We integrated Address Doctor to verify address data for correctness.

Setup

First, activate the feature toggle addressDoctor.
You will also have to provide the endpoint and additional verification data.
This can be done by defining it in Angular CLI environment files:

export const environment: Environment = {
  ...ENVIRONMENT_DEFAULTS,

  addressDoctor: {
    url: '<addressDoctor-url>',
    login: '<addressDoctor-login>',
    password: '<addressDoctor-password>',
    maxResultCount: 5,
  },

This configuration can also be supplied via environment variable ADDRESS_DOCTOR as stringified JSON:

ADDRESS_DOCTOR='{ "addressDoctor": { "url": "<addressDoctor-url>", "login": "<addressDoctor-login>", "password": "<addressDoctor-password>", "maxResultCount": "5" } }';

Workflow

To check an address with the address doctor the PWA needs to render the <ish-lazy-address-doctor> component.
When the user submits the address data, the PWA needs to send a feature notification event with the request to check the data.

const id = this.featureEventService.sendNotification('addressDoctor', 'check-address', {
  address,
});

This method will submit the address data to the Address Doctor REST API and open a modal with all suggestions.
The user needs to decide and confirm the address, which is the correct one.
With the subscribe on the eventResultListener$ observable, the initial component can react on the confirmation data.

this.featureEventService
  .eventResultListener$('addressDoctor', 'check-address', id)
  .pipe(whenTruthy(), take(1), takeUntil(this.destroy$))
  .subscribe(({ address }) => {
    if (address) {
      this.accountFacade.updateCustomerAddress(address);
    }
  });
