Easily integrate Google's reCaptcha in your app as an Ember Component
npm install ember-g-recaptchaEasily integrate Google's reCaptcha in your app as an Ember Component.
Run the following command from inside your ember-cli project:
ember install ember-g-recaptcha
- Ember.js v3.24 or above
- Ember CLI v3.24 or above
- Node.js v12 or above
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:
``js
var ENV = {
// ...
};
ENV['ember-g-recaptcha'] = {
jsUrl: 'https://www.google.com/recaptcha/api.js', // default
sitekey: 'your-recaptcha-site-key',
hl: 'tr', // Ex: Turkish
};
`
Add the component to your template like this:
`handlebars`
then in your component or controller 's actions:
`js`
@action
onCaptchaResolved(reCaptchaResponse) {
this.model.set('reCaptchaResponse', reCaptchaResponse);
// You should then save your model and the server would validate reCaptchaResponse
// ...
}
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:
`handlebars`
@onExpired={{this.onCaptchaExpired}}
/>
then in your component or controller 's actions:
`js`
@action
onCaptchaExpired() {
// your custom logic here
}
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:
`handlebars`
@onSuccess={{this.onCaptchaResolved}}
/>
then you'll be able to invoke reset() method on gRecaptcha property anywhere in your component or controller 's code, like this:
`js`
this.gRecaptcha.reset();
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:
`handlebars`
@onSuccess={{this.onCaptchaResolved}}
/>
then in your component or controller 's actions:
`js
@action
onCaptchaRendered() {
// your custom onRender logic
}
@action
onCaptchaResolved() {
// ...
}
`
Sometimes you want to have the behavior of a reCAPTCHA but without the burden of injecting the downloaded library into your web page. This is particularly useful during tests.
`handlebars`
@onSuccess={{this.onCaptchaResolved}}
/>
Using @skip, you have the power to ignore the reCAPTCHA's real validations but still have the ability to call your success callback.
:warning: This does not work with onError and onExpired.
You can pass g-recaptcha the following properties:
- sitekey
-
-
-
-
-
- *
Their meaning is described on this official doc.
Also have a look at the dummy app's example templates.
\* The skip option is not a official option.
#### 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:
`handlebars
`
Then in your component you need to define submit method which will execute reCaptcha. For example:
`js`
@action
async submit() {
await window.grecaptcha.execute();
// Process rest of operations
}
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.
`js
var ENV = {
// ...
};
ENV['ember-g-recaptcha'] = {
jsUrl: 'https://www.google.com/recaptcha/api.js', // default
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.
