A simple Express wrapper for Google's invisible Recaptcha.
npm install --save invisible-recaptcha
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.
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) {}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.sendIp- Boolean. The Google's reCaptcha API doesn't require the client's IP address; it's optional. Defaults totrue.options.usingProxy- Boolean. Ifoptions.sendIpistrue, then you must specify whether you're using a reverse proxy. Defaults tofalse.
The creator, nor the project are in any way associated with Google. Also, this is my first public NPM package, so please be gentle ;)
