Using Bootswatch themes with theme switcher
Tip submitted by @deepu105
To have Bootswatch themes instead of the default theme you just need to override the bootstrap css with the css from bootswatch theme. However if you want a cool theme switcher to switch between Bootswatch themes dynamically then follow this tip.
Make the following changes in the generated app.
Note: replace ‘yourApp’ with the generated name of your application.
Add Files
Add the below service as bootswatch.service.js under webapp/scripts/components/util
'use strict';
angular.module('yourApp')
.factory('BootSwatchService', function ($http) {
return {
get: function() {
return $http.get('http://bootswatch.com/api/3.json').then(function (response) {
return response.data.themes;
});
}
};
});
Add the below directive as bootswatch.directive.js under webapp/scripts/components/util
'use strict';
angular.module('yourApp')
.directive('jhSwitchTheme', function() {
/*Directive binds to anchor to update the bootswatch theme selected*/
return {
restrict: 'A',
scope: {
theme : '=jhSwitchTheme'
},
link: function (scope, element, attrs) {
var currentTheme = $("#bootswatch-css").attr('title');
if(scope.theme.name === currentTheme){
element.parent().addClass("active");
}
element.on('click',function(){
$("#bootswatch-css").attr("href", scope.theme.css);
$(".theme-link").removeClass("active");
element.parent().addClass("active");
});
}
};
});
Add the below controller as bootswatch.controller.js under webapp/scripts/components/util
'use strict';
angular.module('yourApp')
.controller('BootswatchController', function ($scope, BootSwatchService) {
/*Get the list of availabel bootswatch themes*/
BootSwatchService.get().then(function(themes) {
$scope.themes = themes;
$scope.themes.unshift({name:'Default',css:''});
});
});
index.html
Add the below to the index.html file after the CSS build task so that these are not minified and compacted by build task
<!-- build:css assets/styles/main.css -->
...
<!-- endbuild -->
<!-- placeholder link to load bootswatch themes, title holds the current applied theme name-->
<link rel="stylesheet" href="" id="bootswatch-css" title="Default">
Add the below in footer
<div class="footer">
<p translate="footer" class="pull-left">This is your footer</p>
<div ng-controller="BootswatchController" class="dropup pull-right">
<a class="btn btn-default dropdown-toggle" data-toggle="dropdown">
<span class="glyphicon glyphicon-adjust"></span>
<span class="hidden-tablet" translate="global.menu.theme">Theme</span>
<b class="caret"></b>
</a>
<ul class="dropdown-menu" role="menu">
<li class="theme-link" ng-repeat="theme in themes">
<a href="" jh-switch-theme="theme"></a>
</li>
</ul>
</div>
</div>
Add script tags in your index.html file so you don’t receive angular errors
<!-- build:js({.tmp,src/main/webapp}) scripts/app.js -->
...
<script src="scripts/components/util/bootswatch.controller.js"></script>
<script src="scripts/components/util/bootswatch.directive.js"></script>
<script src="scripts/components/util/bootswatch.service.js"></script>
app.js (only for oAuth/xAuth)
Add exclusion to the bootswatch url in authInterceptor in app.js if you are using OAuth or XAuth
.factory('authInterceptor', function ($rootScope, $q, $location, localStorageService) {
return {
// Add authorization token to headers
request: function (config) {
config.headers = config.headers || {};
// exclude bootswatch url
if(config.url.indexOf('api.bootswatch.com') === -1){
var token = localStorageService.get('token');
....
}
return config;
}
};
