ember-g-recaptcha

Easily integrate Google's reCaptcha in your app as an Ember Component.

This addon only supports Ember 3 or above

Install

Run the following command from inside your ember-cli project:

ember install ember-g-recaptcha

Configure

You need to generate a valid Site Key / Secret Key pair on Google's reCaptcha admin console. Then, you need to set your Site Key in the ENV var on your config/environment.js file, like this:

  var ENV = {
    // ...

    gReCaptcha: {
      jsUrl: 'https://www.google.com/recaptcha/api.js?render=explicit', // default
      siteKey: 'your-recaptcha-site-key'
    }

    // ...
  }

Basic Usage

Add the component to your template like this:

{{g-recaptcha onSuccess=(action "onCaptchaResolved")}}

then in your component or controller 's actions:

  actions: {
    onCaptchaResolved(reCaptchaResponse) {
      this.get('model').set('reCaptchaResponse', reCaptchaResponse);
      // You should then save your model and the server would validate reCaptchaResponse
      // ...
    },
  }

Advanced Usage

Handling Expiration

You know, after some time the reCaptcha response expires; g-recaptcha 's default behavior is to invoke the reset method. But, if you want to perform custom behavior instead (e.g. transitioning to another route) you can pass your custom action via the onExpired property, like this:

{{g-recaptcha onSuccess=(action "onCaptchaResolved")
              onExpired=(action "onCaptchaExpired") }}

then in your component or controller 's actions:

  actions: {
    onCaptchaExpired() {
      // your custom logic here
    },
  }

Triggering Reset

You might want to arbitrarily trigger reCaptcha reset. For example, if your form submission fails for errors on other fields, you might want to force user to solve a new reCaptcha challenge. To do that, first you'll need to grab a reference to g-recaptcha in your template, like this:

{{g-recaptcha onSuccess=(action "onCaptchaResolved")
              ref=(mut gRecaptcha) }}

then you'll be able to invoke resetReCaptcha() method on gRecaptcha property anywhere in your component or controller 's code, like this:

  this.get('gRecaptcha').resetReCaptcha();

onRender Callback

You might want to pass a callback function that will be called after the reCaptcha renders on the page. This is great for things like loading spinners. To do so, you can do something like this:

{{g-recaptcha onSuccess=(action "onCaptchaResolved")
              onRender=(action "onCaptchaRendered") }}

then in your component or controller 's actions:

  actions: {
    onCaptchaResolved() {
      // ...
    },
    onCaptchaRendered() {
      // your custom onRender logic
    }
  }

Customization

You can pass g-recaptcha the following properties:

• theme
• type
• size
• tabIndex
• hl
• badge

Their meaning is described on this official doc. Also have a look at the dummy app's example templates.

Invisible reCaptcha

Invisible reCaptcha requires different key than classic reCaptcha. You need to register a new key with invisible type. More information

In some cases you may want to use reCaptcha in the invisible mode. The only thing you need do is to add size key to g-recaptcha component with invisible value and create a button with submit type, so you will get something like this:

{{g-recaptcha
  onSuccess=(action "onCaptchaResolved")
  size="invisible"
}}

<button {{action "submit"}} type="submit">Hello</button>

Then in your component you need to define submit method which will execute reCaptcha. For example:

actions: {
  submit() {
    window.grecaptcha.execute();
    // Process rest of operations
  }
}

Configuring source JavaScript URL

In some countries, such as China, you may need to customize the source JavaScript URL. Since the google.com domain is blocked in China, you must set the jsUrl in the configuration to use the recaptcha.net. This works outside China as well.

  var ENV = {
    // ...

    gReCaptcha: {
      jsUrl: 'https://recaptcha.net/recaptcha/api.js?render=explicit', // overridden
      siteKey: 'your-recaptcha-site-key'
    }

    // ...
  }

This also requires the backend URL to be set to https://recaptcha.net/recaptcha/api/siteverify. For more information on configuring the jsUrl, see this issue.
