Ts.ED - Passport Azure Ad

Here an example project with Passport.js and Ts.ED framework.

See Ts.ED project for more information.

Features

• Angular 8
• Microsoft Passport Azure AD
• Lerna && Yarn workspaces - monorepo manager
• PM2 - node process manager
• Docker and Docker compose
• Travis CI

Requirement

Because this project use lerna and workspaces, you have to install yarn before build and run project.

npm install -g yarn

Checkout

This repository provide getting started project example for each Ts.ED version since v5.18.1.

git checkout -b https://github.com/TypedProject/tsed-example-passport-azure-ad/tree/v5.18.1

To checkout another version just replace v5.18.1 by the desired version.

Install

Important! Ts.ED requires Node >= 8, Express >= 4 and TypeScript >= 3.

npm install

Run

npm start

Auth

This implements the Azure Single Page App Auth. The options are set in the:

• .env file for the server in development environment:
• Azure Application Settings for the server in the Azure environment
• environments/environment.*.ts for the Angular client in the chosen environment
  • To start Angular in the chosen environment run ng serve --port 4201 --configuration=dev for environment.dev.ts

The options are:

1. UseScopeLevelAuth=true - to enable (true) the use of scopes specified on the endpoints. For example:

    @Get("/hello-auth-world")
    @OAuthBearer({"scopes": ["admin"]})
    importantAdminTask(@Req() request: Express.Request, @Res() response: Express.Response) {
        ...
    }
   

However this comes at the cost of needing to define an application scope and assigning users to that. This is due to the way that Azure Active Directory currently works where at least one scope is required (that is, if there are endpoints that don't have explicit scopes then something needs to be sent to Azure AD for these).

If this option is true then the full set of possible scopes needs to be defined in Scopes in the server environment. The first one should be the application one that all users need to be assigned to.

2. UseScopeLevelAuth=false - to disable (false) the use of scopes specified on the endpoints. This means that the users only need to authenticate against an App registered in Azure AD. But no API Endpoints need to be defined.

Azure - set up the App as per:

• https://docs.microsoft.com/en-us/azure/active-directory/develop/scenario-spa-app-registration

Azure - create App Registration

• Azure > App Registrations > THE_APP > Expose an API to create scopes (roles).
• Add it to the app under Azure > App Registrations > THE_APP > API Permissions

Azure - set to use version 2 of token:

• Azure > App > App Active Directory > App Registrations > Manifest - set accessTokenAcceptedVersion=2

Roles - the scopes for an application need to be assigned to Users or Groups they belong to

• https://docs.microsoft.com/en-us/azure/active-directory/manage-apps/methods-for-assigning-users-and-groups

For TeD, users must be assigned to the 'ted.translations.search' scope.

There is an Azure developer's blog post on all this at https://joonasw.net/view/defining-permissions-and-roles-in-aad.

Copy the clientId that was created during the app registration process, and also the tennantId that is your organizations tennant. Paste these in to a ~/.env file and as Azure Application Settings in your Application Service.

Copy the scope(s) created and add them to the configuration in Server.ts.
