Usage

SystemJS config

System.config({
    map: {
        'angular2-recaptcha': 'node_modules/angular2-recaptcha'
    },
    packages: {
        app: {
            format: 'register',
            defaultExtension: 'js'
        },
        'angular2-recaptcha': {defaultExtension: 'js', main:'index'}
    }

...
 ...
@NgModule({
  imports: [...,ReCaptchaModule]
  })
  ...

View

Use in template like below

 <re-captcha site_key="<GOOGLE_RECAPTCHA_KEY>"></re-captcha>

Where site_key is the Google reCaptcha public key. Optional parameters as follows:

  • language One of the ISO language values supported by Google: https://developers.google.com/recaptcha/docs/language Note that due to the design of the reCaptcha API, only the first component on a page can change the language from default English.
  • theme Either light (default) or dark.
  • type Either image (default) or audio.
  • size Either normal (default), compact or invisible.
  • tabindex Tabindex for navigation, default 0.

Callback

To catch the success callback, you will need to subscribe to the captchaResponse event. The response token will be passed in the $event parameter.

<re-captcha (captchaResponse)="handleCorrectCaptcha($event)" site_key="<GOOGLE_RECAPTCHA_KEY>"></re-captcha>

The event captchaExpired is triggered when the displayed image has expired. It does not have any event parameters.

Methods

To access the methods, use @ViewChild.

Import

import { ViewChild } from '@angular/core';
import { ReCaptchaComponent } from 'angular2-recaptcha';
 
export class RegisterComponent {
  @ViewChild(ReCaptchaComponent) captcha: ReCaptchaComponent;
}
