Create Progressive Web Applications with Blazor WebAssembly

-

This article is going to explain how to create a Progressive Web Application (PWA) with Blazor WebAssembly with an example.

What is PWA

The PWA is a web application that acts like a native application using modern standards. You can install PWA on your computer. You can add a shortcut on the desktop and launch it in the start menu.

You can easily convert the Blazor application to PWA. Let's see what are things that need to create an installable web application.

  • A web manifest (The web manifest is a JSON file that tells the browser about your Progressive Web Application) [manifest.json]
  • HTTPS
  • A Service Worker with a functional fetch hander (So that your browser will recognize it is an installable app)

Let’s take a step-by-step look at how to create a Progressive Web Application through Blazor WebAssembly

Create a new project

In the create a new project window, choose Blazor App

Configure Your New Project

Enter the project name and location in Configure your new project window. I have entered SamplePWABlazorApp as a project name.

Create a new Blazor App

In this window, select Blazor Web Assembly and make sure the Configure for HTTPS checkbox is checked. Also, check the Progressive Web Application checkbox.

New Blazor project

Clicking the next button will create a new Blazor project.

Install PWA

The following figure illustrates how to install PWA. The browser detects whether the application can be installed while running the application. So it shows the + sign on the right side of the address bar. If you click the + sign, it will show a popup and ask for confirmation with the message Install App? Clicking the Install Application button will install it on your computer. This will automatically open the PWA application. Also, it will create a desktop icon for SamplePWABlazorApp and create a list in the start menu.

In the next picture, you can see how the PWA application works.

This will allow you to have multiple instances. So you can open multiple windows of PWA applications.

I hope this article is helpful to you. Keep coding.

This blog is going to explain what is SignalR and how to implement it in ASP.NET Core. SignalR is a real time application framework for ASP.NET Core. Using SignalR you can provide updated information without refreshing the page, for example poll results, game score, chat etc. Let's see how to achieve it in ASP.NET Core MVC. Step 1: First step I added the SignalR client library. To add a SignalR client library, Right click on the project in Solution Explorer and Add -> Client-Side Library. Select the provider as unpkg as shown in the image below. Enter the latest version of SignalR into the library. And selected signalr.js and signalr.min.js files. Finally clicked the install button to install the client library. Step 2: At this step I have created a VoteHub.cs class inside the Hubs folder(create a new folder called Hubs). This class inherits from the Hub class which is a base class of SignalR hub. The SendMessage method will be called by the connected client.

Using Query Strings for Request Culture and Simplifying Localization with IStringLocalizer Interface Let’s see how to implement Localization in ASP.NET Core MVC. In the first example, I am going to use the IStringLocalizer Interface in the controller to implement Localization. Additionally, when the user passes the desired language through the query string, it will display content in that language. First, let’s configure the settings in the program.cs file. builder.Services.AddLocalization(options => options.ResourcesPath = "Resources");  The AddLocalization method adds the localization service to the service container. I have added the supported cultures here. I have added two cultures: en for English and nl for Dutch. In the RequestCultureProviders , I have included QueryStringRequestCultureProvider() . This allows the system to determine the culture information from the query string. UseRequestLocalization initializes a RequestLocalizationOptions objec
