ANGULAR DEMO FRONTEND

This Angular Demo project was generated with Angular CLI version 8.x and demonstrates several aspects of Angular and the surrounding technologies. It might be a good starting point for Angular projects with a similar technology stack, or just can be used to test new technologies or potential solutions for Angular related problems.

Actually the Angular Demo Frontend is the counter part of this String Boot Demo backend project. So besides a locally running Keycloak and Postgres instance, the Backend must have been started, also locally.

Note, once the BE and the FE has been started locally, navigate to http://localhost:4200 and login as super admin user in order to be able to access most of the implemented features, which are mainly user and role management related.

Major Tech-Stack

• Angular
• TypeScript
• Keycloak
• RxJS
• Bootstrap & SCSS (& Responsive design)
• Jasmine tests (almost 100% code coverage)
• Docker
• Sonarqube

BACKEND

An appropriate Spring Boot Demo backend is available within my GitHub account.

SETUP

Setup Backend

Please follow the setup instructions of the Spring Boot Demo backend project. Afterwards ensure that the backend itself and the required Docker images are running in Docker containers locally.

Setup Keycloak Docker Container

If you have chosen the pre-configured Keycloak Docker option during in the Spring Boot Demo backend project setup, the part "Manual Configuration of the Keycloak Docker Container" below can be skipped. Just start the Keycloak Docker container of the backend project and the Keycloak frontend requirements are there out of the box.

In case you have chosen the manual option while setting up the Keycloak Docker container during the backend setup, the following additional steps are required to make Keycloak usable for the frontend.

Manual Configuration of the Keycloak Docker Container

Start Keycloak and access the Keycloak Management Console

1. Ensure that the Docker container, that has been created during the backend project setup, is running.

    $ docker ps<br>
    $ docker ps -a<br>
    $ docker start demo-project-keycloak
   
    http://localhost:8100/auth/admin/master/console/#/realms/DemoProjectRealm
   

2. To access the Keycloak Administration Console navigate to http://localhost:8100 and enter the following credentials

   Username: nilsign@gmail.com
   Password: root

   Note, that the password for all other Keycloak Realm users is also root. This includes also new users that have been created via the UI of this frontend.

Create a Keycloak Realm Client (Frontend)

1. Switch the realm to DemoProjectRealm

2. Click to DemoProjectRealm->Configure->Clients->"Create"
   

   Client ID: DemoProjectAngularFrontendClient

3. Click to DemoProjectRealm->Configure->Clients->"DemoProjectAngularFrontendClient"
   

   Enabled: ON
   Valid Redirect URIs: http://localhost:4200/*
   Web Origins: +

Create and assign Keycloak DemoProjectRealm Client Roles

1. Click to DemoProjectRealm->Configure->Clients->DemoProjectAngularFrontendClient->Roles->"Add Role"
   

   Role Name: ROLE_REALM_CLIENT_ADMIN

   Repeat 1. with Role Name: ROLE_REALM_CLIENT_SELLER
   Repeat 1. with the Role Name: ROLE_REALM_CLIENT_BUYER
   

2. Click to DemoProjectRealm->Manage->Users-> ...

   ... nilsign->Role Mappings->Client Roles->"DemoProjectAngularFrontendClient"

   Select role ROLE_REALM_CLIENT_ADMIN and press "Add selected"

   ... ada->Role Mappings->Client Roles->"DemoProjectAngularFrontendClient"

   Select role ROLE_REALM_CLIENT_ADMIN and press "Add selected"
   Select role ROLE_REALM_CLIENT_SELLER and press "Add selected"

   ... selma->Role Mappings->Client Roles->"DemoProjectAngularFrontendClient"

   Select role ROLE_REALM_CLIENT_SELLER and press "Add selected"

   ... bud->Role Mappings->Client Roles->"DemoProjectAngularFrontendClient"

   Select role ROLE_REALM_CLIENT_BUYER and press "Add se

Update Keycloak's Client Authenticator Secret in the Code

Open the 'environment.ts files (at least for DEV) and set the correct (your) Keycloak's "client-secret".

Note, that the (in case of a manual setup) correct client secret can be found at

DemoProjectRealm->Configure->Clients->Account->"Credentials"

DEV TOOLS

Code Analysis

1. The backend's Sonarqube instance can be shared and will hold two projects, the backend and this frontend project, once the frontend code analysis has been executed the first time.

2. Run test with code coverage (to update Sonarqubes coverage information).

    $ ng test --code-coverage
   

3. Execute Sonarqube's code analysis.

    $ npm run sonar
   

4. Navigate to the to http://localhost:9000 and enter the default credentials to inspect the results

   Username: admin
   Password: admin

   More detailed information can be found on the official Sonarqube and Sonarqube Docker pages

   To customize the Sonarqube setup configuration adapt the sonar-project.properties.

Development Server

Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Build Project

Run ng build to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Running Unit Tests

Run ng test to execute the unit tests via Karma.

Running End-to-End Tests (Not maintained)

Run ng e2e to execute the end-to-end tests via Protractor.

Running Sonarqube

Run npm run sonar to analyse and measure the code quality. To see the results navigate to http://localhost:9000.

Note, that the locally running Sonarqube server instance of the backend can be used here as well. To setup an instance please have a look at the backend's readme.

POTENTIAL ROAD MAP

• Update to Angular 9.x
• Error Handling
• Buyer and seller content
• Integration tests (Cypress and/or Protractor)
• Redux (or a more lightweight solution)
• Storybook
