How to Analyze Web Performance of Any Web App—Angular Shorts 🚀
Angular Shorts Quick Tips. Big Impact.
Hi there,
Welcome to Angular Shorts – your go-to source for quick insights into Angular development and web performance!
In today’s fast-paced tech world, analyzing and optimizing web performance is essential. Tools like Chrome DevTools, Lighthouse, and Web Vitals provide powerful ways to measure and enhance your web app’s speed, usability, and stability.
🔍 Why Analyze Web Performance?
Understanding your app's performance helps you:
Spot bottlenecks before users do
Improve load times and responsiveness
Enhance SEO and user experience
Increase overall engagement
A smart approach includes tracking key metrics before and after optimizations, helping you visualize improvements and measure impact.
🛠️ Why Use Chrome DevTools?
Chrome DevTools is more than just a console—it's your performance lab.
With DevTools, you can:
Audit your app with Lighthouse for performance, accessibility, and best practices
Monitor Web Vitals like LCP, FID, and CLS
Debug JavaScript, analyze memory usage, and track paint events
🚀 Angular Snippet: Start Your Performance Analysis
Here’s a quick Angular setup to begin tracking performance metrics (Lighthouse/Web Vitals):
import { ReportHandler } from 'web-vitals';
const sendToAnalytics: ReportHandler = (metric) => {
console.log(metric);
};
import { getCLS, getFID, getLCP } from 'web-vitals';
getCLS(sendToAnalytics);
getFID(sendToAnalytics);
getLCP(sendToAnalytics);
Use this in your main app component or monitoring module to start gathering data!
📊 What Can DevTools Reveal?
DevTools can uncover key performance insights:
Seasonality: Do performance issues spike during specific times?
Anomalies: Identify unusual drops or slowdowns
Trends: Track long-term performance improvements or regressions
🤔 Limitations of DevTools & Lighthouse
While powerful, these tools have their limits:
Lab data ≠ real-world performance
Single-device testing might not reflect broader user base
Requires manual setup to track continuous changes
Use DevTools as part of a broader strategy with real-user monitoring (RUM).
