# Service Injection

Haven ensures your website is GDPR-compliant by only injecting third party services once the user has given his consent. So instead of having the following code snippet somewhere in your HTML...

<!-- Google Analytics -->
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),

ga('create', 'UA-XXXXX-Y', 'auto');
ga('send', 'pageview');
<!-- End Google Analytics -->

... you would instead tell Haven to inject this service at runtime. This should be done for all third party services. Haven comes with the following services out of the box:

  • Google Analytics
  • Google Tag Manager
  • Facebook Pixel

# Configuring services

The Haven configuration object takes a list of services:

    services: [],

Each service may specify the following options:

Option Details Required
name Name of the service. The value is used to determine whether a service has already been injected, and should thus be unique. true
purposes List of cookie purposes that apply to this service. The service will only be injected if all of the purposes have been consented to by the user. The purposes available by default are: functional, analytics, marketing, preferences. When specifying custom purposes, please make sure you provide a corresponding translation entry. true
type If you wish to make use of the default injectors provided by Haven, make sure you use one of the following types: google-analytics, google-tag-manager or facebook-pixel. false
inject The value may be a boolean or a custom injector function (see Custom Injectors). When set to true, it will attempt to use a default injector. false
required Boolean value that describes whether the service is required. When true, the service will always be injected, no matter the consent. false
cookies Array of cookie names provided by this service. The names may be strings or regular expressions. Haven will delete these cookies when the user revokes his consent. Cookies for any of the default injectors do not need to be specified here. false
options Optional options passed to the injector function. When using a default injector, specify your Google Analyitcs / Google Tag Manager / Facebook Pixel ID here (options.id) false

# Custom Injectors

The inject property of a given service may also be a function which will then get called by Haven to inject the service once all prerequisites have been met.

    services: [
            name: 'custom-script',
            purposes: ['analytics', 'custom-purpose'],
            inject: () => {
  				const firstScript = document.getElementsByTagName('script')[0];
  				const script = document.createElement('script');
  				script.src = `https://some-custom-script-source`;
  				firstScript.parentNode!.insertBefore(script, firstScript);
