gatsby-plugin-google-analytics-data-reporting-api

Description

This is Reporting API plugin to get your page views count from Google Analytics Data API (GA4). I used to use "https://www.gatsbyjs.com/plugins/gatsby-plugin-google-analytics-reporter" for my blog, but it's only support Universal Analytics v4. Since Universal Analytics would be deprecated soon, and I didn't found the replacement for GA4 yet, so I decide to create one.

How to install

1. Make sure you already set up Google Analytics 4 and anything related properly;
2. Enable Google Analytics Data API in your console cloud apis in "https://console.cloud.google.com/apis/library/analyticsdata.googleapis.com";
3. Make sure your Service Account email has "Viewer" permissions. It's on Google Analytics page > Admin > Account Access Management > choose the Service Account Email > View user's Account details on Roles and Data Restrictions > Choose your GA 4 property > Set it as "Viewer";
4. run npm i gatsby-plugin-google-analytics-data-reporting-api;
5. add this to your gatsby-config:

plugins: [{
  //other plugins...

  resolve: `gatsby-plugin-google-analytics-data-reporting-api`,
  options: {
    serviceAccountEmail: process.env.ANALYTICS_EMAIL,
    privateKey: process.env.ANALYTICS_PRIVATE_KEY,
    property: process.env.ANALYTICS_GA4,
    startDate: `2020-01-01`,
    endDate: `yesterday`,
    limit: 100,
    metric: `screenPageViews`,
    desc: true
  }
}]

I recommend you to set the sensitive value above in environment variables, or use "(dot)env" in local for security.

Options

serviceAccountEmail

required. it's your service account email, like [email protected].

privateKey

required. it's your private key from Google cloud console. download the json, and copy and paste the "private_key" here. it's start with "-----BEGIN PRIVATE KEY-----".

property

required. it's your GA4 property id from Google Analytics Page.

startDate

required since v1.3.0. it's based on Google Analytics date value. Could be '30daysAgo', 'today', 'yesterday', or ISO date format (yyyy-MM-dd) like '2022-12-31'. Default value '365daysAgo'. Google changed its API and for version < v1.3.0 using startDate default value will throw error. Since v1.3.0 I encourage to specify your startDate in config or use dynamic value like '365daysAgo'.

endDate

required since v1.3.0. it's based on Google Analytics date value. Could be '30daysAgo', 'today', 'yesterday', or ISO date format (yyyy-MM-dd) like '2022-12-31'. Default value 'today'. Since v1.3.0 I encourage to specify your endDate.

metric

optional. Metric calculation for reporting. Default value is 'screenPageViews' to calculate metric of the number of app screens or web pages your users viewed. Repeated views of a single page or screen are counted. Since v1.1.0 we can use custom metric like 'totalUsers' to calculate based on distinct users, or 'scrolledUsers' to calculate based on total users who scrolled your pages to at least 90% of page. Visit "https://developers.google.com/analytics/devguides/reporting/data/v1/api-schema#metrics" for more info about metric values can be used.

limit

optional. you can skip this option. it's to limit data fetch from the API. Default value is null which means no limit.

desc

optional. you can skip this option. it's boolean value to determine you want to order the result by ascending or descending. Default value is true.

Examples of usage

query the page views like this:

query AnalyticsPageQuery {
    allPageViews(sort: { totalCount: DESC }) {
        nodes {
            path
            totalCount
        }
    }
}

the response would be this:

{
  "data": {
    "allPageViews": {
      "nodes": [
        {
          "path": "/blog/first-blog",
          "totalCount": 190
        },
        {
          "path": "/blog/second-blog",
          "totalCount": 55
        }
      ]
    }
  }
}
