Use Lighthouse to improve your Angular applications

Angular developers often focus on code structure and framework mastery—but end users care most about speed, accessibility, and visibility. This article highlights how tools like Google Chrome’s built-in Lighthouse can help you measure and improve your app’s performance, accessibility, and SEO. By running quick audits and reviewing actionable insights, developers can bridge the gap between technical excellence and real-world user experience.

Subject, BehaviorSubject, and ReplaySubject

Angular’s reactive world revolves around Subjects, but the star is often the BehaviorSubject — why? Because it always starts with a value, and when you subscribe, you immediately get the latest emission (like receiving the current issue of a magazine). Meanwhile, ReplaySubject lets you go further by replaying multiple past values (no default), and a plain Subject is just “live only” — no past, no future. Let’s dig into when and why to use each.

Signals + HTTP = httpResource [Tutorial]

Angular 19.2 rolls out httpResource — an experimental, signal-friendly layer over HttpClient that lets you fetch data reactively. Instead of juggling Observables and state flags, httpResource gives you built-in signals like isLoading() and hasValue(), and it automatically re-fires requests when dependent signals (e.g. page number, query) change.

The Angular Compiler: From Your Code to Browser Code

This article demystifies what Angular actually bundles into your browser—including how your component and template code gets compiled into a hashed, minified main-xxxxx.js file for cache-busting—and shows how disabling optimization in angular.json lets you peek at the more human-readable compiled output.
