reCAPTCHA2
Easy verifier for Google reCAPTCHA version 2 for Node.js
How to use
Step 1: Setup reCAPTCHA on your site
You need to receive your site key and secret key for your domain from https://www.google.com/recaptcha/intro/.
Follow the steps on this page to include the reCAPTCHA on your website.
Step 2: Initialize verifier
var reCAPTCHA = ; var recaptcha = siteKey: 'your-site-key' // retrieved during setup secretKey: 'your-secret-key' // retrieved during setup ssl: false // optional, defaults to true. // Disable if you don't want to access // the Google API via a secure connection;
Step 3: Verifying the reCAPTCHA response
reCAPTCHA2 uses promises to validate the reCAPTCHA response, you can use one of the following methods:
- please mention on catch, library passes error codes from google which you can translate with translateErrors method
Simple usage:
recaptcha ;
Optional: You can also pass the clients IP address to the validate method after the key. For more information on that, please see the reCAPTCHA documentation.
For use with Express (you need body-parser):
{ recaptcha ;}
Generating the reCAPTCHA widget
recaptcha.formElement()
returns standard form element for reCAPTCHA which you should include at the end of your html form element.
You can also set CSS classes like this: recaptcha.formElement('custom-class-for-recaptcha')
.
The default class is g-recaptcha
.
