Hi, tried npm install @ionic/app-scripts@beta --save-dev. It works fine, compare to 0.0.36, application start up is much fast especially integrated with firebase which is good! But all ts source files under webpack:// are null (chrome debug mode).
More specifically the sourcemaps aren't working:

Who knows how this can be a quick fix?
@danbucholtz, any ideas? Because of this bug impossible to debug the project.
We'll publish out a beta in the next day or so. In the mean time install @ionic/app-scripts@nightly. The source maps aren't perfect their but they are at least useable.
Thanks,
Dan
Please run npm install @ionic/app-scripts@beta to install the latest. Source map support is there. We are working on getting _better_ source map support in place. I am going to close this issue for now.
Thanks,
Dan
Hi Dan, tried your suggestion, but the source code is compiled js not original ts file. Here is the screen shot: http://prnt.sc/czrslg
@frankpolkm @danbucholtz same here.
0.0.37 => Sourcemaps null.
0.0.37-2 => SourceMaps in js format.
@frankpolkm, @cleever, yes, we are well aware of the issue 馃槃 . We're calling it good enough for now. You can get work done with it. We're working on it.
Thanks,
Dan
