by example

validate a request

const { parser, schemas } = require('openrtb-schema-validator')
 
const requestValidator = parser(schemas.request['2.5'], { removeAdditional: true })
 
const { error, data } = requestValidator.validate({
  id: '1',
  imp: [{ id: '1' }]
})
 
if (error) {
  console.error(error)
}
cosole.log(data)

validate a response

const { parser, schemas } = require('openrtb-schema-validator')
 
const responseValidator = parser(schemas.response['2.5'], { removeAdditional: true })
 
const { error, data } = responseValidator.validate({
  id: '1',
  seatbid: {
    bid: []
  }
})

modify a schema

const { parser, schemas } = require('openrtb-schema-validator')
 
const schema = schemas.request['2.5'].clone()
schema.root.properties.foo = { type: 'string' }
 
const requestValidator = parser(schema, { removeAdditional: true })
 
const { error, data } = requestValidator.validate({
  id: '1',
  foo: 'bar',
  seatbid: {
    bid: []
  }
})

API

parser(schema, { emitErrors, removeAdditional, coerceTypes, useDefaults })

• schema - an object of type Schema
• options
  • emitErrors - boolean, if set the parser object would emit events of type error whenever validation failed
  • removeAdditional - if there are properties not set in the schema, they would be removed, otherwise validation would failed (from ajv)
  • coerceTypes - force types into data, eg: if a property is defined as string but an integer is provided, that property would be coerced into a string (from ajv)
  • useDefaults - allow defaults values in the schema (from ajv)

schemas[]

• request['2.5']
• response['2.5']
