I published an update on this tutorial that greatly simplifies everything:
Setup Bootstrap Sass with Laravel Elixir

@ericbarnes Your new article about including bootstrap -sass is great! I just tried it, because my way of including front-end dependencies was... well.... shit :) However, I'm still curious if there is a way to implement font-awsome in a similar fashion (with npm). Or do I need to stick with bower?

after that installation ,how can i include bootstrap template into my application??
