systemjs - Paths with wildcard -

i'm using systemjs. here config:

system.config({     defaultjsextensions: true,     paths: {         app: '/app/*',//for app in app         '*': '/node_modules/*' //for rest in node_modules     }, }); system.import('app/boot')         .then(null, console.error.bind(console)); 

with config browser looking file in node_modules/app/boot.js - why? app should in /app/*
