends RemoteUserAccount, swap the custom user account class for RemoteUserAccount in the following code: The examples in this section use a named HttpClient for Graph API to obtain a user's mobile phone number to process a call. Different hardware and\or different Blazor versions could account for that 2x-3x slowness; would need a standard CPU benchmark and same Blazor version to actually compare apples-to-apples.". You'll see some build errors and will need to resolve some dependencies. RestClient.Net can do that in Blazor without the extra step. This may be the root of the problem. I couldn't figure out the best area label to add to this issue. Create or load a JSON file under the wwwroot folder. You signed in with another tab or window. Describe the bug httpClient.GetJsonAsync is unable to parse JSON downloaded from API that contain null value To Reproduce @shipList @code { private List<Ship> shipList; HttpClient httpClient = new HttpClient() { BaseAddress = new Uri("ht. The learn-blazor site had been created at a point in time when there was no Blazor documentation at all available. I just did that comparison to ensure that the download speed is not relevant--regardless of whether the download is 20 ms or 20,000 ms, the deserialization is quite slow. Not the answer you're looking for? We will call it Create.razor. See info in area-owners.md if you want to be subscribed. @szalapski I can confirm without a doubt that the slowness is with the deserialization and not a system or environment issue. What is the purpose of a display name in built-in form components? As you can see from the code, I've passed a type parameter to the GetJsonAsync method. a Web API Core 3.0 Project, nothing fency, getting data at startup in the Index razor page is Yes I am using .NET 5. Call Graph API from a component using the Graph SDK. By clicking Sign up for GitHub, you agree to our terms of service and This doesn't seem right to me. Copyright 2001 - 2022 Syncfusion Inc. All Rights Reserved. Is it OK to check indirectly in a Bash if statement for exit codes if they are multiple? Fastest decay of Fourier transform of function of (one-sided or two-sided) exponential decay. Our initial benchmarks of rc1 are showing it to be slower in this area than interpreted mode. I have powerful dev machine. which explained me I had to use the HttpClientJsonExtensions, as mentioned in next fragment from the site: So, after downloading the samples and having a quick look at the RestApi.Client project (which contains the If you're using Visual Studio, when you copy API response into the clipboard, you can then use "Edit | Paste Special | Paste JSON as Classes" to generate . @tareqimbasher @szalapski 2MB json file is taking about 7 seconds to deserialize which is not acceptable. The app must have the User.Read Graph API scope configured in AAD. GetFromJsonAsync (HttpClient, Uri, Type, JsonSerializerOptions, CancellationToken) Sends a GET request to the specified Uri and returns the value that results from deserializing the response body as JSON in an asynchronous operation. I'm already avoiding non-generic lists and objects that are of type System.Object. We're finding ways to manage things, but it does seem like there ought to be a way to get 50,000 small objects deserialized in a second or two. Already on GitHub? The StackOverflow test runs <4 seconds for @HenkHolterman and 7-12 seconds for @szalapski. [wwwroot/employee.json] @steveharter , I tried it just as suggested. If you're using Visual Studio, you'll see it's nested "inside" the Blazor component. I am not 100% sure but it seems very likely that this is related: I just tried to deserialize a 2.6MB json containing 10.000 simple POCOs. - limit attaching the access token to only URLs under the specified subpath. It looks like this is a question about how to use ASP.NET Core. rev2022.11.3.43005. We can write both client-side and server-side code in C#.NET itself. Foo is actually as follows, with minimal name changes only to protect the proprietary. I see that MessagePack claims to be ~13x faster deserializing than Json.NET (no benchmark for STJ) for the case of "large array of simple objects". First, and most importantly, thanks to the team working on Blazor and web assembly. Yes, I used the extensions, but when I saw they were slow, I refactored to the code above so I could narrow the issue down to serialization. Documentation is now available on docs.microsoft.com. Does the 0m elevation height of a Digital Elevation Model (Copernicus DEM) correspond to mean sea level? Why don't we consider drain-bulk voltage instead of source-bulk voltage in body effect? Not really a bug per say, but the new GetFromJsonAsync method is ~20% slower than the GetJsonAsync method in Blazor WASM in my (admittedly extremely primitive) perf testing.I was gonna write up a blog post on the perf improvements after 3.2 Preview 3 dropped, but was surprised to see the significant drop in perf. Running the same exact code on Blazor server produces the file in about a second. Use the HttpClient class with the GetFromJsonAsync() method to read a JSON file in Blazor WebAssembly. I have setup a database model and an API for users (/api/users) and browsing to this in chrome returns all of the entities in the database. PutAsJsonAsync: Sends an HTTP PUT request, including JSON-encoded content. 0 0 Question text/sourcefragment 2/25/2021 9:50:53 PM Anonymous 0 Also looping in @Gytaco who is doing some amazing work using c#->web assembly for geometry stuff. We use several third party dlls that we had to compile with .NET 6 as well to even get the publishing of the Blazor project to work. For more information, see the examples in Customize the user with a payload claim section. The 1-6 seconds was over the internet, whereas the 20ms was running against a local web service. When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. I suggest running the perf test that @HenkHolterman suggested in stackoverflow to compare against the baseline. How can this be achieved then on a Blazor Server based app ? privacy statement. I did start with a stream per the code just above --that was how I found this issue. Blazor Server and Blazor WebAssembly. The 1-6 seconds was over the internet, whereas the 20ms was running against a local web service. It's a pleasure to use. Interested to see how your times would change when you try it on Blazor 5 preview 8! In chrome the deserialization took took ~4 seconds (that's actually "good enough" for me, at least right now) Just tried outside of VS -- using dotnet run at the command line in Windows. Is any callback handler available for achieve my case? (as shown at the beginning of my request), it doesnt have the extension method for executing GetJsonAsync() Now open Visual Studio 2022 and follow the below steps. Refer to this documentation for more details. This is where we populate a form with our Team entity, which includes name, shirt colour and location. Let's create a description of a dynamic component: My controller in this example is returning an IEnumerable which is just a WeatherForecast[] (ordinary array) underneath. I see this is being targeted for .NET7. @using System.Net.Http @using System.Net.Http.Json By clicking Sign up for GitHub, you agree to our terms of service and I have tried like this below code, Error CS0029 - Cannot implicitly convert type System.Threading.Tasks.Task' to 'Application1.Models.DBModel'. Confirm correct package versions at NuGet.org. In the Blazor client-side application, you can call the web APIs using HttpClient service. deserialization to an array of Customer s. RestClient.Net can do that in Blazor without the extra step. Why does Q1 turn on and Q2 turn off when I apply 5 V? I do hope that you're not the presenter in the video. You can find the corresponding benchmark WasmComparison here: Have a question about this project? @inject HttpClient Httpclient <button @onclick="@GetData">Get Data</button> @code { private async Task GetData . Running it from Visual Studio, "run without debugging" in Release configuration. Some considerations as to what might be slow: You can find our example Blazor project that has no UI but runs the wasm and reports to the console here: https://github.com/hypar-io/Elements/tree/wasm-perf/Elements.Wasm. "Both Newtonsoft and STJ are slow. This code works on both the server-side and client-side rendering and avoids the need to call GetJsonAsync. Is this just slow deserialization in ReadFromJsonAsync (which calls System.Text.Json.JsonSerializer.Deserialize internally), or is there something else going on here? The initial release target is to ship this as a standalone NuGet package at Build, alongside Blazor, which will utilise the APIs. These include large strings (say > 1K) and using System.Object or a non-generic collection such as IList (where elements are System.Object) as a property type. This implementation will cause AccessTokenNotAvailableException exception when the user is not signed-in even if the accessing is for an anonymously accessible endpoint. It will not be used for any other purpose. privacy statement. Also tried running the .exe after running dotnet publish --configuration Release, just to be sure. Use the HttpClient class with the GetFromJsonAsync () method to read a JSON file in Blazor WebAssembly. I've been having similar issues. Stack Overflow for Teams is moving to its own domain! public async Task<List<YourDataModel>> GetMyDataAsync () { return await _httpClient.GetJsonAsync<List<YourDataModel>> (pathToYourJsonFileHere)} In your startup.cs file, modify the ConfigureServices method: //DI for HttpClient if (!services.Any (x => x.ServiceType == typeOf (HttpClient))) { services.AddSingleton<HttpClient> (); //DI for your service For what it's worth, here's the Chrome performance graph. Already on GitHub? So we can not realize our application with Blazor. The requested data as a json-string which is finally deserialized to the required object-type. The initial work has now been completed by David Cantu at Microsoft and has been merged, ready to the upcoming Blazor release. You'll want to avoid creating a string from the content and use a Stream instead. I posted an MCVE as answer on StackOverflow, based on the WeatherForecast page. Memory\CPU. Now read what you wrote again: When you 'll create a blazor project then you 'll have to choose blazor server app. Or advice how to route a page after data fetch got success. For now we've had to build our own. which can be found here: https://github.com/software-architects/learn-blazor/tree/master/samples/RestApi. This is your code, a copy of your code, which is why it is "("Dashboard")" instead of "("/Dashboard")". Maybe it's my misunderstanding of how serialisation works - is it object construction in .Net itself being slow here and I shouldn't see any difference between AOT and interpreted builds? To learn more, see our tips on writing great answers. How to use Http.GetJsonAsync() in Blazor Server App? We have a 20 member team and everyone from developers to business experiences this slowness of deserialization so I can state from experience that it is not a system or environment issue. You can find the corresponding benchmark WasmComparison here: While we do our best to look through all the issues filed here, to get a faster response we suggest posting your questions to StackOverflow using the asp.net-core-mvc tag. So download time went from 1-6 seconds for 2-6MB to 20ms for 1.6MB -- any thought on why that's the case? Cut and paste everything inside the @code block to the new file. If so, is the only solution to retrieve very small data sets everywhere on my site? The GetFromJsonAsync method is used to get the parsed Json data. We can register this as a Singleton (if we're using Blazor Web Assembly, in program.cs). but thought I'd ask--anything else we could do to "help" the deserializer along for collections with thousands of items? By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. I am using a PipeReader and Utf8Json is still faster even though I have to copy the bytes to an array to deserialize while with STJ it can be read directly. In blazor client side application, can read and data from json file async way. @tareqimbasher are you running on Blazor 5? The app must have the User.Read Graph API scope configured in AAD. The examples in this section require package references for the standalone or Client app: For guidance on adding packages to .NET apps, see the articles under Install and manage packages at Package consumption workflow (NuGet documentation). Both are fast with small payloads. Posted 9:05:43 PM. Here's the resulting browser console log from running the above code: Using Newtonsoft.Json (as in the commented-out line) instead of System.Text.Json gives very similar results. empList = await Http.GetJsonAsync<Employee []> ("api/Employee"); Note the removal of the leading "/" in the url. We can call methods in our library that do some pretty complicated geometry stuff and they run at near native speed. You'll want to avoid creating a string from the content and use a Stream instead. Thanks guys, sharing your valuable suggestion. This is how this can work in the server-side Blazor: Add reference to Microsoft.AspNetCore.Blazor.HttpClient package. Change to Async\Stream mode as mentioned earlier. Are the optimizations we see in .NET Core just not possible in WebAssembly? Are you running this test from inside VS or from a published build? However, scope of our WASM app is definitely expanding and we have users looking to handle 100s of thousands of of objects to perform data manipulation/analysis in browser like Excel would chomp through on a normal desktop. Can this slowness be fixed? In the following example, the app creates a mobile phone number claim for a user from their AAD user profile's mobile phone number. Serialisation is slow across all browsers for Mono .Net. Above way page routing happened once data fetch complete. For example, pass the User.Read scope to AddGraphClient for the examples in the following sections of this article: This section uses the utility classes (GraphClientExtensions.cs) described earlier in this article. (FYI, this is on Blazor 3.2.0; I also updated System.Text.Json via NuGet to v 5.0.0-preview.7, but it didn't help much. I have commented out anything bound to Results to simplify, and instead I just have an indicator bound to IsLoading. Anyhow, your new code snippet, which you say is working, is actually the first code snippet implemented in two methods, and thus, if it works as two methods, it should work as a single combined method. Tagging subscribers to this area: @CoffeeFlux The examples in this section require a package reference for Microsoft.Extensions.Http for the standalone or Client app. However, there are a couple areas known to be slow that could be made faster in the serializer. Please, remove your advertisement. Do you get it ? This example sends a new article in the postBody to the /api/articles route and then converts the response to an Article object and assigns it to the blazor component property article so it can be displayed in the component template. System.Text.Json should be ~2x faster for deserialization than Newtonsoft so it would be good to see your object model to see if you hit an area that is slow on STJ. Anyhow, your new code snippet, which you say is working, is actually the first code snippet implemented in two methods, and thus, if it works as two methods, it should work as a single combined method. The green is the download and the orange is "perform microtasks", which I assume means WebAssembly work. Blazor Server for production was already available. Customize user claims with the Graph SDK. The text was updated successfully, but these errors were encountered: UriHelper.NavigateTo is called only after the GetJsonAsync is completed. Please do it if you can, so that I'll be sure that I need some practice, or just remove the link. There are two hosting models available for Blazor. After adding the Microsoft Graph API scopes in the AAD area of the Azure portal: Add the following GraphClientExtensions.cs class to the standalone app or Client app of a hosted Blazor WebAssembly solution. Sign in implemented as next: And the service which hides the external API-call is implemented as next: So Im using the regular GetStringAsync() method on the created http client instance which returns public class ApiResponse { public int offset { get; set; } public int total { get; set; } public NameRec [] names { get; set; } } public class NameRec { public string name { get; set; } } ps. The Large object graph benchmark section in #40318 has deserialization perf of 372ms for a string of length 322K. Microsoft Graph SDKs are designed to simplify building high-quality, efficient, and resilient applications that access Microsoft Graph. But I can see significant gap if I use Balanced/PowerSaver setting. Blazor is a framework built by Microsoft for creating interactive client-side web UI with .NET codebase. It took around 13 seconds to get 53,000 weather forecasts in v 3.1 but 7 seconds in 5.0.0-rc1. In VS2019 (Version 16.3.8) for ordering pizzas. Hopefully you will see a large improvement on Blazor 5. That model is simple and should be fast (no System.Object, non-generic collections or custom converters that could slow it down). C# Copy I assume no attempt to run on Blazor 5.0 yet? Anyway, extrapolating 332K to your 1MB is a 3x factor, so I assume it would take about 372ms * 3 = ~1.1 seconds to deserialize (on my fast desktop in isolation). @steveharter Yes this will allow the deserializer to start before all of the data is read from the Stream and prevent the string alloc. protected override async Task OnInitializedAsync() { image = await http.GetFromJsonAsync<Data.Image>("api/image"); } Wait, what is that http reference? Different hardware and\or different Blazor versions could account for that 2x-3x slowness; would need a standard CPU benchmark and same Blazor version to actually compare apples-to-apples. We think this technology has a really bright future! We have an .NET open source library that is used heavily in back end services run on AWS Lambda. It is expected to be included as part of the BCL in an upcoming .NET 5 preview. Would a deserialization of a few megabytes take 10-30 s? I'll add my support for @szalapski here. @enetstudio : Actually i am using client side blazor application, your solution not work with my scenario. The Blazor/WASM community has generally always expressed that code runs at native speeds (until you learn that everything outside of the .net libraries is interpreted) and I had hoped AOT would make an enormous difference here, allowing Messagepack serialiser to run at native speed. I established a small benchmark that creates 1000 cubes using the library (the library is for creating 3d stuff with lots of Vector3 structs and Polygon), serializes them to JSON, then writes the resulting 3D model to glTF. What is the deepest Stockfish evaluation of the standard initial position that has ever been done?
