Rystem.Authentication.Social

This project would be a super project to help the api creator to have fast api behind business interfaces and services dispatched through dependency injection.

How to use it

You need to configure the social information and token settings, for instance the duration of your token.

builder.Services.AddSocialLogin(x =>
{
    x.Google.ClientId = builder.Configuration["SocialLogin:Google:ClientId"];
    x.Google.ClientSecret = builder.Configuration["SocialLogin:Google:ClientSecret"];
    x.Google.RedirectDomain = builder.Configuration["SocialLogin:Google:RedirectDomain"];
    x.Microsoft.ClientId = builder.Configuration["SocialLogin:Microsoft:ClientId"];
    x.Microsoft.ClientSecret = builder.Configuration["SocialLogin:Microsoft:ClientSecret"];
    x.Microsoft.RedirectDomain = builder.Configuration["SocialLogin:Microsoft:RedirectDomain"];
    x.Facebook.ClientId = builder.Configuration["SocialLogin:Facebook:ClientId"];
    x.Facebook.ClientSecret = builder.Configuration["SocialLogin:Facebook:ClientSecret"];
    x.Facebook.RedirectDomain = builder.Configuration["SocialLogin:Facebook:RedirectDomain"];
},
x =>
{
    x.BearerTokenExpiration = TimeSpan.FromHours(1);
    x.RefreshTokenExpiration = TimeSpan.FromDays(10);
});

You need to add in the app builder section the endpoints

app.UseSocialLoginEndpoints();

You can add your provider for user

builder.Services.AddSocialUserProvider<SocialUserProvider>();

SocialUserProvider is a ISocialUserProvider, to call for instance a database or storage to fetch the information about the user with social username/email.

internal sealed class SocialUserProvider : ISocialUserProvider
{
    public Task<SocialUser> GetAsync(string username, IEnumerable<Claim> claims, CancellationToken cancellationToken)
    {
        return Task.FromResult(new SuperSocialUser
        {
            Username = $"a {username}",
            Email = username
        } as SocialUser);
    }

    public async IAsyncEnumerable<Claim> GetClaimsAsync(string? username, CancellationToken cancellationToken)
    {
        await Task.CompletedTask;
        yield return new Claim(ClaimTypes.Name, username!);
        yield return new Claim(ClaimTypes.Upn, "something");
    }
}

public sealed class SuperSocialUser : SocialUser
{
    public string Email { get; set; }
}
