yarn add @corollarium/retvaljs

const Retval = require('@corollarium/retvaljs');

Builds a Retval object with the following properties:

• retvalObj.status = status
• retvalObj.message = message
• for data:
  • if is a single object then merge it with the Retval object
  • else if is a single value then retvalObj.data = data[0]
  • else if has any value then retvalObj.data = data

Throws an exception, with retval.message as the message, if retval.status === false.
