Today I Learned

vuex-class' documentation doesn't come with clear steps on how one could call a getter with one or more arguments.

Here's how you do it:

  @workspaces.Getter
  protected workspace: WorkspaceType | null = null;
  
  public byId!: (id: WorkspaceId) => WorkspaceType;
  
  mounted(): void {
    this.workspace = this.byId({ id: this.activeWorkspaceId });
  }
