Google Analytics Badges

https://google-analytics.atanas.info/

Pageviews

Node.js wrapper for a serverless service to generate Shields IO-style badges for Google Analytics. Authenticates with the Reporting API using JWT tokens and uses shields to generate badges for traffic stats. Fully customizable. Works with Universal Analytics but not GA4 properties.

Quickstart

Obtain service account credentials

Google service account credentials are needed for JWT authentication.

  1. Visit Google Cloud Platform > APIs & Services > Credentials or console.cloud.google.com/apis/credentials.
  2. If you do not already have a project. Click Create project and give it a name. Refresh the page if changes aren't showing.
  3. With the project selected, add an API by clicking Dashboard > Enable APIs and services. Find the Google Analytics Reporting API and enable it.
  4. Select Create credentials > Service account, give the account a name. Click continue to skip through the optional steps.
  5. Click your newly created service account and scroll to the Keys section. Select Add key > Create new key > JSON, a file will be downloaded.

Your file will look like this. client_email and private_key are the values you'll need for the next steps.

{
	"type": "service_account",
	"project_id": "PROJECT_ID",
	"private_key_id": "PRIVATE_KEY_ID",
	"private_key": "-----BEGIN PRIVATE KEY-----\nPRIVATE_KEY\n-----END PRIVATE KEY-----\n",
	"client_email": "CLIENT_EMAIL",
	"client_id": "CLIENT_ID",
	"auth_uri": "https://accounts.google.com/o/oauth2/auth",
	"token_uri": "https://oauth2.googleapis.com/token",
	"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
	"client_x509_cert_url": "CLIENT_CERT_URL"
}

Add users to Analytics

To allow the service account access to your analytics data, you need to add it as a user. Full instructions can be found on Google's documentation. A summary of the steps is shown below.

  1. Sign in to Google Analytics. Click Admin > Account User Management.
  2. In the Account permissions list, click +, then click Add users.
  3. Enter the client_email for the service account. In the example file above, this would be eightants@dummydata.gserviceaccount.com.
  4. Make sure the Read & Analyze permission is checked. Then click Add.

Now the setup is complete, time to deploy our serverless functions.

Deployment

This Node.js project was built with serverless hosting in mind. However, it is also possible to integrate this into your current hosted projects.

Integrate into existing Node server

Adapt the code in integrate.js into your existing server code. Full documentation about the Core Reporting API can be found here.

Deploying a serverless instance

Since it requires private keys, the best way is to deploy your own instance of this service. We will be using Vercel for free serverless deployments.

Deploy with Vercel

Automate steps 1-5 with the button above

  1. Fork the https://github.com/eightants/analytics-badge project to your GitHub account.
  2. Create an account on Vercel.
  3. From the dashboard page click Import Project then specify the URL to your fork of the project on GitHub.
  4. Add the required environment variables CLIENT_EMAIL and PRIVATE_KEY. These values correspond to client-email and private-key above.
  5. Deploy and visit your application at <deploy-id>.vercel.app or the custom domain which you configured.

Visit your Google Analytics dashboard and obtain the viewId for your project of interest from Admin > View > View Settings > View ID. You can now generate shields.io badges for any of your Analytics projects with this endpoint.

https://<deploy-id>.vercel.app/api/analytics?viewId=<VIEWID>&metric=<METRIC>&startDate=<STARTDATE>&endDate=<ENDDATE>&title=<TITLE>&unit=<UNIT>&color=<COLOR>&style=<STYLE>&si=<SI>

Query Parameters

Param Description
