Which module loader for Aurelia2?

Question

I am starting a new typescript project with Aurelia2. It gives me choice between Webpack and Dumber. I don't know what to choose between those two. My requirements for module loaders is:

1. Easy to debug in Chrome (I want to debug typescript files in chrome without struggle) - This is the MOST important
2. Easy to use (I don't want to mess around config files too much. I want to npm install external modules and use it)
3. I want to be able to use external files like images, css , less, external javascript libraries (not installed through npm) without much struggle

Performance is not an issue for me. Please help me choose. Thanks

Update For the point 2. Easy to use... I am currently using Aurelia 1 with Require bundler from the CLI. I've also, briefly used Aurelia 1 with Webpack at the beginning but the experience with it was bad for the 1st point -debugging typescript in browser and debugging generated javascript is a pain. So the problem with Require and Webpack I have is third party libraries like ie. Devexpress, jsTree, libraries that don't use modules... Those libraries don't simply work and I need to change Aurelia configuration files (aurelia.json) to make them work. And finding the exact configuration is a pain for me (trial and error). For webpack, as I remember, I need to change webpack-config.json and know how webpack works for it to find modules.

For the point 3 easily use external files... I use bootstrap themes for my project 90% of time. Themes I buy from WrapBootstrap. Integrating these themes is not easy for me. I don't know how to reference theme files like javascript files used in theme. In Aurelia word i like to use npm to install my libraries, it is very good and easy to do it, but if I get theme javascript files, I can't install them by npm (I don't mean the third party libraries like select2 the theme uses, only the javascript files the theme developer wrote), I cannot simply import them because they are not modules and are not know to Aurelia.

I am not a front-end developer, and I am not close to javascript system. This is why I like to use Typescript. But finding a solution to those problems takes time, time I don't have. I like Aurelia very much and wouldn't change it for any framework around now days.

What I like about Require is that I can do anything with it. Yes it needs configuration but at the and all works. What I like about Webpack is HMR (hot-module-reload).
