For vue-devtools see https://github.com/vuejs/vue-devtools

we don't need to show the method name as it will only
always show the es6 node core module of node an not
the actual method in our vue application.

as vue-resource is retired from official recommendation status
we switch to axios, which is better maintained and supports a
similar API.
