Implemented Vercel Speed Insights for HTTPFrequency project.
## Changes Made:
### Modified Files:
1. **frontend/index.html** - Added Vercel Speed Insights script tags to the <head> section
2. **frontend/script.js** - Removed incorrect ES6 module import statement
## Implementation Details:
This is a vanilla HTML/JavaScript project (not using a framework like Next.js or React), so I followed the official Vercel documentation's instructions for HTML/Other Frameworks integration.
### What was added to index.html:
- Speed Insights initialization script that creates the `window.si` function
- Deferred loading of the Speed Insights tracking script from `/_vercel/speed-insights/script.js`
### What was removed from script.js:
- The ES6 module import statement `import { injectSpeedInsights } from '@vercel/speed-insights';` and its invocation
- This import was not functional in a vanilla JavaScript environment without a bundler
## Why These Changes:
1. **Vanilla JavaScript Project**: This project uses plain HTML/JS without any build tools or module bundlers, so the ES6 import syntax wouldn't work in the browser.
2. **Script Tag Approach**: According to Vercel's official documentation, for HTML/vanilla JavaScript projects, the recommended approach is to add script tags directly to the HTML head section.
3. **Automatic Path**: Vercel automatically serves the Speed Insights script at `/_vercel/speed-insights/script.js` after Speed Insights is enabled in the Vercel dashboard.
## Next Steps for Deployment:
1. **Enable Speed Insights in Vercel Dashboard**: Navigate to your Vercel project dashboard, select Speed Insights from the sidebar, and click the Enable button.
2. **Deploy**: Push these changes to your Git repository or deploy using `vercel deploy`. The Speed Insights routes will be available at `/_vercel/speed-insights/*` after deployment.
3. **Monitor Metrics**: After deployment and user visits, access the Speed Insights dashboard through your Vercel project to monitor Core Web Vitals metrics (LCP, FID, CLS, etc.).
## Technical Notes:
- No package.json changes required since this is a vanilla JavaScript project
- No build process or dependencies to install
- The script loads asynchronously (deferred) to avoid blocking page render
- Speed Insights will automatically track Core Web Vitals and page performance metrics
- The tracking is lightweight and won't impact user experience
The implementation follows the latest Vercel Speed Insights quickstart documentation (fetched on May 11, 2026).
