HttpErrorResponse implements the Error interface structurally but does not extend the Error class, so `error instanceof Error` was always false for HTTP failures and every travel error (400/409/500/network) fell through to the same generic fallback string, hiding the backend's specific TravelDomainError code/message (e.g. TRAVEL_ALREADY_ACTIVE) from the user. toErrorMessage now checks `error instanceof HttpErrorResponse` first and maps known travel error codes to specific German messages, falling back to the generic message for unknown codes and to `error.message` for genuine non-HTTP errors. startTravel()'s catch block also now resyncs current travel state from the server (reusing the existing pollCurrentTravel/refreshCurrentTravel path) so a failed start caused by a race with another tab/request doesn't leave the store's local state stale.
Web
This project was generated using Angular CLI version 21.2.6.
Development server
To start a local development server, run:
ng serve
Once the server is running, open your browser and navigate to http://localhost:4200/. The application will automatically reload whenever you modify any of the source files.
Code scaffolding
Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
ng generate component component-name
For a complete list of available schematics (such as components, directives, or pipes), run:
ng generate --help
Building
To build the project run:
ng build
This will compile your project and store the build artifacts in the dist/ directory. By default, the production build optimizes your application for performance and speed.
Running unit tests
To execute unit tests with the Vitest test runner, use the following command:
ng test
Running end-to-end tests
For end-to-end (e2e) testing, run:
ng e2e
Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
