DefaultJwtAuthentication

A default implementation for authentication using jwt and refresh tokens with identity core. It also allows for easy extending with your own user properties and dbsets.

How to use

Using dependency injection:

AddDefaultJwtAuthentication<TUserAuthenticationService>(this IServiceCollection services, 
            TokenValidationParameters parameters) where TUserAuthenticationService : class, IUserAuthenticationService
            
AddDefaultJwtDbContext<TAppUser, TDbContext>(this IServiceCollection services,
            string connectionString) where TAppUser : AppUser where TDbContext : AbstractAppDbContext<TAppUser>
            

For this to work IUserAuthenticationService, AppUser, AbstractAppDbContext<TAppUser> must be implemented.

Implementing IUserAuthenticationService

This is the service which handles the authentication of users. It is recommended to use UserRepository<T> to interact with the db.

Authenticate

In this method the AppUserLogin attempt should be authenticated. Usage of IUserRepository<T>.Authenticate is recommended.

Create

In this method the AppUserCreate attempt should be used to create a user. Usage of IUserRepository<T>.Create is recommended.

Refresh

In this method the jwt and the refresh token should be used to authenticate a user. Usage of IUserRepository<T>.RefreshToken is recommended.

Implementing AppUser

An abstract class which extends the IdentityUser class from Microsoft.AspNetCore.Identity with the following fields FirstName, LastName and RefreshTokens.

The AppUser class should be extended with a custom user class. If needed, additional properties can be added to the class.

Implementing AbstractAppDbContext

An abstract class which extends the IdentityDbContext<T> class from Microsoft.AspNetCore.Identity with a DbSet of refresh tokens.

The AbstractAppDbContext<TAppUser> class should be extended with a DbContext class. If needed, additional DbSets can be added. Of course, TAppUser should be your own implementation of AppUser as mentioned before.

IUserActionResult

A data object used to return the results of actions performed by the IUserRepository.

Additional extendability

AppUserCreate and AppUserLogin can both be extended with custom properties.
