How to display a navbar on every page except landingpage, so that not have to attach a navbar file on each of needed pages? Now I have enclosed navbar on main app layout, how it should be handled to keep it DRY?

Demo (with navbar on each page):

var App = angular.module('app', ['ui.router']);
App.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider
    .state('home', {
      url: '/home',
      templateUrl: 'home.html'
    })
    .state('about', {
      url: '/about',
      templateUrl: 'about.html'
    }).state('landingpage', {
      url: '/landingpage',
      templateUrl: 'landingpage.html'
    });
  $urlRouterProvider.otherwise('/home');
});

• 3 In general, my way is to use few families of Hierarchies. E.g. Entities are having root/list/detail, while login has no hierarchy. Documentations can share root but end with root.doc... This way we can share lot of code, while still having ability to distinguish (by logical "families")... – Radim Köhler Commented Apr 11, 2015 at 9:09
• Set boolean value in your controller with respect to your $stateProvider state. – Olatunde Garuba Commented Apr 11, 2015 at 9:24

Created named views like <div ui-view name="nav"></div> and set the templateUrl by view by state. For the landingpage state, just don't provide a templateUrl for the nav view and it won't render the navbar.

Update: hide on landingpage not home state.

var App = angular.module('app', ['ui.router']);
App.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider
    .state('home', {
      url: '/home',
      views: {
        nav: {
          templateUrl: 'navbar.html'
        },
        content: {
          templateUrl: 'home.html'
        }
      }
    })
    .state('about', {
      url: '/about',
      views: {
        nav: {
          templateUrl: 'navbar.html'
        },
        content: {
          templateUrl: 'about.html'
        }
      } 
    }).state('landingpage', {
      url: '/landingpage',
      views: {
        content: {
          templateUrl: 'landingpage.html'
        }
      } 
    });
  $urlRouterProvider.otherwise('/home');
});
