Apicase call example

apicase-call.js

import apis from './container.js'

// Note that it always resolves
let res = await apis.go(serviceName, queryData, params)

// You can handle result as before
// But you often do not have to do it 
// because of next features I'll talk about
if (res.ok) {
  console.log('Success')
} else {
  console.log('Fail')
}
