Installation

Usage

You can use this package in your Node.js (or NestJS, ExpressJS, etc.) project to validate the user's response to the CAPTCHA.
The package exports a single function validateToken which takes arguments listed below and returns a Promise.

Argument	Type	Description	Required
token	string	The token returned by the CAPTCHA widget.	YES
secretKey	string	Your CAPTCHA project secret key.	YES
apiURL	string	The API URL to use (default: https://api.swetrix.com/captcha), this one may be used in case you're selfhosting the API.	NO

Here's an example of how to use the package in your project:

const { validateToken } = require('@swetrix/captcha-validator')
// or
import { validateToken } from '@swetrix/captcha-validator'

// somewhere inside the controller of your form where the CAPTCHA is used
validateToken(
  'CAPTCHA_TOKEN',
  'YOUR_SECRET_KEY',
).then((result) => {
  const [status, data] = result
  // status is a boolean, true if the token is valid, false otherwise
  // data is an error message if status is false
  console.log(status, data)
})
