Streamlining Your Website with AngularJS - Consolidating Multiple Files into One

As a novice in AngularJS, I encountered an issue with using grunt-contrib-less to handle less files instead of css. After installing it, I found myself having to declare all the less styles that need to be compiled into one css file.

The challenge for me is that normally when working with less, I would write specific code for each page. However, in this case, I have to write style code for all pages which can be confusing and challenging to maintain. So, I have been wondering if there is a best practice for organizing less styles?

I considered several possible solutions:

Applying a class to the body tag and changing it using certain triggers (such as controllers or services) (Import LESS file only for one page)
Generating multiple css files depending on which style needs to be compiled (although configuring grunt for this may be tricky)
Using DOM manipulation (but I don't find this approach elegant as Angular should offer a better solution)

Can someone guide me on how to implement different styles for different views? I aim to avoid having the same style applied to all elements in all views without creating excessive classes.

Answer №1

Utilize the directive feature in your code

You have the freedom to incorporate any variables, code, or logic you desire

The HTML template (directive) allows you to customize the style of your view, resulting in a unique interface for all your views after compilation

To solve the issue, I implemented a solution where a specific class is added to the body tag based on the route being accessed. I created a variable in rootScope named 'pageStyle' that corresponds to the desired classname. This variable gets automatically updated whenever there is a change in the route (see the run function). An event is triggered when the route changes ($stateChangeSuccess or $routeChangeSuccess depending on whether ngRoute or angular-ui-router is used).

In my scenario, I opted to include the route name in the classname, but this can be customized to use the controller name or any other identifier.

Here's an example:

Defined routes:

angular
  .module('frontApp', [])
  .config(['$stateProvider', '$urlRouterProvider', function ($stateProvider, $urlRouterProvider, $mdThemingProvider) {
    $urlRouterProvider.otherwise('/');
    $stateProvider
      .state('home', {
        url: '/',
        templateUrl: '../views/home.html',
        controller: function ($scope) {
          $scope.msg = 'Xavier';
        }
      })
      .state('form', {
        url: '/form',
        templateUrl: '../views/form.html',
        controller: 'FormCtrl'
      });
  }])

The run function includes the event binding to update the class upon route change:

.run(function($rootScope) {
    $rootScope.pageStyle = '';
    // Watch state and set controller name in pageStyle variable when state changes
    $rootScope.$on('$stateChangeSuccess', function(event, toState) {
      event.preventDefault();
      if (toState && toState.name && typeof toState.name === 'string'){
        $rootScope.pageStyle = toState.name;
      } else {
        $rootScope.pageStyle = '';
      }
    });
});

Additional information:

Note that the event triggered upon route change varies depending on whether ngRoute or angular-ui-router is utilized. Use "$routeChangeSuccess" for ngRoute and "$stateChangeSuccess" for angular-ui-router.
If you prefer to include the controller name instead of the route name, you can modify the following code by replacing 'ctrl' with your controller suffix:

if (toState && toState.controller && typeof toState.controller !== 'function'){
    $rootScope.pageStyle = toState.controller.toLowerCase().replace('ctrl','');
}

I hope this explanation proves useful to others!
