localisation service
new variable:
languageChanged = new Subject();

with...
import { Subject } from 'rxjs';

new method:

  public changeLanguage():void {
    this.languageChanged.next();
  }

l10n component

    if (current_language !== language) {
      this.localizationService.changeLanguage();
    }

each constructor now subscribes...

  constructor(
    private localizationService: LocalizationService,
    private cvItemService: CvItemService,
  ) {
    this.localizationService.languageChanged.subscribe(() => { this.getLocalization() });
  }

header component has to nuke the existing navLinks

  private populateNavLinks(): void {
    this.navLinks.splice(0, this.navLinks.length);
(etc)

...and constructor has a slightly different method
this.localizationService.languageChanged.subscribe(() => { this.getAllItems(); }

getAllItems replaces ngOnInit, which calls it:

  private getAllItems(): void {
    this.getLocalization();
    this.getFeatureToggles();
    this.getItems();
    this.populateNavLinks();
  }

  ngOnInit() {
    this.getAllItems();
  }

Realised that it's more efficient to not call getLocalization() each time, but just pass the data back.

this.localizationService.changeLanguage(language);

then

  public changeLanguage(language):void {
    this.languageChanged.next(L10N[language]);
  }

with, for each ...component.ts

  constructor(
    private localizationService: LocalizationService,
    private cvItemService: CvItemService
  ) {
    this.localizationService.languageChanged.subscribe((data) => { this.l10n = data });
  }

header.component.ts can be simplified, with the original ngOnInit(), with constructor

  constructor(
    private localizationService: LocalizationService,
    private featureToggleService: FeatureToggleService,
    private cvItemService: CvItemService,
    ) {
      this.localizationService.languageChanged.subscribe(
          (data) => {
            this.l10n = data;
            this.populateNavLinks();
          });
    }

@tobyharding Thank you for your guide how to achieve the language change without reload, that was very helpful!
