Call REST API from ASP NET Core Blazor 

I needed this so much, you saved me from a deadline. Thank you So Much

Love this playlist!

Thank You Sir. God Bless You.

Very good tutorial Venkat. Thank you.

Great Venkat.

I love the Venkat!

Thank you Mr.

a great video! thanks

Great, I do it. Thank you very much, please keeping up

Here is a small piece of code to call the API. This is generic so that we don't need to write the code again and again. //THE INTERFACE public interface IApiHandler { Task GetAsync(string url); } //THE IMPLEMENTATION TO CALL THE API public class ApiHandler : IApiHandler { private readonly HttpClient _httpClient; public ApiHandler(HttpClient httpClient) { _httpClient = httpClient; } public async Task GetAsync(string url) { return await _httpClient.GetJsonAsync(url); } //TODO //CODE FOR POST, PUT, DELETE CAN BE ADDED } //THE STARTUP CLASS services.AddHttpClient(client => { client.BaseAddress = new Uri("localhost:44336/"); //ADD YOUR BASE URL INSIDE THE BRACKET }); //CALLING THE SERVICE(ApiHandler) public class EmployeeListBase : ComponentBase { [Inject] private IApiHandler _apiHandler { get; set; } public IEnumerable Employees { get; set; } protected override async Task OnInitializedAsync() { Employees = await _apiHandler.GetAsync("api/Employees/GetEmployees"); } }

Nice presentation

You are doing an excellent job

I really like your work arrangements .. just wondering why you didn't use generic repository and unit of work .. it's more usable

Thank you so much. I have a question. what is the alternatives for Microsoft.AspNetCore.Components namespace since this is in preview

Thank you. I would like to let you know that while testing on creating a new employee, I happened to find a false error of email address already exists for a new client and new email address, I ran the application in debug mode and postman for this very lesson. It would be nice to give an explanation as to why that happened as I was expecting to commit the new employee without any problem.

please sir what do you think about using Refit and create an SDK to consume the API?

Sir may i ask, why you are using Httpclientfactory instead of signalr to connect to the API? Like what the browser does to connect to blazor server? thank you in advance.😊😊

Thank you but i tried to use a generic service instead (ApiService) which implement (IApiService) then i tried to register it the same way you did but that didn't work can you please tell me a hint how to achieve this please.

Thanks Venkat, great job. I've been doing my head in trying to get this very thing working and here it all is in one tidy package. When the product is deployed the hard-coded base URL will not work, how would you set that up so it can be different and automatically set in each deployment environment please?

Thanks a lot for all your great tutorials. about this video - in 3:20 you are talking about Startup.cs file. but in web assembly project, there is just Program.cs file.

Plz start tutorial of C# WPF

Microsoft.AspNetCore.Blazor.HttpClient NuGet package is not available to download, however I searched in google and downloaded that package of version 3.2.0-preview3.20168.3 depricated. it is working to extract data from database using EFC and using API , but it is not working for Blazor app EmployeeListDetails :Shall you please provide that NuGet package.

I get it "An unhandled exception occurred while processing the request. JsonReaderException: '

I did a blunder while posting in postman, I posted it in different format and not in JSON. I cannot load the details on that page, but I am able to retrieve employees/1 or employees/2 except for the one that I wrongly posted. I do not know how to delete it as I tried to delete it, it showed some error. Anyone help me with this

can someone please explain to me why he uses services to call rest api when he already have a class library , when should we use class library or services

Is somewhere avaiable source code? I missed something and i would like to compare?

Most of the time, my seniors (some of them worked with Microsoft as well) suggested me not to use EF in our project. If this is true, why so?
