Description

This project is a web server for group chat client application. Please refer to DistributedChatClient for the implementation of chat UI.

Technologies

• Chat server is a web API written using ASP.NET
• Chat client is an Angular Single page application
• Uses Microsoft.Identity.Web and MSAL to authorize the user to use chat server
• Establishes a web socket connection between browser and server on loading the page

Prerequisites

Requires an account with Azure AD tenant. Create App registration for both chat server and chat client in Azure portal

Chat server:

• Create a new App registration and enter a name for the application (Example: chat-server). In the Supported account types section, select Accounts in any organizational directory and personal Microsoft accounts (e.g. Skype, Xbox, Outlook.com).
• After it is created, click on Expose an API from the left menu
• Click on set Application ID URI
• Click on Add a scope and enter a name for the scope. Enter relevant text to display to user asking for consent.
• Replace the corresponding values in DistributedChatServer/appsettings.json

Chat client:

• Create a new App registration and enter a name for the application (Example: chat-client). In the Supported account types section, select Accounts in any organizational directory and personal Microsoft accounts (e.g. Skype, Xbox, Outlook.com).
• Click on Redirect URIs and then Add a platform
• Since our chat client is in Angular, click on single-page application
• Enter redirect URI of the application as https://localhost:4200. Once the user is successfully authenticated in Microsoft page, it gets redirected to this URI where our chat client is running
• Add the same URL https://localhost:4200 as Front-channel logout URL
• Select the checkboxes Access tokens and ID tokens
• Replace with corresponding values in DistributedChatClient/src/app/auth-config.ts
