`ui-router` $stateParams vs. $state.params

Question

With ui-router, it\'s possible to inject either $state or $stateParams into a controller to get access to parameters in the URL. Howev

Answer 1

There are many differences between these two. But while working practically I have found that using $state.params better. When you use more and more parameters this might be confusing to maintain in $stateParams. where if we use multiple params which are not URL param $state is very useful

 .state('shopping-request', {
      url: '/shopping-request/{cartId}',
      data: {requireLogin: true},
      params : {role: null},
      views: {
        '': {templateUrl: 'views/templates/main.tpl.html', controller: "ShoppingRequestCtrl"},
        'body@shopping-request': {templateUrl: 'views/shops/shopping-request.html'},
        'footer@shopping-request': {templateUrl: 'views/templates/footer.tpl.html'},
        'header@shopping-request': {templateUrl: 'views/templates/header.tpl.html'}
      }
    })
