Since it's featured in ProcessWire Weekly #310, now is the time to make it official:
Here is Twack!

I really like the following introduction from ProcessWire Weekly, so I hope it is ok if I use it here, too. Look at the project's README for more details!

Twack is a new — or rather newish — third party module for ProcessWire that provides support for reusable components in an Angular-inspired way. Twack is implemented as an installable module, and a collection of helper and base classes. Key concepts introduced by this module are:

  • Components, which have separate views and controllers. Views are simple PHP files that handle the output for the component, whereas controllers extend the TwackComponent base class and provide additional data handling capabilities.
  • Services, which are singletons that provide a shared service where components can request data. The README for Twack uses a NewsService, which returns data related to news items, as an example of a service.

Twack components are designed for reusability and encapsulating a set of features for easy maintainability, can handle hierarchical or recursive use (child components), and are simple to integrate with an existing site — even when said site wasn't originally developed with Twack.

A very basic Twack component view could look something like this:

<?php namespace ProcessWire; ?>
<h1>Hello World!</h1>

And here's how you could render it via the API:

<?php namespace Processwire;
$twack = $modules->get('Twack');
$hello = $twack->getNewComponent('HelloWorld');
?>
<html>
    <head>
        <title>Hello World</title>
    </head>
    <body>
        <?= $hello->render() ?>
    </body>
</html>

Now, just to add a bit more context, here's a simple component controller:

<?php namespace ProcessWire;

class HelloWorld extends TwackComponent {
    public function __construct($args) {
        parent::__construct($args);

        $this->title = 'Hello World!';
        if(isset($args['title'])) {
            $this->title = $args['title'];
        }
    }
}

As you can see, there's not a whole lot new stuff to learn here if you'd like to give Twack a try in one of your projects. The Twack README provides a really informative and easy to follow introduction to all the key concepts (as well as some additional examples) so be sure to check that out before getting started. 

Twack is in development for several years and I use it for every new project I build. Also integrated is an easy to handle workflow to make outputs as JSON, so it can be used to build responses for a REST-api as well. I will work that out in one section in the readme as well. 

If you want to see the module in an actual project, I have published the code of www.musical-fabrik.de in a repository. It runs completely with Twack and has an app-endpoint with ajax-output as well.

I really look forward to hear, what you think of Twack🥳!

Hi, maybe silly question, but could you tell me how to try out you musical-fabric package (how to install it)? There is only SITE folder inside.

Thank you

      This module allows you to integrate hCaptcha bot / spam protection into ProcessWire forms. hCaptcha is a great alternative to Google ReCaptcha, especially if you are in the EU and need to comply with privacy regulations.

      The development of this module is sponsored by schwarzdesign.
      The module is built as an Inputfield, allowing you to integrate it into any ProcessWire form you want. It's primarily intended for frontend forms and can be added to Form Builder forms for automatic spam protection. There's a step-by-step guide for adding the hCaptcha widget to Form Builder forms in the README, as well as instructions for API usage.
      Features
      Inputfield that displays an hCaptcha widget in ProcessWire forms. The inputfield verifies the hCaptcha response upon submission, and adds a field error if it is invalid. All hCaptcha configuration options for the widget (theme, display size etc) can be changed through the inputfield configuration, as well as programmatically. hCaptcha script options can be changed through a hook. Error messages can be translated through ProcessWire's site translations. hCaptcha secret keys and site-keys can be set for each individual inputfield or globally in your config.php. Error codes and failures are logged to help you find configuration errors. Please check the README for setup instructions.

      This module is (yet another) way for implementing a cookie management solution.
      Of course there are several other possibilities:
      - https://processwire.com/talk/topic/22920-klaro-cookie-consent-manager/
      - https://github.com/webmanufaktur/CookieManagementBanner
      - https://github.com/johannesdachsel/cookiemonster
      - https://www.oiljs.org/
      - ... and so on ...
      In this module you can configure which kind of cookie categories you want to manage:

      You can also enable the support for respecting the Do-Not-Track (DNT) header to don't annoy users, who already decided for all their browsing experience.
      Currently there are four possible cookie groups:
      - Necessary (always enabled)
      - Statistics
      - Marketing
      - External Media
      All groups can be renamed, so feel free to use other cookie group names. I just haven't found a way to implement a "repeater like" field as configurable module field ...
      When you want to load specific scripts ( like Google Analytics, Google Maps, ...) only after the user's content to this specific category of cookies, just use the following script syntax:
      <script type="text/plain" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The type has to be "optin" to get recognized by PrivacyWire, the data-attributes are giving hints, how the script shall be loaded, if the data-category is within the cookie consents of the user. These scripts are loaded asynchronously after the user made the decision.
      If you want to give the users the possibility to change their consent, you can use the following Textformatter:
      [[privacywire-choose-cookies]] It's planned to add also other Textformatters to opt-out of specific cookie groups or delete the whole consent cookie.
      You can also add a custom link to output the banner again with a link / button with following class:
      <a href="#" class="privacywire-show-options">Show Cookie Options</a> <button class="privacywire-show-options">Show Cookie Options</button> This module is still in development, but we already use it on several production websites.
      You find it here: PrivacyWire Git Repo
      Download as .zip
      I would love to hear your feedback 🙂

      Cacheable Placeholders
      This module allows you to have pieces of dynamic content inside cached output. This aims to solve the common problem of having a mostly cacheable site, but with pieces of dynamic output here and there.  Consider this simple example, where you want to output a custom greeting to the current user:
      <h1>Good morning, <?= ucfirst($user->name) ?></h1> This snippet means you can't use the template cache (at least for logged-in users), because each user has a different name. Even if 99% of your output is static, you can only cache the pieces that you know won't include this personal greeting. A more common example would be CSRF tokens for HTML forms - those need to be unique by definition, so you can't cache the form wholesale.
      This module solves this problem by introducing cacheable placeholders - small placeholder tokens that get replaced during every request. The replacement is done inside a Page::render hook so it runs during every request, even if the response is served from the template cache. So you can use something like this:
      <h1>Good morning, {{{greeting}}}</h1> Replacement tokens are defined with a callback function that produces the appropriate output and added to the module through a simple hook:
      // site/ready.php wire()->addHookAfter('CachePlaceholders::getTokens', function (HookEvent $e) { $tokens = $e->return; $tokens['greeting'] = [ 'callback' => function (array $tokenData) { return ucfirst(wire('user')->name); } ]; $e->return = $tokens; }); Tokens can also include parameters that are parsed and passed to the callback function. There are more fully annotated examples and step-by-step instructions in the README on Github!
      Features
      A simple and fast token parser that calls the appropriate callback and runs automatically. Tokens may include multiple named or positional parameters, as well as multi-value parameters. A manual mode that allows you to replace tokens in custom pieces of cached content (useful if you're using the $cache API). Some built-in tokens for common use-cases: CSRF-Tokens, replacing values from superglobals and producing random hexadecimal strings. The token format is completely customizable, all delimiters can be changed to avoid collisions with existing tag parsers or template languages. Links
