How to Use in node.js

'use strict'
const joi = require('joi')
const summarize = require('joi-summarize')

const badInput = {
  age: -2,
  name: 42
}
const schema = joi.object().keys({
  age: joi.number().integer().min(0),
  name: joi.string()
})
const result = schema.validate(badInput, {abortEarly: false})
console.log(summarize(result.error))
/* That will log:
Invalid input.
"age" must be larger than or equal to 0.
"name" must be a string.
*/


// To customize the first line message, pass as 2nd argument
console.log(summarize(result.error, 'Unacceptable data'))
/* That will log:
Unacceptable data.
"age" must be larger than or equal to 0.
"name" must be a string.
*/
