v5.0.2

• #42 removes change event listener, so auto-check now only happens on input events. This means if your app was previously programmatically changing input value and firing change event to trigger an auto-check call, you'd need to update the code to fire input instead.

v5.0.1

• remove early exit when same value is entered in input (#41)

<auto-check> element

An input element that validates its value against a server endpoint.

Installation

$ npm install --save @github/auto-check-element

Usage

import '@github/auto-check-element'

<auto-check src="/signup_check/username" csrf="<%= authenticity_token_for("/signup_check/username") %>">
 <input>
</auto-check>

Provide a URL and a CSRF token and the autocheck component will show validation confirmations and validation errors.

The endpoint should respond to POST requests with:

• a 200 HTTP status code if the provided value if valid.
• a 422 HTTP status code if the provided value is invalid.
• a optional error message in the body and a Content-Type header with a value of text/html; fragment.

Events

const check = document.querySelector('auto-check')

// Network request lifecycle events.
check.addEventListener('loadstart', function(event) {
  console.log('Network request started', event)
})
check.addEventListener('loadend', function(event) {
  console.log('Network request complete', event)
})
check.addEventListener('load', function(event) {
  console.log('Network request succeeded', event)
})
check.addEventListener('error', function(event) {
  console.log('Network request failed', event)
})

// Auto-check result events.
const input = check.querySelector('input')

input.addEventListener('auto-check-send', function(event) {
  console.log('Adding to FormData before network request is sent.')
  const {body} = event.detail
  body.append('custom_form_data', 'value')
})
input.addEventListener('auto-check-success', function(event) {
  const {message} = event.detail
  console.log('Validation passed', message)
})
input.addEventListener('auto-check-error', function(event) {
  const {message} = event.detail
  console.log('Validation failed', message)
})
input.addEventListener('auto-check-complete', function(event) {
  console.log('Validation complete', event)
})
