recaptcha-v3

A simple and easy to use reCAPTCHA (v3 only) library for the browser. (You may be also interested in wrapper libraries)

Install

With NPM:

$ npm install recaptcha-v3

With Yarn:

$ yarn add recaptcha-v3

Prerequisites

To use this package you only need a valid site key for your domain, which you can easily get here.

Usage

With promises:

import { load } from 'recaptcha-v3'

load('<site key>').then((recaptcha) => {
  recaptcha.execute('<action>').then((token) => {
      console.log(token) // Will print the token
    })
})

With async/await:

import { load } from 'recaptcha-v3'

async function asyncFunction() {
  const recaptcha = await load('<site key>')
  const token = await recaptcha.execute('<action>')

  console.log(token) // Will also print the token
}

Loader options

The loader takes care of loading the reCAPTCHA script from Google. Therefore the loader offers optional options for additional configuration:
| Name | Description | Type | Default value | | ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | ------------- | | useRecaptchaNet | Due to limitations in certain countries it's required to use recaptcha.net instead of google.com. | boolean | false | | useEnterprise | Uses the enterprise version of the recaptcha api and handles the differences in the response. | boolean | false | | autoHideBadge | Will automatically hide the reCAPTCHA badge. Warning: The usage is only allowed if you follow the offical guide for hiding the badge from Google (see here) | boolean | false | | renderParameters | Will add the given parameters to the reCAPTCHA script. The given object will be converted into a query string and will then be added to the URL. | Object | {} | | explicitRenderParameters | Will set the parameters to the explicit rendering. See here | Object | {} |

Load options usage

To use the options just pass an additional object to the load(...) method. For example:
```javascript import { load } from 'recaptcha-v3'
load('', { useRecaptchaNet: true, autoHideBadge: true }).then((recaptcha) => {
}) ```

Explicit render parameters

The ReCaptcha widget will be explicity loaded, which means you can add parameters to the rendering process.
| Name | Description | Type | | ---- | ----------- | ---- | | container | The container if you want to render the inline widget | string or Element | | badge | The positioning for the widget | 'bottomright' or 'bottomleft' or 'inline' | | size | The size of the widget | 'invisible' | | tabindex | The tab index of the widget | number |
