Features

Framework:

• NET 5.0

GUI:

• Blazor [Engine]
• MudBlazor (Bootstrap alternative) [GUI]

API:

• HTTPS
• GRPC-WEB (suggested mode as it is more intuitive becouse has strong types and supports ServiceReference in VisualStudio 2019+)
• HTTP (Alpha stage support derived directly from GRPC endpoint, alternatively you will need to create a dedicated HTTP endpoints but its not too productive)
  • Swagger as automatic API descriptor (HTTP)
• Authentication
  • Initially: Username + Password (eventually password passed Hashed)
  • Generation of JWT Token (for now without expiring date)
  • Use of JWT Token for any website navigation, GRPC call or HTTP call
    • Retrieve user data from Token and eventual activity tracing
  • Negate API access if Token is not valid
• Testable with BloomRPC / Postman (regarding HTTP endpoint)

Backend to Frontend (without additional protection):

• Push notifications through SignalR (internal dedicated channel)

Server to Subscribers (without additional protection):

• Push notifications through SignalR (public dedicated channel)
• Instead of WebSocket, SignalR was preferred for its simplicity, which anyway can use WebSocket (eventually still to review)

Multi Language:

• i18ntext
  • will allow to change website translations in realtime
  • also will allow to change translations without re-compiling project as they will be generated and saved as JSON File
  • will provide coding intellisense in order to retrieve correct translations keys faster (1 prior compilation needed after adding something new in transaltions)

Custom Authentication Tag:

• Can be used to read JWT tokens correctly and to use Roles as you would do normally (original Authentication Roles might not work with JWT token)
• Location: Shared/Auth/CustomAuthorization.razor
