Install DataSag on React with Vite

Add DataSag to React with Vite through the head of the root index.html. Create a project first, then replace the example public key with the key from your dashboard.

Where to put the tracking script

Open the root index.html that Vite uses as its entry point. Paste the script into head once, outside the React component tree. Build and deploy the app, then inspect the deployed HTML. The tracker is a browser script and needs no npm package.

<script defer src="https://www.datasag.com/tracker.js" data-datasag-key="YOUR_PUBLIC_KEY"></script>

The project tracking key is public and belongs in this snippet. Account credentials, provider API keys and database secrets do not. Keep your existing consent choices and only load analytics when your site's policy permits it.

Verify the published installation

  1. Publish the change to the domain visitors actually use. Open a nested page as well as the homepage.
  2. In browser developer tools, find one tracker.js script with the correct data-datasag-key value.
  3. Filter Network requests for /api/track. Confirm that a pageview payload names the path you opened and receives a successful response.
  4. Open the same DataSag project and choose a date range containing your test. Confirm the page appears before measuring campaigns or conversions.

Avoid this React with Vite setup mistake

A React effect can run more than once during development or component remounts. Avoid inserting the tracker from useEffect when index.html already contains it. Development activity is not a substitute for checking the production build.

Keep pageviews separate from scroll, click and engagement events. A page can generate several tracking requests while still representing one visit to that path.

Events and conversions

Put the call in the React onClick handler for a click goal, or the resolved form action for a completed conversion. Do not call it while rendering JSX.

<a href="/signup" data-datasag-goal="signup_click">Create account</a>

This attribute measures a click. To record a completed signup, call window.datasag.track in the application's confirmed success handler. Current plan details determine which event and campaign reports are available.
