# Vercel Web Analytics Implementation Report ## Summary Successfully installed and configured Vercel Web Analytics for the KeplerLab vanilla HTML/JavaScript project. ## Changes Made ### 1. Created Package Management Structure **Files Created:** - `web/package.json` - Added npm package configuration for the web directory - `web/package-lock.json` - Lock file for dependency management **Package Installed:** - `@vercel/analytics@^2.0.1` - Official Vercel Web Analytics package ### 2. Configured Web Analytics in HTML **File Modified:** - `web/index.html` - Added Vercel Web Analytics initialization scripts **Changes:** - Added initialization script that creates the `window.va` function for queueing analytics events - Added deferred script tag for `/_vercel/insights/script.js` which will be served by Vercel when deployed - Added clarifying comments to distinguish between Speed Insights (already present) and Web Analytics (newly added) ## Implementation Details ### Approach Taken Since this is a vanilla HTML/JavaScript project without a build system or framework, I followed the official Vercel documentation for vanilla HTML implementations: 1. **Fetched Latest Documentation**: Retrieved the current installation guide from https://vercel.com/docs/analytics/quickstart to ensure up-to-date implementation 2. **Identified Project Type**: Confirmed this is a vanilla HTML project (no React, Next.js, Vue, etc.) 3. **Selected Appropriate Method**: Used the script tag approach recommended for vanilla HTML projects 4. **Installed Package**: Added `@vercel/analytics` package for documentation and potential future programmatic usage ### Script Tag Implementation The implementation uses two script tags in the HTML `<head>`: ```html <!-- Vercel Web Analytics --> <script> window.va = window.va || function () { (window.vaq = window.vaq || []).push(arguments); }; </script> <script defer src="/_vercel/insights/script.js"></script> ``` **How It Works:** 1. The first inline script creates a queue function (`window.va`) that stores analytics calls until the main script loads 2. The deferred script tag loads the actual analytics script from `/_vercel/insights/script.js` 3. Vercel automatically serves this script when the site is deployed and Web Analytics is enabled in the dashboard ### Existing Speed Insights Preserved The project already had Vercel Speed Insights installed via: ```html <script defer src="https://cdn.vercel-insights.com/v1/script.js"></script> ``` This was preserved and labeled with a comment. Speed Insights (performance metrics) and Web Analytics (visitor tracking) are complementary products that work together. ## Next Steps for Deployment When deployed to Vercel, Web Analytics will automatically work if: 1. Web Analytics is enabled in the Vercel project dashboard 2. The site receives visitor traffic The analytics data will appear in the Vercel dashboard under the Analytics section. ## Testing - ✅ Verified HTML structure is valid - ✅ Tested local server still works correctly with updated HTML - ✅ Confirmed no build errors - ✅ Package installation completed successfully - ✅ Lock file generated for consistent dependency resolution ## Notes - No build step is required for this vanilla HTML project - The `@vercel/analytics` package is installed but not directly imported in the code (vanilla HTML uses script tags instead) - The package provides documentation and can be used for future enhancements if a build system is added - Web Analytics uses a different endpoint (`/_vercel/insights/script.js`) than Speed Insights - Both analytics products can coexist and provide different insights (Speed Insights = performance, Web Analytics = visitor tracking) Co-authored-by: Vercel <vercel[bot]@users.noreply.github.com>
