LocalizationProvider.AspNetCore 8.1.5

Supporting LocalizationProvider

If you find this library useful, cup of coffee would be awesome! You can support further development of the library via Paypal.

Localization Provider v8.0 IS OUT!

Read more about v8.0 release here.

What is the LocalizationProvider project?

LocalizationProvider project is ASP.NET Core web application localization provider on steroids.

Giving you the main following features:

• Database-driven localization provider for .Net applications
• Easy resource registrations via code
• Supports hierarchical resources (with the help of child classes)

Source Code Repos

The whole package of libraries is split into multiple git repos (with submodule linkage in between). Below is list of all related repositories:

• Main Repository
• .NET Runtime Repository
• Optimizely Integration Repository

Project Structure

Database localization provider is split into main abstraction projects and .NET Core support project (this).

Getting Started

Bare Minimum to Start With

Below are code fragments that are essential to get started with a localization provider.

Install required packages:

> dotnet add package LocalizationProvider.AspNetCore
> dotnet add package LocalizationProvider.AdminUI.AspNetCore
> dotnet add package LocalizationProvider.Storage.SqlServer

Following service configuration (usually in Startup.cs) is required to get the localization provider working:

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // add your authorization provider (asp.net identity, identity server, whichever..)
    
        services
            .AddControllersWithViews()
            .AddMvcLocalization();
    
        services.AddRazorPages();
        services.AddRouting();
    
        services.AddDbLocalizationProvider(_ =>
        {
            _.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
            ...
        });
    
        services.AddDbLocalizationProviderAdminUI(_ =>
        {
            ...
        });
    }

    ...
}

And following setup of the application is required as a minimum (also usually located in Startup.cs):

public class Startup
{
    ...

    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        app.UseRouting();
        app.UseAuthentication();
        app.UseAuthorization();
    
        app.UseDbLocalizationProvider();
        app.UseDbLocalizationProviderAdminUI();
        app.UseDbLocalizationClientsideProvider(); //assuming that you like also Javascript
    
        app.UseEndpoints(endpoints =>
        {
            endpoints.MapRazorPages();
            endpoints.MapDbLocalizationAdminUI();
            endpoints.MapDbLocalizationClientsideProvider();
        });
    }
}

You can grab some snippets from this sample Startup.cs file:

using DbLocalizationProvider.AspNetCore;

using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;

    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddDbContext<ApplicationDbContext>(
                options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services
                .AddDefaultIdentity<IdentityUser>()
                .AddRoles<IdentityRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>();

            services
                .AddControllersWithViews()
                .AddMvcLocalization();

            services.AddRazorPages();

            var supportedCultures = new List<CultureInfo> { new CultureInfo("sv"), new CultureInfo("no"), new CultureInfo("en") };

            services.Configure<RequestLocalizationOptions>(opts =>
            {
                opts.DefaultRequestCulture = new RequestCulture("en");
                opts.SupportedCultures = supportedCultures;
                opts.SupportedUICultures = supportedCultures;
            });

            services.AddDbLocalizationProvider(_ =>
            {
                _.EnableInvariantCultureFallback = true;
                _.ScanAllAssemblies = true;
                _.FallbackCultures.Try(supportedCultures);
                _.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"));
            });

            services.AddDbLocalizationProviderAdminUI(_ =>
            {
                _.RootUrl = "/localization-admin";
                _.ShowInvariantCulture = true;
                _.ShowHiddenResources = false;
                _.DefaultView = ResourceListView.Tree;
            });
        }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                app.UseHsts();
            }

            var options = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
            app.UseRequestLocalization(options.Value);

            app.UseRouting();
            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseAuthentication();
            app.UseAuthorization();

            app.UseDbLocalizationProvider();
            app.UseDbLocalizationProviderAdminUI();
            app.UseDbLocalizationClientsideProvider();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");
                endpoints.MapRazorPages();

                endpoints.MapDbLocalizationAdminUI();
                endpoints.MapDbLocalizationClientsideProvider();
            });
        }
    }
}

.NET Core support project has its own repo while main abstraction projects are included as submodules here.

How to Contribute

It's super cool if you read this section and are interesed how to help the library. Forking and playing around sample application is the fastest way to understand how localization provider is working and how to get started.

Forking and cloning repo is first step you do. Keep in mind that provider is split into couple repositories to keep thigns separated. Additional repos are pulled in as submodules. If you Git client does not support automatic checkout of the submodules, just execute this command at the root of the checkout directory:

git clone --recurse-submodules git://github.com/...

Building AdminUI.AspNetCore Project

You will need to run npm install at root of the project to get some of the dependencies downloaded to get started. Some files from these packages are embedded as part of the AdminUI - therefore compilation will fail without those files.
