AFD PCE React Plugin

The AFD Software React plugin allows for easy integration with the AFD Software Postcode Evolution Validation API. The plugin provides a collection of components and hooks that can be added to any React project and with a small amount of configuration which can enable address validation on input on any form, as well as email address and phone number validation.

The components are designed to be as flexible as possible, allowing for easy integration with any form library or custom form implementation, with both controlled and uncontrolled forms supported.

Install

npm install --save @afd-software/pce-react

Quick Start

Below are simple examples that demonstrate how to populate a Postcode field. The full list of available PCE fields can be found in the documentation for the AFD JSON API.

For full examples of how to use the plugin, please see the Storybook

Address Validation

Controlled Fields

import React, { useEffect, useState } from 'react'
import { AFDTypeahead, useAFDAddressValidation, AddressField } from '@afd-software/pce-react'
import type {  AFDTypeaheadOptions } from '@afd-software/pce-react'


const AddressForm: React.FC = () => {
  const afdOptions: AFDTypeaheadOptions = {
    // if you don't yet have credentials please contact [email protected] or call 01624 811712
    id: 'XXXX',
    token: 'XXXX',
    placeholder: 'Search for address'
  }

  // state object for postcode
  const [street, setStreet] = useState('')
  const [town, setTown] = useState('')
  const [postcode, setPostcode] = useState('')

  // get the relevant functions for the useAFDAddressValidation hook
  const { getAFDTypeaheadProps, selectedAddress, fieldVisible } =
    useAFDAddressValidation(afdOptions, 'GB')

  // monitor for changes to the selected address
  useEffect(() => {
    if (!selectedAddress.Street) return
    setStreet(selectedAddress.Street)
  }, [selectedAddress])
  useEffect(() => {
    if (!selectedAddress.Town) return
    setTown(selectedAddress.Town)
  }, [selectedAddress])
  useEffect(() => {
    if (!selectedAddress.Postcode) return
    setPostcode(selectedAddress.Postcode)
  }, [selectedAddress])

  return (
    <>
      <AFDTypeahead {...getAFDTypeaheadProps()} />
      <AddressField visible={fieldVisible('Street')}>
        <input
          type="text"
          value={street}
          onChange={(e) => setPostcode(e.target.value)}
        />
      </AddressField>
      <AddressField visible={fieldVisible('Town')}>
        <input
          type="text"
          value={town}
          onChange={(e) => setTown(e.target.value)}
        />
      </AddressField>
      <AddressField visible={fieldVisible('Postcode')}>
        <input
          type="text"
          value={postcode}
          onChange={(e) => setPostcode(e.target.value)}
        />
      </AddressField>
    </>
  )
}
export default AddressForm

Uncontrolled Fields

import React, { Component } from 'react'
import { AFDTypeahead, useAFDAddressValidation } from '@afd-software/pce-react'
import { AFDTypeaheadOptions } from './AFDOptions'


const AddressForm: React.FC = () => {
  const afdOptions: AFDTypeaheadOptions = {
    // if you don't yet have credentials please contact [email protected] or call 01624 811712
    id: 'XXXX',
    token: 'XXXX',
    placeholder: 'Search for address'
  }

  // ref for the postcode field
  const postcodeRef = useRef(null)

  useEffect(() => {
    registerUncontrolledField('Postcode')
  }, []);

  // get the relevant functions for the useAddressValidation hook
  const { getAFDTypeaheadProps, registerUncontrolledField, fieldVisible } =
    useAddressValidation(afdOptions, 'GB')

  return (
    <>
      <AFDTypeahead {...getAFDTypeaheadProps()} />
      <AddressField visible={fieldVisible('Postcode')}>
        <input
          type="text"
          ref={postcodeRef}
        />
      </AddressField>
    </>
  )
