Subject: [PATCH] Add Vercel Web Analytics to SvelteKit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

## Vercel Web Analytics Installation and Configuration

### Summary
Successfully installed and configured Vercel Web Analytics for the SvelteKit project.

### Changes Made

#### 1. Package Installation
- Installed `@vercel/analytics` package using npm
- Updated `package.json` to include the new dependency
- Updated `package-lock.json` with resolved dependencies

#### 2. Analytics Configuration
**Created:** `src/routes/+layout.ts`
- Imported `dev` from `$app/environment` to detect development mode
- Imported `injectAnalytics` from `@vercel/analytics/sveltekit`
- Called `injectAnalytics({ mode: dev ? 'development' : 'production' })` to initialize analytics with environment-aware mode

### Implementation Details
The analytics injection was added to the root layout file (`+layout.ts`) rather than the Svelte component (`+layout.svelte`) to follow SvelteKit best practices. The `+layout.ts` file runs before the component is mounted, ensuring analytics is initialized early in the application lifecycle.

The configuration uses the `dev` environment variable to automatically switch between development and production modes, ensuring proper tracking behavior in different environments.

### Verification
- ✅ Build completed successfully (`npm run build`)
- ✅ Type checking passed with no errors or warnings (`npm run check`)
- ✅ Lock file properly updated to include all dependencies
- ✅ No build artifacts staged (only source code changes)

### Files Modified/Created
1. `package.json` - Added @vercel/analytics dependency
2. `package-lock.json` - Updated with resolved dependencies
3. `src/routes/+layout.ts` - Created new file with analytics configuration

### Notes
The implementation preserves all existing code structure. The root layout Svelte component (`+layout.svelte`) remains unchanged, with analytics configuration cleanly separated in the TypeScript layout file.
