🎁 validateProvidedData Hook

Introducing the validateProvidedData Hook

The validateProvidedData hook is just like validate.form, but it only validates the attributes from the schema which are actually present in the request's data object. In short, it allows partial validation of the schema attributes. Using it as a hook looks like this:

const validate = require('@featehrs-plus/validate-joi')
const attrs = require('./faqs.model')

const hooks = {
  before: {
    patch: [
      validate.validateProvidedData(attrs, { abortEarly: false })
    ]
  }
}

The above example supposes that you have an /faqs service with a model that looks like the following. Notice how the attrs are defined as a separate object, then they are used in the schema and made available in the export. The validateProvidedData hook uses the individual attrs to validate each individual item in the request's data object.

// src/services/faqs/faqs.model.js
const Joi = require('@hapi/joi')
const { objectId } = require('@feathers-plus/validate-joi-mongodb')

const attrs = {
  _id: objectId(),
  question: Joi.string().disallow(null).required(),
  answer: Joi.string().disallow(null).required(),
  isPublic: Joi.boolean().default(false),
  createdBy: objectId().disallow(null).required()
}

module.exports = {
  attrs,
  schema: Joi.object(attrs)
}
