Angular client towards a REST API by .NET 8 with C# using JWT and Refresh Tokens for Authentication

Traditional webhosting is used for this Application

• Try the demo

The Web API was made without the ASP.NET Core Identity using custom JWT middleware

• The Web API at GitHub
• The Angular Client at GitHub

Functionality of the Web App

• JWT authentication with Refresh Tokens
• Refresh token rotation
• Revoked token reuse detection

Tech used for building the Web App

• C#
• The .NET 8 Web API is hosted at a traditional Webhotel
• The Angular Client is hosted at a traditional Webhotel
• SQLite as the Database for both Dev + Prod
• CORS Policy implemented by .NET
• JWT Token for access secure routes
• Refresh Token by HTTP only Cookie to generate new JWT Tokens

By using JWT + Refresh Tokens the security will be improved. The JWT can have a reduced time to live and therefor less likely to be stolen
