Install Vercel Web Analytics

Vercel Web Analytics Integration

Successfully configured Vercel Web Analytics for the mempool Angular application.

Changes Made:

1. Created New File:

• frontend/src/app/services/analytics.service.ts - New Angular service to initialize Vercel Analytics
  • Implements proper environment-aware configuration
  • Uses inject() function from @vercel/analytics package
  • Automatically switches between 'production' and 'development' modes based on environment configuration

2. Modified Files:

• frontend/src/app/app.module.ts - Added AnalyticsService to the providers array
• frontend/src/app/components/app/app.component.ts - Injected AnalyticsService into the root component to ensure it initializes on app startup
• frontend/package.json - Added @vercel/analytics ^2.0.1 to dependencies (was already present, order normalized)
• frontend/package-lock.json - Updated lock file to reflect dependency tree

Implementation Details:

The implementation follows best practices for Angular applications:

1. Service-Based Architecture: Created a dedicated AnalyticsService that encapsulates the Vercel Analytics initialization logic
2. Environment-Aware Configuration: The service automatically detects whether the app is running in production or development mode and configures analytics accordingly
3. Singleton Pattern: The service uses providedIn: 'root' to ensure a single instance across the application
4. Early Initialization: The service is injected into the root AppComponent to ensure analytics are initialized as early as possible in the application lifecycle

Technical Approach:

Since Vercel Analytics doesn't have specific Angular instructions in their documentation, I used their vanilla JavaScript/TypeScript approach with the inject() function. This is the recommended pattern for frameworks without dedicated integrations.

The configuration passes a mode parameter to control whether analytics run in development or production mode:

• Production mode: Full analytics tracking enabled
• Development mode: Analytics can be tested without affecting production data

Verification:

• ✅ TypeScript compilation passes without errors
• ✅ Linter runs successfully with no new errors introduced
• ✅ Package is properly installed (@vercel/analytics@2.0.1)
• ✅ Service is properly registered in Angular's dependency injection system

Next Steps:

To enable Web Analytics on Vercel:

1. Navigate to your Vercel dashboard
2. Select the project
3. Go to the Analytics section
4. Click "Enable" to activate Web Analytics
5. Deploy the application to see analytics data

The analytics will automatically start tracking page views and web vitals once the application is deployed and the feature is enabled in the Vercel dashboard.

Summary by Sourcery

Integrate Vercel Web Analytics into the Angular frontend and ensure it initializes on app startup with environment-aware configuration.

New Features:

• Add an Angular AnalyticsService that initializes Vercel Web Analytics with production or development mode based on environment settings.

Enhancements:

• Register AnalyticsService in the root module and inject it into the root AppComponent to trigger early analytics initialization.

Build:

• Add @vercel/analytics as a frontend dependency and update the package lockfile accordingly.

Code Review

This pull request integrates Vercel Analytics into the application by adding the @vercel/analytics dependency and creating a new AnalyticsService. The service is registered in the AppModule and injected into the AppComponent for initialization. However, the current implementation of AnalyticsService will cause errors during Server-Side Rendering (SSR) because it calls the inject() function—which relies on browser-specific globals—without checking the execution platform. It is recommended to wrap the initialization logic with a check for isPlatformBrowser to ensure compatibility with SSR.

I am having trouble creating individual review comments. Click here to see my feedback.

frontend/src/app/services/analytics.service.ts (1-15)

The inject() function from @vercel/analytics is designed for browser-side execution as it interacts with DOM-specific globals like window. Since this application uses Server-Side Rendering (SSR) and Prerendering (as evidenced by the domino dependency and build:ssr scripts), calling this function directly in the constructor will cause errors (e.g., ReferenceError: window is not defined) when the code executes on the server.

You should wrap the initialization in a check using isPlatformBrowser and the PLATFORM_ID token to ensure it only runs in the browser environment.

import { Injectable, Inject, PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';
import { inject } from '@vercel/analytics';
import { environment } from '../../environments/environment';

@Injectable({
  providedIn: 'root'
})
export class AnalyticsService {
  constructor(@Inject(PLATFORM_ID) private platformId: Object) {
    if (isPlatformBrowser(this.platformId)) {
      // Initialize Vercel Analytics with environment-aware configuration
      inject({
        mode: environment.production ? 'production' : 'development',
      });
    }
  }
}
