module.exports = function api(options) {
var seneca = this

seneca.add('role:api,info:hello', hello)

seneca.add('role:api,product:star', get_star)
seneca.add('role:api,product:handle_star', handle_star)

seneca.add('init:api',function(args,done){

// Order is significant here!

seneca.act('role:web',{use:{
prefix:'/',
pin:'role:api,info:*',
map:{
hello:true
}
}})

seneca.use(
{name:'jsonrest-api',tag:'product'},
{
prefix: '/',
list: {embed:'list'},
pin: { name:'product' },
startware: verify_token,
allow_id: true
})

map:{

alias:'/:id/star'
},

DELETE:true,
alias:'/:id/star'
}
}
}})

done()
})

var statusCodes = require('seneca-web-http-status');

// Hard coded token for this example!!!
if( '1234' == token ) return next();

res.writeHead(401,"Access denied.")
res.end()
}


function hello( args, done ) {
done(null,{msg:'hello!'})
}

function get_star( args, done ) {

})
})
}

function handle_star( args, done ) {
this.act(
'role:product,cmd:star',
{
// product id
id:args.id,

// PUT means star, DELETE means unstar
star:('PUT'===args.req$.method)
},

function(err,res){
