Hi I had the same issue with jquery in -prod and I was able to solve it by following the directions from here: #1118
See vaudy's and sqwk's answers.
Thanks

@unseen1980: Not sure what instructions you mean. If you'll look at my reference project, everything is configured properly. Have you ran your config as -prod? When you build for production, all thrid party libraries not in the polyfills array are merged into main.js and loaded at the end of index.html. In my builds, jQuery is loaded after my application JS files so they cannot reference jQuery. Other third party libraries are OK with jQuery in my configuration. So when I load bootstrap using the 3rd party configuration, bootstrap is OK. My problem is using jQuery in my app JS with this configuration.

It looks like one of two approaches will solve this:

1. custom configuration of polyfills array allowing inclusion of jQuery.
2. prioritize the merging of jQuery to make sure it is loaded before any app JS.

I would personally prefer to be able to include jQuery with the polyfills.

In the meantime, I am loading it manually above the polyfills from the CDN and including the typings definition in my project with the other polyfills definitions.

[unseen1980]

Ok, for me it was not loading the jquery at all.
Then maybe you need to declare var $:any;

[rkralston]

Looks like I pushed the wrong thing to my repo. That is fixed.

$ is used otherwise by one of the polyfills. (very irritating). I tried var jQuery: any;. That does not work either.

Once the page is entirely loaded, the jQuery object does get loaded into the global space. However, the problem is the order of loading. jQuery is not available for any of my app JS.

Closed as this issue was made obsolete by #1455.

[rkralston]

Just to clarify, upgrading to 11 should fix this?

Thanks, @filipesilva

[filipesilva]

@rkralston correct. beta.11 isn't out yet, but this week there should be a special preview release that you can install as angular-cli@webpack that lets you use the new build system. We'll also provide detailed upgrade instructions.
