// In your gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: `gatsby-plugin-gdpr-cookies`,
      options: {
        googleAnalytics: {
          trackingId: 'YOUR_GOOGLE_ANALYTICS_TRACKING_ID',
          // Setting this parameter is optional
          anonymize: true
        },
        facebookPixel: {
          pixelId: 'YOUR_FACEBOOK_PIXEL_ID'
        },
        // Defines the environments where the tracking should be available  - default is ["production"]
        environments: ['production', 'development']
      },
    },
  ],
}

How it works

First of all the plugin checks in which environment your site is running. If it's currently running in one of your defined environments it will add the Facebook Pixel javascript by default to the <head> of your site. It will not be activated or initialized by this.

By default this plugin will not send any data to Google or Facebook to make it GDPR compliant. The user first needs to accept your cookie policy. By accepting that you need to set two cookies - gatsby-gdpr-google-analytics and gatsby-gdpr-facebook-pixel. Depending on the user input the value of each of the cookies should be true or false.

If the gatsby-gdpr-google-analytics cookie is set to true, Google Analytics will be initialized onClientEntry. Same is for the Facebook Pixel.

The page view will then be tracked on onRouteUpdate.

Important: Please keep in mind to set the cookies. Otherwise the tracking won't work! Tracking won't happen at all if there are no cookies or they are set so false.

Options

Google Analytics

`trackingId`

Here you place your Google Analytics tracking id.

`anonymize`

Some countries (such as Germany) require you to use the _anonymizeIP function for Google Analytics. Otherwise you are not allowed to use it. The option adds two blocks to the code:

ga('set', 'anonymizeIp', 1);

If your visitors should be able to set an Opt-Out-Cookie (No future tracking) you can set a link e.g. in your imprint as follows:

<a href="javascript:gaOptout();">Deactivate Google Analytics</a>

Facebook Pixel

`pixelId`

Here you place your Facebook Pixel id.
