ember-changeset-hofs

Higher-order validation functions for ember-changeset-validations.

For background info, please see the thread here.

This addon provides and and or higher-order functions, that allow you to compose together validations. It is useful if you want the short-circuit behavior of && and ||. For example:

// app/validations/user.js
import and from 'ember-changeset-hofs/utils/and'
import or from 'ember-changeset-hofs/utils/or'

export const {
  email: and(
    validateFormat({ type: 'email' }),
    askServerIfExists(), // will not get called if validateFormat fails
  ),

  anotherEmail: or(
    isUndefinedOrNull(),
    askServerIfExists(), // will not get called if isUndefinedOrNull succeeds
  ),
}

Note that the and and or utils work with both synchronous and asynchronous validators.
