I am aware of a similar question being asked before:
Change the templateUrl of directive based on screen resolution AngularJS
This was first asked over a year ago and since then AngularJS got changed a bit. I am curious to find out if there are any other ways to achieve something similar as I haven't found many information about templateUrl swapping, so maybe I am barking up the wrong tree here.
I have a single page app without any routes.
html:
<body ng-app="App">
// lots of html same for both desktop/mobile
<my-dir></my-dir>
// even more here
</body>
template 1:
<p>Mobile</p>
template 2:
<p>Desktop</p>
I would like to render template 1 when the screen goes below 700px and template 2 otherwise. The templates change just what is inside my-dir directive. For example Template 1 renders list and template 2 renders table.
Another requirement would be to make it responsive if possible(aka templates would change as you resize the window)
At the moment I can use the solution from the above questions but are there any other ways to do it?

By using media query you can specify any size of any element in any display size like this: @media (min-width: 640px) { body {font-size:1rem;} } @media (min-width:960px) { body {font-size:1.2rem;} }
The best way to create a responsive layout is to use ConstraintLayout as the base layout in your UI. ConstraintLayout enables you to specify the position and size of each view according to spatial relationships with other views in the layout. All the views can then move and resize together as the screen size changes.
In your controller:
$scope.includeDesktopTemplate = false;
$scope.includeMobileTemplate = false;
var screenWidth = $window.innerWidth;
if (screenWidth < 700){
$scope.includeMobileTemplate = true;
}else{
$scope.includeDesktopTemplate = true;
}
html template:
<body ng-app="App">
<p ng-if="includeMobileTemplate">Mobile</p>
<p ng-if="includeDesktopTemplate">Desktop</p>
</body>

You can add window resize and scroll event listener on my-dir directive:
angular.module("App").directive('myDir', ['$window', '$timeout', function($window, $timeout){
return {
restrict: 'EA',
scope: {},
template:'<div>
<p ng-if="showFirstTemplate">Mobile</p>
<p ng-if="showSecondTemplate">Desktop</p>
</div>',
link: function(scope, element, attr){
function checkTemplateVisible(event){
//use $timeout to make sure $apply called in a time manner
$timeout(function(){
//pageYoffset is equal to window scroll top position
if($window.pageYOffset > 700){
scope.showFirstTemplate = true;
scope.showSecondTemplate = false;
}else{
scope.showFirstTemplate = false;
scope.showSecondTemplate = true;
}
})
})
//scroll event make sure checkTemplateVisible called on browser scrolling
$window.on('scroll', checkTemplateVisible)
//resize event make sure checkTemplateVisible called on browser resizing
$window.on('resize', checkTemplateVisible)
}
}
}])
