Is there a way to preload templates when using AngularJS routing?

Question

After the Angular app is loaded I need some of the templates to be available offline.

Something like this would be ideal:

$routeProvider   .when('/p1', {     controller: controller1,     templateUrl: 'Template1.html',     preload: true   })

This is an addition to the answer by @gargc.

If you don't want to use the script tag to specify your template, and want to load templates from files, you can do something like this:

    myApp.run(function ($templateCache, $http) {         $http.get('Template1.html', { cache: $templateCache });     });      myApp.config(function ($locationProvider, $routeProvider) {         $routeProvider.when('/p1', { templateUrl: 'Template1.html' })     }); 

Answer 2

There is a template cache service: $templateCache which can be used to preload templates in a javascript module.

For example, taken from the docs:

var myApp = angular.module('myApp', []);   myApp.run(function($templateCache) {   $templateCache.put('templateId.html', 'This is the content of the template'); }); 

There is even a grunt task to pre-generate a javascript module from html files: grunt-angular-templates

Another way, perhaps less flexible, is using inline templates, for example, having a script tag like this in your index.html:

<script type="text/ng-template" id="templates/Template1.html">template content</script> 

means that the template can be addressed later in the same way as a real url in your route configuration (templateUrl: 'templates/Template1.html')
