invisible-recaptcha

A simple Express wrapper for Google's invisible Recaptcha.

Installation

npm install --save invisible-recaptcha

Usage

Requires secret reCaptcha key provided by Google. Returns a router to be used as middleware. Please note that this wrapper does not configure the body-parser middleware, so you must do that yourself. Note that you're responsible for getting the client-side data and POSTing it to the endpoint.

Parameters

recaptchaRouter(secretKey, callbackSuccess, callbackFail, options)

The request and response of the POST is passed to both callbacks, ie:

function callbackSuccess(req, res) {}
function callbackFail(req, res) {}

Examples

const express = require('express');
const recaptchaRouterFactory = require('invisible-recaptcha');
const bodyParser = require('body-parser');
const SECRET_KEY = "SECRET";
const app = express();
 
const recaptchaRouter = recaptchaRouterFactory(SECRET_KEY, captchaSuccess, captchaFail);
 
function captchaSuccess(req, res) { res.send('reCaptcha success!') }
function captchaFail(req, res) { res.send('reCaptcha failed.') }
 
app.use(bodyParser.urlencoded({ extended });
app.use('/myEndpoint', recaptchaRouter);

More in-depth examples to come soon.

Options

• options.sendIp - Boolean. The Google's reCaptcha API doesn't require the client's IP address; it's optional. Defaults to true.
• options.usingProxy - Boolean. If options.sendIp is true, then you must specify whether you're using a reverse proxy. Defaults to false.

The creator, nor the project are in any way associated with Google. Also, this is my first public NPM package, so please be gentle ;)
