@persona-js/verify

A vanilla JavaScript module to run embedded/hosted flow without any dependencies, against the official npm module which has some dependencies in both internally/externally. Its bundle size is much lighter, interface is more flexible.

⚠️ This package is still in beta and missing some features of the official module and thus, still not recommended using in production.

Install

npx i @persona-js/verify

or load CDN version on the fly. This defines window.Persona where newInquiry, resumeInquiry belongs to.

<script defer src="https://unpkg.com/@persona-js/verify@x.y.z/dist/cdn.js"></script>

Usage

Start a new inquiry

Embedded flow

import { newInquiry } from '@persona-js/verify'

const verificationWithPersona = newInquiry('tmpl_xyzxyzxyz')
verificationWithPersona.start()

Hosted flow

import { newInquiry } from '@persona-js/verify'

const verificationWithPersona = newInquiry('tmpl_xyzxyzxyz')
const url = verificationWithPersona.getHostedFlowUrl() //=> Returns URL for the hosted flow
window.open(url)

Resume a incompleted inquiry

import { resumeInquiry } from `@persona-js/veerify`

const verificationWithPersona = resumeInquiry('inq_abcabcabc')
verificationWithPersona.start()

Prefilling

import { newInquiry } from '@persona-js/verify'

const verificationWithPersona = newInquiry('tmpl_xyzxyzxyz')
verificationWithPersona.prefill({ nameFirst: 'Kengo' })

Also constructor function can accepts prefiling

import { newInquiry } from '@persona-js/verify'

newInquiry('tmpl_xyzxyzxyz', { prefill: { nameFirst: 'Kengo' } })

Event listening

import { newInquiry } from '@persona-js/verify'

const verificationWithPersona = newInquiry('tmpl_xyzxyzxyz')
verificationWithPersona.on('start', (inquiryId) => { /* what I want to do on starting inquiry flow */ })

.prefill, .on is chainnable

import { newInquiry } from '@persona-js/verify'

newInquiry('tmpl_xyzxyzxyz')
  .prefill({ nameLast: 'Hamasaki' })
  .on('complete', (inquiryId) => { /* what I want to do on completing embedded flow */ })
  .on('fail', (inquiryId) => { /* what I want to do on failing embedded flow */ })
  .on('exit', () => { /* what I want to do on exiting embedded flow */ })
  .start()

Preloading

import { newInquiry } from '@persona-js/verify'

const verificationWithPersona = newInquiry('tmpl_xyzxyzxyz')
const preload = verificationWithPersona.preload()

...

// preload is resolved if Persona's content is ready for starting embedded flow without any wait
preload.then(() => verificationWithPersona.start())

ToDo

• Use shadow DOM
• Avoid multiple UI insertions
• Support undocumented events?
  • Like verification-change, country-select...etc
• Support insertion into a specific element on HTML (inline flow)?
• Throw exceptions on unintentional parameters/arguments
• a11y
• ESM build
• Separate down the monolithic index.ts
• License
  • For each module
  • For cdn build
• Test
• Demo
  • Resume inquriy demo
  • Popup events from embedded flow
  • Do with TypeScript
