Is angular-hybrid compatible with AOT?

[JiriPelnar]

In our angularjs / angular hybrid application we use ui-router and it works great when using JIT. Now I am trying to make it work with AOT and all my effort seem to fail. First I tried using rollup and rollup for some reason fails to resolve angular-hybrid package. I then tried to make the application work using webpack, and while the bundling completed successfully, the states that I define inside angular 2 modules do not seem to be registered in the stateRegistry. Am I doing something completely wrong? Should this be working? If it should be working, I will try to reproduce it using a plunker.

Yes, AOT compatibility should work, if you follow all the steps listed in the README, or better yet copy the code from the example (it's more complete and up-to-date).

@mischkl thank you for your comment, I went through the README another time to check if I have left something important out. I believe I have all important parts covered, after all, the JIT version is working well.
I suspect a bug either in the angular-hybrid package or in the way rollup is resolving the package.
To make it apparent I have created a minimal example derived from the minimal example of angular-hybrid here:
https://github.com/ui-router/angular-hybrid/tree/master/example
and applying the steps to make AOT work from the offical angular guidelines page:
https://angular.io/guide/aot-compiler

This way I needed to adjust the package.json, tsconfig.json and main.ts files, and I needed to introduce app,module.ts and rollup-config.js files, all of which can be found adjusted inside this plunker:
https://plnkr.co/edit/tmViEDxH7PFaQkL0qKU7?p=info

The result of running rollup on the AOT compiled code is this error mesaage:

uirouter/angular-hybrid is imported by src\app.module.js, but could not be resolved - treating it as an external dependency

I would really appreciate any help here as this is a stopper for our application if we should rely on using ui-router.

@JiriPelnar can you provide instructions on how to reproduce the error message? perhaps put it in a git repo that I can clone, run yarn && ngc && rollup -c rollup-config.js or whatever the instructions should be?

If I can reproduce it in the plunker, please provide step by step instructions

[JiriPelnar]

Thank you @christopherthielen for looking into this issue. The problem may be on my part, as I might still be missing something, but I am unable to figure out what that could be. However, I put together this repository with the necessary steps to reproduce the rollup error explained in detail in its readme.

Also, please note this answer from @Radim-Kohler to my question related to the same issue on stack overflow. Adjusting the rollup-config the way proposed in the answer makes the rollup step work just fine and it makes me think that maybe the structure of angular-hybrid package can be changed to work with rollup without this special configuration in rollup-config.

I just released ver 3.1.4 which should resolve this.

[JiriPelnar]

Thank and thank you very much for doing this amazing library. I have tested the version 3.1.4 and it indeed works for the angular-hybrid case. I believe a similar fix is also needed for uirouter/core, for which I still need to keep the custom resolver in rollup config in place.
