Real-time search is a must-have feature for today’s web apps. Whether you’re filtering products, users, or suggestions, users expect instant, accurate feedback as they type. But there’s a sneaky problem: Every single keystroke can trigger a new HTTP request. This floods your network with unnecessary calls and can cause your UI to glitch with outdated […]

If you’ve been using Angular for a while, you’re probably familiar with the good old *ngIf + ng-template combo. It worked, but let’s be honest — it wasn’t exactly elegant. <div *ngIf=”isLoggedIn; else guestBlock”> Welcome back, user! 🎉</div><ng-template #guestBlock> Please log in to continue. 🔒</ng-template> Looks familiar? Now with Angular 19, there’s a much better

If you’re still using the classic *ngFor directive, it’s a good time to look into Angular’s newer, cleaner way to loop through data — the @for block. Not only is it easier to read, but it also performs better and feels more like the modern frameworks we all admire (hello React and Svelte 👋). ✨

One of the reasons Angular is such a powerful SPA framework is its flexible routing system. A big part of that flexibility comes from route parameters—those dynamic bits of the URL that help your components respond to context. Whether you’re building an e-commerce product page, a blog, or a user dashboard, route parameters let your

Cross-Site Scripting (XSS) is one of the most common and dangerous web vulnerabilities. The good news? Angular is designed with security in mind — and it goes a long way to protect you right out of the box. But that doesn’t mean you can relax completely. Let’s break down how Angular defends against XSS, where

Angular handles most change detection automatically — from button clicks to HTTP calls — so most of the time, you don’t have to think about it. But sometimes, you need full control. Maybe you’re integrating a third-party library, using Web Workers, or optimizing a high-performance app. In such cases, triggering change detection manually can give

With Angular 16 and newer (especially Angular 19), the framework has entered a new era of reactivity. The introduction of signals, computed, and effect() marks a shift away from traditional component lifecycle hooks. If you’ve been using ngOnChanges() for detecting input changes, it’s time to consider whether effect() might be a cleaner, more modern alternative.

When building complex Angular applications, performance is everything. One powerful but often underused tool in Angular’s arsenal is NgZone. If you’ve ever wondered how to fine-tune change detection and make your app snappier, this is for you. In this guide, I’ll walk you through how NgZone works, how to use it effectively, and when to

Angular’s routing system keeps getting better, and with Angular 19, CanMatch has stepped up as a powerful tool for controlling access to routes—even before they’re activated. If you’re still relying only on CanActivate, it might be time to upgrade your strategy. In this article, I’ll walk you through what’s new with CanMatch in Angular 19,

In any modern Angular application, controlling access to routes is more than just a best practice—it’s essential for security and a smooth user experience. That’s where CanActivate comes in. Whether you’re protecting admin dashboards, user profiles, or feature pages, CanActivate lets you guard routes and restrict access based on conditions like authentication status or user
