Ask HN: Rails / Grunt integration – how?

Long time Rails[1] user. Have discovered Npm[2], Bower[3], Grunt[4], Yeoman[5] recently. How do I get these excellent tools to play nicely with the Rails ecosystem[6]? Notably Sprockets[7] and Grunt do not seem to see eye to eye?

What strategies have you used? Would love to know.
