@tb01923 yes it does work for directives too.
In fact, it is working with any mechanism that use the $templateCache service (that means, directive, ng-include, ng-view, ...).
For those who are interested, I finally finished my extension to take care of this performance feature :
-> https://github.com/astik/grunt-angular-combine : it is a grunt plugin that merge partials file. You can merge all your partials int a single HTML files (like Vojta's example) to in as many module as you want (like my approach).
-> https://github.com/astik/angular-combine : it is an angular module (you'll need to add it to your application) that decorate the $templateCache (like in my previous post). A service is exposed for configuration (as we cannot decorate a provider, as far as I know).
Hey guys, awesome work!
when this code run:
$injector.get('$compile')(response.data);
Are the "internal" templates with in the combined template file pushed into $templateCache service somehow?
I assume they are not, and thus i don't understand how a directive can use an internal template from within the combined template file that we pre-fetched earlier.
Many thanks.
Yes.
All internal templates within the combined template file will be pushed into $templateCache once compiled.
I really appreciate this example and discussion.
I wrote up a few tests for this if anyone is interested. This my first spec, so comments are welcome. https://gist.github.com/tdg5/8783501
I merged all html files into single html file and i include inside app.js file but again its loading that single file and also all html files. plz give correct way to load only merge.html alone with result from test1,test2.html files
see the link i posted: http://plnkr.co/edit/3miUeU2EhS4syZhvrGey?p=preview
plz give correct way to load only merge.html alone but not all html files
hi vojtajina, your example is very good . and also work around for me . But I have some questions . hope you can help to review them.
I found actually the angularjs(1.2.16) already has a service named "$templateCache" which is implemented by $provide.
and I found the fakeTemplateCache.js is behind the angular js .
So it seems the factory "$templateCache" in your example overwrite the implement of original provider "$templateCache". right ?
For any one struggling for AngularJS 1.3 compatibility, esp. with the below error, here is the fix.
I've similar module in my project. It is working fine until I upgrade to AngularJS 1.3, after which the script is throwing below error:
TypeError: undefined is not a function

This could be related to angular/angular.js#2973 (also, report here nervgh/angular-file-upload#272) - not sure though.
Fix for this simple - we need to return headers too from the combinedTplPromise.then function, like below: (I m using astik's version - https://gist.github.com/vojtajina/3354046#comment-814584)
combinedTplPromise.then(function(response) {
return {
status: response.status,
data: origGetMethod(url),
headers: response.headers
};
});
Hope this will be useful to someone else. Same fix is reported here too: astik/angular-combine#2
Also, I recommend https://github.com/astik/angular-combine which extends this technique to support multiple combined template files.
@manikantag I just ran into the same issue and your solution fixed my problem, so thank you!
One thing I'm wondering though, is whether it'd be safer to do this instead:
combinedTplPromise.then(function(response) {
response.data = origGetMethod(url);
return response;
});
This way any future changes to the response object will make it through safely, as we're really only caching the response data. Thoughts?
@tdg5, thanks for the testing bootstrap, it motivates me to add some on my plugin ; I know it's been a while, but, better late than never =)
Anyway, just for information, https://github.com/astik/angular-combine is still alive as of its counterpart https://github.com/astik/grunt-angular-combine.
Feel free to participate =)
Thank you for the code!
I just patch it in case partial.tmpl doesn't exist (like in a environment development)
app.factory('$templateCache', function($cacheFactory, $http, $injector) {
var cache = $cacheFactory('templates');
var allTplPromise;
return {
get: function(url) {
var fromCache = cache.get(url);
// already have required template in the cache
if (fromCache) {
return fromCache;
}
// first template request ever - get the all tpl file
if (!allTplPromise) {
allTplPromise = $http.get('partial.tmpl').then(function(response) {
// compile the response, which will put stuff into the cache
$injector.get('$compile')(response.data);
return response;
});
}
// return the all-tpl promise to all template requests
return allTplPromise.then(function(response) {
return {
status: response.status,
data: cache.get(url)
};
}).catch(function(){
return $http.get(url).then(function(response) {
$injector.get('$compile')(response.data);
return response;
});
});
},
put: function(key, value) {
cache.put(key, value);
}
};
});
is there any problem if i use this code
app.run(function($http, $templateCache){
$http.get('all-templates.html').then(function(response) {
var $html = $('<div />',{html:response.data});
var elements=$html.find('script');
angular.forEach(elements,function(element){
$templateCache.put(element.id,element.innerHTML);
});
});
});
Awesome!!
hello guys...i am facing with one problem in ionic2...i want linked index.html page with second page of app..how to do it???
In actual have an svg iamge n second page of ionic2 which should be fill with color on click, by accessing index.html file
@yogeshgadge there is no incompatibility with VCS =)
Indeed, having all partials into a single HTML file (like Vojta's example) is no go for me either. That is why my approach is more modular.
