### Google Consent Mode v2
We're happy to announce that we now support GCMv2. To use any of the Google trackers you need to manage the Google consent cookies (see config example above). If you fail to update the consent cookies the Google trackers will be initialized with the default values thus preventing most of the tracking.

```javascript
  ad_storage: "denied",
  analytics_storage: "granted",
  functionality_storage: "granted",
  personalization_storage: "denied",
  ad_user_data: "denied",
  ad_personalization: "denied",
  security_storage: "granted",
  wait_for_update: 500
```

Google tools will not work properly if the consent cookies are not set correctly. The plugin will not set the cookies for you. You need to manage the cookies in your cookie banner.


## 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 tracking code by default to the `<head>/<body>` 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 cookies for the tracker you want to use - `gatsby-gdpr-google-analytics`, `gatsby-gdpr-google-tagmanager`, `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 Google Tag Manager and Facebook Pixel. The plugin will check if cookies for Google Analytics or Facebook Pixel have been set between route changes on `onRouteUpdate`. Reloading the page after setting the cookies is not required anymore.

The page view will be tracked on `onRouteUpdate`.

## Initialize and track
This gatsby plugin now supports initializing and tracking right after a user accepts the cookie consent.

```javascript
// in your cookie banner
import { useLocation } from "@reach/router" // this helps tracking the location
import { initializeAndTrack } from 'gatsby-plugin-gdpr-cookies'
```
Then you can execute `initializeAndTrack(location)` in your cookie banner callback. This will initialize the plugin with your options from the `gatsby-config.js` and then starts tracking the user based on the cookies/services are accepted.

```javascript
// in your cookie banner
const location = useLocation()
initializeAndTrack(location)
```
