DataSag guides · Updated 27 October 2026
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
- Publish the change to the domain visitors actually use. Open a nested page as well as the homepage.
- In browser developer tools, find one tracker.js script with the correct data-datasag-key value.
- Filter Network requests for /api/track. Confirm that a pageview payload names the path you opened and receives a successful response.
- 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.
Setup and troubleshooting recipes
- Verify DataSag analytics on React with Vite
Check the rendered script, public project key, browser requests and first pageview before relying on your analytics.
- Fix DataSag analytics not working on React with Vite
Trace missing website visits through script placement, project keys, exclusions, consent, network delivery and report filters.
- Fix duplicate analytics pageviews on React with Vite
Separate legitimate engagement events from duplicate tracker installations and repeated pageview dispatches.
- Track custom events on React with Vite
Add click goals or completed-action events with DataSag's data attribute and browser JavaScript API.
- Track UTM campaigns on your website
Create consistent tagged links and verify that campaign parameters reach your website and DataSag.
- Measure AI referral traffic on your website
Check visits with observable AI referrers and understand the difference between traffic, citations and LLM visibility.
- Configure CSP for DataSag analytics on React with Vite
Diagnose blocked scripts, beacon requests and image fallbacks without disabling your site's Content Security Policy.
- Exclude your own analytics visits on your website
Use DataSag's browser exclusion switch to keep your testing activity out of future tracked visits.
- Load analytics without blocking rendering on React with Vite
Choose a non-blocking script placement and verify actual loading behavior instead of relying on a fixed speed claim.
