FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package typo3-chatixy

Chatixy AI Support Agent - TYPO3 extension

Adds the Chatixy AI support agent to every front-end page of a TYPO3 site. Install, paste your widget key, save. No TypoScript, no template edits, no partial to include.

Requirements
TYPO3 12.4 LTS or 13 LTS (typo3/cms-core: ^12.4 \|\| ^13.4; TER constraint 12.4.0-13.4.99)
PHP whatever your TYPO3 version already requires - the extension adds no floor of its own
Chatixy account any plan; a widget key is all the extension needs

Extension key: chatixy.

Install

Then go to Admin Tools -> Settings -> Extension Configuration -> chatixy, paste the Widget key from your Chatixy dashboard (under Install), and save. Flush the front-end cache and open your site.

The field accepts any of the three shapes the dashboard hands out:

The first 64-character hex run is extracted from whatever you paste, and the value is lower-cased for you. Leave it empty and the extension does nothing at all.

What it does

A PSR-14 listener (registered with the #[AsEventListener] attribute, identifier chatixy/inject-loader) on AfterCacheableContentIsGeneratedEvent splices one tag into the rendered page before the closing </body>:

That is the whole payload. Nothing is added to <head>, no CSS, no extra requests from the server side. The src is HTML-escaped before it is inserted.

Caching

The listener runs on the cacheable content event, so the tag is part of the page content TYPO3 stores in its page cache - there is no per-request PHP cost on a cache hit. The consequence is that changing the key means flushing the front-end cache, or the site keeps serving pages built with the old one.

Notable behaviour

All of this is in Classes/EventListener/InjectLoader.php:

Settings

One field. ext_conf_template.txt declares widgetKey and nothing else.

There is deliberately no host setting - see below. If a host value survives in an existing install's EXTENSIONS/chatixy configuration it is harmless, because nothing reads it.

Security: the origin is pinned

The widget key is public; the host is not configurable. There is no "advanced host" field and no environment variable, because the stored host would build a first-party <script src> on every page of the site - i.e. site-wide stored XSS if it could be influenced. Every loader URL still goes through ChatixyKey::sanitizeHost() as a single choke point, and that method ends in an allow-list: only an https origin whose host is chatixy.com or a subdomain of it is accepted, and anything else is replaced with https://chatixy.com. The pattern is anchored at both ends and requires a literal dot before the canonical domain, so evilchatixy.com, chatixy.com.evil.example, [email protected] and http://chatixy.com are all rejected.
