Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

BotDetect CAPTCHA AngularJS Module (JavaScript: Angular 1.x)

For a comprehensive step-by-step integration guide please see our AngularJS Captcha Module Integration Guide.
The guide covers the integration with the following backends:

  • ASP.NET (Core): web API with MVC Core
  • ASP.NET (Legacy): Web-API2, MVC1-5, Generic Handler
  • Java: Servlet, Spring, Struts
  • PHP: the plain PHP

To give you a hint how AngularJS Captcha Module works we pasted bellow a few, not necessary up-to-date (and mostly frontend related), excerpts from the Integration Guide.

Quick guide:

1) AngularJS Captcha Module Installation
npm install angularjs-captcha --save
2) Include AngularJS Captcha Module in Your App
<script src="node_modules/angularjs-captcha/dist/angularjs-captcha.min.js"></script>
3) Inject AngularJS Captcha Module to Your AngularJS App, and Configure Backend Captcha Endpoint

Endpoint configuration depends on which technology you use in the backend.

  • ASP.NET-based captcha endpoint:
var app = angular.module('app', ['BotDetectCaptcha']);

app.config(function(captchaSettingsProvider) {
  ...

  captchaSettingsProvider.setSettings({
    captchaEndpoint: 
      'https://your-app-backend-hostname.your-domain.com/simple-captcha-endpoint.ashx'
  });
});
  • Java-based captcha endpoint:
var app = angular.module('app', ['BotDetectCaptcha']);

app.config(function(captchaSettingsProvider) {
  ...

  captchaSettingsProvider.setSettings({
    captchaEndpoint: 
      'https://your-app-backend-hostname.your-domain.com/simple-captcha-endpoint'
  });
});
  • PHP-based captcha endpoint:
var app = angular.module('app', ['BotDetectCaptcha']);

app.config(function(captchaSettingsProvider) {
  ...

  captchaSettingsProvider.setSettings({
    captchaEndpoint: 
      'https://your-app-backend-hostname.your-domain.com/botdetect-captcha-lib/simple-botdetect.php'
  });
});
4) Display Captcha In Your AngularJS Template
<botdetect-captcha captchaStyleName="yourFirstCaptchaStyle"></botdetect-captcha>
<input id="userCaptchaInput"
  type="text" 
  name="userCaptchaInput"
  ng-model="userCaptchaInput" >
5) Captcha Validation: Client-side Code
app.controller('YourFormWithCaptchaController',
    function ($scope, $http, $window, Captcha) {

  // process the form on submit event
  $scope.validate = function () {

    // create new AngularJS Captcha instance
    var captcha = new Captcha();

    // get the user-entered captcha code value to be validated at the backend side        
    var userEnteredCaptchaCode = captcha.getUserEnteredCaptchaCode();

    // get the id of a captcha instance that the user tried to solve
    var captchaId = captcha.getCaptchaId();

    var postData = {
      // add the user-entered captcha code value to the post data
      userEnteredCaptchaCode: userEnteredCaptchaCode,
      // add the id of a captcha instance to the post data
      captchaId: captchaId
    };

    // post the captcha data to the /your-app-backend-path on your backend
    $http({
      headers: { 'Content-Type': 'application/json; charset=utf-8' }
      method: 'POST',
      url: 'https://your-app-backend-hostname.your-domain.com/your-app-backend-path',
      data: postData
    })
      .then(function (response) {
        if (response.data.success == false) {
          // captcha validation failed; reload image
          captcha.reloadImage();
          // TODO: maybe display an error message, too
        } else {
          // TODO: captcha validation succeeded; proceed with the workflow
        }
      }, function (error) {
        throw new Error(error.data);
      });
  };
});
6) Captcha Validation: Server-side Code

The userEnteredCaptchaCode and captchaId values posted from the frontend are used to validate a captcha challenge on the backend.

The validation is performed by calling the: Validate(userEnteredCaptchaCode, captchaId).

// C#
SimpleCaptcha yourFirstCaptcha = new SimpleCaptcha();
bool isHuman = yourFirstCaptcha.Validate(userEnteredCaptchaCode, captchaId);
' VB.NET
Dim yourFirstCaptcha As SimpleCaptcha = New SimpleCaptcha()
Dim isHuman As Boolean = yourFirstCaptcha.Validate(userEnteredCaptchaCode, captchaId)
  • Server-side Captcha validation with Java Captcha looks in this way:
SimpleCaptcha yourFirstCaptcha = SimpleCaptcha.load(request);
boolean isHuman = yourFirstCaptcha.validate(userEnteredCaptchaCode, captchaId);
  • Server-side Captcha validation with PHP Captcha looks in this way:
$yourFirstCaptcha = new SimpleCaptcha();
$isHuman = $yourFirstCaptcha->Validate($userEnteredCaptchaCode, $captchaId);
